DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Priority
Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Information Disclosure Statement
The listing of references in the specification is not a proper information disclosure statement. 37 CFR 1.98(b) requires a list of all patents, publications, or other information submitted for consideration by the Office, and MPEP § 609.04(a) states, "the list may not be incorporated into the specification but must be submitted in a separate paper." Therefore, unless the references have been cited by the examiner on form PTO-892, they have not been considered.
Drawings
The drawings are objected to because the labels in Figure 1, in particular the subscripts, are blurry and difficult to read.
The drawings are further objected to as failing to comply with 37 CFR 1.84(p)(5) because they do not include the following reference signs mentioned in the description: rounded grinding cup base 74 and shaft ends 87.
Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Specification
Applicant is reminded of the proper language and format for an abstract of the disclosure.
The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details.
The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided.
The abstract of the disclosure is objected to because it contains more than 150 words and more than one paragraph, as well as implied phraseology (“The invention relates to” in line 1). A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b).
The disclosure is objected to because it contains an embedded hyperlink and/or other form of browser-executable code. Applicant is required to delete the embedded hyperlink and/or other form of browser-executable code; references to websites should be limited to the top-level domain name without any prefix such as http:// or other browser-executable code. See MPEP § 608.01. The embedded hyperlinks are “www.fritsch.de” on pg. 1 para. 1 and “https://de.wikipedia.org/wiki/Drehmatrix” on pg. 25 para. 2.
The disclosure is objected to because of the following informality: on pg. 30 ln 6, “sun axis S1” should read “sun axis S”.
Appropriate correction is required.
Claim Objections
Claims 10, 11, 15, 16, 18, 20, 21, 26, and 30 are objected to because of the following informalities:
Claims 10, 15, 16, 18, 20, and 21: all recitations of “the first and second planetary axis of rotation” should read “the first and second planetary axes of rotation” for grammatical correctness
Claim 11: “a first planetary rotational speed” in line 4 and “a second planetary rotational speed” in line 7 should be amended to “the first planetary rotational speed” and “the second planetary rotational speed”, respectively, as these limitations are previously recited in Claims 1 and 10
Claim 26: all items on the list of structural and dynamic parameters should be preceded by “a” (e.g. “a sun radius”, “a planetary internal radius”, etc.), except for “sun rotational speed” and “first planetary rotational speed” which are already recited in Claim 1 and thus should be preceded by “the”; and in line 17, “the design and dynamic parameters” should be amended to “the structural and dynamic parameters” to match the rest of the claim language
Claim 30: in line 9, “a first planetary rotational speed” should be amended to “the first planetary rotational speed”, as this limitation is already recited in Claim 1
Appropriate correction is required.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 2-7, 9, 22-24, 26-27, 29, and 35 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Regarding Claim 2, the limitation “the rotation plane” does not have antecedent basis in the claim.
Regarding Claim 3, the limitation “the interior” does not have antecedent basis in the claim.
Regarding Claim 4, the scope of the limitation “a sun belt drive for driving the rotation of the carrier device about the sun axis by means of a drive motor” is unclear. Is this meant to further limit the drive which rotatably drives the carrier device about the sun axis recited in lines 4-5 of Claim 1, i.e. by adding structural features, or is this meant to be a separate, additional drive? For examination purposes, the first interpretation will be used.
Regarding Claims 5 and 22, the scope of the limitation “wherein the first planetary synchronous drive drives the rotation of the grinding vessel receiving device about the first planetary axis of rotation” is unclear. Is this meant to further limit the drive for rotatably driving the first grinding vessel receiving device and the grinding vessel about the first planetary axis of rotation recited in lines 14-16 of Claim 1, i.e. by defining it as a synchronous drive, or is this meant to be a separate, additional drive? For examination purposes the first interpretation will be used.
Claims 6 and 23 are rejected by virtue of their dependences upon Claims 5 and 22, respectively.
Regarding Claim 7, the limitation “the relative rotational speed ratio” does not have antecedent basis in the claim.
Regarding Claim 9, the limitation “the radius” does not have antecedent basis in the claim.
Regarding Claim 24, the limitations “the relative rotational speed ratio” and “the rotational speed ratio” do not have antecedent basis in the claim.
Regarding Claim 26, the limitations “the center point” (line 5), “the internal radius” (line 7), “the interior” (line 7), and “the inside wall” line 19 do not have antecedent basis in the claim.
Regarding Claim 27, the limitations “the center point” (line 5) and “ratio” (line 8) do not have antecedent basis in the claim.
Regarding Claim 29, the scope of the limitation “wherein different grinding vessels can be interchangeably inserted into the first grinding vessel receiving device” is unclear. Is this meant to positively recite different grinding vessels which may be interchangeably inserted into the first grinding vessel receiving device, or merely stating that the first grinding vessel receiving device is capable of having different grinding vessels inserted interchangeably therein?
Further regarding Claim 29, the scope of the limitation “in order to reliably brace the grinding cup” in lines 8-9 is unclear because the term “reliably” is a relative term which renders the claim indefinite. The term “reliably” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention.
Regarding Claim 35, the limitation “the first planetary shaft” does not have antecedent basis in the claim. Examiner notes that a first planetary shaft is positively recited in each of Claim 30, but Claim 35 depends from Claim 29, not Claim 30.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-3, 5, 8-10, 15-22, 24-28, and 30 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Gouko et al., hereinafter Gouko (US 2014/0117131, provided by Applicant).
Regarding Claim 1, Gouko discloses (Figures 1-2 and 11) a planetary mill (centrifugal ball mill 10) for comminuting material to be ground, comprising: a sun axis (revolution axis 12) and a carrier device (revolution arm 24) which is mounted so as to be rotatable about the sun axis ([0039] lns 3-5), and a drive (revolution actuator 20) for rotatably driving the carrier device about the sun axis at a sun rotational speed ([0051] lns 2-6), a first planetary axis of rotation (rotation axis 14 in embodiment of Figure 11) and a first planetary grinding station (assembly of container 11, rotation gear 33 and rotation shaft 34 of rotation mechanism 15, and second rotation mechanism 61) having a first grinding vessel receiving device (container fixing member 64) for at least one grinding vessel (container 11) that can be filled with material to be ground and grinding media (crushing balls 50, see Figures 12-13), wherein the first grinding vessel receiving device together with the grinding vessel is mounted on the carrier device so as to be rotatable about the first planetary axis of rotation, eccentrically with respect to the sun axis ([0033] lns 6-8), and is carried along by the carrier device on a planetary orbit (represented by “revolution direction” arrows in Figure 2) around the sun axis when the carrier device rotates about the sun axis ([0033] lns 4-6), a drive (rotation actuator 30) for rotatably driving the first grinding vessel receiving device together with the grinding vessel about the first planetary axis of rotation at a first planetary rotational speed ([0054] lns 1-5), wherein during operation the first planetary grinding station revolves around the sun axis on the planetary orbit together with the first grinding vessel receiving device and the grinding vessel ([0033] lns 4-6), and at the same time the first grinding vessel receiving device rotates about the first planetary axis of rotation together with the grinding vessel ([0053] lns 1-5, [0086] lns 5-6), wherein the first planetary axis of rotation at least at times extends in a skewed manner relative to the sun axis ([0082] lns 3-5).
Regarding Claim 2, Gouko discloses (Figure 11) the first planetary axis of rotation (rotation axis 14) extends in parallel with the rotation plane of the carrier device (rotation plane of revolution arm 24 is perpendicular to revolution axis 12, as indicated by the “revolution direction” arrows in Figure 2; rotation axis 14 is also perpendicular to revolution axis 12, so the first planetary axis of revolution extends in parallel to the rotation plane of the carrier device).
Regarding Claim 3, Gouko discloses (Figure 11) the size of the grinding vessel (container 11) and the eccentric positioning of the first planetary grinding station (assembly of container 11, rotation gear 33 and rotation shaft 34 of rotation mechanism 15, and second rotation mechanism 61) with respect to the sun axis (revolution axis 12) are selected in such a way that the sun axis does not intersect the interior of the grinding vessel, or intersects it only in a peripheral edge region (clearly seen in figure).
Regarding Claim 5, Gouko discloses (Figures 1 and 11) a first planetary synchronous drive (rotation mechanism 15) between the carrier device (revolution arm 24) and the first planetary grinding station (assembly of container 11, rotation gear 33 and rotation shaft 34 of rotation mechanism 15, and second rotation mechanism 61), wherein the first planetary synchronous drive drives the rotation of the grinding vessel receiving device (container fixing member 64) about the first planetary axis of rotation (rotation axis 14), synchronously to the rotation of the carrier device (para. [0052]-[0053] describes synchronous rotation of first planetary grinding station in embodiment of Figure 1, which is analogous to the first planetary grinding station in the embodiment of Figure 11, with the revolution arm 24).
Regarding Claim 8, Gouko discloses (Figures 8-9) an embodiment in which the first grinding vessel receiving device (not shown in figures) together with the grinding vessel (container 11), in addition to the revolution on the planetary orbit around the sun axis (revolution axis 12), rotates merely about one planetary axis of rotation, specifically the first planetary axis of rotation (rotation axis 14), and wherein the first planetary axis of rotation extends so as to be constantly skewed relative to the sun axis ([0076] lns 3-5).
Regarding Claim 9, Gouko discloses (Figures 8-9) the first planetary axis of rotation (rotation axis 14) is permanently transverse to the radius of the planetary orbit (represented by “revolution direction” arrows in Figure 2) of the first planetary grinding station about the sun axis (revolution axis 12; [0077] lns 1-2: rotation axis 14 is permanently inclined relative to revolution axis 12, therefore it is permanently transverse to the radius of the planetary orbit as well).
Regarding Claim 10, Gouko discloses (Figure 11) the first planetary grinding station (assembly of container 11, rotation gear 33 and rotation shaft 34 of rotation mechanism 15, and second rotation mechanism 61) is mounted, eccentrically with respect to the sun axis (revolution axis 12), so as to be rotatable about a second planetary axis of rotation (rotation axis 60) together with the first grinding vessel receiving device (container fixing member 64) and the grinding vessel (container 11); wherein a drive ([0085] lns 1-3: the rotation actuator is interpreted as the drive) is included for rotatably driving the first grinding vessel receiving device together with the grinding vessel about the second planetary axis of rotation at a second planetary rotational speed ([0089] lns 1-4); and wherein during operation the first grinding vessel receiving device together with the grinding vessel revolves around the sun axis on the planetary orbit ([0033] lns 4-6), and at the same time the first grinding vessel receiving device together with the grinding vessel rotates about the first and about the second planetary axis of rotation ([0089] lns 1-3: container 11 is rotated simultaneously about rotation axes 14 and 60).
Regarding Claim 15, Gouko discloses (Figure 11) the first and second planetary axis of rotation (rotation axes 14 and 60) do not extend in parallel (clearly seen in figure).
Regarding Claim 16, Gouko discloses (Figure 11) the first and second planetary axis of rotation (rotation axes 14 and 60) extend perpendicularly to one another (clearly seen in figure).
Regarding Claim 17, Gouko discloses (Figure 11) the second planetary axis of rotation (rotation axis 60) extends so as to be in parallel with and radially offset from the sun axis (revolution axis 12; [0086] lns 1-6: rotation shaft 62, through which rotation axis 60 passes, rotates about rotation axis 14; when the assembly has rotated 90 degrees about rotation axis 14 relative to the orientation shown in Figure 11, rotation axis 60 will extend in parallel with revolution axis 60 and be radially offset therefrom).
Regarding Claim 18, Gouko discloses (Figure 11) the first and second planetary axis of rotation (rotation axes 14 and 60) intersect at a point located eccentrically with respect to the sun axis (revolution axis 12), within the first planetary grinding station (clearly seen in figure).
Regarding Claim 19, Gouko discloses (Figure 11) the first grinding vessel receiving device (container fixing member 64) is suspended in a gimballed manner on the carrier device ([0086] lns 5-6, [0087] lns 3-4: container fixing member 64, which is carried by rotation shaft support member 63, is suspended such that it is rotatable about two orthogonal axes and is thus suspended in a gimballed manner).
Regarding Claim 20, Gouko discloses (Figure 11) the first grinding vessel receiving device (container fixing member 64) is mounted in a gimballed manner on the carrier device (revolution arm 24, see Figure 1) so as to be rotatable about the first and second planetary axis of rotation (rotation axes 14 and 60; [0086] lns 5-6, [0087] lns 3-4: container fixing member 64, which is carried by rotation shaft support member 63, is suspended such that it is rotatable about two orthogonal axes and is thus suspended in a gimballed manner), wherein the gimballed mounting of the first grinding vessel receiving device is arranged eccentrically with respect to the sun axis (revolution axis 12; clearly seen in figure), and wherein the first grinding vessel receiving device together with the grinding vessel (container 11) is driven so as to rotate about the first and about the second planetary axis of rotation ([0089] lns 4-5).
Regarding Claim 21, Gouko discloses (Figure 11) the first planetary grinding station (assembly of container 11, rotation gear 33 and rotation shaft 34 of rotation mechanism 15, and second rotation mechanism 61) comprises a retaining device (assembly of rotation shaft support member 63 and rotation shaft 34) having at least one first pivot bearing (roller bearings for rotation shaft 34 shown in Figure 1) for the grinding vessel receiving device (container fixing member 64), and wherein the first pivot bearing defines the first planetary axis of rotation (rotation axis 14), wherein the first planetary grinding station comprises a second planetary shaft (rotation shaft 62), and the carrier device comprises a second pivot bearing (coupling of rotation shaft 62 and rotation shaft support member 63) in the region of the first planetary grinding station, which pivot bearing defines the second planetary axis of rotation (rotation axis 60), in such a way that the first planetary grinding station is rotatably mounted in the carrier device by means of the second planetary shaft ([0087] lns 1-7), concentrically with respect to the second planetary axis of rotation, and such that the grinding vessel receiving device is mounted in a gimballed manner on the carrier device ([0086] lns 5-6, [0087] lns 3-4: container fixing member 64, which is carried by rotation shaft support member 63, is suspended such that it is rotatable about two orthogonal axes and is thus suspended in a gimballed manner), eccentrically with respect to the sun axis (revolution axis 12), and, during operation, is driven so as to rotate about the first and the second planetary axis of rotation ([0089] lns 4-5).
Regarding Claim 22, Gouko discloses (Figures 1 and 11) a first planetary synchronous drive (rotation mechanism 15) for the grinding vessel receiving device (container fixing member 64), wherein the first planetary synchronous drive drives the rotation of the grinding vessel receiving device about the first planetary axis of rotation (rotation axis 14), synchronously to the rotation of the carrier device (para. [0052]-[0053] describes synchronous rotation of first planetary grinding station in embodiment of Figure 1, which is analogous to the first planetary grinding station in the embodiment of Figure 11, with the revolution arm 24).
Examiner note: regarding the limitation “a second planetary synchronous drive…drives the rotation of the grinding vessel receiving device about the second planetary axis of rotation, synchronously to the rotation of the carrier device”, the inclusion of the phrase “and/or” indicates that this feature is not necessary to meet all the requirements of the claim.
Regarding Claim 24, Gouko discloses (Figure 11) the rotational speed ratio between the rotation of the first grinding vessel receiving device (container fixing member 64), together with the grinding vessel (container 11), about the first planetary axis of rotation (rotation axis 14), and about the second planetary axis of rotation (rotation axis 60), is, according to amount, in the range between 10:1 and 0.1:1 ([0089] lns 1-5: the rotational speed ratio is 1:1, which is within the claimed range).
Examiner note: regarding the limitation “the relative rotational speed ratio between the rotation of the first grinding vessel receiving device, together with the grinding vessel, about the second planetary axis of rotation, and the rotation of the carrier device about the sun axis, is, according to amount, in the range between 25:1 and 0.5:1”, the inclusion of the phrase “and/or” indicates that this feature is not necessary to meet all the requirements of the claim.
Regarding Claim 25, Gouko discloses (Figures 1-2 and 11) a second, third, fourth and/or further planetary grinding stations (assembly of container 11, rotation gear 33 and rotation shaft 34 of rotation mechanism 15, and second rotation mechanism 61; [0101] lns 1-5: the depicted embodiments each have two planetary grinding stations, but more than two may also be used), which are arranged on the planetary orbit and are constructed identically to the first planetary grinding station (clearly seen in Figures 1-2) and are in each case driven so as to rotate about their own first and/or second planetary axis of rotation (rotation axes 14 and 60).
Regarding Claim 26, Gouko discloses (Figures 11-13) the planetary mill (centrifugal ball mill 10) has at least the following structural and dynamic parameters: sun radius, defined as the eccentric offset of the center point of the first planetary grinding station with respect to the sun axis (distance between revolution axis 12 and rotation axis 60); planetary internal radius, defined as the internal radius of the interior for pouring in the material to be ground and the grinding media (distance between container center axis 11a and inner periphery face 11b of container 11); ratio of the sun radius to the planetary internal radius (ratio of two aforementioned distances); sun rotational speed ([0051] lns 2-6: revolution arm 24 is driven to rotate about revolution axis 12, i.e. the sun axis, at a given sun rotational speed); first planetary rotational speed ([0054] lns 1-5); second planetary rotational speed ([0089] lns 4-5: rotation speed about rotation axis 60 is interpreted as the second planetary rotational speed); ratio of the first planetary rotational speed to the sun rotational speed (ratio of aforementioned sun rotational speed with rotational speed about rotation axis 14); and/or ratio of the second planetary rotational speed to the sun rotational speed (ratio of aforementioned sun rotational speed with rotational speed about rotation axis 60), wherein the design and dynamic parameters of the planetary mill are selected such that, during operation, the material to be ground and provided grinding media (grinding balls 50) sometimes detach from the inside wall of the grinding vessel (inner periphery face 11b, top 11c, and bottom 11d), move through the interior of the grinding vessel, and strike against the inside wall of the grinding vessel again (para. [0092]-[0093] discuss the movement trajectory of the grinding balls 50).
Regarding Claim 27, Gouko discloses (Figures 11-13) the eccentric offset of the first planetary grinding station (assembly of container 11, rotation gear 33 and rotation shaft 34 of rotation mechanism 15, and second rotation mechanism 61) with respect to the sun axis (revolution axis 12) defines a sun radius between the sun axis and the center point of the planetary grinding station (distance between revolution axis 12 and rotation axis 60), and the grinding vessel (container 11) defines an interior for pouring in the material to be ground and the grinding media (crushing balls 50), and the interior defines a planetary internal radius (distance between container center axis 11a and inner periphery face 11b). Gouko does not explicitly disclose a ratio of the planetary internal radius to the sun radius, but based on the provided figures (in particular Figures 1 and 2, which depict the entire centrifugal ball mill 10), the ratio of the two radii appears to be approximately 1:5.5, which falls within the claimed range of 1:0.5 to 1:10, so this limitation of the claim is met.
Regarding Claim 28, Gouko discloses (Figures 11-13) the grinding vessel (container 11) comprises a cylindrical, spherical or elliptical interior for pouring in the material to be ground and the grinding media (grinding balls 50), and/or has a cylindrical external shape ([0048] lns 3-4: container 11 has a cylindrical external shape and a cylindrical interior).
Examiner note: regarding the limitation “the grinding vessel comprises a grinding cup and a grinding cup lid which is detachable from the grinding cup”, the inclusion of the phrase “and/or” indicates that this feature is not necessary to meet all the requirements of the claim.
Regarding Claim 30, Gouko discloses (Figure 11) the first grinding station (assembly of container 11, rotation gear 33 and rotation shaft 34 of rotation mechanism 15, and second rotation mechanism 61) comprises a retaining device (rotation shaft support member 63) and a first planetary shaft (rotation shaft 34), on which the first grinding vessel receiving device (container fixing member 64) is fastened (via rotation shaft 62) and by means of which the first grinding vessel receiving device is rotatably mounted in the retaining device ([0086] lns 3-6), wherein the grinding vessel (container 11) can be inserted into the grinding vessel receiving device and be braced therein ([0087] lns 5-7), and wherein the first grinding vessel receiving device together with the grinding vessel braced therein can rotate in the retaining device ([0033] lns 6-8, [0086] lns 5-6, [0087] lns 4-6: container 11 is braced within container fixing member 64, which is mounted within rotation shaft support member 63, and the entire assembly rotates about rotation axis 14), driven at a first planetary rotational speed ([0054] lns 1-5).
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 4, 29, and 31-35 are rejected under 35 U.S.C. 103 as being unpatentable over Gouko as applied to Claim 1 above, and further in view of Bund et al., hereinafter Bund (DE 102010044254). For text citations of Bund, refer to the machine translation provided as Non-Patent Literature.
Regarding Claim 4, Gouko discloses (Figure 1) the rotation of the carrier device (revolution arm 24) about the sun axis (revolution axis 12) is driven by means of a drive motor (revolution actuator 20), but does not disclose a sun belt drive; the revolution actuator 20 drives the rotation of revolution arm 24 via a set of revolution gears 21/22. In the same field of endeavor, Bund teaches (Figures 1-2) a planetary mill for comminuting material to be ground, comprising a sun axis (center axis 10) and a carrier device (carrier device 2) which is mounted so as to be rotatable about the sun axis ([0026] ln 4), and a drive (drive means 4) for rotatably driving the carrier device about the sun axis at a sun rotational speed, comprising a sun belt drive (V-belt 41 and V-belt pulley 42) for driving the rotation of the carrier device about the sun axis by means of a drive motor (motor 40). This sun belt drive performs the same function as the gear configuration of Gouko, so it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the planetary mill disclosed by Gouko such that it comprises a sun belt drive for driving the rotation of the carrier device about the sun axis by means of a drive motor, as taught by Bund, by performing a simple substitution of the sun belt drive of Bund for the gear drive configuration of Gouko, in order to perform the same function of driving the rotation of the carrier device about the sun axis.
Regarding Claim 29, Gouko discloses (Figure 11) different grinding vessels (container 11) can be exchangeably inserted into the first grinding vessel receiving device (container fixing member 64; [0087] lns 5-7: container 11 is inserted into container fixing member 64, implying that container fixing member 64 is capable of receiving different containers 11 exchangeably), but is silent to the structural details of the grinding vessels and grinding vessel receiving device beyond their respective cylindrical shapes. In the same field of endeavor, Bund teaches (Figures 3-7) a planetary ball mill comprising a first grinding vessel receiving device (receiving device 3) for at least one grinding vessel (grinding cups 5) that can be filled with material to be ground and grinding media ([0035] lns 1-2), wherein the grinding vessels comprise a grinding cup (inner/outer shells 51/52) and a grinding cup lid (lid 53) that can be detached from the grinding cup in order to be able to pour the material to be ground into the grinding cup and remove it therefrom ([0035] lns 1-2: lid 53 is closed after the grinding cup is filled, therefore it must be open, i.e. detached from the inner/outer shells 51/52, while the grinding cup is being filled), and wherein the first grinding vessel receiving device comprises a bracing device (holding device 6 having spring rod 60 and pressure body 61), in order to reliably brace the grinding cup, closed by the grinding cup lid, in the first grinding vessel receiving device for the grinding process ([0029] lns 10-12). The bracing device helps hold the grinding cup in place and thereby prevent damage thereto during operation ([0036] lns 1-7). Accordingly, and as the grinding vessel structure is known from the art, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the planetary mill disclosed by Gouko such that the grinding vessels comprise a grinding cup and a grinding cup lid that can be detached from the grinding cup in order to be able to pour the material to be ground into the grinding cup and remove it therefrom, and the first grinding vessel receiving device comprises a bracing device, in order to reliably brace the grinding cup, closed by the grinding cup lid, in the first grinding vessel receiving device for the grinding process, as taught by Bund, in order to prevent damage to the grinding vessel due to vibrations during operation.
Regarding Claim 31, Gouko does not disclose the first grinding vessel receiving device comprising a clamping cage. In the same field of endeavor, Bund teaches (Figures 3-7) a planetary ball mill comprising a first grinding vessel receiving device (receiving device 3) for at least one grinding vessel (grinding cups 5) that can be filled with material to be ground and grinding media ([0035] lns 1-2), wherein the first grinding vessel receiving device comprises a clamping cage (assembly of clamping drive 7 and receiving device 3) in which the grinding vessel can be braced ([0031] lns 1-2), wherein the clamping cage comprises the following: a cage lower part (receiving chamber 35 of receiving device 3), configured for insertion of the grinding vessel ([0029] ln 6), wherein the cage lower part comprises an annular portion (upper bearing ring 31), a shell portion (connecting webs 33) that is connected to the annular portion and extends axially from the annular portion, and a cage bottom (lower base ring 32) which delimits the shell portion at the bottom; a cage lid part (lever 73) for closing the clamping cage (clamping position shown in Figure 7), wherein the grinding vessel can be inserted into the clamping cage and removed from the clamping cage when the clamping cage is open (release position shown in Figures 5 and 6); and a bracing device (holding device 6 having spring rod 60 and pressure body 61) for bracing the grinding vessel in the clamping cage when the clamping cage is closed ([0031] lns 1-2: clamping drive 7 tensions spring rod 60 of holding device 6 to brace the grinding cup 5 in the receiving device 3 when the lever 73 is in the clamping position shown in Figure 7). The configuration of the clamping cage with the bracing device helps hold the grinding cup in place and thereby prevent damage thereto during operation ([0036] lns 1-7). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the planetary mill disclosed by Gouko such that the first grinding vessel receiving device comprises a clamping cage in which the grinding vessel can be braced, wherein the clamping cage comprises the following: a cage lower part, configured for insertion of the grinding vessel, wherein the cage lower part comprises an annular portion, a shell portion that is connected to the annular portion and extends axially from the annular portion, and a cage bottom which delimits the shell portion at the bottom; a cage lid part for closing the clamping cage, wherein the grinding vessel can be inserted into the clamping cage and removed from the clamping cage when the clamping cage is open; and a bracing device for bracing the grinding vessel in the clamping cage when the clamping cage is closed, as taught by Bund, in order to prevent damage to the grinding vessel due to vibrations during operation.
Regarding Claim 32, with reference to the combination of Gouko and Bund of Claim 31, Bund teaches (Figures 6-7) the cage lid part (lever 73) can be detachably fastened to the cage lower part (receiving chamber 35 of receiving device 3; [0032] lns 8-13: lever 73 is fastened to receiving device 3 via locking device 8, and is detachable therefrom to assume the release position).
Regarding Claim 33, with reference to the combination of Gouko and Bund of Claim 31, Bund teaches (Figures 4-7) the cage lid part (lever 73) and the cage lower part (receiving chamber 35 of receiving device 3) comprise a closure (locking device 8), and the cage lid part is fastened to the cage lower part by the closure during operation of the planetary mill ([0032] lns 11-13).
Regarding Claim 34, Gouko is silent to the structural details of the grinding vessel beyond its cylindrical shape. Bund teaches (Figures 5-7) the grinding vessel (grinding cup 5) comprises a grinding cup (inner/outer shells 51/52) having a grinding cup axis (planetary axis 30, see Figure 1), and a grinding cup lid (lid 53) which can be detached from the grinding cup, in order to be able to pour material to be ground into the grinding cup and remove it therefrom ([0035] lns 1-2: lid 53 is closed after the grinding cup is filled, therefore it must be open, i.e. detached from the inner/outer shells 51/52, while the grinding cup is being filled), and wherein the grinding cup lid can be braced axially against the grinding cup by means of the bracing device (holding device 6 having spring rod 60 and pressure body 61), when the grinding vessel is inserted into the clamping cage ([0029] lns 10-12, [0036] lns 1-5). This is a known configuration for a grinding vessel, and has the advantage of resisting vibrations during operation to avoid damage to the grinding vessel ([0036] lns 1-6). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the grinding vessel of the planetary mill disclosed by Gouko such that it comprises a grinding cup having a grinding cup axis, and a grinding cup lid which can be detached from the grinding cup, in order to be able to pour material to be ground into the grinding cup and remove it therefrom, and wherein the grinding cup lid can be braced axially against the grinding cup by means of the bracing device, when the grinding vessel is inserted into the clamping cage, as taught by Bund, as this is a known configuration for a grinding vessel for a planetary mill which is able to resist vibrations and consequent damage during operation.
Regarding Claim 35, with reference to the combination of Gouko and Bund of Claim 29, Bund teaches (Figures 5-7) the bracing device (holding device 6 having spring rod 60 and pressure body 61) exerts a clamping force on the grinding vessel, which force acts perpendicularly to the first planetary shaft (shaft extending through belt pulley 45, shown in Figure 3).
Claims 6, 11-12, 14, and 23 are rejected under 35 U.S.C. 103 as being unpatentable over Gouko as applied to Claims 1, 10, and 22, respectively, above, and further in view of Baer et al., hereinafter Baer (DE 102006018325). For text citations of Baer, refer to the machine translation provided as Non-Patent Literature.
Regarding Claim 6, Gouko does not disclose that the first planetary synchronous drive is configured as a toothed belt drive; rather, the disclosed first planetary synchronous drive uses gears 31/32/33 to drive the rotation of the grinding vessel receiving device synchronously to the rotation of the carrier device, of which gear 33 is perpendicular to gears 31/32 to drive rotation of the grinding vessel receiving device about rotation axis 14, which is perpendicular to revolution axis 12 (see para. [0052]-[0053]). In the same field of endeavor, Baer teaches (Figures 3-7) a planetary mill ([0001] lns 1-2) comprising a sun axis (central axis 24) and a carrier device (carrier device 2) which is mounted so as to be rotatable about the sun axis ([0054] ln 3), a first axis of rotation (axis through threaded spindle 74) perpendicular to the sun axis about which an element (threaded spindle 74) is driven to rotate ([0055] ln 7), and a first synchronous drive (drive 6) between the carrier device and the element, wherein the first synchronous drive drives the rotation of the element about the first axis of rotation synchronously to the rotation of the carrier device ([0055] lns 4-7: as carrier device 2 rotates, drive 6 causes spindle 74 to rotate as well), wherein the first synchronous drive is configured as a first toothed belt drive ([0053] lns 1-13) and comprises a drive toothed belt pulley (toothed belt pulley 65) and an output toothed belt pulley (pulley 73), wherein the drive toothed belt pulley is rigidly connected to a sun axis end (upper end 64 of drive shaft 61 which extends through center of central axis 24), wherein during rotation of the carrier device, the output toothed belt pulley is carried along by the carrier device on a planetary orbit around the sun axis and is thereby caused to rotate by the first toothed belt drive ([0055] lns 4-7: by nature of pulley 73 being arranged on carrier device 2 eccentric to drive shaft 61, as seen in Figure 7, as carrier device 2 rotates, pulley 73 will be carried in a planetary orbit around drive shaft 61/central axis 24, and the relative rotation between drive shaft 61 with pulley 65 attached thereto and carrier device 2 causes toothed belt 66 to move and therefore rotate pulley 73). This synchronous drive performs the same function as the first planetary synchronous drive disclosed by Gouko, i.e. driving an element to rotate about an axis perpendicular to the sun axis synchronously with the rotation of the carrier device. Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the first planetary synchronous drive in the planetary mill disclosed by Gouko such that it is configured as a first planetary toothed belt drive and comprises a drive toothed belt pulley and an output toothed belt pulley, wherein the drive toothed belt pulley is rigidly connected to a sun axis end, wherein during rotation of the carrier device, the output toothed belt pulley is carried along by the carrier device on a planetary orbit around the sun axis and is thereby caused to rotate by the first planetary toothed belt drive, as taught by Baer, as this is a known configuration for a synchronous drive in a planetary mill.
Regarding Claim 11, Gouko does not disclose that the drive for rotatably driving the first grinding vessel receiving device about the first planetary axis of rotation is configured as a toothed belt drive; rather, the disclosed drive uses gears 31/32/33, of which gear 33 is perpendicular to gears 31/32, to drive the rotation of the grinding vessel receiving device about rotation axis 14, which is perpendicular to revolution axis 12 (see para. [0052]-[0053]). In the same field of endeavor, Baer teaches (Figures 3-7) a planetary mill ([0001] lns 1-2) comprising a sun axis (central axis 24), a first axis of rotation (axis through threaded spindle 74) perpendicular to the sun axis about which an element (threaded spindle 74) is driven to rotate ([0055] ln 7), and a drive (drive 6) for rotatably driving the element about the first axis of rotation at a first rotational speed ([0055] lns 4-7), wherein the drive for rotatably driving the element about the first axis of rotation at a first rotational speed is configured as a first toothed belt drive ([0053] lns 1-13). This toothed belt drive performs the same function as the gear drive configuration disclosed by Gouko, i.e. driving an element to rotate about an axis perpendicular to the sun axis. Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the drive for rotatably driving the first grinding vessel receiving device together with the grinding vessel about the first planetary axis of rotation at a first planetary rotational speed in the planetary mill disclosed by Gouko such that it is configured as a first toothed belt drive, as taught by Baer, as this is a known configuration for driving rotation of a grinding vessel in a planetary mill.
Examiner note: regarding the limitation “the drive for rotatably driving the first grinding vessel receiving device together with the grinding vessel about the second planetary axis of rotation at a second planetary rotational speed is configured as a second toothed belt drive”, the inclusion of the phrase “and/or” indicates that this feature is not necessary to meet all the requirements of the claim.
Regarding Claim 12, with reference to the combination of Gouko and Baer of Claim 11, Baer teaches (Figures 3-7) the first toothed belt drive (drive 6) comprises at least one deflection roller (deflection pulleys 71/72) and is configured as a restricted toothed belt drive (toothed belt 66).
Regarding Claim 14, with reference to the combination of Gouko and Baer of Claim 11, Baer teaches (Figures 3-7) the first toothed belt drive (drive 6) comprises a horizontal drive toothed belt pulley (toothed belt pulley 65), a vertical output toothed belt pulley (pulley 73), and a restricted toothed belt (toothed belt 66).
Regarding Claim 23, Gouko does not disclose that the first planetary synchronous drive is configured as a toothed belt drive; rather, the disclosed first planetary synchronous drive uses gears 31/32/33 to drive the rotation of the grinding vessel receiving device synchronously to the rotation of the carrier device, of which gear 33 is perpendicular to gears 31/32 to drive rotation of the grinding vessel receiving device about rotation axis 14, which is perpendicular to revolution axis 12 (see para. [0052]-[0053]). In the same field of endeavor, Baer teaches (Figures 3-7) a planetary mill ([0001] lns 1-2) comprising a sun axis (central axis 24) and a carrier device (carrier device 2) which is mounted so as to be rotatable about the sun axis ([0054] ln 3), a first axis of rotation (axis through threaded spindle 74) perpendicular to the sun axis about which an element (threaded spindle 74) is driven to rotate ([0055] ln 7), and a first synchronous drive (drive 6) between the carrier device and the element, wherein the first synchronous drive drives the rotation of the element about the first axis of rotation synchronously to the rotation of the carrier device ([0055] lns 4-7: as carrier device 2 rotates, drive 6 causes spindle 74 to rotate as well), wherein the first synchronous drive is configured as a first toothed belt drive ([0053] lns 1-13) and comprises a drive toothed belt pulley (toothed belt pulley 65) and an output toothed belt pulley (pulley 73), wherein the drive toothed belt pulley is rigidly connected to the carrier device ([0053] lns 9-11), wherein during rotation of the element by means of the first toothed belt drive the rotation of the element about the first axis of rotation is driven ([0055] lns 4-7: threaded spindle 74 is driven to rotate by toothed belt 66 of drive 6). This synchronous drive performs the same function as the first planetary synchronous drive disclosed by Gouko, i.e. driving an element to rotate about an axis perpendicular to the sun axis synchronously with the rotation of the carrier device. Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the first planetary synchronous drive in the planetary mill disclosed by Gouko such that it is configured as a first planetary toothed belt drive and comprises a drive toothed belt pulley and an output toothed belt pulley, wherein the drive toothed belt pulley is rigidly connected to the carrier device, wherein during rotation of the first planetary grinding station by means of the first planetary toothed belt drive the rotation of the grinding vessel receiving device together with the grinding vessel about the first planetary axis of rotation is driven, as taught by Baer, as this is a known configuration for a synchronous drive in a planetary mill.
Examiner note: regarding the limitation “wherein the second planetary synchronous drive is configured as a second planetary toothed belt drive…and as a result the first planetary grinding station is caused to rotate by the second planetary toothed belt drive”, the inclusion of the phrase “and/or” indicates that this feature is not necessary to meet all the requirements of the claim.
Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Gouko.
Regarding Claim 7, Gouko is silent to the relative rotational speed ratio between the rotation of the first grinding vessel receiving device, together with the grinding vessel, about the first planetary axis of rotation, and the rotation of the carrier device about the sun axis, but does disclose that the rotational speed of the first grinding vessel receiving device (container fixing member 64) with the grinding vessel (container 11) about the first planetary axis of rotation (rotation axis 14) can be changed via the drive (rotation actuator 30; [0054] lns 1-5), and that controlling the rotation in that way allows the trajectory of crushing balls 50 within container 11 to be adjusted to accommodate different materials to be crushed or target crushing parameters ([0066] lns 1-11). Accordingly, as the Applicant has not set forth any criticality to the selection of this particular range of relative rotational speed ratios that results in an unexpected benefit, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to design the planetary mill disclosed by Gouko such that the relative rotational speed ratio between the rotation of the first grinding vessel receiving device, together with the grinding vessel, about the first planetary axis of rotation, and the rotation of the carrier device about the sun axis is, according to amount, in the range between 10:1 and 0.5:1, because such selection or determination would be the result of routine mechanical optimization and does not in itself warrant patentability, as one would arrive at such optimization through routine engineering practices.
Allowable Subject Matter
Claim 13 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter: prior art fails to teach, alone or in combination, a planetary mill comprising a first planetary grinding station having a first grinding vessel receiving device for at least one grinding vessel that is mounted so as to be rotatable about a first planetary axis of rotation and a second planetary axis of rotation, a drive for rotatably driving the first grinding vessel receiving device together with the grinding vessel about the first planetary axis of rotation at a first planetary rotational speed, wherein the drive is configured as a first toothed belt drive, wherein the first toothed belt drive comprises a horizontal drive toothed belt pulley which is arranged coaxially to the second planetary axis of rotation and is connected to the carrier device, together with the other limitations of the claim. In the combination of Gouko and Baer, the horizontal drive pulley (Baer toothed belt pulley 65) is arranged coaxially to the sun axis (Baer central axis 24/Gouko revolution axis 12), and could not be modified to be coaxial to the second planetary axis of rotation (Gouko rotation axis 60), as the drive 6 of Baer would not be able to function without pulley 65 coaxial to the sun axis.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure:
King et al. (US 2023/0011579) discloses a planetary ball mill comprising planetary grinding stations equipped with a camping cage and bracing device for holding the grinding vessels during operation.
