Claims 19 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Haimer ‘059 (U.S. Patent 8,963,059) in view of Shigefuji, (U.S. Patent 6,163,734), Haimer ‘386 (U.S. Patent Application Publication 2008/ 0277386, herein after “Haimer ‘386”) and Kelch (U.S. Patent Application Publication 2001/ 0054471).
Regarding claim 19, Haimer ‘059 discloses an induction coil unit ( Haimer ‘059, Abstract, “a device for inductively clamping and unclamping a tool shaft of a tool”) for heating a freely-terminating sleeve portion of a tool holder having a receiving opening (Haimer, receiving bore hole 5, fig. 1, column 2 line 24) formed therein for a shank of a rotary tool (shaft 9) , in which the freely-terminating sleeve portion holds the shank of the rotary tool seated in the receiving opening in a press fit and releases the rotary tool upon heating (Haimer ‘059, column 6 lines 29-36; “The exterior diameter of the shaft 9 is then slightly larger than the free nominal diameter of the receiver bore hole 5, so that the shaft 9, when it is inserted in the bore hole 5, is supported in the clamping sleeve 3 through a friction locking press fit for transferring the operating torque. In order to be able to insert the tool shaft 9 into the tool holder 1 and in order to be able to also remove it, the clamping sleeve 3 is expanded through heating.), the induction coil unit comprising:
a holding apparatus (clamping sleeve 3, column 6 lines 42 et seq.) configured for holding the tool holder during a heating operation;
a coil configuration (Haimer ‘059, “induction coil” 13 and “coil units” 14a and 14b which together make 15, within “coils housings” 17a, and 17b, figs. 1 and 2) enclosing the freely-terminating sleeve portion of the tool holder during the heating operation, said coil configuration having an adjustable geometry (column 6 line 63 – column 7 line 3, adjustment of the two coil units 14a a, 14b is facilitated along the rotation axis 7) ;
a magnetic flux concentrator configuration (sleeve shaped concentrators, 19a and 19b, concentrator ring 21) disposed on a side of said coil configuration adjacent a free end of the freely-terminating sleeve portion, said magnetic flux concentrator configuration being disposed at least near the free end of the freely-terminating sleeve portion of the tool holder and being made of a magnetic material that is substantially electrically non-conductive (column 7 lines 21-22 “[concentrators are] made from magnetically conductive but electrically nonconductive material, like e.g., an oxide ceramic material, in particular ferrite, see Haimer ‘414, U.S. Patent 9,278,414, Column 7 lines 48-50 which teaches that “concentrator elements [] are entirely comprised of magnetically soft, substantially electrically nonconductive material, e.g. ferrite”);
a memory storing data (Haimer ‘059, Column 11 line 62 “[T]he respective geometry and shrink parameters with respect to different shrink fit chucks can either be read in from an external data source or through a suitable scanner which reads from a respective data carrier on the shrink fit chuck and thus facilitates the respective adjustment and control of the two motors”) of a type of tool holder that is held by said holding apparatus, based on the coding obtained from said detector, and storing data related to at least one property of the tool holder held by said holding apparatus, the at least one property being selected from the group consisting of an outer dimension, a wall thickness, and an axial extension of the tool holder (Haimer ‘058, column 11 line 58, “As a consequence of the separate adjustability of the diameter and the length of the distance coil of the coil units, simple controllability is provided for fully operated operations.);
a controller (Haimer, ‘059, column 5 lines 30-51, “automated operations…can be configured with a data carrier… associated through digital image processing, with laser scanners, distance sensors and similar… The power supply of the drive unit can be turned off and on through a control signal together with the shrink electronics”) connected to said memory and, being in data communication, respectively, with said memory to obtain the data relating to the at least one property of the tool holder, and with said at least one actuator to direct an adaptation of the at least one operating parameter, said controller being configured to direct the adaptation of the at least one operating parameter by adjusting the geometry of said coil configuration based on the at least one property of the tool holder detected by said at least one detector (Haimer ‘059, column 10 lines 47-52, “The slanted support of the slides and thus the slanted position of the concentrator elements received on the inside of the slides can result in that the concentrator elements are not only moved radially in a direction towards the rotation axis 7, but also with an additional axial component in a direction towards the clamping sleeve 3 into their operating position”).
Haimer ‘059 does not disclose “at least one detector for automatically detecting a coding furnished on the tool holder, said coding being selected from the group consisting of an optical coding, a textural marking, an RFID chip, and a mechanical marking; at least one actuator for adapting at least one operating parameter of the heating operation, said actuator being configured to adjust the geometry of said coil configuration and to adjust an AC voltage and /or frequency of the AC voltage of an electrical supply to said coil configuration, and to adjust a positioning of said coil configuration by way of a movable stop for said coil configuration”.
However, Shigefuji teaches a coding furnished on the tool holder, said coding being selected from the group consisting of an optical coding, a textural marking, an RFID chip, and a mechanical marking (Shigefuji, column 1, lines 34-55, “ During the operation of the press, desired upper and lower tools are selected and taken out from the magazine on the basis of such tool-pair information, so that the tools are changed with old tools on the punch press. The tool-pair information includes tool shape information, tool size information and tool clearance information. The tool information includes a tool manufacturing number and a tool manufacturing date. Such information may be represented by bar codes that is provided on the surface of the tools to be read by a bar code scanner.). Thus, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention, to modify Haimer ‘059 with the teachings of Shigefuji, to have optical markings for inserting the tool into the holder and knowing its identity, and thus knowing the required insertion configuration and parameters for quick changes, and this recognizing that Haimer ‘058 is very interested in determining the geometry and configuration of its tool and chuck, and it does this with scanners of its own, so this would be a beneficial modification (Haimer ‘059, column 12 lines 1-7, “geometric data of the chuck”; column 5 lines 30-35, “the respective geometry data of a chuck or a clamping sleeve of a tool holder are determined automatically for a fully automated shrinking process, wherein the chuck or the tool holder can be configured with a respective data carrier.” Wherein, “outer dimension, a wall thickness, and an axial extension” are all “geometry data” of the tool holder or the chuck) having the tool be identified quickly and easily with a code.
And while Haimer ‘059 in view of Shigefuji teaches the above limitation, it still does not teach at least one actuator for adapting at least one operating parameter of the heating operation, said actuator being configured to adjust the geometry of said coil configuration and to adjust an AC voltage and /or frequency of the AC voltage of an electrical supply to said coil configuration, and to adjust a positioning of said coil configuration by way of a movable stop for said coil configuration”.
However, Haimer ‘386 teaches at least one actuator (Haimer ‘386, AC Generator, 19a) for adapting at least one operating parameter of the heating operation (Haimer ‘386, ¶0054), said actuator being configured to adjust the geometry of said coil configuration and to adjust an AC voltage and /or frequency of the AC voltage of an electrical supply to said coil configuration (Haimer ‘386, at least claim 22.” the coil units are connected to an AC generator, whose current and/or power on duration and/or voltage is adjustable, and which controls at least one positioning drive depending on the setting”.).
Thus, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention, to modify Haimer ‘059 in view of Shigefuji with the teachings of Haimer ‘386, to have at least one operating parameter be adjusted and adjusting the AC voltage and/or the frequency, to adjust the coil, in order to cause effective holding of the tool, depending on geometry and/or size and or desired grip of the tool.
And while Haimer ‘059 in view of Shigefuji and Haimer ‘386 teaches all the limitations above, they still do not teach “to adjust a positioning of said coil configuration by way of a movable stop for said coil configuration”. However, a movable and adjustable stop is a conventional method of adjusting coils, as taught in Kelch in his method for shrink an thermal clamping. Thus, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention, to modify Haimer ‘059 in view of Shigefuji and Haimer ‘386 with the teachings of Kelch, to have a movable stop for adjusting the induction coil, in order to ensure that the movement of the coil is accurate and produces an optimum electric field for optimum coupling allowing for proper clamping.
Regarding claim 20, Haimer ‘059 in view of Shigefuji, Haimer ‘386 and Kelch teaches all the limitations of claim 19, as above, and further teaches wherein said actuator is adapted to adjust a positioning of said magnetic flux concentrator configuration in a tool holder's axial and/or radial direction during the heating operation (Haimer ‘059, column 5 lines 35-40, “the coil can be automatically adjusted”; column 12 lines 3-6; Of particular note is that the concentrators are also movable in order to best heat up the device in order to achieve shrink locking; Abstract, “concentrator elements are movable relative to the rotational axis with a radial and an axial component; Kelch, in combination, also allows for movement in.).
Claim 21 is rejected under 35 U.S.C. 103 as being obvious over Haimer ‘059 (U.S. Patent 8,963,059) and in view of Shigefuji, (U.S. Patent 6,163,734) Haimer ‘386 (U.S. Patent Application Publication 2008/ 0277386) and Kelch (U.S. Patent Application Publication 2001/ 0054471), and further in view of Pfau (U.S. Patent Application 2006/ 0163245).
Regarding claim 21, Haimer '059 in view of Shigefuji, Haimer '386 and Kelch teaches all the limitations of claim 19, as above, but does not further teach an apparatus comprising: at least one suction device for vapor produced during heating; and/or a sealing element for cooling media, said actuator is adapted to adjust a positioning of said at least one suction device and/or said at least one sealing - 20 -HAI-0094 element for cooling media in a tool holder's axial and/or radial direction during the heating operation. However, Pfau teaches a suction device to get rid of vapor or gases produced by the holder during the heating process that arise from the holder (Pfau, Abstract, gas suction device for evacuating gases, fig. 1). The advantage would be to ensure that the workspace remains clean and not offensive while inserting the tools, thus it would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify Haimer ‘059 and Haimer ‘386 with Pfau, to have a suction device to capture the escaping gases to make for a more pleasant working environment (Pfau, ¶0036-0038, prevents gases “emerg[ing] into surroundings”).
Claims 22 and 24 are rejected under 35 U.S.C. 103 as being obvious over Haimer ‘059 (U.S. Patent 8,963,059) in view of Shigefuji (WIPO Patent Publication WO2004091847A2, attached, hereinafter “Shigefuji”), Haimer ‘386 (U.S. Patent Application Publication 2008/ 0277386) and Kelch (U.S. Patent Application Publication 2001/ 0054471) and further in view of Haimer ‘069 (U.S. Patent Application Publication 2016/ 0113069) and as evidenced by Pankratz (U.S. Patent Application Publication 2015/ 0041455).
Regarding claim 22, Haimer ‘059 in view of Shigefuji and Haimer ‘386 teaches all the limitations of claim 19, as above, and but does not further teach explicitly: said coil configuration has a switchable and/or reversible-polarity winding region. However, Haimer ‘069 teaches that “said coil configuration has a reversible-polarity winding region”, meaning that the windings support polarity reversal (Haimer ‘069 ¶0099, “the coils are all wound in the same sense with respect to the radial direction, with the polarity of their connections ensuring that the magnetic flux direction alternates in the circumferential direction, as has been explained with reference to FIG. 9.”, Alternating current causes polarity reversal, as is evidenced by Pankratz, U.S. Patent Application Publication 2015/ 0041455, “Electrically conductive materials can be heated by induction This occurs by placing an electrically conductive material in a magnetic field generated by an induction coil. The magnetic field is hereby generated by an alternating current which results in a polarity reversal of the magnetic field at the frequency of the alternating current”).). Thus it would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify Haimer ‘059 in view of Shigefuji and Haimer ‘386 and Kelch with Haimer ‘069 (and as evidenced by Pankratz), to support the AC current going through the coils, allowing for reversal of the polarity or adjusting power which effectuates heating of the holder.
Regarding claim 24, Haimer ‘059 in view of Shigefuji, Haimer ‘386 and Kelch teaches all the limitations of claim 19, as above, but does not further teach an induction coil unit wherein: said coil configuration has a switchable and/or reversible-polarity winding region; and said actuator is adapted to adjust a diameter and/or an axial distance between said winding regions and/or to switch said winding regions of said coil configuration on or off and/or to reverse a polarity of the winding regions.
However, Haimer ‘069 teaches that “said coil configuration has a reversible-polarity winding region” (meaning that the windings support polarity reversal, Haimer ‘069 ¶0099, “the coils are all wound in the same sense with respect to the radial direction, with the polarity of their connections ensuring that the magnetic flux direction alternates in the circumferential direction, as has been explained with reference to FIG. 9.”, Alternating current causes polarity reversal, as is evidenced by Pankratz, U.S. Patent Application Publication 2015/ 0041455, “Electrically conductive materials can be heated by induction This occurs by placing an electrically conductive material in a magnetic field generated by an induction coil. The magnetic field is hereby generated by an alternating current which results in a polarity reversal of the magnetic field at the frequency of the alternating current”).) “and said actuator is adapted to adjust a diameter and/or an axial distance between said winding regions (Haimer ‘059, column 3 line 45) and/or to switch said winding regions of said coil configuration on or off (Haimer ‘059, column 5 lien 45, “on or off”) and/or to reverse a polarity of the winding regions.
Thus it would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify Haimer ‘059 in view of Shigefuji and Haimer ‘386 and Kelch with Haimer ‘069 (and as evidenced by Pankratz), to support the AC current going through the coils, allowing for reversal of the polarity or adjusting power which effectuates heating of the holder and to be able to adjust the tool for proper fit.
Claim 23 is rejected under 35 U.S.C. 103 as being obvious Haimer ‘059 (U.S. Patent 8,963,059) in view of Shigefuji (WIPO Patent Publication WO2004091847A2, attached, hereinafter “Shigefuji”) Haimer ‘386 (U.S. Patent Application Publication 2008/ 0277386) and Kelch (U.S. Patent Application Publication 2001/ 0054471), and further in view of Haimer ‘515 (German Patent Publication DE102016206515A1; previously attached, with Machine English Translation of specification).
Regarding claim 23, Haimer ‘059 in view of Shigefuji, Haimer ‘386 and Kelch and teaches all the limitations of claim 19, as above, but does not further teach wherein said detector is configured for at least one of the following: to optically determine the at least one property of the tool holder held by said holding apparatus based on a shape thereof,
to determine the at least one property of the tool holder held by said holding apparatus based on a weight thereof;
to determine the at least one property of the tool holder held by said holding apparatus based on magnetic properties thereof;
to determine the at least one property of the tool holder held by said holding apparatus based on haptic sensing; or
to determine the at least one property of the tool holder held by said holding apparatus based on ultrasonic imaging.
Now, Haimer ‘059 teaches about different size chuck and holder and he asserts that with different sensor, you can work with different sizes and shapes of holders and coils (Haimer ‘059, column 5 lines 30 -40, “the geometry data of a chuck or a clamping sleeve of a tool holder are determined” by… “digital image processing, laser scanners, distance sensors and similar”; getting a “digital image” based off the lasers and sensors would be getting a parameter or property “based on shape”). Haimer ‘515 teaches an optical sensor for imaging the shape of a tool or even using ultra-sonic waves (Haimer ‘515, ¶0035, “optical detection arrangement” “The image from the camera can …be displayed…so that the operator can use the camera image to examine the tool”; or ¶0010, contactless detection using transmitted light or ultrasonic waves is possible”). Given the teaching of Haimer ‘059 of multiple types of sensors (including the term “and similar”) for imaging (that would be “based on a shape”) it would have been obvious to one of ordinary skill in the art before the time of the invention to substitute the teachings of Haimer ‘515 into the invention of Haimer ‘059 in view of Shigefuji, Haimer ‘386 and Kelch, to modify the invention to have the claimed sensing, either optical or ultrasonic (or other), because the substitution of one known method of sensing for another would have yielded predictable results of assessing the shape or position of the tool to ensure that the tool holder is appropriately configured.
Claims 25, 26 and 27 are rejected under 35 U.S.C. 103 as being obvious over Haimer ‘059 (U.S. Patent 8,963,059) in view of Shigefuji, (U.S. Patent 6,163,734) and Kelch (U.S. Patent Application Publication 2001/ 0054471).
Regarding claim 25, Haimer ‘059 discloses induction coil unit (Haimer ‘059, Abstract, “a device for inductively clamping and unclamping a tool shaft of a tool”) for heating a freely-terminating sleeve portion of a tool holder having a receiving opening (Haimer, receiving bore hole 5, fig. 1, column 2 line 24) formed therein for a shank of a rotary tool (shaft 9), in which the freely-terminating sleeve portion holds the shank of the rotary tool seated in the receiving opening in a press fit and releases the rotary tool upon heating (Haimer ‘059, column 6 lines 29-36; “The exterior diameter of the shaft 9 is then slightly larger than the free nominal diameter of the receiver bore hole 5, so that the shaft 9, when it is inserted in the bore hole 5, is supported in the clamping sleeve 3 through a friction locking press fit for transferring the operating torque. In order to be able to insert the tool shaft 9 into the tool holder 1 and in order to be able to also remove it, the clamping sleeve 3 is expanded through heating.), the induction coil unit comprising:
a coil configuration (Haimer ‘059, “induction coil” 13 and “coil units” 14a and 14b which together make 15, within “coils housings” 17a, and 17b, figs. 1 and 2) enclosing the freely-terminating sleeve portion during the heating operation, said coil configuration having an adjustable geometry (column 6 line 63 – column 7 line 3, adjustment of the two coil units 14a a, 14b is facilitated along the rotation axis 7);
a magnetic flux concentrator configuration (sleeve shaped concentrators, 19a and 19b, concentrator ring 21) disposed on a side of said coil configuration adjacent a free end of the freely-terminating sleeve portion, said magnetic flux concentrator configuration being disposed at least near the free end of the freely-terminating sleeve portion of the tool holder and being made of a magnetic material that is substantially electrically non-conductive (Haimer ‘059, column 7 lines 21-22 “[concentrators are] made from magnetically conductive but electrically nonconductive material, like e.g., an oxide ceramic material, in particular ferrite, see Haimer ‘414, U.S. Patent 9,278,414, Column 7 lines 48-50 which teaches that “concentrator elements [] are entirely comprised of magnetically soft, substantially electrically nonconductive material, e.g. ferrite”);;
at least one actuator for adapting at least one operating parameter of the heating operation, said actuator being configured to adjust the geometry of said coil configuration (Haimer ‘059, column 5 lines 23-26, “and the positional adjustment of the coil units of the induction coil assembly separately adjustable relative to one another, which in particular provides controllable adjustment options for particular applications”)
a controller (Haimer, ‘059, column 5 lines 30-51, “automated operations…can be configured with a data carrier… associated through digital image processing, with laser scanners, distance sensors and similar… and power supply can be turned off and on through… the shrink electronics”) being in data communication, respectively, with said at least one detector (column 5 lines 36-37; “associated through digital image processing, laser scanners, distance sensors and similar”) to obtain data relating to the tool holder, and with said at least one actuator to direct an adaptation of the at least one operating parameter, said controller being configured to direct the adaptation of the at least one operating parameter by adjusting the geometry of said coil configuration based on the at least one property of the tool holder detected by said at least one detector (adjusted based on one of “digital image processing, laser scanners, distance sensors and similar”); and
a memory connected to said controller, said memory storing data that enable said controller to determine a type of tool holder (Haimer ‘059, “(Haimer ‘059, Column 11 line 62 “[T]he respective geometry and shrink parameters with respect to different shrink fit chucks can either be read in from an external data source or through a suitable scanner which reads from a respective data carrier on the shrink fit chuck and thus facilitates the respective adjustment and control of the two motors”),
.
Haimer ‘059 is silent regarding at least one detector for automatically detecting “a coding furnished on the tool holder in order to determine at least one property of the tool holder, the coding being an optical coding”, and the memory storing data that enables the controller to determine a type of tool holder “based on information obtained from the detector” and “to adjust a positioning of said coil configuration along an axial direction of the tool holder during the heating operation”.
However, Haimer ‘059 already teaches about different size chuck and holder and he asserts that with different sensors, you can work with different sizes and shapes of holders and coils (Haimer ‘059, column 12 lines 1-8, “The geometric data of the chuck can thus be automatically determined in different manners e.g., through digital image processing, laser scanners and distance sensors through which the shrinking parameters can automatically be assigned according to the size of the shrink fit chuck and the coil can be automatically adjusted with respect to its axial length. A slide can be used for both motors for the intended space saving and compact configuration.”) and a detector (column 11 line 62 - column 12 line 7). However, Shigefuji teaches “a coding furnished on the tool holder held by said holding apparatus in order to determine at least one property of the tool holder, the coding being an optical coding”, (Shigefuji, column 1, lines 34-55, “ During the operation of the press, desired upper and lower tools are selected and taken out from the magazine on the basis of such tool-pair information, so that the tools are changed with old tools on the punch press. The tool-pair information includes tool shape information, tool size information and tool clearance information. The tool information includes a tool manufacturing number and a tool manufacturing date. Such information may be represented by bar codes that is provided on the surface of the tools to be read by a bar code scanner. A bar code is an optical coding, i.e. coding read by optics). Thus, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention, to modify Haimer ‘059 with the teachings of Shigefuji, to have optical markings for inserting the tool into the holder and knowing its identity, and thus knowing the required insertion configuration and parameters for quick changes, and this recognizing that Haimer ‘058 is very interested in determining the geometry and configuration of its tool and chuck, and it does this with scanners of its own, so this would be a beneficial modification (Haimer ‘059, column 12 lines 1-7, “geometric data of the chuck”; column 5 lines 30-35, “the respective geometry data of a chuck or a clamping sleeve of a tool holder are determined automatically for a fully automated shrinking process, wherein the chuck or the tool holder can be configured with a respective data carrier.” Wherein, “outer dimension, a wall thickness, and an axial extension” are all “geometry data” of the tool holder or the chuck) having the tool be identified quickly and easily with a code, and it would be helpful to access the memory and to determine a property of the tool holder “based on the information from the detector” so it is for quick and easy identification and configuration.
And while Haimer ‘059 in view of Shigefuji and Haimer ‘386 teaches all the limitations above, they still do not teach “to adjust a positioning of said coil configuration by way of a movable stop for said coil configuration”. However, a movable and adjustable stop is a conventional method of adjusting coils, as taught in Kelch in his method for shrink an thermal clamping. Thus, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention, to modify Haimer ‘059 in view of Shigefuji and Haimer ‘386 with the teachings of Kelch, to have a movable stop for adjusting the induction coil, in order to ensure that the movement of the coil is accurate and produces an optimum electric field for optimum coupling allowing for proper clamping.
Regarding claim 26, Haimer ‘059 in view of Shigefuji and Kelch teaches all the limitations of claim 25, as above, and further teaches wherein the coding is selected from the group consisting of an optical coding, an inscription, a radio frequency identification chip and a mechanical marking (Shigefuji, id. optical coding, barcode).
Regarding claim 27, Haimer ‘059 discloses an induction coil unit ( Haimer ‘059, Abstract, “a device for inductively clamping and unclamping a tool shaft of a tool”) for heating a freely-terminating sleeve portion of a tool holder having a receiving opening (Haimer, receiving bore hole 5, fig. 1, column 2 line 24) formed therein for a shank of a rotary tool (shaft 9) , in which the freely-terminating sleeve portion holds the shank of the rotary tool seated in the receiving opening in a press fit and releases the rotary tool upon heating (Haimer ‘059, column 6 lines 29-36; “The exterior diameter of the shaft 9 is then slightly larger than the free nominal diameter of the receiver bore hole 5, so that the shaft 9, when it is inserted in the bore hole 5, is supported in the clamping sleeve 3 through a friction locking press fit for transferring the operating torque. In order to be able to insert the tool shaft 9 into the tool holder 1 and in order to be able to also remove it, the clamping sleeve 3 is expanded through heating.), the induction coil unit comprising:
a holding apparatus (clamping sleeve 3, column 6 lines 42 et seq.) configured for holding the tool holder during a heating operation;
a coil configuration (Haimer ‘059, “induction coil” 13 and “coil units” 14a and 14b which together make 15, within “coils housings” 17a, and 17b, figs. 1 and 2) enclosing the freely-terminating sleeve portion during the heating operation, said coil configuration having an adjustable geometry (column 6 line 63 – column 7 line 3, adjustment of the two coil units 14a a, 14b is facilitated along the rotation axis 7) ;
a magnetic flux concentrator configuration (sleeve shaped concentrators, 19a and 19b, concentrator ring 21) disposed on a side of said coil configuration adjacent a free end of the freely-terminating sleeve portion, said magnetic flux concentrator configuration being disposed at least near the free end of the freely-terminating sleeve portion of the tool holder and being made of a magnetic material that is substantially electrically non-conductive (column 7 lines 21-22 “[concentrators are] made from magnetically conductive but electrically nonconductive material, like e.g., an oxide ceramic material, in particular ferrite, see Haimer ‘414, U.S. Patent 9,278,414, Column 7 lines 48-50 which teaches that “concentrator elements [] are entirely comprised of magnetically soft, substantially electrically nonconductive material, e.g. ferrite”);
at least one actuator (element 70 with motors 72 & 74; column 11 line 40) for adapting at least one operating parameter of the heating operation, said actuator being configured to adjust the geometry of said coil configuration (Haimer ‘059, column 5 lines 23-26, “and the positional adjustment of the coil units of the induction coil assembly separately adjustable relative to one another, which in particular provides controllable adjustment options for particular applications”; column 11 line 39, adjusting the coil units relative to one another;. column 5 lines 35-40, “the coil can be automatically adjusted”; column 12 lines 3-6) and to adjust a positioning of said coil configuration during the heating operation (Haimer ‘059, “column 3 lines 13-14, the position of the coil units can be adjustable or alignable”;
a controller (Haimer, ‘059, column 5 lines 30-51, “automated operations…can be configured with a data carrier… associated through digital image processing, with laser scanners, distance sensors and similar… and power supply can be turned off and on through… the shrink electronics”), being in data communication, respectively, with said at least one detector to obtain data relating to the tool holder, and with said at least one actuator to direct an adaptation of the at least one operating parameter, said controller being configured to direct the adaptation of the at least one operating parameter by adjusting the geometry of said coil configuration based on the at least one property of the tool holder detected by said at least one detector.
Haimer ‘059 does not disclose at least one detector for automatically detecting a coding furnished on the tool holder, said coding being selected from the group consisting of an optical coding, a textual marking, an RFID chip, and a mechanical marking and relating to at least one property of the tool holder held by said holding apparatus, the at least one property being selected from the group consisting of an outer dimension, a wall thickness, and an axial extension of the tool holder; and said actuator having a movable stop means for said coil configuration.
However, Shigefuji, directed to changing tools for working metal, teaches at least one detector for automatically detecting a coding furnished on the tool holder, said coding being selected from the group consisting of an optical coding, a textual marking, an RFID chip, and a mechanical marking and relating to at least one property of the tool holder held by said holding apparatus, the at least one property being selected from the group consisting of an outer dimension, a wall thickness, and an axial extension of the tool holder (Shigefuji, column 1, lines 34-55, “ During the operation of the press, desired upper and lower tools are selected and taken out from the magazine on the basis of such tool-pair information, so that the tools are changed with old tools on the punch press. The tool-pair includes tool shape information, tool size information and tool clearance information. The tool information includes a tool manufacturing number and a tool manufacturing date. Such information may be represented by bar codes that is provided on the surface of the tools to be read by a bar code scanner”. A bar code is an optical coding, i.e. coding read by optics). Thus, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention, to modify Haimer ‘059 with the teachings of Shigefuji and Carberry, to have optical markings for inserting the tool into the holder and knowing its identity, and thus knowing the required insertion configuration and parameters for quick changes, and this recognizing that Haimer ‘058 is very interested in determining the geometry and configuration of its tool and chuck, and it does this with scanners of its own, so this would be a beneficial modification (Haimer ‘059, column 11 line 62 - column 12 lines 7, “geometric data of the chuck”; column 5 lines 30-35, “the respective geometry data of a chuck or a clamping sleeve of a tool holder are determined automatically for a fully automated shrinking process, wherein the chuck or the tool holder can be configured with a respective data carrier.” Wherein, “outer dimension, a wall thickness, and an axial extension” are all “geometry data” of the tool holder or the chuck) having the tool be identified quickly and easily with a code
And while Haimer ‘059 in view of Shigefuji and Haimer ‘386 teaches all the limitations above, they still do not teach “said actuator having a movable stop means for said coil confiration”. However, a movable and adjustable stop is a conventional method of adjusting coils, as taught in Kelch in his method for shrink an thermal clamping. Thus, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention, to modify Haimer ‘059 in view of Shigefuji and Haimer ‘386 with the teachings of Kelch, to have a movable stop for adjusting the induction coil, in order to ensure that the movement of the coil is accurate and produces an optimum electric field for optimum coupling allowing for proper clamping.
Claim 28 is rejected under 35 U.S.C. 103 as being obvious over Haimer ‘059 (U.S. Patent 8,963,059) in view of Shigefuji (WIPO Patent Publication WO2004091847A2, previously attached, hereinafter “Shigefuji”), and Kelch (U.S. Patent Application Publication 2001/ 0054471) and further in view of Pfau (U.S. Patent Application 2006/ 0163245).
Regarding claim 28, Haimer ‘059 in view of Shigefuji and Kelch teaches all the limitations of claim 27, as above, but does not further teach an apparatus comprising: at least one suction device for vapor produced during heating and/or a sealing element for cooling media, said actuator is adapted to adjust a positioning of said at least one suction device and/or said at least one sealing - 20 -HAI-0094 element for cooling media in a tool holder's axial and/or radial direction during the heating operation. However, Pfau teaches a suction device to get rid of vapor or gases produced by the holder during the heating process that arise from the holder (Pfau, Abstract, gas suction device for evacuating gases, fig. 1). The advantage would be to ensure that the workspace remains clean and not offensive while inserting the tools, thus it would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify Haimer ‘059 in view of Shigefuji and Kelch with Pfau, to have a suction device to capture the escaping gases to make for a more pleasant working environment (Pfau, ¶0036-0038, prevents gases “emerg[ing] into surroundings”).
Response to Arguments
Applicant’s arguments, dated 13 March 2026 with respect to claim(s) 19-28 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Specifically, a new reference was added regarding the movable stop.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Please see previously filed forms PTO-892.
