DETAILED ACTION
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claims 1 and 9 are amended
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 1-14 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by James (US 20180330862 A1).
Regarding Claim 1:
James teaches that an variable-impedance electric transformer (100. Fig. 1), comprising one or more transformation phases (102, Fig.1; para 0034-0040) wounding around a magnetic core (202, Fig. 4; para 0041-0051), wherein at least one transformation phase includes:
conductive windings (208A, 208B; Fig. 3; para 0053-0063)
a first impedance-varying auxiliary winding (see Fig. 5A) divided into impedance
circuit modules (304F1-F3 , Fig. 3), the first impedance-varying auxiliary winding having a magnetic polarity (see para 0050);
a second impedance-varying auxiliary winding (see Fig. 5A) divided into impedance circuit modules (304E1-E3, Fig. 3), the second impedance-varying auxiliary winding having an inverse magnetic polarity (see para 0060) to the magnetic polarity of the first impedance-varying auxiliary winding, wherein the first impedance-varying auxiliary winding and second impedance-varying auxiliary winding have a same number of impedance circuit modules (both first and second impedance-varying auxiliary winding have 3 circuit modules with same winding; see para 0045);
wherein the first impedance-varying auxiliary winding and second impedance-varying auxiliary winding are connected in series (see Fig. 3), defining impedance variation modules by interposing the impedance circuit modules one by one, each impedance variation module includes one impedance circuit modules of the first impedance-varying auxiliary winding connected in series with one impedance
circuit modules of the second impedance-varying auxiliary winding, and each impedance variation module having a impedance tap (see Fig. 3);
a stepped-impedance-tap selector (i.e. switch, 116) configured to be electrically coupled to the impedance taps of the impedance variation modules; and
an impedance controller (not shown. Implicit in switch 116, see Claim 8) configured to control the stepped-impedance-tap selector for varying the impedance of the transformation phase or the electric transformer, wherein said same number of impedance circuit modules.
As of functional limitation “wherein said same number of impedance circuit modules permits the impedance of the electric transformer to change without affecting a transformation ratio during operation under load” It is seen that James certainly teaches substantially identical structure as shown in Fig. 1 and 3 such as a first impedance-varying auxiliary winding, second impedance-varying auxiliary winding, same number of impedance circuit modules in same filed of endeavor. As per MPEP § 2112.01.I guideline, where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established. In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977).
Therefore, it is inherent to be labeled as wherein said same number of impedance circuit modules permits the impedance of the electric transformer to change without affecting a transformation ratio during operation under load.
Regarding Claim 2:
As applied to claim 1, James teaches that the electric transformer is a column- type (construed from Fig. 1) {or armored-type electric transformer}.
Regarding Claim 3:
As applied to claim 2, James teaches that the electric transformer is a column-type electric transformer (construed from Fig. 1), and the first impedance-varying auxiliary winding and second impedance-varying auxiliary winding are arranged radially (see Fig. 3) or axially to the conductive windings.
Regarding Claim 4:
As applied to claim 2, James teaches that the electric transformer is armored- type electric transformer, and the first impedance-varying auxiliary winding (see Fig. 3) and second impedance-varying auxiliary winding are arranged in a stacked manner in side-by-side relationship to the conductive windings (see Fig. 4).
Regarding Claim 5:
As applied to claim 1, James teaches that the conductive windings are a primary winding (206, Fig. 4) and a secondary winding (see para 0053).
Regarding Claim 6:
As applied to claim 1, James teaches that the impedance controller is configured for varying the impedance of at least one transformation phase or the electric transformer under load (see claim 3, 5 and 8; para 0097).
Regarding Claim 7:
As applied to claim 1, James teaches that the electric transformer is a power (see para 0034) or distribution electric transformer.
Regarding Claim 8:
As applied to claim 1, James teaches that the electric transformer is a single- phase or multi-phase transformer (see para 0034-0040)
Regarding Claim 9:
James teaches that a method (see claims 16-20) for varying the impedance in an electric transformer (100, Fig. 1) comprising one or more transformation phases wounding around a magnetic core (202, Fig. 4), the method comprising the steps of:
disposing conductive windings (208A, 208B; Fig. 3; para 0053-0063) ;
disposing a first impedance-varying auxiliary winding (see Fig. 5A) divided into impedance circuit modules (304F1-F3 Fig. 3), the first impedance-varying auxiliary winding having a magnetic polarity (see para 0050);
disposing a second impedance-varying auxiliary winding (see Fig. 5A) divided into impedance circuit modules (304 E1-E3 Fig. 3), the second impedance-varying auxiliary winding having an inverse magnetic polarity (see para 0060) to the magnetic polarity of the first impedance-varying auxiliary winding, wherein the first impedance-varying auxiliary winding and second impedance-varying auxiliary winding have a same number of impedance circuit modules (both first and second impedance-varying auxiliary winding have 3 circuit modules with same winding; see para 0045),
connecting the first impedance-varying auxiliary winding and second impedance-varying auxiliary winding in series (see Fig. 3), by interposing the impedance circuit modules one by one for defining impedance variation modules, each impedance variation module includes one impedance circuit modules of the first impedance-varying auxiliary winding connected in series with one impedance circuit modules of the second impedance-varying auxiliary winding, and each impedance variation module having an impedance tap;
electrically coupling a stepped-impedance-tap selector (116) to the impedance taps of the impedance variation modules; and
controlling, by an impedance controller (not shown. Implicit in switch 116), the stepped-impedance-tap selector for varying the impedance of the transformation phase or the electric transformer.
As of functional limitation “wherein said same number of impedance circuit modules permits the impedance of the electric transformer to change without affecting a transformation ratio during operation under load” It is seen that James certainly teaches substantially identical structure as shown in Fig. 1 such as a first impedance-varying auxiliary winding, second impedance-varying auxiliary winding, same number of impedance circuit modules in same filed of endeavor. As per MPEP § 2112.01.I guideline, where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established. In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977).
Therefore, it is inherent to be labeled as wherein said same number of impedance circuit modules permits the impedance of the electric transformer to change without affecting a transformation ratio during operation under load.
