DEFINITION

Classification: 29/25.41

ELECTRIC CONDENSER MAKING:

Miscellaneous process or apparatus for making an electric condenser which is not classifiable in the specific classes relating to the manufacture of articles.

(1) Note. This and indented subclasses do not include the manufacture of electric condensers of the electrolytic type. The patents relating to the manufacture of an electrolytic condenser are in Class 29, subclasses 25.01+, or in the classes referred to in the search notes of that subclass.

(2) Note. This and the indented subclass are not limited to the manufacture of electric condensers where a metal working step is involved, but include the manufacture of such devices from any material where no specific class provides for the claimed subject matter.

(3) Note. Where the patent includes a claim to the article manufactured, in addition to claims for the process or apparatus, the patent is classified in the article class and cross-referenced to these subclasses.

(4) Note. For electric condensers of the type manufactured by the process or apparatus of this subclass, under "SEARCH CLASS", see Class 361, Electricity: Electrical Systems and Devices, subclasses 271+.

(5) Note. Work holders are usually classified with the apparatus for performing the operation. Under "SEARCH CLASS",

see Class 269, Work Holders, for miscellaneous work holders for assembly operations.

(6) Note. Process or apparatus for making a condenser and testing that condenser is classified with the art which provides for the manufacturing operation. SEE OR SEARCH THIS CLASS, SUBCLASS:

17.1+, for a process or apparatus for forming thin sheet metal and metal foil.

25.01+, and see (1) Note, above.

33+, for miscellaneous organized machines adapted to perform a plurality of operations upon metal.

400.1+, for a process for making metallic articles and a process of working metal not classified in specific classes. Note subclasses 592.1+ for miscellaneous process of making an electrical device which includes a metal working operation. Subclass 630 provides for a process for making a contact or terminal for an electric condenser and other electrical device.

SEE OR SEARCH CLASS

53, Package Making,

470+, and 239 for a method of or apparatus for merely placing a condenser in a container or receptacle and filling the container or receptacle with a fluent material.

106, Compositions: Coating or Plastic, for a miscellaneous coating, impregnated article or plastic composition.

118, Coating Apparatus, for miscellaneous coating apparatus.

156, Adhesive Bonding and Miscellaneous Chemical Manufacture, for a process for making a condenser where the process recites no more than operations of laminating or laminating and impregnating. The lamination may be a winding operation.

204, Chemistry: Electrical and Wave Energy, for electrolytic and wave energy method or apparatus for treating, coating, or forming an article. 209, Classifying: Separating, and Assorting Solids,

546+, for a process or apparatus of testing a group of electric condensers and assorting them according to their electrical properties.

216, Etching a Substrate: Processes,

6, for forming a capacitor.

228, Metal Fusion Bonding, for joining of work portions by soldering, welding, or brazing.

242, Winding, Tensioning, or Guiding,

444.1+, for simultaneously winding an electrical conductor and dielectric strip to form an article such as a condenser without further manufacturing.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes, for a process of working, molding, or shaping miscellaneous plastic materials, per se, or combined with other operations within the class definition. See Class 264 definitions for the line between this class (29) and Class 264. Some subclasses in Class 264 which are specific to production of electrical components or devices are

104+, 272.11+ and 615.

269, Work Holders, see (5) Note, above.

324, Electricity: Measuring and Testing, 60, for a process or apparatus for making an electrical test of an electric condenser. Also see (4) Note above.

361, Electricity: Electrical Systems and Devices,

271+,. See (4) Note, above.

413, Sheet Metal Container Making,

1+, for the method of fabricating a sheet metal can.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus, for molding apparatus for shaping or reshaping, per se, plastic materials (e.g., resins, clay, etc.) or with combined operations not otherwise provided for. See, especially,

110+, for composite article manufacturing involving a preform and fluent material.

427, Coating Processes,

79+, for a coating process, per se, wherein the product is a condenser, capacitor, or a subcombination thereof.

428, Stock Material or Miscellaneous Articles, for a stock material product in the form of a single or plural layer web or sheet and

432+, and 457+ for a plural layer sheet including a layer of metal next to a layer of nonmetal material.
