DEFINITION

Classification: 445/1

PROCESS:

(under the class definition) Method.

(1) Note. This and the indented subclass include the manufacture of lamps and space discharge devices from any material where no specific class provided for the claim subject matter.

SEE OR SEARCH CLASS

8, Bleaching and Dyeing; Fluid Treatment and Chemical Modification of Textiles and Fibers,

115.51+, for processes for the chemical modification of textiles and fibers, especially subclasses 116.1+ for such processes for treating vegetable fibers (cotton, bamboo, etc.,) and subclass 128.1 for such processes for treating animal fibers, subclass 140 for methods of carbonizing textiles and fibers by means of fluid treatment and chemical modification.

29, Metal Working, appropriate subclasses, for process of manufacturing miscellaneous electrical devices, note especially

2, for battery-grid making, 25.01+ for semiconductor or barrier layer device making, 25.35 for piezoelectric device making, 25.41+ for electric condenser making, and 592.1+ for processes of manufacturing various electric devices. See also subclasses 426.1+ and 428+ for miscellaneous processes of disassembly, and assembly respectively, and subclasses 17.2+ for processes for forming thin sheet metal and metal foil process which includes coating a form and then removing the form to leave an article of thin sheet metal or metal foil. 34, Drying and Gas or Vapor Contact With Solids, the subclasses indented under the title "Processes", for miscellaneous methods of treating articles and materials by, (1) separating liquids from the article or the material by drying, (2) the contacting of the article or the material with either or both gases or vapors, note especially

427, for such processes combined with a diverse type process and subclasses 437+ for processes peculiar to hollow articles.

53, Package Making,

403+, for processes of gas filling and/or evacuating packages or receptacles including lamps or electric space discharge devices and closing same.

65, Glass Manufacturing,

17.1+, for miscellaneous process of, (1) making and/or treating a glass product or stock, or (2) re-working and/or treating a glass preform or stock, or (3) such working or treating combined with severing, perforating or abrading of the glass; see especially subclass 34 for glass-working combined with sealing off of a gas evacuating opening and subclasses 26+ for a process of fusion bonding of glass to glass or metal.

72, Metal Deforming,

253.1+, for extruding metal (e.g., electrodes), and 362+ (particularly 364 and 377) for processes thereof which do not involve specified apparatus, 199+ for disclosure of rolling metal, and 274+ for disclosure of drawing wire through an orifice.

106, Composition: Coating or Plastic, for miscellaneous coating, impregnating or plastic compositions, excepting those which are limited to use for making filaments, electrodes and shields for electric lamps and electric space discharge devices which are in Class 252 below. Class 106

provides for processes of making compositions within its class definition even though the step of molding, extruding, spinning or sheeting is claimed broadly, also the statement that heat and/or specific pressure are recited will not be enough of itself to take a patent claiming a process of preparing a composition out of Class 106. Class 106, therefore, includes the process of producing articles from plastic materials within the limits set forth above.

134, Cleaning and Liquid Contact With Solids, for processes of cleaning or treating various solids (including electrodes and blanks) with liquids, and including the acid treatment of metals in

3, 27, 28, and 41. 140, Wireworking, appropriate subclasses, for processes of making articles from wire by wireworking operations.

71.5+, provides for making or shaping parts of electric space discharge devices, such as grids, filaments or other electrodes by wireworking operations, and methods of attaching such electrodes to their support wires where the method involves only wireworking operations.

141, Fluent Material Handling, With Receiver or Receiver Coacting Means,

4, and 8 for methods and subclasses 65+ for apparatus pertaining to the evacuation of and/or filling receivers with gas or vapor including lamps or electric space discharge devices.

148, Metal Treatment, appropriate subclasses for process of treating metal to modify or maintain the internal physical structure (i.e., microstructure) or chemical properties of metal. If metal casting, fusion bonding, machining, or working is involved there is a requirement of significant heat treatment as described in section III, A, of the Class 148 definition. Note that Class 148,

240+, provides for the reactive coating of metal wherein an external agent combines with a component of the metal substrate to produce a coating on the metal substrate that contains the component of the metal substrate.

156, Adhesive Bonding and Miscellaneous Chemical Manufacturing,

47+, for making electrical conductors of indefinite length under the class definition, and subclasses 60+ for processes of surface bonding and/or assembly under the class definition.

174, Electricity: Conductors and Insulators, appropriate subclasses, for electrical conductor and insulators structures, per se, note especially

17.05+, for hermetically sealed envelope type housings for vacuum or fluids and 50.5+ for hermetically sealed envelope type housings which may include electrical connecter or conductor structure or insulator structure.

204, Chemistry: Electrical and Wave Energy, 155+, for chemical preparation of a compound or element by using electrical or wave energy in a magnetic field, subclasses 164+ for chemical preparation of a compound or element by using an electrostatic field or electrical discharge and subclasses 192.1+ for coating, forming, or etching by sputtering. Class 204 provides for combined coating operations where only one such coating method is a Class 204 method. Class 204 also provides for some other processes which include a plurality of operations, even if only one of the operations is a Class 204 operation.

205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compositions,

67+, for electroforming in which the material deposited to form the article is not intended to remain on the base or form upon which deposition is made, subclasses 80+ for electrolytic coating, subclasses 149+ for coating specified shapes, and other appropriate subclasses for electrolytic etching or treating of articles (e.g., electrodes, etc.). Class 205 provides for combined coating operations where only one such coating method is a Class 205 method. Class 205 also provides for some other processes which include a plurality of operations, even if only one of the operations is a Class 205 operation.

219, Electric Heating,

104+, for methods of inductively heating metal or nonmetal, and subclass 162 for methods of electrically heating metal.

252, Compositions,

500+, for electrically conductive and emissive compositions and devices defined only in terms of their composition. These subclasses in Class 252 provide for the same manufacturing operations as the subclasses in Class 106, relative Class 106 and for other classes which provide for methods of preparing the compositions and devices see the above statement concerning Class 106.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes, appropriate subclasses, for processes of working, molding or shaping miscellaneous plastic materials, per se, or combined with other operations, within the class definition. See the Class 264 definitions for the line between this class (445) and Class 264. Some subclasses in Class 264 which are specific to production of electrical components or devices are 104+, 272.11 and 614+.

359, Optics: Systems (Including Communication) and Elements,

900, for a cross-reference art collection of optical methods.

362, Illumination, 257+, for means and processes for casting visible radiant energy in at least one direction to render objects in that direction visible.
