DEFINITION

Classification: 445/53

Including evacuating, degasifying or getter or fluent material introduction:

(under subclass 1) Method which includes (1) applying gaseous material, aerosol, liquid or other fluent material within an enclosure of the electric lamp or electric space discharge device or (2) removing, absorbing or adsorbing material occluded gaseous material, or aerosol from within an enclosure of the lamp or device.

SEE OR SEARCH THIS CLASS, SUBCLASS:

38+, for a method of assembly or disassembly including evacuating, degasifying or gas, vapor, liquid or solid introduction.

SEE OR SEARCH CLASS

34, Drying and Gas or Vapor Contact With Solids, the subclasses indented under the title "Processes" which is the generic place for processes of contacting of solids with either or both gases or vapors, and for miscellaneous processes for the separation of liquids from solids by drying. Note especially

427, for such processes combined with a diverse type process and subclasses 437+ for the processes peculiar to hollow articles. Class 34 includes processes for drying a material by placing the material in a chamber and evacuating the chamber. See the notes to the class definition and the subclass definitions of Class 34 for other classes which provide for such processes.

53, Package Making, 403+, for methods of gas filling and/or evacuating of receptacles combined with closing, and see (3) Note and the reference to Class 53 under "SEARCH CLASS" in the class definition of this class (445) for the line.

65, Glass Manufacturing,

34, for a glassworking process including sealing off of a gas evacuating opening.

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

4, 8 and 65+ for methods of and apparatus for gas filling and/or evacuating or receptacles.

148, Metal Treatment, appropriate subclasses for processes of treating solid or semi-solid 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 the Class 148 definition. Class 148,

206+, takes as original processes of carbonizing or nitriding

a metal substrate with an external source of carbon or nitrogen including the use of gas therefor. Moreover, Class 148, subclasses 240+, takes as original processes of reactive coating of metal with an external gaseous agent that combines with a component of the metal substrate to form a coating thereon which contains a component of the metal substrate.

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

687+, for electrolytic methods of removing occluded gases from materials.

222, Dispensing,

1+, for processes of dispensing and subclasses 3+ for vapor or gas dispensing. 264, Plastic and Nonmetallic Article Shaping or Treating: Processes, appropriate subclasses, particularly

500+, for processes within the class definition, for molding or shaping plastic materials which include the step of directly applying fluid pressure or vacuum to the work or molding material. For formation of electrical articles, per se, see particularly subclasses 104+ and 614+.

313, Electric Lamp and Discharge Devices,

549+, for electric lamps and electric space discharge devices which are provided with means for regulating the gas or vapor pressure in the envelope of the lamp.

315, Electric Lamp and Discharge Devices: Systems,

108+, for electrical systems for supplying electric energy to electric space discharge devices of the gas or vapor filled type, the system including means to regulate the gas or vapor pressure in the envelope of the discharge device.

378, X-Ray or Gamma Ray Systems or Devices,

91+, for methods of energization and electrical control of space discharge devices producing X-rays.

417, Pumps,

48+, for electrical or getter type devices.

423, Chemistry of Inorganic Compounds,

210+, for purification or separations of gases by a chemical reaction.
