Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This is the residual and generic class of process and apparatus for the manufacturing, fabrication, repair, salvage, assembly, disassembly or other treatment of an electric lamp, liquid crystal display device or an electric space discharge device which process or apparatus is not elsewhere classified.

(1) Note. An electric lamp is defined for the purpose of classification as a device for converting electric energy into visible light or ultraviolet light.
(2) Note. An electric space discharge device is defined for the purpose of classification as including any device which is intended to have an electric current flow between two spaced parts or electrodes, at least part of the path followed by the discharge constituting a gas, vapor, or vacuum. Examples of an electric space discharge device include spark gap, spark plug, radio tube, X-ray tube, cathode-ray tube, laser tube, arc tube, gas or vapor discharge lamp, flash lamp and lightning arrester of the electric space discharge type.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

The line between this class and all other classes which provide for either apparatus or process for the manufacture or treatment of electric lamp, liquid crystal display device or electric space discharge device is that all combined process and all apparatus which are intended to perform a plurality of different processes are classified in this class when one of the operations performed is an operation specifically provided for in this class. For the lines between particular classes not included in the general line above, see the notes to this section, below, and References to Other Classes, below.

For electric lamp and electric space discharge device, including the structure of a self-baking or Soederberg electrode which is formed from a plastic mass during the operation of the device, see References to Other Classes, below.

The line between this class (445) and Class 29 is as follows: (a) where a claim is presented which recites manufacturing another structure, e.g., a lamp base, PCB; either specific or nominal and specific Class 445 device manufacture, placement of the original will be in Class 445; (b) where there is specific recited manufacture of another structure and, as a step in that manufacture, a nominally recited Class 445 device is nominally united to the base, placement is in Class 29 (merely screwing a light bulb into a base is considered nominal); and (c) the manufacture of other structures intended to be used with a Class 445 device is in Class 29 or other manufacturing classes.

The subject matter of the class (445) was found in Class 316 and abolished subclasses 25.1+ of Class 29. No other portions of Class 29 have been screened for Class 445 subject matter.

(1) Note. Original placement within this subclass requires that the gaseous material or aerosol must be within the enclosure of the lamp or discharge device and deposition operation must include some operation peculiar to the manufacture of electric lamps or electric space discharge devices so that the process is not of general utility.
(2) Note. Methods which include introducing a material which is in the gaseous or vapor state prior to its introduction in the envelope and which do not involve forming a coating from the gas or vapor material are excluded from these subclasses.
(3) Note. The coating applied to the part of the lamp or discharge device need not serve any useful function as a coating, but may be merely a procedure adapted to eliminate the vapor from the interior of the envelope of the lamp or discharge device, or the vaporizing and subsequent deposition may be for procuring the material in a vaporized state so that it will be an active getter.

[List of Patents for class 445 subclass 10]    10Controlled vaporizing or coating:
 This subclass is indented under subclass 9.  Method which includes (1) regulating the amount of gaseous material or aerosol produced or created or (2) regulating the amount of material in the deposition layer or coating.
(1) Note. This Subclass does not include methods where a predetermined amount of material is introduced into the envelope and this material is then used to generate as much gas or vapor as it is capable of generating in order to obtain a predetermined amount of gas or vapor within the envelope.

(1) Note. Merely producing a coating upon two or more parts of the lamp or discharge device such as upon two different electrodes, where only a single coating operation is involved is not within the definition of this subclass.
(2) Note. The coatings produced in this subclass may be superposed or upon separate parts of the lamp or discharge device.
