DEFINITION

Classification: 445/73

Having evacuation or degasification means or means to introduce gas, vapor, liquid or solid treating agent:

(under subclass 60) Apparatus which include means for (1) applying gaseous material, aerosol, liquid, or solid treating material within an enclosure of an electric lamp or electric space discharge device or (2) removing, absorbing, or adsorbing gaseous material or aerosol from within an enclosure of the lamp or device.

(1) Note. Merely stating that an apparatus has exhaust heads does not make the apparatus an exhausting or gas filling machine where none of the operations performed on the article held in the exhaust heads are either exhausting or gas filling.

(2) Note. This subclass includes only such apparatus as is used during manufacture of the lamp or discharge device. If the claimed subject matter is intended to be used during the operation of the lamp or discharge device and to thereby control the operating characteristics of the lamp or discharge device, the patent is excluded and will be found in the classes referred to in the notes below.
