WITH FRANGIBLE CAPSULE CONTAINING GETTER, GAS OR VAPORGENERATING MATERIAL:
(under the class definition) Subject matter which includes a sealed capsule holding a getter or a gas or vapor generating material, capable of being opened within the envelope so that the material can enter the inside of the envelope to perform some function.
(1) Note. The container can be unsealed by breaking the container, melting at least a portion of the container, penetrating the container, or destroying the sealed container in any way to cause the material to enter the inside of the envelope.
(2) Note. Here is the subcombination of an envelope of a lamp or discharge device and a frangible container with material within the inside of the envelope.
(3) Note. Material in the container may be solid, gas or liquid.

7, for a gas or vapor in a receiver with the evacuation of the receiver for processes.
252, Compositions, 181.1+, for getter compositions or gas or vapor generating material compositions which may be stored in a capsule.
417, Pumps,
48+, for electric or getter type pumps where the claims do not state the gettering action is within a lamp or discharge device (single disclosure appears to control the classification).
445, Electric Lamp or Space Discharge Component or Device Manufacturing,
9+, for a process which includes generating gas or vapor or coating by gas vapor, mist or smoke within an envelope combined with an assembly operation, subclass 16 for a process of gas introduction into an electric lamp or discharge device with generating gas or vapor within the envelope, subclass 19 for a process which includes the generating a gas or vapor, mist or smoke within an envelop which requires induction heating to release the generated material, subclasses 38+ for a process which includes the evacuation of a lamp or discharge device and some other operation, subclasses 53+ for a process which includes evacuation, degasification or gas, vapor or liquid introduction into a lamp or discharge device envelope and the step of gettering within the envelope and subclasses 70 and 73 for apparatus to evacuate, degasify and/or gas, vapor or liquid introduction into a lamp or discharge envelope.
