DEFINITION

Classification: 313/285

(under subclass 284) Devices having the electrode supported by a supporting wire, rod, or tube, which is supported by the envelope.

(1) Note. The supporting wire, rod or tube is sometimes sealed into the stem or press of the envelope and is usually used as the lead-in wire for the electrode.

SEE OR SEARCH THIS CLASS, SUBCLASS:

252+, and the subclasses specified in the notes thereto where the device is a discharge device having a plurality of electrodes supported by the envelope.

271+, and the subclasses specified in the notes thereto where the electrode which is supported is a filament.

282, where the envelope is provided with a metallic or conductive part, the support wire, rod or tube being supported by the metallic or conductive part of the envelope.
