DEFINITION

Classification: 313/244

(under subclass 243) Discharge devices in which the device is enclosed within an envelope, the electrodes being supported by or forming part of the enclosing envelope.

(1) Note. The electrodes need not be supported directly upon the envelope, but may be supported upon support rods or other support members which are supported by the enclosing envelope.

SEE OR SEARCH THIS CLASS, SUBCLASS:

239+, where the discharge device also includes supporting and/or spacing structure for a shield.

283, and the subclasses specified in the notes thereto for other devices under the class definition which include an envelope and an electrode, the electrode being supported by the envelope.
