DEFINITION

Classification: 313/255

(under subclass 253) Discharge devices which have the support wire, rod or tube which supports an electrode supported by a plurality of spaced or opposed parts of the envelope, or which have an electrode supported by a plurality of support wires, rods or tubes, different ones of the support wires, rods or tubes being supported by different opposed or spaced parts of the envelope.

(1) Note. This subclass provides for the patents for the discharge devices where the support structure for a plurality of electrodes is claimed, at least one electrode being supported by a support wire, rod or tube which is supported by opposed or spaced parts of the envelope. Where the discharge device has one electrode supported by support wires, rods or tubes which are supported by only one portion of the envelope, and another electrode supported by support wires, rods or tubes which are supported only by an opposed or spaced part of the envelope, the patent will be classified in subclass 253 or subclass 254.

247, where the envelope wall includes a hollow conductive part which is designed for use as an electrode, another electrode being supported by means of one or more support wires, rods or tubes which are supported by the opposed end closures of the hollow electrode.
