DEFINITION

Classification: 315/334

(under subclass 326) Systems wherein the discharge device is provided with two or more cathodes and/or two or more anodes.

SEE OR SEARCH THIS CLASS, SUBCLASS:

42, where the discharge device has structurally combined therewith an inductance which is connected between either a plurality of anodes, or a plurality of cathodes.

60, where the discharge device includes an auxiliary starting electrode and an impedance is structurally combined with the discharge device structure and connected to the auxiliary starting electrode.

84.61, for plural cathode or anode tubes utilized in storing systems.

109, where the discharge device is provided with an auxiliary electrode, the auxiliary electrode being included in a circuit which controls the operation of a gas or vapor

replenishing means for the discharge device. 124, where the discharge device includes an auxiliary electrode which controls the operation of a shunt circuit closing means or a cutout means for isolating the discharge device from the supply source when the discharge fails to operate properly.

145, and subclass 147 and indented subclasses, where the discharge device is supplied with polyphase alternating current.

167, and indented subclasses, where there are a plurality of sources of current supply for the discharge device.

202, and indented subclasses, where the supply circuit includes an electric space discharge device.

233, and indented subclasses, where the supply circuit includes a condenser.

260, and indented subclasses, where the source of supply is a pulsating and/or alternating current.

330, and indented subclasses, where the discharge device is provided with an auxiliary starting electrode which is brought into contact with one of the principal electrodes to initiate the discharge.
