DEFINITION

Classification: 315/344

(under subclass 326) Systems wherein an electromagnet is placed adjacent the interelectrode discharge space so that the space discharge is influenced by the magnetic flux.

SEE OR SEARCH THIS CLASS, SUBCLASS:

42, for discharge devices having structurally combined therewith an inductive impedance which is connected between either a plurality of anodes or a plurality of cathodes of the discharge device, the discharge device being provided with an electromagnet for influencing the discharge between the electrodes.

236, for this subject matter where there is a condenser in the supply circuit of the discharge device.

267, for this subject matter where the discharge device is supplied with pulsating or alternating current.

338, for this subject matter where the discharge device is provided with two or more cathodes and/or two or more anodes.

342, for this subject matter where the discharge device is provided with a plurality of different control means, one of which is an electromagnet. 343, for this subject matter where there are a plurality of electromagnets for influencing the discharge.
