326  DF  DISCHARGE DEVICE LOAD {8}
340.~ With de-ionizing means in the cathode-anode circuit


DEFINITION

Classification: 315/340

(under subclass 326) Systems having means in the cathode-anode circuit for interrupting or extinguishing the flow of electric discharge current between the cathode and anode.

(1) Note. The search should be continued in the appropriate subclasses above for systems where the space discharge device is provided with current of a particular character and means are provided for interrupting the flow of interelectrode discharge current. For example, search subclass 261 and indented subclasses, subclass 268 and indented subclasses, where the discharge device is supplied with alternating current and a discharge control means is provided for the discharge device, the discharge being extinguished by the alternating current in each cycle of the alternating current wave, and the discharge controlling means being operative either to permit the discharge to be formed or to suppress the discharge on the succeeding cycle.
