DEFINITION

Classification: 315/327

(under subclass 326) Systems wherein the discharge device is of the type wherein the discharge between the electrodes is initiated by bringing the electrodes into physical contact with each other and then separating the electrodes.

SEE OR SEARCH THIS CLASS, SUBCLASS:

263, and subclass 289, and indented subclass, for systems provided with an inductance or a surge generator in the circuit of the electrodes and designed to impress a high potential surge on the electrodes when the electrodes are separated from each other, after having been placed in physical contact.

291, and indented subclasses, for systems wherein means are provided for regulating the current in the supply circuit when the electrodes are placed in physical contact with each other.

357, for other movable electrode discharge device systems not of the discharge drawing type.

313, Electric Lamp and Discharge Devices, 146+, for discharge devices, per se, which are provided with movable electrodes (other than mere liquid electrodes) which may be brought into contact with each other, and subclasses 163+ for liquid electrode discharge devices (e.g., mercury arc lamps and rectifiers).

314, Electric Lamp and Discharge Devices: Consumable Electrodes, appropriate subclasses, for discharge devices of the consumable electrode type wherein the discharge is initiated by bringing the electrodes into physical contact with each other and then separating the electrodes, the discharge device being provided with means for feeding the electrodes together to compensate for the consumption of the electrode material during the discharge, and the circuits therefor. Class 314, Electric Lamp and Discharge Devices: Consumable Electrodes, includes carbon arc lamps and the circuits therefor.
