DEFINITION

Classification: 313/614

With anode shield:

(under subclass 613) Subject matter wherein the electrode is an anode or the electrode acts as an anode during the portion of an alternating voltage supplying power to the electrode and the member prevents bombardment of the anode or electrode by positive ions or restricts the area of the anode or electrode available to the discharge of the device.

168, for liquid electrode discharge device which has a plurality of anodes and an envelope having a plurality of separate anode chambers.

169, for a liquid electrode discharge device which is provided with a plurality of anodes, at least one anode having a shield.

590, for three or more electrode gas or vapor discharge device including a plurality of anodes, at least one anode having a shield.

609+, for a gas or vapor discharge device having physical barrier or partition between the electrodes of a discharge path to cause the discharge to travel along a longer path between the electrodes or a constricting means in the discharge path which reduces the cross-sectional area of the discharge path to a smaller area than the rest of the path.

616, for a gas or vapor discharge device with a positive ion or cathode shield.
