(under subclass 296) Discharge devices which have either a plurality of separate cathodes or a plurality of separate nonemissive electrodes (e.g., anodes) in addition to the interposed apertured or grid-like electrodes so that the discharge device has at least two separate inter-electrode spaces.
(1) Note. In the discharge devices in this subclass there may be a plurality of apertured or grid-like electrodes in one of the inter-electrode spaces, the apertured or grid-like electrodes being in nonsuperimposed relation, or there may be only one apertured or grid-like electrode in each of the inter-electrode spaces.
SEE OR SEARCH THIS CLASS, SUBCLASS:
6, for plural unit discharge devices which have at least two cathodes and a separate anode for each cathode there being an apertured or grid-like electrode interposed in the discharge space between each anode and cathode.
239+, and 245, for discharge devices which include significant supporting and/or spacing structure for a plurality of discharge electrodes which form a plurality of separate inter-electrode discharge spaces. See subclasses 239+ where the device includes supporting and/or spacing structure for a shield member which is interposed between two of the separate discharge spaces.
245, see the reference to subclass 239 above. 296, for discharge devices having only one inter-electrode discharge space and which have a plurality of apertured or grid-like electrodes in the inter-electrode discharge space in nonsuperimposed relation.
298, where at least one of the inter-electrode spaces contains a plurality of apertured or grid-like electrodes in superimposed relation with respect to each other.
302, and 303, for discharge devices having a plurality of inter-electrode spaces, an apertured or grid-like electrode being interposed in only one of the inter-electrode spaces. See subclass 302 where the discharge device has a plurality of cathodes, and subclass 303 where the discharge device has a plurality of nonemissive electrodes (e.g., anodes).
597+, where the discharge device has an envelope containing a gas or vapor.
