DEFINITION

Classification: 315/51

(under subclass 32) Subject matter, having a plurality of circuit elements structurally combined with the load device structure.

SEE OR SEARCH THIS CLASS, SUBCLASS:

33, for portable self-contained devices which include a source of potential and the other circuit elements necessary to operate the load device structure.

34, where one of the circuit elements is an antenna.

47, where the load device is a discharge device having a filament, electric heater or resistance in shunt to the discharge electrodes and an automatically operating electric switch is included in the shunt circuit.
