135.~ Discharge device and/or rectifier in the signal circuit


DEFINITION

Classification: 315/135

(under subclass 129) Systems provided with a discharge device or rectifier connected in the circuit of the signal, indicator or alarm means, the signal, indicator or alarm means being controlled by the current flowing through the discharge device or the rectifier.

(1) Note. Where the discharge device in the signal, indicator, or alarm means circuit is of the type defined in the class definition as being included as a load device in

this class, the patent is classified as a plural load device system in subclass 130 and indented subclasses above even though the discharge device is not disclosed or claimed as anything more than a means for controlling the current flow to the signal, indicator, or alarm means.

SEE OR SEARCH THIS CLASS, SUBCLASS:

200, and indented subclasses, for systems provided with a discharge device or rectifier connected either in electrical series relation or electrical shunt relation to the load device and the source of current supply for the load device.
