.~.~ Automatic cut-out or voltage regulator for the heater circuit
DEFINITION
Classification: 315/116
(under subclass 115) Systems provided with (1) means to open the current supply circuit for the heating means, or (2) means to regulate the current supplied to the heating means, such means being automatically operated in response to some condition.
(1) Note. The condition causing the opening of the heater circuit or the operation of the regulating means may be (1) when the load device current and/or voltage becomes too high or too low, or (2) the temperature of the load device, or (3) any other condition affecting the operation of the load device.
SEE OR SEARCH THIS CLASS, SUBCLASS:
106, and 109, for systems provided with a discharge device load device of the type having either a thermionic cathode designed to be heated by the flow of current there through or an indirectly heated cathode, the system including an automatic cutout or voltage regulator in the cathode or cathode heater current supply circuit.
114, for this subject matter where there are a plurality of load devices in the system.
117, for systems under subclass 112 provided with means other than electric heating means for modifying the temperature of the load device, such temperature modifying means being automatically controlled in response to some condition affecting the operation of the load device.
119, and indented subclasses, for systems provided with an automatic cutout for the load device. 307, and indented subclasses, for systems provided with automatic regulating means to regulate the supply of current to the load device.
