Abstract: A poly-phase rectifier assembly for an alternating current generator includes five heat sinks, three of which are compression spring-loaded to form series electrical circuits to the poly-phase stator windings. The other two sinks are separated by a crush-proof, phenolic type, insulating gasket, and carry a plurality of semiconductor button-type diodes. The stator sinks are cupped to position compression springs, and are slotted for heat transfer. The stator sinks extend above the slotted positive heat sink into the cooling air flow area. A second embodiment utilizes back-to-back diodes, compression spring-loaded into a positive heat sink and a negative heat sink. A cupped stator heat sink forms a nest and provides series connection for the stator poly-phase windings. A plastic assembly supports a capacitor.

Abstract: An electrical heating means for the bimetallic thermostatic spring controlling a carburetor automatic choke valve is in series with a negative temperature coefficient thermistor which senses engine temperature to open the choke valve in a more efficient manner and improve engine performance during warm-up. A temperature responsive switch is in series with the heater, negative temperature coefficient thermistor and a battery and senses engine block temperature to maintain current flowing in the heater after the engine is shut off and until the entire engine cools down, to provide better warm-engine restarts and reduce pollution.BACKGROUND OF THE INVENTIONThis invention is in the field of automatic choke valves for internal combustion engines and particularly to electrically controlled chokes.It is conventional in internal combustion engines to provide a carburetor having a choke valve therein controlled by a thermostatic spring whereby the choke valve is held closed when the engine is cold.
