A clutch assembly includes a shaft, vent plug and oil guide sleeve. The present invention has the leaf spring connected at least sectionally to a metal layer to form a Schottky contact, and an electrical voltage or field source is provided, which generates an electrical AC voltage a vicinity or area of the Schottky contact. The air under pressure passes through radiator and fills accumulation tank waiting to be used, while the oil deposited at the bottom of the separator, is picked up by conduit and passes through radiator to be brought again to compressor. identical source and receiver patterns, identical locations, and the source orientations have to be identical to the receiver components. In addition, a body member to be located may be illuminated from one side and the location of the illuminator detected by a probe on the other side of the body member. The heating member may be silicone rubber containing resistance heating elements, and its temperature may be regulated by a suitable temperature control, such as a thermostat or other means.
