Abstract: A rechargeable battery provides a source of operating potential for an electronic circuit load. An operator controlled on-off switch connects the battery to a relay, and through the normally open relay contacts, to the electronic circuit. The relay winding is returned to ground through a capacitor. When the switch is closed the relay is momentarily energized by the current which charges the capacitor. A transistor has its collector-emitter path in parallel with the capacitor and its base coupled to the movable tap on a voltage divider connected across the load. In the absence of a low voltage condition across the load, the transistor conducts maintaining relay closure for normal circuit operation.

Abstract: A pair of television receiver high voltage connectors, connecting the receiver high voltage rectifier to the cathode ray tube anode lead and the high voltage transformer, each include a resilient sleeve in which a cup-shaped contact and insulated wire together with an axially compressible spring are supported within a receptacle, formed by a portion of the sleeve inner surface and the cup-shaped connector. The receptacle expands to accommodate the insertion of the end portion of the high voltage rectifier forming an air-tight enclosure for the connection which is completed by the compression of the spring between the contact and rectifier.
