    摘要： A television tuner drive system includes a bidirectional electric motor coupled to a rotatable channel selector. A carryover cam and switch coupled to the motor causes the motor power to be decoupled at each broadcast channel position. A plurality of cams are supported by a rotating drum coupled to the channel selector and coact with a cam follower and single pole switch to override the carryover switch and maintain power coupling to the motor. The drum-supported cams are positionable to selectively coact or clear the cam follower permitting programming of channel stop positions.

    摘要： A rotary wiper contact supported on a hub is housed between a substrate having a resistive element and a bracket means to form a potentiometer subassembly. The bracket and substrate are fixedly mounted to a pushbutton tuner frame with the hub of the wiper contact directly mounted on the treadle bar for integral movement therewith. Actuation of any pushbutton or the manual tuning shaft to select a predetermined frequency rotates the treadle bar and the wiper contact varying the effective resistance of the potentiometer which controls the voltage of a varactor to tune the receiver.

    摘要： The present invention treats a push-button switch assembly with integral resistance which functions as a voltage divider having individually selectable and individually adjustable taps. The taps are selected by individual push-buttons. Individual adjusting knobs normally arranged behind each push-button provide for tap adjustment. The assembly is suitable for use in an electronically tuned television receiver wherein it provides both channel selection and fine tuning for a selected channel.

    摘要： A tuning device is disclosed for use in radio-frequency communication equipment, in particular television sets. Such a device includes a plurality of tuning units each comprising a push button contact for activating an associated tuning unit and a potentiometer, operatively connected to said push button, to permit selective tuning. Fine tuning is achieved in each tuning unit by an eccentric attached to a tuning spindle to operatively connect the potentiometer.
