Abstract: A protection circuit is disclosed to protect circuitry inside an integrated circuit from damage due to high voltage transients. The protection circuit comprises a PNPN structure forming a silicon controlled rectifier (SCR) and a resistive element integral to the SCR structure. The SCR and the resistive element are arranged to form a two terminal protection circuit which is rendered conductive when the potential difference across the two terminals is greater than one forward biased PN junction voltage drop. In one embodiment the resistive element is a linear resistor and in another embodiment is a non-linear resistor in the form of a diode connected transistor.

Abstract: An AGC system is provided which develops controllably delayed gain control signals of opposite sense for an intermediate frequency amplifier arrangement. One gain control current is applied to the collector of an output transistor. The collector of the transistor is coupled to its base by a network which includes a filter for removing signal frequency noise from the gain control signal developed at the emitter of the transistor.

Abstract: A record support and alignment apparatus comprises a set of lifting pads secured to a depressible platform mounted in a video disc player. The lifting pads are adapted for motion between a withdrawn position and an extended position with respect to the platform. The lifting pads, in the withdrawn position, allow a record jacket to be fully inserted into the player. The lifting pads, in the extended position, support a record retained in the player such that the retained record is aligned with an empty jacket during its insertion in the player.

Abstract: In a PAL color television system for processing a color signal including burst and chrominance components alternating in phase at the image line scanning rate, identification and control circuitry for rapidly correcting an incorrect mode of line to line color demodulator switching. A bistable circuit generates timing signals for controlling line by line switching of a selected color demodulator(e. g., R-Y). An identification signal representative of an incorrect line switching mode is derived from information contained in the burst component, and serves to reset the bistable circuit such that timing signals corresponding to a correct switching mode are produced.
