Abstract: A logic circuit providing a bi-level signal, one level of which agrees with eriods of time during which the video signal corresponds to a quadrant of a first broadcast television program, said quadrant being free from horizontal and vertical synchronizing pulses present in the video signal of a second broadcast program.

Abstract: A blanking circuit for providing blanking pulses to a video system for a television receiver is disclosed. The blanking circuit is particularly adapted for fabrication in integrated circuit form and can advantageously be incorporated in an integrated circuit video processing system. The blanking circuit is adapted to receive retrace pulses of either polarity.

Abstract: A mount for a circuit breaker for mounting the circuit breaker in a holder of the type typically used for fuses and a method of making the mount is disclosed. Engaging means such as metallic screw threads or a bayonet ferrule are bonded to the envelope of the circuit breaker with one of the circuit breaker leads attached thereto. The other circuit breaker lead is attached to an eyelet. A spacer is molded between the base of the circuit breaker and the eyelet to hold the eyelet in a fixed position relative to the circuit breaker so that when the screw threads or bayonet ferrule is engaged with a holder, the eyelet contacts a contact in the base of the holder.

Abstract: A returnable shipping container includes top and bottom closure members each having inner indentations and an outer affixed metal member forming a peripheral slot with collapsible first and second body members formed to fit into the bottom and top slots and adjoining edges with aligned notches and tabs. A stabilizing insert fits into the indentations of the top and bottom closure members and the notches of the first and second body members.

Abstract: A circuit system for a television receiver, said system operating to repl a changing quadrant of the picture of a main transmitted program with an equivalent-size sector of a second transmitted program.

Abstract: A terminal connector having a strip carrying pressure fitted terminals is shown. Openings or notches between the lands carrying the pressure fitted terminals relieve stresses in the strip to reduce longitudinal extension and bowing of the strip.

Abstract: A fleshtone and tint correction detector DC coupled to at least two of the first, second, and third demodulator stages of a color television receiver provides a control signal in response to a shift in differential potential output from the demodulator stages to effect a shift in phase angle of reference signals applied in the demodulators whereby fleshtone and other color errors are reduced with a minimum deleterious effect on other colors.

Abstract: A protection circuit for a television receiver which disables the television receiver by disabling the horizontal deflection circuit in response to fault conditions is shown. The protection circuit detects excessive current drain by a low voltage supply, excessive current drain by a high voltage supply, and excessive high voltage. In response to any one of these fault conditions, the horizontal deflection circuit is disabled.

Abstract: A noise suppression circuit for suppressing or cancelling noise pulses in a composite video signal coupled to television receiver synchronizing pulse separator and automatic gain control circuits is shown. Noise pulses in the video signal exceeding the amplitude of the synchronizing pulses are detected. The detected noise pulses are direct current coupled to the synchronizing pulse separator circuit and alternating current coupled to the automatic gain control circuit to inhibit hang-up of the automatic gain control system. The reference level for detecting the noise pulses is gated to inhibit detection of synchronizing pulses. The noise detecting reference level is also derived from the automatic gain control reference level.

Abstract: A locking mechanism, and opening mechanism, particularly of the type used on doors of automotive vehicles, which comprises an actuating rod attached to an opening lever as well as to a key cylinder and activated by use of a key employed to turn said cylinder.

Abstract: A method for removing and replacing a portion of the sealed top of a defective plastic-cased automotive or marine battery for the purpose of repair of defective cell or cell-connectors.
