    Abstract: Input signal current combined with a substantially constant direct current bias is coupled to the junction of the emitter electrode of a transistor biased in common base configuration and one electrode of a diode poled similarly to the base-emitter junction of the transistor. A variable direct current supply is coupled to the other electrode of the diode. The collector of the transistor provides an output signal current, the average value of which is complementary to the average current flow through the diode. An electrically controlled attenuator is thus provided. This attenuator mechanism can be used to regulate a reactive current flow in phase shift circuitry to afford electrically controlled phase shift networks. Such electrically controlled attenuation and phase shift circuitry is well suited for use in remotely controlled television receivers and lends itself to monolithic integrated circuit construction.

    Abstract: A remote-controlled television receiver includes a VHF and a UHF tuner each having tunable resonant circuits which are adjusted by the gear train of a remotely controlled motor. The tuners are connected so that during UHF operation the VHF tuner provides amplification of the UHF tuner IF signal output. A relay switch is operatively connected to the VHF motor to control the motor energization. Switch means are coupled to the VHF tuner motor gear train and provide an indication when the VHF tuner is adjusted for amplification of the UHF tuner IF signal output. A bistable multivibrator is coupled to the switch means in a manner so that the multivibrator changes states in response to the switch indication. A relay winding current control means responds to the change in state to prevent current from flowing into the relay winding. This causes the relay switch to open and deenergizes the VHF motor. A second relay switch is operatively connected to the UHF motor to control the motor energization. A second relay current control means is connected to permit a flow of current through the second relay winding only when the switch indication is present.

    Abstract: A controllable shunt current path such as the conducting emitter-to-collector path of a first transistor, is connected in shunt with the emitter-to-base path of a conducting output transistor. In response to a turnoff signal for the output transistor, the first transistor is caused to conduct more heavily in a direction to stop forward conduction of the emitterto-base diode of the output transistor and in this way to speed up its turnoff. Other features of the circuits illustrated include overload current protection and means for speeding up the discharge of any charge present at an output terminal upon switching of an output transistor from a nonconducting to a conducting condition. One of the circuits illustrated also includes means for ensuring proper sharing of current drive to a pair of transistors and means for ensuring ''''soft'''' saturation of the output transistor.

    Abstract: A compact, easily tunable, silicon avalanche diode oscillator for pulsed operation in the L-band which has an efficiency of about 40 percent, equal to that of vacuum tube oscillators operating at these frequencies, is obtained by utilizing a coaxial line composed of three serially connected sections in which the intermediate section has a characteristic impedance significantly larger than either of the other sections. One end of the coaxial line is short circuited; the avalanche diode is coupled to the coaxial line at a point between the short circuit and the beginning of the intermediate section; a variable capacitance is connected across the intermediate section at a given point thereof; and the other end of the coaxial line is connected to the output of the oscillator. The short circuit is made movable with respect to the position of the avalanche diode and the variable capacitance is made adjustable.

    Abstract: In a motion picture record in which successive frames of a motion picture are manifested by a series of successive holograms, such as phase holograms, greater redundancy and a saving in record material are achieved by having each one of the holograms partially overlap both the hologram which immediately precedes and the hologram which immediately succeeds that hologram in the series. The problem of unwanted spatial beat frequencies, which results from such overlap and is dependent on the amount of such overlap, can be eliminated by restricting the amount of overlap to a value such that the minimum spatial beat frequency is less than the ultimate resolution of the playback system (e.g. closed circuit television) employed in reconstructing the motion picture from the motion picture record.
