Abstract: A gating circuit for a deflection system which includes a first switch which is coupled to a deflection winding for supplying energy to the deflection winding during a trace interval of each deflection cycle. A commutating network including a second switch is coupled to the deflection winding and supplies energy to the deflection winding during a commutating interval of each deflection cycle. A coupling network couples a first polarity portion of gating signals developed by the commutating network to the first switch during the trace interval to enable conduction of the first switch. The coupling network also provides a second polarity portion of the gating signals to the first switch during the commutating interval to enable the turn off of the first switch.

Abstract: A circuit for correcting vertical deflection distortion of an image displayed by a cathode ray tube is composed of first, second, third, fourth, fifth and sixth transistors, a common load connected to output electrodes or collectors of the first and fourth transistors and a variable DC source connected to a control electrode or base of the sixth transistor. A saw-tooth signal having the vertical deflection frequency is applied to a control electrode or base of the third transistor, and the first and firth transistors and the second and fourth transistors are differentially switched at a rate corresponding to the horizontal deflection frequency so as to obtain from the load a signal for correcting vertical pincushion distortion.

Abstract: Side, or left and right pin-cushion distortions in the raster of a cathode ray tube, for example, of a color television receiver having an in-line arrangement of its electron beams, are corrected by connecting the horizontal deflection winding of the cathode ray tube, the collector-emitter path of a transistor and the output winding of a saturable reactor, in series, to a power supply source, and by applying to the base or control electrode of the transistor and to the input winding of the saturable reactor a correction signal having a parabolic waveform of the vertical scanning rate or frequency so that correction of the side pin-cushion distortions is effected satisfactorily at all portions of the raster.

Abstract: A seawater battery comprises a plurality of bipolar electrodes. Each bipolar electrode includes an anode and a cathode attached to the alternate sides of a barrier. The barrier is a sheet of thin flexible plastic material. The edges of the barrier extend beyond the edges of the anode and cathode. Opposing edges of the barrier are folded against the opposing edges of the anode so as to form flanges. A suitable number of the bipolar electrodes, along with suitable endwalls and end electrodes, are assembled so that the flanges of any particular bipolar electrode overlap the flanges of an adjacent barrier. An adhesive tape is wrapped around the assembly sealing the several edges of the barriers, including the flanges, and holding the bipolar electrodes in place. Alternately, a hot melt may be used to seal some or all of the battery edges. Because the barriers are very thin, the battery is compact and economical of space. Further, it is economical to construct.

Information for the automatic switching is obtained by continuously monitoring the yoke voltage, the power supply voltage being switched to a voltage of higher magnitude when the yoke voltage exceeds a predetermined level and returned to the power supply voltage of lower magnitude when the higher magnitude voltage is no longer required.

Abstract: A traffic-surveillance system comprises a radar equipment coupled to a transmitter/receiver antenna. This antenna is formed by a transmission line including an elongate hollow conductor with leakage losses, such as a slotted coaxial cable or waveguide, producing along its length an electric radiating field. Any metallic mass, such as a vehicle, located within that field reflects part of the radiated energy which is then picked up by the line. Part of the reflected energy is absorbed in the characteristic impedance of the line while the remainder is conveyed to the radar equipment where it is processed to yield the required information concerning the vehicle.

Abstract: A radar return signal is analyzed by amplitude comparators so as to classify the radar return signal with respect to 2.sup.n -1 threshold levels to thus produce n parallel bits for each classification defining the instantaneous amplitude of the radar return signal. The bits in a given significant bit position (most significant, least significant, etc.) comprise a word which moves through the video storage device serially with respect to bits in the same significant bit position and in parallel with respect to bits in the word comprised of different significance bits. Input buffers in the form of n storage registers are provided, each storage register being associated with a particular bit significance. The bits are entered into their associated storage register at a rate dependent upon the desired radar range. The bits are optionally integrated on a bit-by-bit basis and then entered into a main memory having n circulating storage registers arranged in parallel.

Abstract: A Multicell seawater battery is provided with a top venting means. The venting means comprises a series of passages each located above and communicating with a particular cell. The several passages are connected by ports alternately at one end and at the other end of the cells to form a zig-zag conduit at the top of the battery. A similar passage may be located at the bottom of the battery. The improved porting reduces electrical losses to ground and also reduces the background noise of the battery.
