Title: Improvements in or relating to automatic vehicle guidance systems
Inventor: GLASGOW JOHN ARTHUR
IPC: F41G7/00
Filed: 1968-08-20
Abstract: 1,273,985. Sonar homing device. MARCONI SOUNDING DEVICE CO. Ltd. 7 July, 1969 [20 Aug., 1968], No. 39711/68. Heading H4D. [Also in Division G4] Sonar guidance control apparatus for homing a water vehicle on to a target is adapted to cooperate with a target-illuminating transmitter not carried by the vehicle but transmitting pulses of frequency-modulated pressure waves and comprises means for receiving the waves directly from the transmitter and indirectly from the transmitter after reflection from the target, means for comparing the waveforms of the directly and indirectly received waves, and means for utilizing the indirectly received waves to effect vehicle guidance only if there is approximate similarity of the compared waveforms. The apparatus thus discriminates against random or deliberate interference waves. In the embodiment shown the vehicle is a torpedo carrying a receiver I for the direct pressure waves and a receiving transducer array E1 to E4 for the reflected waves. In known manner the array output signals are fed through amplifiers 1E1 to 2E4 and combining delay network L12, L34, K to provide on lines 3, 4 two signals whose difference (in amplitude and sign) is a function of the azimuth angle between the torpedo's heading and the incident direction of the reflected waves and to provide on lines 1, 2 two signals whose difference is a function of the elevational angle between the heading and the incident direction. These signals are fed to respective processing channels each comprising an amplifier EA, a sampling gate ES, a quantizer EQ (with two or more levels) and a shift register ESR. Receiver I output is fed via amplifier IA and sampling gate 3S to quantizer IQ, and when its amplitude exceeds background noise level, gates G1, G2 are opened by threshold circuit T to store the quantized receiver I output in shift register IR. The signals on lines 1, 2, 3, 4 are sampled simultaneously, quantized and stored in registers ESR, and the contents of registers ESR are then separately compared in comparators C4 with the contents of register IR. If the contents are similar the respective comparator gives a large output signal. A known azimuthal guidance system CHU is controlled in accordance with the difference between the output signals of comparators C3, C4 and a known elevational guidance system CVU is similarly controlled by the C1, C2 output signals.

Title: Apparatus for Measuring the Diameter of a Hot Bar.
Inventor: O'BRIEN FRANCIS EDWARD
IPC: B21B38/04
Filed: 1967-08-30
Abstract: 1,195,888. Measuring diameters of hot bars. UNITED STATES STEEL CORP. 30 Aug., 1967 [30 Aug., 1966], No. 39743/67. Heading G4H. Apparatus for measuring the diameter of a hot bar B (Fig. 1) includes an optical system scanning the bar connected to a photo-multiplier 34 which delivers an output pulse 60, the amplitude of which represents the temperature of the bar and the width of which represents its diameter. The apparatus includes a second photo-multiplier 34 connected to the optical system so that the first and second photomultipliers receive signals representing the scanning of the bar in opposite directions. The optical system preferably includes a disc 20 with four circular apertures co-operating with a rotatable slotted disc 28 and six slotted members 30, the slots being such that the bar is linearly scanned. A similar identical measuring system 37B may be placed at right-angles to the first. Diameter measurement.-After amplification the output pulses from the photo-multiplier are fed to Schmitt triggers 82 which enable gates 86 to pass clock pulses representing 0.002 inch increments from amplifiers 48, 50 (180 degrees out of phase) via a gate 194 (Fig. 2) to decade counter 158 (Fig. 3). The second decade B of counter 158 is connected to a reversible counter 160 (Fig. 2) which thus indicates the number of 0.02 inch increments. Temperature measurement.-The output of one of the photo-multipliers is fed to six Schmitt triggers 122, 124, 126, 128, 130, 132 (Fig. 3) which are calibrated to trip at varying voltages to give an output representing the temperature of the bar to within one of seven ranges. A matrix 134 decodes the range to binary form for storage in flip-flops 136, the outputs of which are converted into a signal on one of seven leads which is fed to a printer 142, a display 144A and a shrinkage selector switch 146. Shrinkage correction.-One of the fourteen positions of the rotary shrinkage selector switch 146 is selected in accordance with the material of which the bar is made so that, depending on the temperature of the bar, a signal on one of twenty leads is fed to a matrix 148 which converts this signal to binary form and feeds its complement with respect to 32 into a shrinkage counter 152 (Fig. 2). The signal fed to the matrix 144 represents the amount by which each 0.02 inch of diameter at the measured temperature shrinks on cooling. The shrinkage counter is then repeatedly counted up to 32, the counter 160 being decremented each time counter 152 is full until the count in counter 160 reaches zero when the count is terminated. The pulses fed to counter 152 are also fed to decade counter 158 so that the final count which is printed and displayed represents the measured diameter of the cooled bar.

Abstract: 899,918. Automatic speed control systems TOKYO SHIBAURA ELECTRIC CO. Ltd. Nov. 18, 1960 [Nov. 18, 1959], No. 39810/60. Drawings to Specification. Class 38 (4). Magnetic tape recording and reproducing apparatus for television signals comprises a tape having slanted parallel tracks recorded thereon by the video signals, and a magnetic head, other than the head for reproducing the video signals, travels across these tracks to provide signals for controlling the speed of the electric motor driving the tape. The head for controlling the speed is arranged so that its magnetic gap extends across each track, so producing a series of intermittent signals the repetition rate of which is dependent upon the speed of the tape. Thus, the speed of the tape is automatically controlled during reproduction so that the head for reproducing the video signals is brought into the proper positions with respect of the tracks. The speed-detecting head is made resonant at a predetermined low frequency which is determined by the ratio between the relative speed of the recording head with respect to the tape during recording and the desired speed of the tape during reproduction.

Abstract: 1,148,805. Digital transmission systems; multiplex pulse code signalling. FUJITSU Ltd. 6 Sept., 1966, No. 39875/66. Headings H4L and H4P. In a digital transmission system phasemodulated signals are transmitted, a frequency discriminator recovering the data at the receiver. In one embodiment return to zero (RZ) data in bipolar or unipolar form is converted to a differentially coded signal which feeds the modulator. By detecting the instantaneous frequency changes in the transmitted signal the discriminator develops a bipolar RZ signal. In a second embodiment the input bipolar RZ data is split between two channels, one carrying a signal representing the positive pulses in differential code and the other a signal representing the negative input pulses in differential code. These two signals phase modulate frequencies 90 degrees apart in phase, the resulting signals being combined to give a four-phase signal for transmission. The receiver discriminator develops a unipolar RZ signal. The input data may be time division multiplex pulse code modulation speech signals. Several systems according to the first embodiment may be combined in a frequency multiplex arrangement.

An A.C. driving system for a rail traction engine equipped with gas turbines 1, 2 driving an alternator 3 which supplies asynchronous traction motors 6 located on certain of the axles of the engine is provided with auxiliary means to start the gas turbines which means comprises an auxiliary generator 9 driven by a prime mover 8, the generator 9 producing a voltage at constant frequency which is fed to the traction motors 6 by way of a cyclic frequency converter 12. When starting, a control unit 5 is effective to switch the converter 12 on so that the output of the auxiliary generator 9 is fed through the frequency converter 12 to the motors 6 thus causing these motors to rotate. At the same time the alternator 3 will also function as a motor to rotate the turbines 1, 2 but no fuel is injected at this stage. A signal 13, responsive to the speed of the motors 6 is fed into the converter 12 such that the output frequency of the converter gradually increases, thus increasing the speed of the motors 6 and of the turbines 1, 2. At a given speed the turbines become effective to drive the alternator 3 to supply the traction motors 6 at which point signals dependent upon the alternator output voltage and current fed to the control unit 5 are effective to cause the unit 5 to switch off the converter 12 so disconnecting the starting generator 9 from the system. A resistor 15 is provided to supply non-regenerative braking for the engine and the generator 9 may be arranged to supply the auxiliary services on the engine by a supply lead 16.

Abstract: 1310868 Semi-conductor devices NATIONAL CASH REGISTER CO 7 Sept 1971 [29 Sept 1970] 41660/71 Heading H1K A charge coupled device consists of a semiductor substrate and a layer of insulation on one face having a series of alternately thick and thin regions between minority carrier injection and detection locations. The transfer electrodes, each consisting of a metal layer overlying adjacent thick and thin regions form two alternating groups supplied with oppositely phased pulse waveforms. As shown, Fig. 1, the series of regions is disposed within an etched channel in a much thicker layer 14 of silica, on which the conductive connections to the electrodes are located. The minority carrier injection may be effected, as shown, by an avalanche device consisting of a metal layer on thin insulation 35, by an electron beam, or by a PN or Schottky barrier on the N-type silicon substrate. Transferred minority carriers can also be detected by such a barrier. The thin regions under the transfer electrodes may be 800-1000 Š thick and the thick regions 100-500 Š thicker. In operation the pulses applied to the two groups of electrodes are of the same magnitude. Backward movement of the carriers is avoided because on account of the greater thickness of insulation the potential well beneath the leading edge of each transfer electrode is always shallower than that at the trailing edge.
