Abstract: 1357753 Track apparatus BRITISH RAILWAYS BOARD 22 June 1972 [29 June 1971] 30463/71 Heading B7N [Also in Division H4] In a system for communicating with a vehicle moving along a track, as described, a railway track, in which a loop 10 terminated by its characteristic impedance 14, Fig. 2, and energized by a transmitter 12, extends along the track 11, an additional multi-turn loop 13 is connected in series with the loop 10 at one end thereof. The vehicle is provided with means to pick up both the magnetic and the electric fields produced by the signal flowing in the loop and the loop 13 is arranged to suppress the electric field to provide an indication of the end of the loop 10. To suppress the electric field the coil 13 is wound inside a metallic tube which does not form a complete circuit so that the magnetic field is not screened. Fig. 3 shows the variation of the magnetic field M and the electric field E with distance along the loop 10 when the vehicle is travelling in the direction A, Fig. 2, the magnetic field produced by the coil 13 in the region x showing a distinct peak whilst the strength of the electric field falls. Fig. 4 shows a circuit carried by the vehicle which senses the orientation of the loop and allows or suppresses the generation of an "end of section" signal according to the direction of vehicle motion. The electric field picked up by a capacitive probe 16 supplies a threshold detector 17 giving an output whenever the input exceeds E1, this output being supplied via an OR gate 20 to an AND gate 21. The magnetic field is picked up by a coil 15 and supplied to threshold detectors 18, 19 providing outputs when the signal exceeds Ml and M2 respectively. The output of detector 18 provides the other input to AND gate 21 which via OR gate 20 continues to provide an output as long as there is an output from detector 18.

Title: Improvements in and relating to electric control apparatus
Inventor: ALSOP CHARLES FRANCIS
IPC: G05D3/14
Filed: 1960-09-06
Abstract: 1,004,851. Diode switching circuits. ENGLISH ELECTRIC CO. Ltd. Sept. 6, 1961 [Sept. 6, 1960], No. 30728/60. Heading H3P. A control circuit for producing an output in dependence on the magnitudes of one or other of two related D.C. voltage input signals, comprises a constant current network 10 across which are connected two switching circuits 15, 16 each comprising a constant voltage device, e.g. a Zener diode 17, 18, a rectifier bridge circuit 19, 20 and an input circuit 30, 31, respectively. The constant current network is arranged so as to provide a current equal to that in the input circuit 31 at a required changeover value (equal to the maximum voltage input signal applied by circuit 31 to the bridge 20) and the constant voltage device 17 is such that the circuit 15 only passes current when the current in the input circuit 30 reaches the changeover value. The Zener voltage of diode 18 is chosen to be lower than that of diode 17 and slightly lower than that of the output voltage of the constant current circuit 10, so under normal conditions, this diode 18 conducts giving a low impedance between terminals 20a. Current from a " fine " error input 25 thus flows through winding 29 of a magnetic amplifier 27. When the fine error signal has increased to its maximum value, i.e. the point where it produces a current in circuit 31 equal to that supplied by the constant current source, no further current increase is possible in winding 29. The circuit is arranged so that at this point the " coarse " error input 23 has risen sufficiently to cause diode 17 to conduct to produce a low impedance between terminals 19a allowing current to flow through winding 28. The consequential reduction in voltage across diode 18 then cuts it off so that the output is dependent on the " coarse " signal only. During the transition of control from fine to coarse the control currents in the windings 28, 29 are additive so as to give a smooth output signal during the change-over. A by-pass circuit 34 may be added across terminals 19b to provide an alternative low resistance path for the flow of " coarse " current when this increases above the value at which network 19 blocks. The input signals are derived from syncros 23, 25 in a control system.

Abstract: 1473353 Coherent pulse radars INTERNATIONAL STANDARD ELECTRIC CORP 12 July 1974 [12 July 1973] 30998/74 Heading H4D In a coherent pulse radar employing a microwave transmitting tube, e.g. a magnetron from which an R.F. pulse is not assured for a given trigger, any resulting missing TX pulse is detected, and a signal is supplied to a selector circuit, which is thus arranged to pass the normally received, sampled and coded signal, except where a missing pulse is detected, in which case a substitute signal, generated in a circuit which determines the probable value of the signal for the repetition period in question from the value of preceding received signals, is outputted from the selector circuit. Clock circuit 22 produces clock pulses H. These are applied to circuit 5 which generates radar transmission synchronizing signals Sy, which are applied to TX modulator 4 and also to circuit 14 which detects any microwave pulses absent from the output of magnetron transmitter 3. The receiver channel comprises two mixers 6 and 8, connected to L.O. 7, and respectively receiving echo signals from circulator 2 and part of the transmitted microwave signal via a directional coupler. Mixer 8 output feeds both a coherent oscillator 9, which supplies a referenced phase signal to phase detector 10, and an I.F. amplifier 17. This I.F. signal is detected at 18, the output of which being fed to one input of AND gate 16. Signals Sy are fed via monostable 15 which lengthens them to allow for phase shift through 4 and 5 to the other input of AND gate 16. Flip-flop 19 is connected so that its set input is fed by AND gate 16 and its reset input by signals Sy. A signal appears at its 0 output when detector 18 fails to detect a microwave pulse. This signal is applied to selector circuit 13. The echo signals detected by phase detector 10 are sampled at 11 and encoded at 12. Memory circuit 20 of the type described in Specifications 1,113,022, 1,132,284 and 1,192,436, receives the coded samples and stores the samples for the preceding two repetition periods a and b. Circuit 21 computes the probable value of the sample c for each repetition period according to the relation: c = 2b - a. When circuit 14 detects a missing TX pulse, selector circuit 13 switches to pass the sample computed in circuit 21. It is stated that the circuitry may be duplicated to process the received signals in quadrature.
