Patent GB-1289674-A (GB)
IPC: H02P9/14
Filed: 1970-01-08
Abstract: 1289674 Automatic voltage control WESTING HOUSE BRAKE & SIGNAL CO Ltd 19 April 1971 [8 Jan 1970] 988/70 Heading G3R [Also in Division G1] A circuit arrangement to provide the voltage regulator of a polyphase supply with a signal representative of the output voltage of the supply comprises three transformers having starconnected primary windings 1, 2, 3 respectively receiving the phase voltages R Y B of the supply, star-connected secondary windings 4, 5, 6 portions of whose outputs are respectively applied to squaring circuits 10, 11, 12 via potentiometers 7, 8, 9, and a circuit 13 which sums the outputs of circuits 10, 11, 12 and produces, across the terminals 14, a unidirectional squared voltage signal for application to the regulator. The latter may control the excitation of an alternator or a three phase inverter. A discussion is given of the conditions necessary to ensure that the signal at terminals 14 is always proportional to the true RMS voltage of the supply. The first condition is that the voltages applied to the circuits 10, 11, 12 should be substantially balanced and the potentiometers 7, 8, 9 are adjusted to produce this condition. Secondly, unbalance caused by the power factor of the load on the supply is compensated by injecting, via links 17, 18, 19, quadrature voltage signals proportional to the out of phase component of each phase current. Thirdly, harmonics are reduced by series-connected tertiary windings 21, 22, 23 which enable the star point to "rotate" at harmonic frequencies and which also help to reduce voltage unbalance. Additionally capacitors may be connected across the windings 21, 22, 23 to shunt harmonics away from the squarer circuit, which have a very short time constant and negligible amplitude and phase distortion. The third harmonic may be eliminated by employing a second group of transformers whose secondary windings are connected, in a phase-displaced manner, to appropriate ones of the windings 4, 5, 6, so that the third harmonic voltages are anti-phase and the fundamental voltages are vectorially additive. The primary star points of the two transformer groups are connected together.

Abstract: 1295189 Alarm systems TELEFONAKTIEBOLAGET L M ERICSSON 30 Dec 1970 [8 Jan 1970] 61894/70 Heading G4H A control signal G, e.g. a random pulse sequence is transmitted through successive protected units B1-Bn connected in a loop a with the control station C, each unit B modifies the signal supplied to it over loop a, e.g. by an exclusive OR gate E11-E1n and a characteristic pulse sequence generator G11-G1n, and the control station compares the returned signal with the original control signal. A modifying unit SK may effect the same signal changes as those normally effected by units B so that a comparator K signals an alarm if inequality is detected, while comparators K1-Kn which receive the return signal additionally modified by a respective generator G31-G3n and gate E31-E3n corresponding to G11-G1n and E11-E1n identify the alarm-signalling unit B if equality is detected. In an alternative arrangement, modifier SK is placed between the return line and comparator K and effects the opposite modifications to those normally effected in units B.

If there are N aerials in the array, a pulse of length NT is applied to counters 26, 27 which respectively count the number of zero crossings (of the signal train) occurring during pulse NT and measure the time lapse between the first and last such zero crossings, the latter measurement being supplied to counter 26 to produce an output representative of the frequency of the signal train during pulse NT: that frequency is representative of bearing (and/or elevation). The invention is applied to a system, Fig. 1, in which an aircraft is to be informed of its position relative to a ground (or other) station at which a transmitter 1 and the inventive directionfinder are located. Transmitter 1 emits coded signals and when analyser 5 on the aircraft shows that the code particular to that aircraft has been received, aircraft transmitter 6 emits a c.w. signal for a predetermined time period. The direction-finder output is transmitted by transmitter 1 and displayed in the aircraft. Two direction-finders are provided, one for azimuthal and the other for elevational determinations. A ranging device may be added, utilizing the time delay between coded emission from transmitter 1 and reception of the signal emitted by transmitter 6 at array 8. An array may typically have a hundred aerials.
