Abstract: 984, 567. Automatic voltage control of inverters. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Dec. 14,1961 [Jan. 5, 1961], No. 554/61. Heading G3R. [Also in Divisions H2 and H3] In an inverter circuit in which successive half-waves are generated by the conduction of controlled rectifiers TR1, TR3 the output is caused to follow a reference wave by causing the relevant controlled rectifier to be non-conducting when the output exceeds the reference wave and conducting when the reverse condition exists. During one half-cycle a semi-conductor controlled rectifier TR1 Fig. 4 is switched on by pulses from a pulse generator 12 Fig. 5 whenever the amplitude of the output waveform falls below that of a reference waveform supplied from 8 to an undisclosed comparator 9,and is switched off over capacitor C1 by the conduction of an auxiliary rectifier TR2, also controlled by the pulse generator 12 whenever the output waveform exceeds the reference. A gate circuit 10 then transfers control to a pulse generation 13 and rectifiers TR3, TR4 and the other halfcycle is similarly generated. The unwanted high frequency component is filtered from the resultant waveform.

Abstract: 1,124,521. Converting. ALLMANNA SVENSKA ELEKTRISKA A.B. 7 Jan., 1966 [9 Jan., 1965], No. 770/66. Heading H2F. A high voltage direct current power transmission system has two separate transmission lines 6, 7 and at least four converter stations 4, 5, 8, 9. Normally, each line connects two stations, and the two lines are not interconnected. If a fault occurs on one line the converters associated with that line are automatically blocked, reconnected to the other line and restarted. Before restarting, the voltage regulator of the first transferred station to be restarted is adjusted so that the no-load voltage of the station is less than the line voltage. Consequently the fault-free line is unaffected by the connection of this station. If the first transferred station to be restarted is an inverter, its current regulator is also adjusted so that it draws either zero current or a current less than the current margin in the fault-free line. The second transferred station may then be restarted without any adjustment of its regulators.

Abstract: 1514422 Diversity receivers MEL EQUIPMENT CO Ltd 12 Jan 1976 992/76 Heading H4L A radio system for an aircraft having front and rear antennae AF, AR, wherein a receiver Rx is cyclically switched between the aerials until a signal of a first standard of acceptability is received whence switching ceases until the signal coupled to the receiver decreases to a second, lower standard of acceptability additionally comprises means operative whenever an acceptable signal is being received and sensitive to the magnitude and sign of the line-of-sight component of the aircraft velocity relative to the transmitter to ensure that, provided the magnitude exceeds a given threshold value, the front, resp. rear, aerial is coupled to the receiver when the component is directed towards, resp. away from, the transmitter regardless of any previous selection made. It is thus ensured that antenna changeover occurs shortly after a closest approach to the transmitter has been made. The acceptability of the signal is assessed by monitoring the r.f. amplitude, the receiver a.g.c. signal, or the rate at which cyclically repeated messages are validated, to provide a signal Vs, antenna cyclic switching occurring under control of flip flop FF and oscillator OSC until the signal Vs, smoothed by network R 1  C 1 , is great enough to trigger threshold circuit (Schmidt trigger) Th 1 exhibiting hysteresis, to disenable the oscillator so that one of the antennae is selected, and to enable velocity threshold Th2 to receive the velocity component signal Vv. Time delay circuit TC2 ensures that, should fading occur, Th2 will continue to receive an input to enable holding of the selected antenna for a time dependent on the signal Vv strength prior to fading. The signal Vv may be derived by time differentiation of range measurements. The receiver Rx is associated with a transmitter Tx, both being coupled to the antennae via circulator T-R. The system is part of a landing and guidance system, position data being transmitted automatically or in response to interrogation.
