Title: Position Control Apparatus
Inventor: AOKI TAKAOMI
IPC: G05B19/35
Filed: 1967-11-07
Abstract: 1,192,426. Programmed control of movement. TOKYO SHIBAURA ELECTRIC CO. Ltd. Nov. 7, 1967 [Nov.7, 1966], No. 50550/67. Heading G3N. A positional control system, responsive to command information, a signal corresponding to the command information is derived from a device incorporating a plurality of operational amplifiers each provided with a plurality of weighting resistors selected in dependence in the command information. As shown, a device 11, responsive to a tape or card, memorises and issues commands to a oscillator 12, which issues a train of pulses representative of an incremental movement of a member 19, and a command B to a vector generator 14 indicative of a desired direction of movement, and command travel information into a subtraction counter 15. The counter 15 is counted down by the pulses from the oscillator 12 and at zero count a gate 13 is closed to stop the supply of pulses to the vector generator. The vector generator 14, Fig. 2 (not shown) comprises a reversible counter, into which the incremental command is fed in accordance with the command B, a converter circuit whereby a plurality of gates are selectively opened or closed in accordance with the number in the counter. The gates selectively connect input resistors to two operational amplifiers, the resistors being supplied from a sine wave oscillator, with an associated inverter. The outputs from the amplifiers are fed to the sine and cosine windings of a resolver pick-up device 16. The resultant of the magnetic flux due to the energization of the winding is stepped by equal angular increments to the position representative of the incremental command. The rotor of the resolver is mechanically driven by the member 19 and the error signal induced is brought to a null value by a conventional servo system comprising a servo amplifier 17, a driving device 18 and a feed-back tachogenerator 20. The presence of a null error voltage from the pick-up, indicative of the member 19 reaching the desired position, and of a zero voltage from the tachogenerator 20, indicative of movement having ceased, are determined by sensor circuits 21, 20 the output signals of which, together with a signal, indicative of the counter circuit 15 being empty, through a gate 23 initiates stepping of the command device 11 and, through a line F, the operation of auxiliary equipment.

Abstract: 1,241,295. Automatic power control. PLESSEY CO. Ltd. Oct.25, 1968 [Nov. 13, 1967], No. 51634/67. Heading G3R. The power dissipated by an A.C. load 12 is controlled by an arrangement including pulse producing means, e.g. a saturable reactor 1, which produces pulses at the start and finish of each half-cycle of an alternating current supplied to the load 12 through a uni-directional switch, e.g. a thyristor 10; each pulse is dropped across the series combination of a reference impedance, e.g. a fixed resistor 7, and a variable detector impedance, e.g. a thermistor 8, responsive to the power dissipated in the load, the voltage at the junction 9 between impedances 7, 8 being effective for triggering the switch 10. The pulse-producing windings 5, 6 of the saturable reactor 1 are connected in a bridge circuit with the impedances 7 and 8 so that the voltage at 9 is zero when the thermistor 8 is at the correct temperature ccrresponding to the desired load dissipation. Should the load dissipation vary, the impedance of thermistor 8 will vary accordingly and the resultant voltage pulse at 9 will control the firing of thyristor 10 to correct the deviation.

Title: Data terminals
IPC: H04L25/02
Filed: 1971-11-17
Abstract: 1410921 Digital transmissions; synchronizing arrangements GENERAL ELECTRIC CO Ltd 10 Nov 1972 [17 Nov 1971] 53380/71 Heading H4P A synchronizing arrangement for a receiver terminal has a timing generator having a cycle of slots = number of digits per character which divides incoming data into characters. The generator is reset in response to a command signal derived from a sync. indication device. The timing generator may be halted in response to the command signal and restarted at a predetermined point from the indication device. Alternatively the timing generator may be reset to a determined point without halting it in its cycle on occurrence of the next sync. indication following the command signal. An indication, e.g..printed read out of the sync. misalignment may be given. Each character includes a check, e.g. parity portion which is correlated to the message portion and absence of correlation is stored and provides a read out also may reset the timing generator. The parity check may have an incorrect parity bit inserted in order to test the equipment. Indication of sync. may be produced on recognizing a predetermined pattern of bits in at least some characters but preferably successive characters; each character may have eight parity bits correlated to twenty message bits. Transmission may be by phase modulation and a terminal may include a processor 31 receiving information from return line 49 carrying PSK signals demodulated by 47 and passed through interface 50 to receiver 44, 45. Incoming serial digits are divided into characters of 28 bits and passed in parallel to address decoder and thence on receipt of periodic instruction from processor 31 through line 42 and highway 35. Receiver 44 includes a check register and invalid signal indications are stored in 45. Address decoder 34 also provides on line 36 a sync./no sync. signal on a succession of invalid indications. This activates a resync. device in 44 putting, into neutral state, the timing generator which is restarted at an appropriate point in its cycle by a sync. pattern recognition circuit which recognizes a determined series of fill bits inserted between messages. Transmitter 46 contains parallel/series converter and check bit generator also can provide indication on a line 41 that the underflow processor is supplying data insufficiently quickly;- alternatively an overflow indication on 42 prevents overwrite. The various parts of the arrangement are described in greater detail in connection with Figs. 2-16 (not shown). Each data link may operate asynchronously and clock extraction circuits incorporated into each receiver.
