Patent GB-1041193-A (GB)
Title: Improvements in or relating to receivers for suppressed-carrier single-sideband transmissions of binary-pulse signals
Inventor: OXFORD ALAN JOHN HENRY
IPC: H03D1/24
Filed: 1961-12-07
Abstract: 1,041,193. Automatic phase control systems. PLESSEY CO. Ltd. Dec. 5, 1962 [Dec. 7, 1961], No. 43886/61. Heading H3A. In a suppressed carrier S.S.B. system for transmitting binary pulse code signals using digit pulses of the opposite polarities, phase deviations of the receiver local oscillator from the suppressed carrier (which it reinserts) result in asymmetry of multiple pulses of the same polarity occurring in the demodulated pulse waveform. Fig. 2 shows, e.g., how peaks d, e, f occur at the beginning of such multiple pulses when the local oscillator is phase displaced in one sense. If the phase displacement is in the opposite sense the peaks occur towards the end of their respective multiple pulses. The position of such a peak between successive zero-crossings or at the two sides of a zero-crossing of the waveform is used to produce an error correcting signal for bringing the local oscillator into step with the suppressed carrier. In one embodiment, Fig. 1, the demodulated pulse waveform is made wholly positive by a full-wave rectifier 6 and, by pulses from a zero crossing detector 14, gated at 7 to a unidirectional peak amplitude store 8 during a period ¥T where T is the digit pulse duration. This peak value is continuously compared at 10 with a sample of the wholly positive waveform held by a short time constant store 9. The comparator output is sampled by a gate 11 just after the next zero-crossing, and immediately afterwards the peak store 8 is cleared (by zerocrossing detector pulses delayed at 18) preparatory to the next peak detection and storage. The sampled comparator output is thus in effect a comparison of the peak value of a multiple pulse with the value of such pulse during the last digit period of the pulse, and will vary in magnitude and sign according to the magnitude and sense of the local oscillator deviation. It is stored at 12 and over line 13 corrects the frequency and phase of the local oscillator. Since the comparator output is zero when pulses of opposite polarity follow one another, the output gate 11 from the comparator may be inhibited by pulses from a generator 20 such that the gate 11 is only opened when multiple-like polarity pulses are received. In a modification, Figs. 3, 4 (not shown), the demodulated output is applied through two paths, one of which is delayed by T (the digit pulse duration) to respective full-wave rectifiers with outputs of opposite sign, which are added, and the sum sampled by a gate circuit controlled by pulses from a zero-crossing-detector which are intermediately delayed by T/2. As a result the difference between the half-cycle (T/2) amplitudes before and after a zero crossing is taken and the series of pulses so derived is integrated in a bi-directional store whose output controls the phase of the local oscillator.

Title: Apparatus for transferring information
IPC: G11C11/44
Filed: 1960-12-29
Abstract: 902,068. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 29, 1960 [Dec. 30, 1959], No. 44561/60. Class 40 (1). A signalling system is characterized in that if a fault is detected in any transmission line one of a plurality of spare lines is automatically switched into circuit to replace the faulty line. A digital system is described in which each bit of data is transmitted by sending a current along one of a pair of lines representing 0 or 1. When current will not flow down a line, a fault is indicated and the particular line in which the fault is determined by the use of a Hamming error detecting code. In Fig. 1, four bits are transmitted from a register 10 by passing current along a selected line of each of four pairs of lines M1, M2, M3, M4. These four bits then have three checking bits K1, K2, K3 added by an encoder 12 and all seven bits, M and K, are transmitted via an isolating buffer 14, a check circuit 16 and a replacement switch to the transmission lines. If one of the transmission lines in circuit develops a fault, the buffer circuit will be unable to pass current down that line. This is detected by the check circuit which, by means of three pairs of lines 20, 22 24 indicates in which line the fault lies. This information is recoded and passed to a switch control circuit 40 together with information from a shift-register 46 indicating which of the spare lines is to be used next, and as a result the faulty line is disconnected from the check circuit and a spare line is substituted. Simultaneously, the fault will have been detected at the receiving station (Fig. 2, not shown) and a similar substitution will have been made. After each substitution, the shiftregister is advanced one step so that if a further fault develops the next spare line is used. Detailed circuits for the blocks shown in Fig. 1 are given. Conventional cryotron gating techniques are used as is illustrated by Fig. 4 which shows the register 10 and the encoder 12. The register 10 comprises four storage stages, each comprising set " 0," and set " 1 " input cryotrons, two cross-coupled cryotrons, and two output cryotrons. If a set " 1 " pulse is applied, the gate conductor of the set " 1 " input cryotron becomes resistive which switches the cross-coupled pair so that the upper gate conductor becomes super-conductive and the lower one resistive, and this results in current flowing in the " 1 " line of the M1 pair of output line. The M output lines also pass through a number of series connected control windings of cryotrons in the encoder which results in the production of three check bits K1, K2, K3 in the Hamming code.

Abstract: 1,065,003. Magnetic core data stores. ENGLISH ELECTRIC CO. Ltd. Nov. 26, 1963 [Nov. 28, 1962], No. 45083/62. Heading G4C. Anelectric storage comprises a threedimensional matrix of ferrite cores each linked by a programme' circuit' 14, an instruetion circuit 13 and'a sense circuit 15 whereby the programme and instruction circuits may be energized by pulse sources 21, 18 to read an instruction word through the sense circuit into a first register 23 and may subsequently be reenergized to write the instruction word back into the storage. The programme circuit includes two pairs 'of multi-position switches representing parameters necessary for the control of the screw-down position of rollers in a rolling mill. The switching means 19, 20 are actuated by electromagnetically operated reed-relay coils connected between pins arranged in pairs of a parallel row on an electricinsulating board. The board also carries two other pairs of rows of pins arranged 'on either side of the first rows and connected to selected fixed, contacts of four parameter-selecting rotating arm switches. The pins extend through the board and are connected to the coils on one side and between the inner and outer rows on the opposite side. The relevant programme is selected on the four rotating arm switches before operating the machine. On depression of a press-button switch by an operator, a switch 17a closes and a first readwrite current pulse is generated by sources 18, 21. This reads an instruction word into the first register 23 and also a second register 24 and subsequently writes the word back into storage from the first register 23 due to operation of switching devices 26 and the flow of inhibit currents through circuits 16. A second readwrite pulse reads the same instruction into the first register 23, a serial compdrator 27 checks that this is identical with that previous read into. the 2nd register and output signals appear at 25. The first register is then cleared and re-written in the store. After this first rolling pass the  operator again pushes the press-button. switch  to open switch 17a and close switch 17b. Each of the horizontal rows of cores 12 includes one coil indicating the parity of the instruction' word stored and this is compared with the parity of the second register 24 by a detector 29. A minimum setting detector 30 compares the output at 25 with a predetermined minimum  and gives a warning when the numerical value of a new instruction word in the second register 24 is below this value. A no-programme detector 48 gives warning. if the selector switches in .the programme circuit do not correspond with any predetermined rolling programme.
