Title: Device for automatic frequency control more particularly for the reception of carrier shift signals
IPC: H04L27/16
Filed: 1951-08-31
Abstract: 687,330. Automatic tuning control. STANDARD TELEPHONES & CABLES, Ltd. (Materiel Telephonique Soc. Anon.). Aug. 31, 1951, No. 20600/51. Class 38 (iv). In a receiver for frequency-shift telegraphy of the kind in which a local oscillator is automatically adjusted in frequency to compensate for frequency variations at the transmitter or receiver, means are provided to maintain correct adjustment during periods when no telegraph signals are being transmitted and either the marking or spacing frequency is emitted continuously. The receiver 1 supplies a potential to terminal 2 which is positive or negative relative to earth 3 according as the spacing frequency or the marking frequency is received. The terminal 2 is connected through oppositely-directed rectifiers 4, 5 to condenser-shunted resistors, the mid-points 9, 13 of which are connected through resistors 14, 15 to a terminal 16. If the local oscillator is correctly tuned, no voltage appears at the terminal 16, but if that oscillator is tuned too high or too low, the voltage at 16 trips one or other of the valves 18, 19 to operate relay 23 or 20 and so start up a motor 21, 24 in one or the other direction to operate a tuning- condenser 22 in the local oscillator circuit. With this known A.F.C. system, should signals cease and either the marking or spacing frequency be sent out continuously, the terminal 2 is continuously either positive or negative, and one or other of the rectifiers 4, 5 is inoperative, with the result that the local oscillator is automatically tuned to a frequency corresponding to the continuously-transmitted frequency, instead of the mid-frequency. To avoid this, the signal potentials at terminal 2 are supplied to a flip-flop valve pair 25, 26, the output of which is rectified at 28, 29 and integrated by the network 30, 31. So long as the voltage at 2 alternates in sign, a negative voltage is applied to the grid of tube 32 which is thereby blocked. When signals cease, the valve pair 25, 26 is inoperative, the tube 32 conducts and positive and negative voltages appear respectively at terminals 37, 39 connected by resistors 34, 35 to an earth point 38. One or other of the terminals 37, 39 is connected by a manual switch to a potentialdivider 44, from which a tapping is taken through a second selecting switch 40 to drive current through that pair of resistors 7, 8 or 11, 12 which is not receiving current from the terminal 2.

Abstract: 1,019,841. Transistor frequency dividing circuits; automatic frequency control systems. GENERAL TIME CORPORATION. May 24, 1963 [June 27, 1962], No. 20924/63. Headings H3A and H3T. A frequency divider comprises a relaxation oscillator in which a pair of transistors are symmetrically connected to windings of a saturable transformer, the frequency of oscillation being synchronized from a source of much higher frequency, e.g. up to x 1000. In one embodiment the bases and emitters of transistors 31, 32, Fig. 1, are back-coupled over windings 21, 23 and 22, 24 respectively of a transformer with a saturable core; resistors 35, 36 keep the base current within safe limits while resistors 37, 38 damp the transformer windings. Synchronizing is performed by injecting the synchronizing waves into an additional winding 50 on the transformer core. The power supply is derived from a source 45 via a voltage-stabilizing bridge network comprising resistors 41, 42, 43 and Zener diode 44. In another embodiment a phase-detector is used for synchronizing purposes. The detector comprises diodes 85, 86 (Fig. 3, not shown) to which sine wave or other synchronizing signals are applied in push-pull over transformer 80 and the output of the transistor oscillator in phase over transformer 90. The sign of the resultant D.C. produced across load resistors 93, 95 depends on the relative phase of the synchronizing signals and local oscillations, and this voltage is added algebraically to the supply voltage applied to the transistors from terminals 74, so controlling the triggering of the transistors and the frequency of oscillation.
