Patent GB-1288970-A (GB)
IPC: H04N1/327
Filed: 1969-12-30
Abstract: 1288970 Facsimile system XEROX CORP 30 Dec 1969 [2 Jan 1969] 63261/69 Heading H4F A facsimile video signal which varies between two limits of voltage representing black and white, together with supervisory and other control signals are transmitted as a variable frequency by means of a voltage controlled oscillator 30, Fig. 1, in a predetermined order of priority. The signal with the first priority is the " force stop " signal which is coupled via control logic 40, and OR gate 60 to oscillator 30 for subsequent transmission by transducer 22, and is generated whenever the door to the facsimile unit is opened or the video scanner has reached the end of its travel &c. The transmitted stop tone lies outside the frequency range of the video information and when decoded by the receiving facsimile unit interrupts its operation. The " force white ", " force black " and the " video signal " are the second, third and fourth priority signals respectively. The force white and force black signals are used to synchronize the facsimile receiver with the transmitter and are transmitted at the beginning of each line scan, e.g. during the first 15 seconds the scanner applies to the logic 40 a black signal interrupted only by short pulses of white. A " send enable " signal applied to the transducer driver circuit 20 enables this circuit to apply signals to the transducer 22, i.e. this signal indicates that the facsimile unit is in the proper mode of operation. A " send ready " signal is coupled to a beep timer which transmits a signal within the video frequency range to the transducer driver to indicate to an operator or automatic circuitry at the receiver that the transmitter is in the proper mode of operation and is ready to begin transmitting the video information. Detailed circuitry is described with reference to Fig. 2 (not shown) the levels of the various voltages being set by a single potentiometer.

Filed: 1971-01-12
Abstract: 1297332 Automatic voltage control TAVIS CORP 12 Jan 1971 [16 Jan 1970] 1338/71 Heading G3R The amplitude of the output voltage of an oscillator 10 is stabilized by a control system comprising a member 18 which converts the A. C. output of the oscillator to a D. C. signal which is applied to one input 22 of a differential amplifier 20 to whose other input 24 is applied a constant reference voltage, the D.C. output of the amplifier 20 being applied to one input 12 of the oscillator to control the amplitude of its output voltage which is connected to the other input 14 of the oscillator to provide the positive feedback. In the described embodiment shown in Fig.2, the oscillator 10 comprises a pair of transistor amplifiers T1, T2 controlling a transformer 28 having windings 26, 30 respectively connected to D.C. supply terminals I, H, the winding 30 providing a sinusoidal output voltage at terminals G, D. The frequency of oscillation is determined by the tuned circuit formed by winding 30 and capacitor C1, and the positive feedback is effected by winding 26 which couples the output of winding 30 to the transistors T1, T2. A signal representative of the oscillator output is provided by tappings F, E on winding 30 and is applied to a combined differential amplifier and A. C. /D. C. converter comprising transistors T3, T4, resistor R3 and capacitor C2, the reference voltage 24 being provided by the circuit D3, R4. Members C2, R3, T3 detect and filter the A. C. signal applied to the base of transistor T3 to provide, at the emitters of transistors T3, T4, a D. C. voltage directly proportional to the peak value of the A. C. signal. To this end the discharge time of C2 through R3 is very long compared to the period of the oscillator output voltage. The D. C. output signal 25 from transistor T4 is applied via resistor R2 to the bases of transistors T1, T2, the arrangement being such that the D. C. drive current automatically adjusts to the load supplied by the oscillator in addition to providing the stabilizing function. Either or both of diodes D1, D2 may be omitted if either or both of transistors T3, T4 be replaced by high emitter-base voltage type transistors. If the load supplied by the oscillator has an inherent positive temperature coefficient (e.g. a variable reluctance transducer), diode D2 is omitted to give the oscillator circuit a balancing negative temperature coefficient. Stability against ambient temperature variations is provided by the mutually-compensating change of the base-emitter voltages of transistors T3, T4.
