Title: Delay-line phase-pulse generator
IPC: H04L27/20
Filed: 1959-11-27
Abstract: 882,144. Multiplex transmission systems. COLLINS RADIO CO. Nov. 27, 1959 [March 19, 1959], No. 40477/59. Class 40 (4). In an arrangement for changing the phase of an output wave in accordance with information to be transmitted, comprises an oscillator 10, frequency divided by a gate 11 opened by a -pulse in a circulating system comprising a delay line 26, and means for substituting in the circulating system a pulse derived from one of a number of tappings on the delay line, and selected by the information to be transmitted. The invention is applied to a system in which the phase change indicative of the signal is referred to the phase of the preceding element. As shown, bistable circuit 28 normally opens gate 27 and bistable circuit 44 normally closes gate 48. The output 8# of the oscillator 10 is gated at 11 to the input of delay line 26 whose delay is 1/# so that eight cycles later the gate is again opened. Thus, the filtered output applied to terminal 13 consists of an oscillation of frequency #. The information is applied to two channels 16, 17 to effect twinplex modulation, i.e. to effect four different phase shifts as determined by the combinations of space and mark on the two channels. The four taps of the delay line are fed to the OR gate 41 either through gates 32 . . . 34 opened in response to various combinations of signals on the two channels or in the case of the fourth tap, directly. Arrangements are provided that only the first pulse received by gate 41 is substituted in the circulating system. Thus at the beginning of a channel period the output from gate 11 is fed via gate 21 to trigger a monostable circuit 22 whose differentiated output changes over the states of bistable circuits 28, 44 to open gate 43 and close gate 27. The first pulse applied to gate 41 thus passes via gates 42, 14, 11 to the input to delay line 26, and also resets bistable circuit 44 to close gate 43 to any further pulses emitted from gate 41. Meanwhile, the original pulse emerging from delay line 26 finds gate 27 closed, but resets bistable circuit 28 so that the succeeding pulses may pass gate 51, as setting up a circulation at a new time position. The " mono-stable " circuit 22 is actually a slow free-running multivibrator so that it may provide an initial pulse for starting the system off. In a modification, Fig. 4 (not shown), a single bistable circuit is used to control both gates, the delay line having a length 15/8# the first portion 1# being used to provide the circulating pulse and the latter portion having the appropriate tappings. Specifications 828,782 and 871,331 are referred to.

Abstract: 1,059,362. Pulse and sawtooth circuits. TECHNISCH - PHYSIKALISCHE WERKST€TTEN VEB. Oct. 15, 1963, No. 40687/63. Headings H3P and H3T. A circuit for providing a linear sawtooth at K and a pulse at H comprises a capacitor 1 charged linearly by a valve 2 and discharged by a reciprocally-coupled pair of valves 3, 4. The anode load of valve 3 is shunted by cathode follower 10 so as to reduce the rise time of pulse H. The valves may be replaced by PNP transistors. In the arrangement described, when switch 24 is closed, the circuit is freerunning; capacitor 1 charging negatively via valve 2 during each sweep until the voltage at K rises sufficiently to turn on valve 3 which recharges capacitor 1 and turns off valve 4. When capacitor 1 has recharged, the conductive states of valves 3, 4 become reversed, the fall in anode voltage of valve 4 being differentiated at 12 and inverted by valve 11, turning on valve 10 and reducing the rise time of the brightening pulse at H. Switch 24 may be closed to adapt the circuit for control by negative pulses at T or positive pulses at the cathode of valve 11. Capacitor 19 and diodes 17, 17<SP>1</SP> prevent premature triggering before the flyback is completed. The operating point of valve 11 is stabilized by a degenerative cathode resistor 15 which is bypassed for negative pulses by a diode 16. Valve 11 may be replaced by a pulse transformer connected in the anode circuit of valve 4. The sweep may be linearized by the use of a Miller integrator comprising valve 2 or by the use of a triode or pentode with negative current feedback.
