Patent GB-1110093-A (GB)
Title: Electrical circuit units and oscillation generators including triggered pulse generators
Inventor: REES FREDERICK HENRY
IPC: H03K5/159
Filed: 1966-02-11
Abstract: 1,110,093. Pulse generators; logic circuits. STANDARD TELEPHONES & CABLES Ltd. 11 Feb., 1966, No. 6091/66. Heading H3T. A pulse generator is coupled to a delay line which has a delay equal to or greater than the duration of a pulse from the generator, an output being taken from a tap on the line to shut down the generator and thus determine the duration of the pulse obtained from the end of the line. The latter pulse may be fed back to trigger the pulse generator so that the arrangement is free-running. The arrangement of Fig. 2 is suitable as a clock pulse generator for a computer or an electronic telephone exchange. The pulse generator comprises a monostable circuit MS2 which is itself triggered by a further monostable circuit MS1 having a longer " on " state to protect MS2 from false triggering by spurious pulses. The pulse from MS2 is amplified and passed to a delay line DL, and when it reaches the tap it is returned to MS2 to revert the latter to its original state. MS2 could thus be a bi-stable circuit but the use of a monostable circuit assures that it will start again in the right state if the circuit should cease to operate. The output of the delay line is taken off through a buffer amplifier and majority logic circuit MC (see below) to re-trigger MS1. In a practical arrangement (Fig. 1, not shown) the circuit of Fig. 2 is quadruplicated for security, the outputs of the buffer amplifiers (except the last) being applied to the majority logic input circuits of the other three as well as its own input. Thus failure of one unit will not affect the output of the complete generator. The four buffer amplifier outputs may be distributed separately or applied in pairs to AND gates which feed two OR gates; monitoring the output of the latter provides a check on the system if one of these distribution systems is perioditally inhibited automatically or manually. The starting circuit of Fig. 2 is individual to each of the three " master " circuits, the three starting oscillators being coupled to majority logic circuits MCS of all three master circuits to trigger the monostable units MS1. By including a gate G fed from the input to MS1 all three master circuits are started together. Majority logic circuit (Fig. 3, not shown).- This comprises three diode AND circuits each supplied from a pair of master circuits, feeding a diode OR gate and a transistor buffer, to perform the logic function (AB + BC + CA). All the diodes and supply resistors are duplicated for security. Alternatively a fourth input could be taken from the fourth oscillator and the circuit would then perform the function (AB + CD).
