Abstract: 1,036,720. Transistor gating circuits. E. K. COLE Ltd. Aug. 20, 1963 [Aug. 21, 1962], No. 31994/62. Heading H3T. [Also in Divisions G6 and H2] In a system of monitoring, e.g. for the instruments of atomic reactors to provide a warning and " shut down," the monitoring means comprises a first transistor TR1, switched on and off by a control signal, e.g. at A, B, C; means for applying a further signal D which, when the transistor is switched on, switches it off to produce an output signal; and an amplifier TR2, TR3 which responds to the output signal. As shown, in Fig. 1, transistor TR1i s switched on when two out of the three inputs A, B, C, supply signals indicating that the reactor instruments are functioning correctly, and in this condition input pulses at D produce output pulses at E. Should a fault occur, removing at least two of the inputs A, B, C transistor TR1 cuts off, no pulses are fed to output E, and a pulse is fed via capacitor C4 to operate an alarm circuit. A number of units may be connected in cascade, Fig. 3 (not shown), for monitoring a plurality of instruments and interlocks. When all the instrument and interlock contacts are closed a magnetic clutch is engaged and a control arm may be operated. If, however, one of the instrument contacts is opened, the clutch disengages and the arm is automatically lowered. Opening one of the interlock contacts also prevents operation of the arm.
