Abstract: 680,726.. Valve circuits. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Jan. 1, 1951 [Jan. 17, 1950], No. 1235/50. Class 40 (vi). [Also in Group XL (b)] A six-point cyclic counter comprises three double-triodes V7, V8, V9 connected in a symmetrical ring circuit with the two halves of each triode reciprocally coupled and the anodes of succeeding values directly coupled. The circuit is triggered by positive pulses developed across a common cathode load R36 from a driver stage V6B, and at any instant three adjacent triodes in the ring will be conducting and the remaining three cut off. Assuming V7A, V8A and V9A are conducting, the anodes of V7A and V8A will be low in potential and consequently the grid potential of V7B will also be low by virtue of the direct connection via R51 to the junction of resistances R46, R55 joining the anodes. The grid of V8B is likewise held at a low potential and V7B and V8B are both cut off. In the case of V9B the grid potential is determined by V9A and V7B, the first of which is conducting and the second cut off. Resistor R80, however, is much smaller than resistor R38 and the grid potential applied to V9B, although less than that applied to V7B and V8B, is sufficient to cut off the valve. Fig. 5 shows the grid potentials existing throughout the circuit. When a cathode pulse of the amplitude shown is applied to the circuit it is only sufficient to cut off V9A. This results in a position pulse being delivered via C23 to the grid of V9B causing the valve to conduct. Valves V7A, V8A, V9B are now conducting and valves V7B, V8B and V9A are cut off, and as the circuit is symmetrical, a new stable state is attained which lasts until the next cathode pulse. Fig. 4 shows the potentials of the counter anodes on successive cathode pulses. The circuit may be modified so as to be triggered by negative grid pulses.
