Abstract: 893,123. Transistor multi-stable circuits. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR-GENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Oct. 11, 1960 [Oct. 30, 1959], No. 34784/60. Class 40(6). [Also in Group XIX] A counter consists of n stages and associated networks containing elements having two conductive states and a gating circuit whereby a reset pulse is allowed to pass when the sequence of input pulses is interrupted. The stages, containing transistors X, Y, Z, form a chain counter operated through a single input A, only one transistor being in the conductive state at one time. A positive pulse from the newly conducting transistor, say X, is led to an associated network containing a condenser, say C4 causing a normally-conducting transistor P1 to be cut off for an interval greater than that normally occurring between two A pulses. Thus the next transistor P2 will normally be cut off by a positive pulse from Y before transistor P1 resumes its conducting state. If the sequence of pulses arriving at A is broken, however, the restoration of P1 causes a positive pulse at G14 which, together with the positive potential at G15 causes transistor Q to become non-conducting, and this, in turn, causes transistor R to conduct, and via rail 4, resets the chain counter. Specification 587,655 is referred to.
