Abstract: 1,088,193. Binary coded decimal counters. SQUARE D CO. June 23, 1965 [July 17, 1964], No. 26484/65. Heading G4A. A binary coded decimal reversible counter, comprises a plurality of stages 2‹, 2<SP>1</SP>, 2<SP>2</SP> and 2<SP>1</SP>, each stage having two bi-stable NOR gates, the states of which are determined by the input pulses and the states of the preceding stages. An addition pulse applied at the input U when, for example, the counter is in its 1110 state (representing the numeral 7) i.e. with NOR gates 12, 14, 16, 17 non-conducting to give a " 1 " output and NOR gates 11, 13, 15, 18 conducting to give a " 0 " output, charges capacitors 27, 87 so that on the termination of the pulse capacitor 27 discharges through diode 26 to switch NOR gate 11 to its non-conducting state and switch NOR gate 12 to its conducting state. Simultaneously capacitor 87 discharges through diode 64 to render NOR gate 18 conductive and gate 17 non-conductive so that the counter is in its 0111 state (representing the numeral 8). A subtraction pulse applied at the input U when the counter is in, for example, its 0110 state (i.e. 6) charges capacitors 56 and 38. On termination of the pulse the capacitors discharge through diodes 53 and 35, respectively, so that the first and second stages are switched and the counter registers 1010 (i.e. 5). Several such counters may be coupled to provide a multidecade counter
