Abstract
1,113,321. Electronic counters. SPERRY RAND Ltd. 3 Sept., 1965 [4 Sept., 1964] No. 36269/64. Heading G4A. In a binary-coded decimal counter carry is effected when stage 2 turns on at the tenth pulse by the resulting pulse acting on differentiating network C A , R B' D B to turn stage 8 off, the resultant carry pulse at 23 from stage 8 acting then over D E to restore stage 2. In reverse counting the first pulse changes the count to 1111, the output from stage 8 over D c and D E immediately changing the count to 1001. In a modification (Fig. 4, not shown) the tenth pulse causes stages 2 and 8 to turn stage 4 on, giving 0111. Stage 4 immediately changes stage 2 to 0 over a differentiating network, the resulting stage carry rippling through to changes 4 and 8 to 0. Transistor differentiating networks may be used.
