Abstract
1,107,431. Electronic counters. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 7 July, 1965 [11 July, 1964], No. 28795/65. Heading G4A. The nines-complement of a predetermined count is set up manually at 20 and entered into counters 9, 10, 11 via stores 17, 18, 19. Initially output r of flip-flop 14 is energized so that input pulses pass limiter 12 and AND gate 13, the rear edge of each pulse stepping the counter 9. When the counters register 997 leads a-f, i are all marked so that the beginning of the next pulse, via lead k, operates AND gate 15. Flip-flop 14 changes over to disable 13 but opens AND gate 16 to the pulse corresponding to the predetermined count which restores the counters 9-11 to their starting points. An output is also taken from 16. Slower-acting counters 10, 11 may be used for the higher denominations, Fig. 4, with flip-flops 22, 21 reversing at counts of 900 and 90, respectively. The higher denomination may operate in pure binary code as shown by leads g, h.
