Abstract

1,125,711. Electronic counters. MASCHINENFABRIK AUGSBURG - NœRNBURG, A.G. 27 Sept., 1965 [26 Sept., 1964], No. 41077/65. Heading G4A. A reversible ring counter comprises in each stage a thyristor such as 310 which, when conducting, biases the adjacent thyristors 201, 401 through RC-diode circuits so as to respond to a negative impulse applied over a reverse or a forward counting lead, 11 or 12 respectively. As the adjacent thyristor becomes conducting so a pulse through capacitor 311 or 411 cuts off 301. The anode of each thyristor is connected to the corresponding cathode of a digitron (Fig. 2, not shown). Resetting is effected by momentary reversal of key 20. Two or more counters with radices having no common factor may be arranged, Fig. 3, to feed AND gates such as 50-61 so as to count up to the product of the counters.
