1,048,698. Electronic counters. MANUFACTURE DES MONTRES UNIVERSAL, PERRET FRERES S.A., and FABRIQUES MOVADO. July 19, 1963 [July 21, 1962], No. 28768/63. Heading G4A. Carry or borrow in a multi-denominational counter is effected only when the appropriate AND gate is energized. Add and subtract pulses, respectively, are applied to gas tubes 3, 4, respectively, to generate anode pulses on guide electrodes 19 and 20 or 20 and 19, as the case may be, to step the count in a multi-cathode tube Z. A cathode pulse is also applied to the gas tube 36 or 37 of the next denomination but this pulse is ineffective unless accompanied by a bias from cathode K0 or K9 of tube Z, for forward or reverse count, respectively.
