Abstract
1,080,978. Electronic counters. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Sept. 29, 1965 [Sept. 29, 1964], No. 41328/65. Heading G4A. The operation of a counter is tested by comparing its cycle time with those of delay circuits. Marking terminal B enables clock pulses from TG to pass to a cascade counter comprising denominations K1-K3. At the end of each counter cycle when 000 is attained AND gate Ud1 sets flip-flop F to state I. When counting begins, time delay circuit Z1 begins charging its capacitor Cn, Fig. 2. Where T is the cycle time of the counter diode Dzn reaches firing- point after a time of about 0À7T, so restoring F to state II. In normal operation F alternates between I and II in each cycle. The commonest counter fault reduces cycle time to T/2 or less so that F remains in state I. Then after a time delay imposed by Z2, if B is still marked, an alarm A1 operates. Alternatively, if the counter does not reach 000 a further time delay circuit Z3 operates the alarm.
