Abstract

1382004 Automatic control LENINGRADSKY ORDENA LENINA POLITEKHNICHESKY INSTITUT IMENI M I KALININA and LENINGRADSKY ORDENA TRUDOVOGO KRASNOGO ZNAMENI ZAVOD ELECTRIK IMENI N M SHVERNIKA 22 Jan 1973 [27 April 1972] 3160/73 Heading G3N A programmer for successive timing of washing cycles, comprises an input unit 26 to which is connected a principal decimal counter of successively timed intervals, having a tens section 27 and a unit section 28, which are interconnected by a current-pulse distributer 29 via switching units 30, 31. A further decimal counter having a tens section 32 and a units section 32 is connected to the input unit 26 and a further control pulse distributer 34 via switching units 35, 36 for setting the number of repetitions of time intervals within several cycles. The principal and further distributers are similar in arrangement and comprise magnetic diode circuits. In the principal distributer 29, a group of magnetic diode circuits 37 are connected to transformers 39 and trigger output flip-flops 41 through a control circuit 40. For the control of a resistance welding operation, the timing of various working cycles is switched over as required by commutating devices 108 and signals for actuating servo units governing the force between electrodes are produced at outputs 109.
