A control pulse generator for the cyclical fault-free generation of an accurate sequence of control pulses utilizing a quartz pulse generator which is operatively connected to and adapted to initiate actuation of a plurality of serially connected to delay members over a control circuit which is operative, at the termination of a cycle of actuation of the serially connected delay members, to limit the initiation of a succeeding cycle by a pulse from the generator to a predetermined period of time following termination of the first cycle of operation and functioning as a self-holding circuit when the period duration of the quartz generator signals coincide with the running time of the serially connected delay members. Further means are provided for checking the duration of the limiting period to insure proper operation.
A control pulse generator for the fault-free cyclical generation of an accurate sequence of control pulses, comprising a quartz pulse generator operatively connected to a control circuit having a first pulse-edge controlled D-flipflop, the pulse input of which is connected to the output of the quartz generator, a first monostable multivibrator, to a first dynamic input of which the pulse output of said first D-flipflop is connected, said first monostable vibrator having an output connected to the pulse input of a second pulse-edge controlled D-flipflop, one output of said second D-flipflop being connected to the input of a first delay member of a plurality of serially connected delay members, a directly acting blocking input of said second D-flipflop being connected with said quartz pulse generator, a second monostable multivibrator which has its dynamic input connected with the output of the last delay member of said serially connected delay members, an output of the second monostable multivibrator being connected to a directly acting blocking input of said first pulse-edge controlled D-flipflop and to the D-input of said second pulse-edge controlled D-flipflop.
