KOPPLINGSANORDNING FOR CYKLISK ALSTRING AV EN SIGNALTEKNISKT TILLFORLITLIG FOLJD AV STYRPULSER

摘要

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.
