ABSTRACT:
A phase regulating circuit in which a phase comparator is supplied with output pulses of a pulse generator over a frequency divider and, for comparison therewith, the timing pulses derived from a displacement pick-up, with the output of the phase comparator being utilized for controlling the pulse generator to regulate the phase of the output thereof, means being provided for interrupting the supply of timing pulse from the frequency divider to the phase comparator in the event of an interruption in the displacement pick-up pulses, and which, upon recurrence of the displacement pick-up pulses, reconnects the frequency divider to the comparator for supplying divider output pulses to the comparator which have been matched in phase as close as possible to that of the displacement pick-up pulses.
