Abstract
993,022. Clock systems. ELEKTROCAS NARODNI PODNIK. Dec. 20,1961 [Dec. 21,1960; Feb. 16,1961], No. 45709/61. Drawings to Specification. Heading G3T. A system of master and subsidiary clocks is periodically corrected by a wireless time signal composed of a combination of impulses. The correction means is associated with signal analysing means which responds to a time correction signal and detector means determines the character and extent of the master clock deviation so that the master clock temporarily drives the subsidiary clocks slower or faster until they are corrected. In one example the master clock is driven by a synchronous motor and correction is effected by changing the rate of impulses from the master clock to the subsidiary clocks, the master clock itself being corrected by a heart shaped cam mechanism. The signal analyser includes a pawl and ratchet mechanism driven by the impulses. In another example an auxiliary synchronous motor regulates the speed of the main synchronous motor driving the master clock and a generator picks up the speed of the main synchronous motor and drives the synchronous motors of the subsidiary clocks.
