  • Patent number: 4143509
    Abstract: A time-keeping system of the type having an electromechanically driven, analog-type time display, has a purely electrical integral hour reset feature. The system comprises an analog time display including hour and minute hands driven through a mechanical transmission by a fast-response electromechanical motor. A stable oscillator generates a high frequency time base signal. A chain of frequency dividers coupled to the oscillator develops a time-keeping signal at a minute-related frequency for driving the analog time display in a normal time-keeping mode, and for developing hour reset pulses at a frequency much higher than one pulse per second for driving the analog time display during an integral hour reset operation.
