In a facsimile transceiver, an independent, high frequency precision oscillator precisely times the generation of synchronizing pulses which are transmitted to a remote, similar transceiver. An identical precision oscillator assures that the receiver employs the transmitted synchronizing pulse to generate...http://www.google.fr/patents/US4290085?utm_source=gb-gplus-shareBrevet US4290085 - Synchronization system for variable line length facsimile transceivers
