A System for Universal Synchronization

A system (called The Rotosyn System) was designed to synchronize film transport mechanisms. It has found its way into the studios of Europe and other countries. It permits the synchronous drive of film transport mechanisms which are fitted with a standard synchronous motor. The principle of the system is that three-phase a-c power is supplied with a frequency rising from 0 to 50 cycles, and a voltage which is in accordance with the increasing impedance. The power is supplied by a Rotosyn converter which is relay-controlled in starting and stopping. The advantage of this system is that the film transport mechanisms may be operated either from power line or from Rotosyn supply and need not be fitted with special motors.
