A Portable Synchronous Interlock Projection System
The studio-equipped electrical interlock projection system has certain disadvantages. It is expensive, cumbersome and stationary. A portable, lightweight interlock projection system, which employs mechanically locked-in sync of 16mm motion-picture film with the 16mm magnetic soundtrack, has been developed. The films are synchronized on a common sprocket-driven roller of a conventional optical, or optical/magnetic, projector. A series of rollers leads the magnetic film from its supply reel to the sprocket and then to its take-up reel. Constructed of simple, inexpensive components, it offers many advantages to the smaller commercial producer and the in-plant film department.
