A New Convertible Projector for 35mm and 70mm Film

Willy Borberg, Bernard D. Plakun

A projector of basically new design is intended for the dual purpose of projecting either 35mm or 70mm film, at either 24 or 30 frames/sec. The different projection lenses are prefocused in precision fittings for ready interchange. Optical and magnetic soundheads are integral assemblies. Conversion from either film size to the other, and frame rate change, takes but a few minutes
