G. T. Lorance, F. B. Dibble, H. J. Reed

A 16-mm sound motion picture projection system according to U.S. Navy Bureau of Ships Specification CS-P-41A must meet high-quality standards for picture and sound reproduction, while retaining the necessary durability for Navy use. It must provide high light output with good light distribution, long film life, low flutter, low distortion, and good frequency response. A projector designed for this purpose uses a sprocket type intermittent and unit component construction for ease of maintenance. The paper describes the projector mechanisms and amplifier circuits, and states performance results.
