A REMOTE CONTROL PROJECTOR FOR THE EXAMINATION OF EXPERIMENTAL RECORDS ON 35 mm. FILM

Abstract

A projector unit is described in which the film advance sprocket is driven by a reversible motor and the glass pressure plate is automatically released while the film is being moved. The film spools accommodate 100 ft. of 35 mm. film and take up slack in both directions. Several units may be used simultaneously for correlation of multiple records.
