H. Griffin

A résumée of the existing situation with respect to sprockets for 35-mm. sound and projection equipment is first presented, followed by a discussion of the interference between the film and the sprockets that transport the film, for sprockets of various dimensions. As a result of the study, sets of dimensions are proposed for the feed- and hold-back sprockets and for the sound sprocket, submitted for the consideration of the Standards Committee of the Society.
