Mechanical Advantages of the Optical Intermittent Projector

J. L. Spence

The mechanical problems of optical intermittent projectors, related to threading of film, gate structure, running time per reel, operating characteristics, and difficulties more intimately connected with sound film itself, are briefly described. In addition, some attention is given to the economic problems involved in film damage and wear, in the wearing of machine parts, in the use of duplex film on thinner film base. The paper refers to these problems specifically in relation to 16 mm. machines.
