Abstract
NEWCOMERS in the technical branch of the motion picture industry are usually unfavorably impressed with the intermittent movement of the projectors in universal use. It has been said that nature abhors a vacuum, and it may similarly be said that the mind of the mechanical engineer abhors an intermittent movement. In the projection machine of today, the visiting engineer finds a mechanism of steel feeding a fragile ribbon of celluloid by imparting rapid jerks applied through unyielding sprockets meshing with perforations in the celluloid. It requires no great perspicacity to see that an arrangement of this kind must lead to trouble of various kinds, and most of you will agree with the writer when he says that the intermittent movement constitutes a great hindrance to the simplification of projection apparatus. With the introduction of talking picture apparatus a move in the direction of simplicity will undoubtedly be made and it is the thought of this writer that it is the duty of the Society to study and to encourage development in the field of optical intermittent projectors with the idea of eliminating as much of the existing troubles as possible.
