Description:Excerpt from Journal of the Society of Motion Picture and Television Engineers, Vol. 1 of 2 The projector used for this equipment drives a 35 mm motion picture film at the standard (nonintermittent) speed of 24 frame/sec and produces a television signal of 525 lines and 30 frames interlaced 2 to 1. The projector utilizes a system of movable plane mirrors mounted on a rotating drum and controlled by a single stationary cam. Vertical jitter in the television image is minimized by means of an electronic servo system operating on the film sprocket holes, resulting in a residual vertical motion of about 1/2000 of a picture height. A second electronic servo system is incorporated to suppress flicker. The combination of this scanner and a high-grade monitor is capable of producing a television picture with a resolution corresponding to about 8 me and with good tone rendition over a range up to 200 to 1. The Problem of designing a motion picture projector, in which the film motion is continuous, has occupied inventors and designers almost since motion pictures first made their appearance. In the early days of motion pictures the need for a continuous projector stemmed largely from a desire to decrease the wear and tear suffered by the film in the intermittent projector. Later on, with the advent of sound pictures, it was felt that a continuous projector could fit in better with a machine in which the film had to move continuously through the soundhead. Many different types have been proposed and patented but very few of them have gone beyond the experimental stage. A measure of the interest in this problem may be obtained from the bibliography at the end of this paper in which are listed the more important papers published on the subject during the years 1920 - 1945. One particular type of continuous projector, the Mechau projector, did reach the commercial stage and was used in a limited number of German motion picture theaters in the 1930's.
