摘要： A machine to facilitate editing of several films employs sprocket wheels spaced vertically along a central vertical shaft. The sprocket wheels are individually selectively engageable and disengageable from the vertical shaft to permit the synchronization of the films to be adjusted and maintained. In a first embodiment, the supply reels and the take-up reels associated with each sprocket wheel are supported at the same height as the sprocket wheel at the left and right sides of the machine, respectively, in stacked arrangements. In a second embodiment, the supply reels and the take-up reels are supported in terraced arrangements. In both of these embodiments, a central area of the top of the machine between the supply reels and the take-up reels is left clear as a working space, giving the operator easy access to the reels and to the sprocket wheels. Each film passes through only a single sprocket wheel, and therefore is quickly threaded and unthreaded by the operator.

摘要： A motion picture film projector includes a sound head for playing back or for recording a sound track on the film. Absolute synchronism between the picture and sound is assured by the use of a single motor and common shaft to move the film past the sound head and to rotate the optical rectification system. In one embodiment, the sound head is mounted on the concave side of a stationary arcuate film guide opposite the sound track, and the film is driven past the sound head by a sprocket wheel mounted on the common shaft adjacent the optical rectification system.

摘要： When used for projecting or editing motion picture film the optical rectification apparatus produces a stationary image of a frame of a moving film and a succession of superimposed stationary images from successive frames of the moving film. The apparatus employs an optically transmissive hollow cylindrical prism having a cylindrical external surface and an internal surface consisting of a number of facets. Light from the moving film is passed outwardly through the wall of the rotating prism and through a stationary plano-concave cylindrical lens positioned with its concave surface adjacent the external surface of the prism, but spaced slightly from it. The prism is connected to the same shaft as the film sprocket wheel resulting in an isotransport system in which the prism rotates in synchronism with movement of the film to deviate the light through an angle sufficient at each instant to compensate for the angular deviation of the light caused by movement of the film.
摘要翻译：当用于投影或编辑电影胶片时，光学整流装置从移动胶片的连续帧产生移动胶片的帧的静止图像和连续的叠加的静止图像。该装置采用具有圆柱形外表面和由许多小面组成的内表面的透光中空圆柱形棱镜。来自移动薄膜的光从外部通过旋转棱镜的壁并通过固定的平凹圆柱透镜，其位于其凹表面邻近棱镜的外表面，但与其稍微间隔开。棱镜连接到与薄膜链轮相同的轴上，从而产生等离子体输送系统，其中棱镜与薄膜的运动同步旋转，以使光在每一时刻足够的角度偏转以补偿光的角度偏差由电影的运动造成的。
