Abstract: A manual override system for automatic photographic transparency processing and projection apparatus adapted to receive cassettes of film, each containing a film processor. The apparatus manipulates the film in the cassette to process it, unless it has already been processed, and projects processed film. A cassette is normally latched into the apparatus until the film has been projected and rewound. The override system comprises an emergency eject control for causing the apparatus to eject the cassette at any point in the operating cycle, and a replay control effective during the projection of film for partially rewinding the film and reprojecting selected portions of it.

Abstract: An automatic exposure control system for motion picture cameras in which a dual aperture iris driven by a nulling galvanometer in a bridge circuit with a photocell controls the aperture stop setting of the camera. The system is automatically correlated to the specific values of film speeds by sectors of graduated light filtering densities on an indexable filter disc positioned in front of the photocell and indexed by a lug on a cassette containing the film. The location of the lug or the cassette is correlated to the speed of film loaded therein. A different notch on the cassette is correlated to one of a plurality of mutually exclusive ranges of film speed and adjusts the operating range of the bridge circuit upon insertion of the cassette into the camera.

Abstract: A movie light, adapted for mounting on a motion picture camera, employing a crossed-lenticular lens for providing uniform illumination over a precisely controlled solid angle conforming to the maximum viewing angle of the camera, for providing efficient illumination of a scene during exposure operations and for providing a source of apparently low brightness to an observer located within the illuminated scene. The lighting unit includes a platform-like base which is adapted to receive an integrally combined high intensity source and dichroic reflector which directs a major portion of the visible radiation in a given direction for transmission through the lens element while laterally dispersing a major portion of the infrared radiation. An inclined mirror positioned over the source redirects the visible light from its given path to a lens system which consists of a Fresnel lens and a crossed-lenticulated screen. A lug member depending from the lower surface of the base is configured for attachment to the camera for orientation of the lighting unit such that its solid angle of illumination intercepts the viewing angle of the camera within the scene which is to be photographically recorded.

Abstract: A rear projection viewer, for projection of images of a film strip housed in a motion picture cassette, employing a single reflective mirror and an inclined viewing screen in a compact arrangement wherein the screen provides substantially the complete front face of the viewer. In its preferred embodiment, the viewer is configured for operation of a multipurpose cassette for processing of the film strip of such cassette and subsequent projection of the images recorded on such film strip, and the cassette includes a processing station adapted for optimumly dispensing processing fluid across the film strip when the cassette is maintained in an attitude such that the incremental sections of the film progressively advanced across the projection station opening are located in a predetermined plane. A cassettereceiving well, disposed in the top of the viewer housing, is adapted to receive the cassette and locate it below the top of the screen in an operative position with the progressively advanced, incremental sections of film disposed in the predetermined plane. Preferably, the screen is a lenticular structure which transmits projected images substantially uniformly over a given viewing zone, and additionally directs the viewing zone downwardly from an axis normal to the screen in at least partial compensation for the angle of inclination of the screen such that the viewing zone will include an audience area located along the longitudinal axis of the apparatus.
