Abstract:
The combination of a prism with integrally formed mounting ears and a mounting station into which the prism and its ears are placed. Once positioned, part of the mounting station is bent to secure the prism into its predetermined location. The mounting station retains the prism through its ears and not through any optical surface. Accordingly, all three optical surfaces of the prism are left unencumbered for more efficient cooling.
Abstract:
A motion picture film handling cassette and a motion picture projector or viewer with which the cassette is adapted to be used for processing and projecting a photographic film strip stored within the cassette. The cassette includes a processing station for treating the film strip with a liquid processing composition and a projection station for locating a light-reflecting element in operative relation with the film strip for projection. Provisions are made for introducing air into the cassette near the projection station such that the air flows over at least a portion of the light-reflecting element for simultaneously cooling the light-reflecting element and heating the incoming air to enhance drying of the processed film strip.
