Abstract: A film developing system for a microimage recording apparatus of the type including an elongated film strip movable under tension along a film path. The film strip is of the type utilizing heat for developing latent image areas formed at an exposure station, and the improved developing station includes a support for holding the film strip between spaced apart support elements extending transversely across the film strip on opposite sides of a previously exposed latent image area. A developer shoe having an outwardly convex heated surface is adapted to contact a facing surface of the film strip between the supports for developing the latent image area. The developer shoe is mounted for movement between a first position spaced away from the film path and a second position wherein the film strip is tensioned to conform to the heated surface of the shoe for developing during a selected time period.

Abstract: A film developing system for microimage recording apparatus providing computer output on microfilm utilizing an elongated film strip movable along a film path and employing heat for developing latent image areas formed on the film at an exposure station includes a support for positioning said film strip along the film path at spaced apart locations on opposite sides of a previously exposed latent image area in position ready for developing. A tensioning system is provided for exerting tension on the film strip between said support locations and a developer shoe having an outwardly convex, heated, film contacting surface is adapted to contact the facing surface of the film strip between the supports for developing the latent image area thereon.

Abstract: A microimage recording apparatus of the type utilizing an elongated master film strip movable along a master film processing path and a duplicate film strip movable along a duplicate film strip processing path for making duplicates of successive developed image areas on the master film strip includes a duplication station having a support for the master film strip to position a developed image area thereon in a duplication position along the master film strip path. Support is provided for the duplicate film strip along a segment of the duplicate film processing path merging with the master film strip path at the duplication station. The master and duplicate film strips are biased together in close contact at the duplication station against a glass platen and light is passed through a developed image area on the master film strip to create a latent, duplicate image area on the duplicate film strip for subsequent development.

Abstract: A self-contained COM (Computer Output on Microfilm) microimage recorder provides completed microfiche records of computer generated images. A master film strip travels a path including exposure, developing and duplication stations. An optics assembly at the exposure station exposes a pattern of numerous images provided serially by a cathode ray tube onto an image area of the master film strip. The entire image area is developed by heat at the developing station. A duplicate film strip moves along a path merging with the master film path at the duplication station where an entire pattern of images is duplicated onto an image area of the duplicate film strip from a developed image area of the master film strip. Duplicate film image areas are cut from the end of the strip as individual microfiche records and exit from the recorder as completed records after being developed and cleared.

Abstract: A modular photographic film printer utilizes a direct current servo controlled main drive motor and belt drive to move a master film and raw film stock across printing heads without the use of intermediate sprockets. Film tension is controlled by tension control motors connected to the pay out and take up reels of the printer. The unit is modular in construction, and circuitry is provided for monitoring critical functions of the printer in order to locate malfunctions. Fiber optics are utilized in the sound track printing head to provide cool operation.

Abstract: A carrying and storage case for audio visual teaching aids fabricated from three interlocking sheets of corrugated cardboard or the like spaced and folded to resemble a house. One of the cardboard sheets forms the outside structure of the house, including the walls, roof and floor, the second sheet forms a chimney for the house, and the third sheet serves as a carrying handle, dividing wall and reinforcing structure for the carrying case.

Abstract: A printing head assembly for exposing raw stock film with a preprint film in a contact film printer including a dual roller gate assembly. The dual roller gate assembly includes a pair of rollers mounted on a roller frame for engaging the preprint film and raw stock film on opposite sides of the printing aperture for wrapping both the preprint and raw stock film about a segment of the printing sprocket of substantially greater length than the printing aperture. An adjustable biasing spring permits regulation of the tension applied through the rollers to the film runs. The dual roller gate assembly includes a selectively operable retraction device to withdraw the rollers away from the printing sprocket for loading and unloading the film printer. In an alternate embodiment, the dual roller gate assembly is pivotally mounted by an offset shaft which permits pivotal movement of the dual roller gate assembly to provide clearance for loading the film printer.

Abstract: Disclosed is a blower assembly for use in dispersing heat from an image projector with minimum air flow noise by interposing a constant torque clutch formed of a dual wound spring between the blower and a motor output drive to permit the rate of rotation of the blower to vary in response to variations in air weight due to changes in temperature, atmospheric pressure, and moisture content.
