Abstract: The invention relates to a projection system for image representation, with a display (61), at least one lamp (10), and at least one sensor (7) for generating a sensor signal for monitoring and compensating changes in the luminous flux provided by the at least one lamp (10). To achieve a monitoring of the light quantity actually incident on the display (61) which is as accurate and as interference-free as possible, an optical component (31) is arranged in a light path between the lamp (10) and the display (61), which component allows a first light component to pass through and reflects a second light component such that one of the light components is directed at the display (61) and the other light component is directed at the sensor (7) arranged outside the light path. A sensor signal generated in this manner renders it possible to compensate for fluctuations in the luminous flux provided by the lamp (10) through the control of a lamp driver (101) in an effective manner and practically without light losses and without being influenced by the brightness fluctuations generated by a color modulator or other components of the system.

Abstract: A slide magazine has a base portion and partitioning walls which project upwardly away from the base portion at mutual spacings to form compartments for accommodating respective slide frames. The partitioning walls are of a height which is adapted to the slide frames and at their ends remote from the base portion are connected together by a strip-shaped holding portion extending over the length of the slide magazine so each compartment can be loaded and unloaded from both sides. To prevent the slide frame in a compartment from falling out laterally, provided at each side of each compartment is at least one resilient retaining portion in the form of a resilient finger with a retaining nose arranged to engage the slide frame.

Abstract: A system for facilitating the handling of overhead projector transparencies on an overhead projector of the type including an upwardly facing projector platen. The system includes a frame assembly to provide a support surface adjacent the projector platen. A transparency storage cassette is supported on the support surface in alignment with the projector platen and generally includes a housing defining a closed chamber. An upwardly biased follower plate is mounted within the chamber to support a stack of transparencies. A door allows loading of the transparencies into the chamber. Between the door and the follower plate is a cam arrangement to move the follower plate downwardly against the bias when the door is moved to an open position to thereby facilitate the loading of the transparencies into the chamber. A transparency discharge slot is provided in the housing along the side adjacent the projector platen and opening in the top wall of the housing permits manual access to the top transparency in the stack to thus allow the top transparency to be slid from the stack out of the housing through the discharge slot to a projecting position on the projector platen.

Abstract: A slide projector having a projector frame and a light source and lens assembly mounted on the frame which includes a cassette having a plurality of slide frame receptacles for receiving slide frames therein. The cassette is movable so as to bring selected slide frames into a dispensing position. A frame grabber mounted on the projector frame is movable in a direction perpendicular to the lens axis from a projection position in which an image of an engaged slide can be projected to a dispensing position in which slide frames can be sequentially brought into alignment with the grabber. Once engaged by the grabber, a selected aligned slide frame can be extracted from the cassette and moved to the projection position.

Abstract: The present invention provides a process for feeding transparency sheets having a soft coating thereon from a tray of such sheets. The transparency sheets are interleaved with plain paper separator sheets in a tray so that at the front end of the tray, the ends of the plain paper separator sheets extend beyond the ends of the transparency sheets. A sheet feed means positioned adjacent the front end of the tray engages the extended end of the first of the plain paper separator sheets in the tray. At start up, the sheet feed means does not engage the transparency sheets. The sheet feed means moves the engaged plain paper separator sheet from the tray wherein the movement of the engaged plain paper separator sheet moves the adjacent transparency sheet from the tray.

Abstract: A slide tray position sensing arrangement is provided for slide projector apparatus. The slide tray position sensing arrangement is arranged at a detection station. A coded aperture ring is provided that moves in a manner correlated to the movement of a slide tray turntable. The slide tray turntable carries the slide tray that holds the slides for projection and also functions as a tray transport arrangement. The coded aperture ring includes two circumferential arrays of apertures. Each of the apertures in the first array corresponds to a controlled slide position of a first tray type; e.g., an 80 slide tray. Each of the apertures in the second array corresponds to a controlled side position of a second tray type; e.g., a 140 slide tray. The slide tray position sensing arrangement is controllable to selectively sense the appropriate array of apertures corresponding to the slide tray type being utilized. In a first arrangement, the position sensing arrangement is selectively movable between two detection positions; each of the detection positions being aligned with a respective one of the aperture arrays. In a second arrangement, two detection arrangements are provided; each of the detection arrangements being aligned with a respective one of the aperture arrays.

Abstract: A slide viewer or projector is provided with a device for preventing two or more slides from attempting to enter into the viewing or projecting area simultaneously. The device comprises a barrier with a wiper pivotally mounted thereon. The barrier and wiper are spaced apart from the path taken by a slide so that the slide pivots the wiper against the action of biasing means and then the barrier is raised into engagement with the upper surface of the slide and this allows the wiper to wipe over the upper surface of the slide to "kick off" any other slide resting on the surface.
