摘要： Heat generated by the projection lamp in a projecting apparatus is used to individually pop slides having improper curvature due to heat deformation. According to the invention, a slide positioned in the projection gate of the projector exhibits incorrect curvature, preferably as detected by the autofocus system of the projector, a door is opened allowing dry heat from the projection lamp to be applied directly to the slide, preferably until the slide reverts to a proper or normal curvature.

摘要： A slide projector for both front and rear projection includes a shallow lens tunnel for mounting a simple wide-angle lens. In a first aspect, a second lens port is added to a conventional slide projector designed for front projection. A mirror pivots to invert and direct light rays from an illuminated slide to the simple wide-angle lens. In a second aspect, only the shallow lens tunnel is present and a rotating slide gate orients the slide, depending on operation in front or rear projection mode. Front projection in the second aspect requires a lens tunnel extension.

摘要： The present invention provides for a processor or processing arrangement which includes a replenishment system that meters or dispenses an amount of replenishment solution in direct relation to an amount of photosensitive media that passes through the processor or processing arrangement. The replenishment system includes a dispensing chamber and a cam roller that is operationally associated with a conveying roller. The cam roller engages a valve on the dispensing chamber. When the valve is moved to an open position in relation to a rotation of the cam roller, an amount of processing solution is metered out of the chamber in an amount related to the amount of rotation of the conveying roller.

摘要： A film projector for use with frames of processed photographic film having frame-associated image orientation data. The film projector has a light source that emits a collimated beam and a film holder that is disposed to hold individual frames of film in the beam. The film holder is pivotable between a first and second orthogonal orientations. An optical projection system receives the beam from the film holder. The optical system propagates and focuses at least a portion of the beam on a viewing plane external to the projector. A sensor is disposed to read the frame-associated image orientation data. The sensor produces a signal responsive to the image configuration information. A controller receives the signal from the sensor. A repositioner is connected to the film holder. The repositioner is operatively connected to the controller to move the film holder between the orientations responsive to the controller.

摘要： A film cassette comprises a spool supported inside a shell for rotation to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is partly exposed, and a film exposure status indicator secured to the spool for rotation from an unexposed position for providing a visible indication that the filmstrip is unexposed to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. A spool lock is supported for movement to arrest the spool with the film exposure status indicator in the unexposed, partly exposed or fully exposed position, and to release the spool. According to the invention, the spool lock includes a film speed indicator for providing a detectable indication of the speed of the filmstrip which is not detectable when the spool lock is arresting the spool and is detectable when the spool lock has released the spool.

摘要： In a film cassette, a cassette shell has a pair of throat portions which together define a film passageway to the exterior of the shell, a spool is supported for rotation in an unwinding direction inside the shell, a convoluted film roll whose outermost convolution is a film leader is coiled about the spool, and a stripper is located immediately inwardly of the passageway to be received between a leading end of the film leader and a next-inward convolution of the film roll responsive to rotation of the spool in the unwinding direction to divert the leading end into the passageway to permit the leading end to be advanced from the shell. According to the invention, an inclined surface along one of the throat portions and an inclined surface along the other throat portion are arranged in offset co-planar relation, and a resiliently flexible shutter blade has two opposite ends one of which is secured to the inclined surface along one of the throat portions and the other of which rests freely against the inclined surface along the other throat portion to permit the leading end of the film leader to deflect the shutter blade out of its way when the leading end is advanced from the shell.

摘要： A film cassette comprises a spool supported within a cassette shell for rotation about an axis to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is only partly exposed, and a film exposure status indicator supported for rotation within the shell about the axis from an unexposed position to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. According to the invention, the spool and the status indicator are fixed coaxially to each other. The spool has three spaced detents arranged at separate locations for respective engagement to lock the indicator in its unexposed, partly exposed and fully exposed positions. The shell has an end cap including a locking pawl normally urged to individually engage any one of the detents, but which can be moved to disengage any one of the detents by a suitable device in a camera.

摘要： A film cartridge comprises a pair of film supply and film take-up housings and an intermediate bridge portion along which a filmstrip may be advanced from the film supply housing to the film take-up housing. The film supply and film take-up housings are separately connected at respective pivotal couplings to the bridge portion to permit the two housings to be individually folded against the bridge portion for storage purposes.
