Abstract:
There is described a self-developing film unit which has a photosensitive member and an image-receiving member and wherein one outermost surface of the film unit comprises a support layer carrying a layer of a releasable material and a layer of an adhesive material. After an image is formed in the film unit by photoexposure of the photosensitive element and photographic processing of the exposed photosensitive element, the support and releasable material layer can be removed and the film unit or the image-receiving element, as the case may be, adhered to a surface for viewing of the image.
Abstract:
An elongated filmstrip is provided having two superposed sheets of photographic material helically wound in a cartridge. Typically, one of the sheets is a photosensitive image receiver and the other is a coated processing web. The lateral edges of the filmstrip are sealed to inhibit leakage of processing composition which is spread between the sheets during image development. The sheet which is on the outside of each roll convolution will have a longer path length than the inner sheet, and has sufficient elasticity to accommodate the path length difference. The elastic sheet is provided with a strippable, relatively non-elastic support before being transported through the coating machinery. The sheet, together with its coating and non-elastic support is then adhered to the other sheet of the filmstrip and the support then removed.

Abstract:
A photographic processing sleeve is provided for receiving and processing a dye donating instant film sheet to produce a photographic print. The sleeve comprises a film retaining sheet that is folded over along its lateral edges to form channels which slidably receive the film sheet, and edge strips, sometimes called side rails, which space the film sheet from the image-receiving sheet. After processing, at least a major portion of the image-receiving sheet, including the finished picture, is adapted to be peeled apart from the rest of the sleeve which can then be discarded.
Abstract:
A photographic processing sleeve is provided for receiving and processing a dye donating instant film sheet to produce borderless photographic prints. The sleeve is constructed of first and second sheets coupled together to form a pocket therebetween for receiving the film sheet. One of the sheets includes a central section which carries materials for immobilizing the dyes donated by the film sheet to form a visible picture in the central section. A stripping sheet forms an outermost surface of one face of the sleeve and releasably couples the central section of the first sheet to the remainder of the sleeve so the stripping sheet and the picture in the central section can be stripped away from the remainder of the sleeve.
Abstract:
Means are provided in a photographic film pack for urging the superposed sheet elements of a diffusion transfer film unit together during the withdrawal of said film unit from its container. Said means are useful for eliminating white specks in the resultant positive transfer print.
Abstract:
An auto-process film unit comprising a photosensitive sheet and a positive image sheet, which is bondable to the photosensitive sheet, but is initially separated therefrom by a removable light-proof, anti-adhesive strip, which forms a folded portion between the photosensitive and positive image sheets, and is attached at one end to a wind-up means. This film unit has the advantage that since the photosensitive sheet for production of a negative image and a positive image sheet onto which a corresponding image is transferred are not initially bonded together, processing solution may move freely therebetween, whereby even quality of a produced photograph is ensured.
Abstract:
An improved fluid receiving structure or trap for use with a self-processing photographic film unit or the like. The trap is best adapted for use in composite or integral film units in which it is permanently locatable entirely within the borders of the unit, making unnecessary its separation from the unit after processing. The trap comprises an inflatable bladder constrained by a substantially non-crushable framing structure.
Abstract:
An assemblage of ''''self-processing'''' photographic film units and leaders. The film units include photosensitive and processing elements arranged in separate stacks permitting sequential exposure of the photosensitive elements. The leaders serve to interconnect both the photosensitive and processing elements of each film unit and the respective film units. Only one leader extends from the assemblage at the time of each exposure and this one leader is adapted to be pulled from the assemblage to superpose the exposed photosensitive elements with its respective processing element, to transport that superposed unit from the assemblage and between a pair of pressure-applying members, and to advance a leader from the next successive unit to a position between the pressure members where it can be grapsed for superposing and transporting that next successive unit after its exposure.
Abstract:
FOR TRAPPING AND RETAINING THE EXCESS PROCESSING FLUID DISTRIBUTED BETWEEN AN EXPOSED PHTOTSENSITIVE SHEET AND A SECOND SHEET SUPERPOSED THEREWITH WHEN THE TWO ARE MOVED LONGITUDINALLY BETWEEN A PAIR OF PRESSURE APPLYING MEMBERS TO RUPTURE A POD CONTAINING AN AMOUNT OF PROCESSING SOLUTION IN EXCESS OF THAT REQUIRED TO PROCESS THE EXPOSED LATENT IMAGE, THE TRAILING END OF ONE OF THE SHEETS IS EXTENTED BEYOND THE IMAGE AREA THEREOF AND IS MEDIALLY FOLDED BACK UPON ITSELF TO PROVIDE A FLAP THE FREE END OF WHICH WILL EXTEND BACK AT LEAST TO THE TRAILING END OF THE OTHER SHEET, AND PROBABLY BEYOND AND UNDER THE TRAILING END OF THE OTHER SHEET, TO FORM A TRAP FOR THE EXCESS PROCESSING FLUID. THE SHEET WHOSE TRAILING END IS FOLDED BACK TO FORM THE TRAP SHOULD BE MADE OF MATERIAL HAVING SUFFICIENT RIGIDITY AND/OR RESILIENCE THAT IT RESISTS FOLDING SO THAT THE FREE END OF THE FOLDED-BACK FLAP NORMALLY REMAINS SPACED FROM THE SHEET PROPER TO FROM AN OPEN MOUTH FOR RECEIVING EXCESS PROCESSING FLUID. THE LONGITUDINAL EDGES OF THE FOLDED-BACK TRAP ARE SEALED TOGETHER IN SUCH A WAY AS TO PREVENT THE FLOW OF PROCESSING FLUID FROM THE EDGES BUT TO ALLOW THE ESCAPE OF AIR THEREFROM. AT LEAST ONE PROTUBERANCE IS EMBOSSED IN EACH OF THE SEALED EDGES TO EFFECT A SIGNIFICANT SEPARATION OF THE PRESSURE APPLYING MEMBERS AS THE TRAP PASSES THEREBETWEEN WHEREBY THE FOLDED-BACKED FLAP WILL NOT BE COMPRESSED SUFFICIENTLY TO CAUSE A BACK FLOW OF ANY FLUID WHICH HAS ENTERED THE TRAP.
