Abstract: A dye-receiving element and process for producing a high-security, monolithic identification card, the element comprising a support having thereon a dye image-receiving layer adapted to receive a thermally-transferred dye image, the dye image-receiving layer containing indicia printed thereon approximately 40-120 .mu.m in width.

Abstract: A photographic film cartridge assembly has front and rear opposed walls between which photographic film is movable to align image areas with an exposure window in the front wall. A film support surface is enterable into the cartridge assembly through the exposure window. An opening in the rear wall is aligned with the exposure window, and a pressure plate is retained on the rear wall for movement toward and away from the front wall. Baffle means on the pressure plate and the rear wall form a tortuous light path to prevent light entering the cartridge assembly through the opening from reaching the film.

Abstract: A photographic cartridge assembly includes (1) an opaque casing with an exposure window in its front wall and (2) a film unit rotatably mounted in the casing such that successive film portions can be aligned with the exposure window. An opaque cover member is mounted in the casing between the front wall and the film unit for oscillatory movement about an axis, both parallel to the axis of rotation of the film unit and between the exposure window and the axis of rotation of the film unit, into and out of alignment with the exposure window.

Abstract: A photographic film cartridge assembly includes (1) an opaque casing with an exposure window in one wall and (2) a film unit with photographic film. The film unit has an exposure region and is mounted in the casing for movement in a film advancing direction relative to the casing such that successive portions of the exposure region align with the exposure window. A cover member, including an opaque region, is mounted in the casing between the wall and the film for movement independent of the film unit. The cover member is movable between a closing position, in which said opaque region is aligned with and closes the exposure window, and an opening position, in which said opaque region is out of alignment with and opens the exposure window. Means, associated with the film unit and the cover member are provided for inhibiting movement of the film unit in the film advancing direction when the cover member is in its exposure window closing position.

Abstract: A photographic film unit, including a film disk carried on a hub, has a mass of firm material deposited between the disk and the hub so that the mass, rather than the dimensions of the respective parts, accurately determines the relative film-to-hub alignment. The hub initially fits loosely in a central film-disk aperture. The material, a thermo-plastic, is then melted ultrasonically to flow between the disk and the hub, eliminating the looseness, and maintaining the disk on the hub in accurate alignment. According to one disclosed embodiment, the thermoplastic material adheres a retainer ring to the hub with the film disk captured therebetween. The thermoplastic then fills the interstices between the ring, the hub, and the disk to exclude foreign matter, such as processing fluids.

Abstract: A photographic cartridge assembly includes a photosensitive film disk rotatably received between opposed parallel walls of a thin cartridge casing. The casing is adapted to be opened, to release the disk for processing and printing, by prying the casing apart until it fractures at one edge and then tearing the casing from the fracture toward the opposite edge. In order to insure that the resulting opening is at a predetermined location in the casing, and is large enough to remove the disk, channels are provided in a casing wall to lead the tear along two paths extending oppositely around the periphery of the disk from the one edge to the opposite edge.

Abstract: A film cartridge assembly is disclosed including a two-part casing with a film disk rotatably mounted therein. Individual image areas on the film disk are sequentially aligned with an exposure window in one casing part by rotation of the disk. An opaque cover member is mounted in the casing for reciprocating movement into and out of alignment with the exposure window to control admission of light to the film disk. Coupling means interconnect the film disk and the cover member to impart rotational movement to the film disk during and as a result of at least a portion of the movement of the cover member.

Abstract: An electrochemical cell, including a current-collecting rod of one polarity received within a cylindrical current-collecting sleeve of opposite polarity, is provided with a conductive flared end cap welded to one end of the rod and extending concentrically around one end of the sleeve a band of insulating material, such as plastic shrink wrap, extends between the cap and the sleeve to prevent shorting. When assembled in an appropriate housing with other such cells, the end caps engage adjacent sleeves to provide series electrical connections between the cells. Preferably, the flared ends of the caps include a sharp edge that gouges into the adjacent sleeve to reduce the contact resistance.

Abstract: Three cylindrical battery cells are physically disposed in a plastic housing with two of the cells spaced coaxially adjacent one another and the third cell spaced laterally adjacent the coaxial cells spanning the distance between the coaxial cells. An insulating band encircles the end of each cell, between the end cap and a current-collecting sleeve, to prevent shorting between the current collectors. The three cells are connected electrically by conductive elements, such as end caps or straps, that place the third cell in series between the coaxial cells.
