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.

High-security identification card obtained by thermal dye transfer

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.

Film cartridge assembly with pressure plate

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.

Film cartridge assembly

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. The movement inhibiting means are disabled when the cover member is in its exposure window opening position.

Film retention in cartridge assembly

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.

Film unit assembly

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.

Battery package and assembly

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.

Electrochemical cell and battery

Apparatus is disclosed for pulling webs of random lengths from respective cartridges. Each web has an end portion which protrudes from its respective cartridge. The cartridges are advanced by an endless belt cartridge conveyor in a first direction while the web end portions are sandwiched between a pair of endless belt conveyors and advanced in a second direction at an acute angle with respect to the first direction. Due to such divergent advancement of the cartridges and the web end portions, the webs are pulled from the cartridges. A cutting wheel is provided to cut the web after being pulled from the cartridges.
