A film magazine, which is adapted to receive a stack of self-processing film units, is provided with a shuttle that reciprocates between a pair of pressure rollers to release the respective film units one at a time for movement into an exposure position, to engage and thereby support the released film unit for exposure, and to cause the exposed film unit to be removed from the exposure position between the rollers to initiate its processing. The shuttle is recessed at its leading end, and is thi...

The film cryotron according to the invention comprises a superconducting ground plane with two superconducting electrodes arranged on said ground plane interconnected by an elongated distributed Josephson junction and provided with supply lines. The ground plane and electrodes are all insulated from one another. There are two holes in the ground plane opposite one of the electrodes, arranged so as to form a first screen at a portion in this electrode, shaped as a strip extending along the juncti...

An indicating arrangement for indicating the absence or presence of film in the interior of an X-ray film cassette includes an indicating member movably mounted on one portion of the cassette. Another portion of the cassette which is juxtaposed with the one portion has a recess therein, in which the inner end of the indicating element is received when film is absent from the internal space of the cassette, but which is covered by the film when the same is properly introduced into the internal sp...

A film-splicer for splicing together the abutting ends of a pair of films by means of a splicing label having supporting paper strips and a intermediate tear off piece. A base pivotally mounts a film-turning windowed flap. A pair of film clamps on the flap allow the locating of the film-ends-to-be-joined relative to the flap. An upwardly-facing projection extends upwardly from the base and through the window in the flap. Prongs extend upwardly from the projection for aligning the splicing label ...

A laminated film containing at least two layers of which one layer is a gas-barriering layer comprising a copolymer of vinylidene chloride with a reduced viscosity of 0.030 to 0.050 and the other layer is a strengthening layer arranged to be adjacent to the gas-barriering layer, comprising a copolymer of vinylidene chloride with a reduced viscosity of 0.050 to 0.075.

A photographic film assemblage including a film cassette having an exit through which a strip of film may be advanced, a spool rotatably mounted within the cassette, a strip of film coiled about the spool with a leading end thereof adapted to extend to the exterior of the cassette via the exit, and a strip of sheet material having an intermediate section, located between and in engagement with the outermost convolution of film and an interior wall of the cassette, and opposite ends which extend ...

An apparatus for processing exposed photosensitive film sheets. A liquid used to develop the images on an exposed element as it is transported through the apparatus flows from a trough located above the path of transport. The liquid passes through a screen as it is introduced to and as it flows from the trough.

A film safe for protecting photographic film from radiation, moisture and physical damage comprises body and cap portions, each formed of an outer layer of a material having high impact strength and a second layer formed of a radiation impervious material which is adapted to receive an inner layer of a non-metallic or plastic material shaped to surround a roll of photographic film. The body and cap portions engage to form a secure, fluid-tight seal and a continuous radiation impervious barrier a...

A used roll of photostatic film is guided through a series of bunny brushes and vacuum nozzles to reclaim the film. The brushes pick particles from the film. The vacuum nozzles, connected to a blower, remove the particles from the brush. The reclaimed film is then rewound on a core. The process of reclaiming this web of photostatic film carefully guides the web from the used roll through the brushes to the rewinding spool without creasing the web.

A heat-shrinkable multilayer film suitable for use in the packaging of a frozen poultry, includes a first outer layer comprising a blend of a propylene-ethylene copolymer having a high isotactic molecular structure with less than about 6% by weight ethylene and having a melt flow of from about 1.5 to about 18 decigrams per minute; a (butene-1)-ethylene copolymer having a high isotactic molecular structure with less than about 10% by weight being ethylene and having a melt flow of from about 0.1 ...
