Abstract: Apparatus for loading a radiographic film packet with an intensifying screen, and for discharging the exposed negative into automatic processing apparatus without the use of a darkroom.

Abstract: There is disclosed an assembly usable in a photographic apparatus for adjustably presetting the gap spacing of a pair of juxtaposed rollers used for spreading film processing fluid between a pair of sheets traveling therebetween. The presetting assembly includes a movable gap setting member having a plurality of surface portions formed thereon, each of which facilitates formation of a different gap which, in turn, facilitates a different processing fluid layer thickness. The member is movable in a manner which allows different ones of the surface portions to operatively cooperate with the rollers so as to establish correspondingly different gap spacings.

Abstract: An ophthalmic device comprising superposed pairs of light polarizing elements, one pair of such elements being fixed and the other pair being rotatable with respect to the fixed pair to provide a variable light transmission feature. The fixed pair of elements is retained by a frame member having an arcuate peripheral portion which engages a rotatable light polarizing element biasing means which is fixedly attached to each rotatable light polarizing element and prevents substantial axial movement of the rotatable light polarizing element.

Abstract: Apparatus for distributing processing fluid across a sheet of photographic material to facilitate the distribution of the fluid between that sheet and another sheet. The processing fluid is contained in one or more elongated flexible tubes, each provided at one end with a flow control nozzle and provided with flow control stops spaced by a predetermined length of the tubing to facilitate deposition of the fluid in a defined path across the sheet.

Abstract: An interlock mechanism is provided for use as an adjunct with a camera having a shutter and a lanyard operated film advancing and processing system which utilizes a film cassette contaning, in stacked relationship, a dark slide and a plurality of self-processable film units. Each film unit is adapted to be exposed and then processed in a consecutive sequence. The interlock mechanism functions to preserve the proper operating sequence and prevents the camera user from performing anomalous operations which could result in film losses due to the processing of non-exposed film units.

Abstract: A manually operated photographic processing system is provided for use with a film cassette containing, in stacked relationship, a dark slide and a plurality of self-processable film units that are adapted to be consecutively exposed and then processed by being advanced from the cassette after exposure, and then processed, as they are being transported through a pressure generating nip formed by a pair of juxtaposed rollers that are resiliently biased toward each other. The mechanism of the processing system is lanyard operated such that the pull force exerted by the user is utilized first to drive a film advance means that moves a film unit from the cassette into the nip between the rollers and is then transferred to drive at least one of the rollers which, in turn, provide a traction force to further transport the film unit through the rollers and process it as a function of its movement through the rollers.
