Abstract:
A method and apparatus for making a shaped-spring assembly. The method and apparatus utilizes a spring forming apparatus which facilitates the forming of shaped springs without adversely effecting the characteristics of the spring, and a magazine arrangement which stores and loads shaped springs, while maintaining the shape of the springs. The magazine arrangement further permits the storage of a plurality of the shaped springs without fatiguing a leading edge of the spring. With the apparatus and method of the present invention, it is possible to load empty shaped spring cavities at a select location, such as at a field site, and also have a steady supply of shaped springs available for quick replacement. The forming apparatus is designed so as to easily cooperate and/or be mounted onto the magazine arrangement so as to facilitate the transfer of shape springs which are shaped by the forming apparatus into the magazine arrangement.
Abstract:
A photographic processor and method of operation is disclosed. The processor includes a circular drum having first and second film processing paths, and a disk positioned inside the drum. The disk comprises a first set of disk teeth for engagement with perforations on a first type of film and a second set of disk teeth for engagement with perforations on a second type of film. The first and second set of disk teeth are positioned along a portion of an outer periphery of the disk. The processor also includes a circular dryer for drying the processed film. The dryer extends around an outer periphery of the drum.
Abstract:
A photographic processor having a circular processing drum is shown. The circular processing drum of the processor of the present invention includes a disk that is positioned inside the drum. In order to accommodate different types of film, the circular processing drum is adjustable to change the width and thereby, change a size of the film path within the circular processing drum.

Abstract:
A latched film unit has a support, a filmstrip held by the support, and a latch mounted to the support. The latch is reversibly switchable between a first state and a second state and can enable or disable an access right of a memory element in the film unit. A latching device operates the film unit.
Abstract:
A film cassette having perforated film for permitting automated extension of the film, the film cassette comprises a core having the film convolutedly wound on the core. A rotatable drum receives the core, and includes a recessed slot and a projection which engages a perforation of the film for permitting motion of the film as the drum is rotated. A shell receives the drum, and includes an opening and a finger that matingly engages the recessed slot of the drum for forcing the film through the opening of the shell and, consequently, out of the film cassette.
Abstract:
A method and apparatus for processing of filmstrip contained in a film cartridge. The apparatus having at least one processing tank for holding a processing solution, a holding mechanism for holding and retaining a film cartridge containing a filmstrip having a leading edge and trailing edge, the trailing edge being secured to the cartridge, a transport mechanism for moving the holding mechanism along the apparatus so that the holding mechanism can be located at a workstation located at one of said at least one processing tank, and a film drive mechanism for moving the film out of or back into the film cartridge while the end of the film is still attached to the cartridge.
Abstract:
A film cartridge is provided with an internal mechanism for engaging and pulling a leading end of film from a roll to extend the film through a cartridge exit port. A one-way clutch, including a rotational element captured in a ramped cage, moves in one direction to capture the film between the ball and cage and advance the film through the exit. Movement in the opposite direction releases the film and repositions the clutch for the next advance. Still more specifically, the cartridge includes a second and opposite working one-way clutch for preventing premature retraction of the film. A release mechanism is employed for disabling both clutches when desired for intentional rewinding.
Abstract:
A film cassette comprises a lighttight housing, a spool rotatably supported inside the housing, a filmstrip wound onto the spool, a film leader attached to a leading end of the filmstrip, and a sprocket coaxially connected to the spool with identical pitch teeth adapted to be received in respective perforations along an edge section of the leader wider than the filmstrip for advancing the leader (but not the filmstrip) from the housing when the sprocket and the spool are rotated in a film unwinding direction. Among the perforations that receive the teeth the perforation closest to the filmstrip is longer than the others to allow anyone of the teeth to readily enter that perforation when the leader is wound onto the spool after the filmstrip.
Abstract:
A film assemblage comprises an elongate filmstrip and a relatively shorter leader adhered together at respective overlapping areas and adapted to be wound onto a take-up spool in a camera beginning with the leader and followed by the filmstrip. The filmstrip and/or the leader has a hole located and dimensioned relative to the overlapping areas to receive at least one of the overlapping areas when the leader and the filmstrip are wound onto a take-up spool in a camera. Since one of the overlapping areas is located in the hole when the filmstrip and the leader are coiled tightly about the take-up spool, the double thickness of the overlapping areas will not leave any pressure marks on the filmstrip.
