Abstract:
A solution delivery system for a processor holds and delivers the processing solutions at working temperature. The solutions are held in an airtight chamber in which they are heated to the correct temperature. The solution is then transferred to a holding chamber until released into the processor.
Abstract:
The method and apparatus supplies processing solution directly to the surface of a web of sensitized material by means of a movable applicator. The web and applicator are moved relative to each other to enable good mixing of the solution on the surface. The movable applicators can be moved in and out of contact with the material as required so that the process can be varied.
Abstract:
A processing drum is located within an enclosed chamber. The processing drum is rotated within the chamber, the chamber being provided with means to heat and circulate air throughout the interior thereof. At least one fin is provided around the outer periphery of the drum to aid heat conduction.
Abstract:
A method of processing a photographic material in which the material is loaded into a rotatable chamber and a metered amount of solution is introduced into the chamber. The chamber is rotated and the solution is continuously swept along the surface of the material, forming a wave through which the material passes to enable uniform processing.
Abstract:
A method of processing photosensitive material which passes through at least two processing solutions in which the material is rinsed after passing through a first solution and prior to passing through the second solution. The mixture of rinse solution and recovered first solution is returned to the process cycle to replenish the first solution.
Abstract:
Described herein is a clip arrangement for use in processing apparatus which have at least one continuous leader belt running therethrough for driving photographic material to be processed through the apparatus, the clip arrangement connecting the material to the leader belt. The clip arrangement comprises an adhesive element which secures the material to the belt.
Abstract:
Exemplary embodiments of the present invention include two half shells that can be operably joined together, in whose walls pouches are provided. Two elements, approximately formed as ladders, each include first transport rollers, the two ladderlike elements being configured for insertion in the joined together half-shells. The first transport rollers are disposed on the respective ladderlike elements in such a way that upon insertion of the ladderlike elements into the joined together half-shells, the transport rollers fit into the pouches of the walls of the respective half shells. Exemplary embodiments also include a central element which, after the insertion of the two ladderlike elements, can be placed between the two ladderlike elements to maintain the two ladderlike elements in position and which, together with the respective ladderlike elements and the respective walls of the half-shells, defines a conduit for photographic material to be developed. This conduit extends between each of the ladderlike elements and the central element, and between the walls of each of the half-shells and the central element. Second transport rollers are provided on the central element which, after the insertion of the central element, contact the first transport rollers of the ladderlike elements, so that the photographic material to be developed is guided between the first transport rollers and the second transport rollers and transported through the conduit.
Abstract:
Described herein is an arrangement which allows solution to be supplied to a process from a `bag-in-box` arrangement, used solution being returned to an emptied `bag-in-box` arrangement for disposal. The arrangement includes a process (40) having an inlet (46) and an outlet (48) which is connected to a valve arrangement (10) by way of the inlet (46) and outlet (48). Respective `bag-in-box` arrangements (62, 64) are connected to the valve arrangement (10) which determines whether the `bag-in-box` arrangement is connected to the inlet (46) or the outlet (48) by its position. The arrangement provides a system in which new `bag-in-box` arrangements containing fresh solution for the process (40) are connected to inlet (46) thereof regardless of their relative positioning. Using the valve arrangement (10), the number of connections and disconnections for the `bag-in-box` arrangements is halved.
Abstract:
A tapeless splicing system which allows the joining and separation of filmstrips without the use of tape. The system comprises forming an aperture (16, 26) in a leading end (12, 22) of a filmstrip (14, 20) and a tongue portion (28, 29, 30, 32, 34, 36) in a trailing end (24) thereof. The tongue portion (28, 29, 30, 32, 34, 36) of one filmstrip (20) is inserted through the aperture (16) of another filmstrip (12) by distortion as it is pushed through the aperture (16), the tongue portion (28, 29, 30, 32, 34, 36) and the aperture (16) being sized and shaped to provide effective interlocking between the two filmstrips (14, 20).
Abstract:
Described herein is a method and apparatus for processing photographic material in sheet form. The sheet (2) to be processed is formed into a generally tubular configuration and inserted between the nip of a pair of drive rollers (4, 6). Processing solution is applied to one or both surfaces of the sheet (2) via hopper arrangements (20, 22) formed in association with drive rollers (4, 6) and/or by applicator rollers (40, 42) having associated hoppers (44, 46) which are spaced from the drive rollers (4, 6). Squeegee rollers (30, 32) are also provided for removing excess processing solution.
