A film-treatment device has two spaced and generally parallel mounting plates each having a pair of plate holes and respective pairs of journals in the plate holes having respective journal holes centered on a pair of journal axes. The journal holes of the plates are coaxial with each other and the two journal axes are parallel. Rollers centered on respective roller axes each have a pair of substantially cylindrical end trunnions centered on the respective roller axis and rotatably received in a respective one of the journal holes for rotation of the respective roller therein with its roller axis coaxial with the respective journal axis. The journals of one of the journal axes are constructed so the respective roller can move against spring force limitedly away from the other roller. At least one journal of each journal axis is formed at the respective journal hole with two semicylindrical journal surfaces spaced axially apart, centered on the respective journal axis, of the same radius of curvature as the respective trunnion, and diametrally oppositely concave toward each other. Thus the respective trunnion rides on the respective journal surfaces with the respective roller axis lying on the respective rotation axis. This one journal of each journal axis is formed at the respective journal hole with two generally semicylindrical skew surfaces spaced axially apart, centered on respective skew axes inclined to and intersecting the respective rotation axes, of at least the radius of curvature of the respective trunnion, and diametrally oppositely concave toward each other.
摘要:
Apparatus for developing a photographic emulsion carrier. The carrier travels through a succession of tanks of photographic processing fluid. The apparatus includes mechanisms that forward the carrier through the tanks, a drive device that operates the forwarding mechanisms, guides that guide the carrier from one tank into the next, and means that connect an inlet for each processing fluid with its associated tank. The apparatus also includes at least one separate assembly associated with at least one tank, for forming a cascade which includes means for conveying the processing fluid from at least one cascade stage to the tank. The assembly, for forming the cascade is a separate module that rests as a cover on the tanks and has a separate inlet for receiving processing fluid. The cascade assembly accommodates a mechanism that forwards the carrier through it. This mechanism couples with the mechanisms that forward the carrier through the tanks while the cascade assembly is resting on them.

In a feedpipe of a container for refilling a photographic developing tank with a developer radial discharge holes are provided in the region of a valve mounted at the lower end of the feedpipe extended outwardly of the container. The developer liquid is discharged into the valve and then into the tank through these radial holes. To prevent overflowing of the liquid through these holes meshed elements are inserted into the radial holes.

An apparatus for reading out storage phosphor plates (2) for storing X-ray information with one or more rotating conveyance rolls (11 to 14) for conveying the storage phosphor plate (2), an alignment edge (19, 22) to which the storage phosphor plate (2) can be aligned, and a read-out device for reading out the X-ray information stored in the storage phosphor plate (2). For more reliable alignment of the storage phosphor plate (2), in particular also with a storage phosphor plate (2) orientated substantially horizontally, provision is made such that the storage phosphor plate (2) is conveyed by the rotating conveyance rolls (11, 12) in direction (R, R′) towards the alignment edge (19, 22) and a control device is provided for setting a pressure with which the conveyance rolls (11, 12) press onto the storage phosphor plate (2), the pressure being set such that a slack or slippage occurs between the rotating conveyance rolls (11, 12) and the storage phosphor plate (2) being conveyed when the storage phosphor plate (2) comes into contact with the alignment edge (19, 22), by means of which the storage phosphor plate (2) can change its orientation and thus be aligned to the alignment edge (19, 22).
摘要:
A sheet film processing apparatus for sheet film including a housing for holding a re-loadable film, and having an upper surface and a back surface, developing equipment including developing tanks with developing fluid, arranged above the upper surface, a housing cover for covering the developing equipment in a light impervious manner, elements for leading the film to the developing device, a fluid collector basin located between the developing tank and the upper surface for catching any developing fluid which may fall from the developing equipment, a waste water tank provided at the back surface, and a plurality of drain hoses connecting the tanks and the collector basin with the waste water tank so as to lead the developing fluid to the waste water tank. This leads to a particularly compact construction which is easily accessible for servicing.
摘要:
A developing device for a photographic layer carrier, particularly a film, includes two rotary transport roller pairs transporting a film in a horizontal direction over a bath containing a processing liquid. Two liquid-admitting chambers are positioned opposite to each other in spaced relationship to form a processing space through which the film is transported. Each chamber is subdivided into two portions by a comb-like partition which loosens vortexes generated in one chamber portion upon pumping the liquid thereinto and ensures a uniform distribution of the liquid discharged into the processing space through a slot provided in the second chamber portion.

A cassette (1) for a storage phosphor plate (2) comprises a cassette housing (4) with an opening (7) and a support (3) disposed movably within the cassette housing (4), wherein the storage phosphor plate (2) lies on the support (3). In order to simplify the structure of the cassette (1) and of the corresponding removal mechanism, provision is made such that the support (3) can be moved, together with the storage phosphor plate (2) lying on top of it, through the opening (7) of the cassette housing (4), at least partially from the inside of the cassette housing (4), and the storage phosphor plate (2) lying on the support (3) can be taken from the support (3) when the support (3) is located, with the storage phosphor plate (2) lying on top of it, at least partially outside of the cassette housing (4).
