Abstract

Abstract A photographic material processing module usable alone for all the processing steps in a processing procedure, or with like modules in side-by-side relation, each module performing one or more of the processing steps. Exposed photographic material is mounted in a cylindrical container having at one end a cover provided with an opening for receiving and discharging processing liquids. The module has a mechanical arrangement for rotating the container a few revolutions in one direction followed by a few revolutions in the opposite direction, and, in preferred form, a mechanism for simultaneously reciprocating the container axially, such movements providing optimum shear relation between processing liquid and photographic material for streak-free processing. A liquid supplying system is provided for feeding measured amounts of processing liquid at proper temperature into the container, and for elevating one end of the container to discharge the processing liquid at the conclusion of a timed processing step. Finally, the module has a transport device for moving the container from the module to an adjacent module at the conclusion of the processing step or steps performed in that module.

Claim 3
Dependent Claim 38 words
The module of claim 1 with the addition of means including a switch arm on said support for initiating a cycle of module operation when said switch arm is engaged by a container being moved into the module.
Claim 4
Dependent Claim 273 words
A photographic material processing module usable alone or with like modules arranged in adjacent side-by-side relation, comprising: a support having front and rear portions; a cylindrical container having a cylindrical wall for holding photographic material on the inside thereof in closely spaced relation with the cylindrical wall, said container including a front cover and a rear cover having an opening for receiving and discharging processing liquids; a pair of laterally spaced shafts mounted for rotation on said support and extending from front to rear, said container being positioned horizontally on said shafts; means for rotating said shafts to rotate said container a few revolutions in one direction followed by a few revolutions in the opposite direction during operation of the module; means on said support for feeding processing liquid into said cylindrical container through said rear cover opening; and means on said support for elevating the front end of said cylindrical container to discharge processing liquid through said opening, said means for elevating including an electric motor, a cam driven through one revolution by said motor, a first lever pivoted on said support and actuated by said cam, a transverse shaft mounted for rotation on said support below said container, a longitudinal arm extending from said transverse shaft below said container, a container engaging cradle at the free end of said arm below the front portion of said container, and links and levers connecting said first lever and said transverse shaft, whereby said cam is effective to elevate said cradle and thus the front portion of said container, hold same elevated for discharge of the processing liquid and return same to starting position.
Claim 5
Dependent Claim 273 words
A photographic material processing module usable alone or with like modules arranged in adjacent side-by-side relation, comprising: a support having front and rear portions; a cylindrical container having a cylindrical wall for holding photographic material on the inside thereof in closely spaced relation with the cylindrical wall, said container including a front cover and a rear cover having an opening for receiving and discharging processing liquids; a pair of laterally spaced shafts mounted for rotation on said support and extending from front to rear, said container being positioned horizontally on said shafts; means for rotating said shafts to rotate said container a few revolutions in one direction followed by a few revolutions in the opposite direction during operation of the module; means on said support for feeding processing liquid into said cylindrical container through said rear cover opening; and means on said support for elevating the front end of said cylindrical container to discharge processing liquid through said opening, said means for elevating including an electric motor, a cam driven through one revolution by said motor, a first lever pivoted on said support and actuated by said cam, a transverse shaft mounted for rotation on said support below said container, a longitudinal arm extending from said transverse shaft below said container, a container engaging cradle at the free end of said arm below the front portion of said container, and links and levers connecting said first lever and said transverse shaft, whereby said cam is effective to elevate said cradle and thus the front portion of said container, hold same elevated for discharge of the processing liquid and return same to starting position.
