  • Processing photographic material
    Patent number: 6161968
    Abstract: Photographic processing apparatus comprises a combination of a surface processing stage and a replenishable tank processing stage. This allows advantage to be taken of the low quantities of processing solution that are characteristic of surface processing and the total immersion that is characteristic of tank processing.
    Type: Grant
    Filed: October 6, 1998
    Date of Patent: December 19, 2000
    Assignee: Eastman Kodak Company
    Inventors: Anthony Earle, Jeffrey K. Green, Zoe Orr, Leslie R. Wells
  • Processing photographic material
    Patent number: 6152617
    Abstract: Photographic material is processed in a sequence of stages by the application of solution to an upper surface thereof as the material is carried on endless belts beneath respective coated roller arrangements. Each roller arrangement is movably mounted in a slot so that the point along the stage at which the solution is applied to the photographic material can be varied, thereby to vary the time for which the material is subject to the processing treatment.

  • Method of processing a silver halide photographic element
    Patent number: 6037110
    Abstract: A method for processing a silver halide photographic material comprises the steps of developing, fixing and washing the photographic material. The fixing step is carried out using a fixing solution comprising thiosulfate ions, and the washing step is carried out by washing the material with an aqueous solution containing an oxidizing agent capable of reacting with thiosulfate. The oxidizing agent is present in an amount sufficient to precipitate any silver in the solution.

  • Method of processing a photographic product
    Patent number: 5910397
    Abstract: The present invention concerns a novel method of processing a photographic product. In particular, method includes processing a photographic product that comprises a step of surface washing with a solution comprising an oxidizing agent, and a wetting agent. This processing method affords effective washing with a reduced quantity of water.
