  • Patent number: 7074622
    Abstract: The present invention relates to a method of particle separation comprising preparing a suspension of particles containing at least one recognizable target particle in a suspending solution, labeling the target particle with a conjugate marker, wherein the conjugate marker comprises at least one recognition unit for the recognizable target particle and at least one peroxidase enzyme, contacting a gelatin surface with the suspending solution, adding developer to the suspending solution in contact with the gelatin surface and in the presence of phenol to attach the target particle to the gelatin surface, and washing the gelatin surface to remove unattached particles. The method may also include detecting the presence of the target particle on the gelatin surface as well as detaching and recovering the attached particles after removal of the non-target particles.

  • Patent number: 6838233
    Abstract: A method of processing photographic color papers is carried out using a photographic bleach-fixing composition in a bleach-fixing step that is carried out for less than 60 seconds. The bleach-fixing composition comprises certain aliphatic or aromatic sulfur-containing compounds that include a —N?C(SH)— group. The bleach-fixing composition can be prepared from a two-part bleach-fixing kit having two solutions that can be added directly to a processing chamber or premixed to form a replenisher solution.

  • Patent number: 6670108
    Abstract: This invention relates to a method for processing a silver halide color photographic material comprising the steps of loading the material into a chamber adapted to hold the material therein; introducing a measured amount of a color developer solution into the chamber; developing the photographic material with the color developer solution; introducing into the chamber a measured amount of a processing solution which arrests development, without removing the color developer solution, to form a developer/stop solution mixture; processing the photographic material with the developer/stop solution mixture, substantially removing all of the developer/stop mixture solution from the chamber; then providing in the chamber a bleach/fixer solution mixture comprising a bleaching agent and a fixing agent; and processing the photographic material with the bleach/fixer solution mixture; wherein the color developer solution is utilized in the amount of greater than or equal to 375 ml/m2 of the photographic material that is

  • Patent number: 6508598
    Abstract: The present invention relates to a processing system and method for processing photographic material. The processing system and method of the invention is adapted to recover water from humid air for reuse in the processor, as well as convert a liquid waste processing solution into a dry waste for disposal. In the system and method of the present invention, heated air is circulated through the processor and comes into contact with a cold surface to condense the heated air. The water resulting from this contacting of the heated air with the cold surface can be collected and recycled back to the processor for reuse in the processor. Further, waste solution can be absorbed by a matting material appropriately placed in the processor which evaporates the waste solution to a solid waste for subsequent disposal.
