  • Patent number: 6733912
    Abstract: A first fixture of a transportable fixture apparatus incorporates a substantially porous first region adapted to receive one or more porous and/or non-porous first material layers, such as fuel cell layers, and to facilitate formation of a vacuum between the first fixture and the first material layers. A second fixture incorporates a substantially porous second region adapted to receive one or more porous and/or non-porous second material layers and to facilitate formation of a vacuum between the second fixture and the second material layers. A stop arrangement protrudes from one or both of the first and second fixtures, and is situated peripheral to the first and second material layers when the first and second fixtures are brought into contact. The stop arrangement defines a cavity adapted to effect compression of the first and second material layers when the first and second fixtures are brought into contact.

  • Patent number: 6720131
    Abstract: The invention relates to the development of lithographic printing plates and comprises the application of a thin film of developer solution to each plate in a controlled manner using a jetting printhead which scans the plate to apply the developer solution as the plate is conveyed under the jetting printhead. Sensors and control means activate and deactivate the scanning jetting printhead in response to the presence or absence of a plate. The developer is allowed to dwell on the plate as it is conveyed across a support structure for a sufficient time to allow for percolation into and/or dissolution of the soluble areas of the coating and is then washed off and sent to waste.

  • Patent number: 6692904
    Abstract: A photographic washing bath comprises a chamber containing a wash solution for a silver halide photographic material having a pH of less than 7 and comprising water having dissolved therein an oxidizing agent, said oxidizing agent having an oxidizing potential of at least 1 volt and being in a concentration of from 0.05 to 2 Molar. The oxidation potential of the oxidizing agent is preferably at least 1.2 volts and may be hydrogen peroxide or a source of hydrogen peroxide, a persulphate, a perborate, a bromate, or an iodate. A washing process using the invention is suitable for being carried out in same chamber as the development and fixing stages in which case hydrogen peroxide is the preferred oxidizing agent because any peroxide remaining at the end of the wash stage can be removed by evaporation, thereby avoiding risk of contamination of the next stage to be carried out in the chamber.

  • Patent number: 6689550
    Abstract: A photosensitive media cartridge includes an ambient condition sensor mounted in the cartridge for sensing ambient conditions in the cartridge. When the cartridge is positioned at a media transfer position on an image-forming device that permits the conveyance of media from the cartridge to the image-forming device, image development or printing on the media in the image-forming device is controlled based on the sensed ambient conditions in the cartridge. The ambient condition sensor includes a cover layer and a conductive layer, wherein a rate of response to ambient conditions of the cover layer matches rate of response to ambient conditions of the photosensitive media to be developed. As a further option, the media itself can include a conductive layer so that the media can be the sensor.
