  • Patent number: 4084896
    Abstract: A photoelectrophoretic imaging machine for producing, in a preferred embodiment, full color copies from opaque originals or, alternatively, copies from transparencies.In a preferred embodiment, the formation of photoelectrophoretic images occurs between two thin injecting and blocking webs at least one of which is partially transparent and the image formed is transferred to a paper web. The injecting and blocking webs may be disposable, thus, cleaning systems are not required. The injecting web is provided with a conductive surface and is driven in a path to the inking station where a layer of photoelectrophoretic ink is applied to the conductive web surface. The inked injecting web is driven in a path passing in close proximity to a deposition scorotron at the precharge station and into contact with the blocking web to form the ink-web sandwich at the imaging roller in the imaging zone.

  • Patent number: 3968271
    Abstract: A coating apparatus in which a coating material is passed from an internal reservoir through a narrow orifice to a surface to be coated. At the end of the orifice the apparatus has two surfaces which are adjacent the surface to be coated, one of which is closer to the surface to be coated and functions as a metering surface. A reservoir of coating material is built up between the other surface and the surface to be coated and coating material is metered therefrom. The apparatus is particularly suited for applying an imaging suspension to an electrode of a photoelectrophoretic imaging system.
