  • Patent number: 4286039
    Abstract: A deformable polyurethane roller, which may be either a squeegee roller or a blotting roller, is positioned to contact a liquid-developed electrostatic image on a photoconductor. The polyurethane roller has a resistivity of 10.sup.9 ohm-centimeters or less and a Shore A hardness of 45 or less. The roller is biased by a potential having a sign the same as the sign of the charged toner particles in a liquid developer which comprises an insulating liquid having charged toner particles disseminated therethrough. The bias on the polyurethane roller is such that it prevents streaking, smearing, tailing or distortion of the developed electrostatic image and removes so much of the liquid carrier of the liquid developer from the surface of the photoconductor that the just-moist developed image can be transferred to a carrier sheet. This enables a higher-boiling insulating liquid to be used as the carrier liquid in a liquid developer.

  • Patent number: 4275282
    Abstract: A support mechanism for a rotatable wafer-support susceptor adapted for rotation by a shaft in a vertical orientation. The support mechanism comprises a quartz pedestal tube resting with frictional engagement on a metallic table fixed to the shaft. The pedestal supports, with frictional engagement, the base of the susceptor and is rotated by frictional engagement with the table. Means disposed within an aperture of the base and within the tube constrain the base, and thus the susceptor, and the tube to symmetrical rotation about the shaft passing through a centrally located aperture in the base.

  • Patent number: 4271783
    Abstract: An elongate electrical conductor is continuously coated with electrostatically charged powder by passing the conductor upwardly through a tube into the upper portion of a container having a charged fluidized bed of the powder in a lower portion thereof. The tube extends upwardly through the bed and the tube height is adjusted relative to the upper surface of the bed to control the thickness of the powder coating. An array of electrodes having associated switches permits application of uniform coatings to conductors having a variety of shapes. Two or more conductors may be uniformly coated from the same fluidized bed in a container having a baffle which divides the upper portion into two or more compartments and spaced apart tubes extend upwardly into the different compartments.

  • Patent number: 4267794
    Abstract: Apparatus for coating articles with enamel slip comprises an evacuatable container 1, which is divided in a vertical plane into parts 2, 3, which are movable toward and away from each other. The articles 29 to be coated are suspended in a row from an endless conveyor track and are introduced into the container 1 when its parts 2, 3 have been moved apart to open the container 1. The container 1 is then closed. In the closed container, the suspension means are held between soft seals 12, 13 which cover the confronting edges of the container parts 2, 3. When the container 1 has been closed, the air contained therein is sucked off and slip is sucked into the container. As soon as the coating operation has been completed, the slip is drained from the container 1 and the latter is then opened and the coated article is removed.

  • Patent number: 4266506
    Abstract: A new technique for producing uniform layers of solid DT on microballoon surfaces. Local heating of the target, typically by means of a focused laser, within an isothermal freezing cell containing a low pressure cryogenic exchange gas such as helium, vaporizes the DT fuel contained within the microballoon. Removal of the laser heating source causes the DT gas to rapidly condense and freeze in a layer which exhibits a good degree of uniformity.

  • Patent number: 4267248
    Abstract: A magnet-brush development process in which the amount of developer powder supplied to a development zone is self-controllable by the rotation of a magnet roll. A permanent magnet member and the shell rotate at different speeds in the same direction in such a manner that developer powder, as a whole, is conveyed on the shell in the direction opposite to the rotation of the magnet roll from a doctor spacing of a developer vessel to an image-bearing material. By controlling the doctor spacing to be larger than the gap between the image-bearing material and the magnet roll, an accumulation of the developer powder occurs on the shell between the doctor spacing and the development zone and is kept to be substantially constant. At the accemulation, an understream of powder moves in the direction of roll-movement towards the powder supply.
