Abstract:
A seamed or seamless intermediate transfer member comprising a layer having an oxidized charge transport molecule, a charge transport molecule, or mixtures thereof, wherein in the seamed embodiment, the seam adhesive may also include an oxidized charge transport molecule, a charge transport molecule, or mixtures thereof.
Abstract:
An apparatus including: a tank with a closed base end and an open top end, and adapted to contain a coating formulation; and a receiver member with at least a cone shape, where the base of the cone is attached to the interior and to the base end of the tank and adapted to receive an article for coating.
Abstract:
A coating method for a hollow substrate including: (a) forming a seamed extended substrate unit composed of a substrate extension device and the substrate, and employing a chuck assembly to internally grip the substrate; (b) dip coating the extended substrate unit while the chuck assembly internally grips the substrate to deposit a layer first on the substrate extension device and then on the substrate; and (c) separating, subsequent to the dip coating the extended substrate unit, the substrate extension device from the substrate.
Abstract:
A method comprising: (a) overflowing a vessel with a coating solution, wherein there is a zone of stagnant coating solution within the vessel; (b) directing at least one fluid jet at the zone of the stagnant coating solution, thereby causing at least a portion of the stagnant coating solution to overflow the vessel; and (c) dip coating a substrate with the coating solution in the vessel, subsequent to the feature (b).
Abstract:
A method including: (a) dispensing an electrically conductive liquid into a contact member permeable to the liquid; (b) rubbing the contact member and a surface against each other, at a contact length greater than a tangential contact length, to release the liquid from the contact member to wet the surface with the electrically conductive liquid in a layer ranging in thickness from about 1 to about 100 micrometers; and (c) electrifying the liquid at any time effective for imparting an electrical charge to the surface.

Abstract:
An apparatus for coating a photoreceptor substrate, such as a photoreceptor belt or a photoreceptor drum, consists of at least one photoreceptor coating fluid reservoir or diptank. The diptank defines an inlet at one end and a conduit with an orifice at the other end. The conduit includes at least one porous element such as a grid, screen or mesh arranged for suspending a plurality of layers of non-contaminating rounded objects, such as stainless steel or glass beads, in the bottom of the conduit. Photoreceptor coating solution supplied to the inlet is thereby forced to flow through the plurality of layers of beads prior to coating a photoreceptor substrate that is inserted through the orifice. As a result, the uniformity of the coating solution is improved as it coats the photoreceptor substrate, thereby reducing coating defects in the finished photoreceptor belt or drum.

Abstract:
An apparatus including: (a) a vessel for a solution having a bottom end and an open top end, and defining a vertical axis perpendicular to the bottom end; (b) an insert device having a bottom surface and a top surface and nested within the vessel, wherein the insert device defines a passageway dimensioned for a substrate which is parallel to the vertical axis and extending through the insert device, and wherein the insert device also defines at least one bypass channel extending through the insert to allow solution within the vessel to flow to the top surface of the insert device; and (c) an overflow container positioned adjacent the vessel to catch solution runoff from the top surface of the insert device.
