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.

Coating apparatus and processes thereof

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.

Intermediate transfer member comprising charge transport layer

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.

Apparatus and method for coating photoreceptor substrates

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.

Liquid charging method and apparatus

Coating apparatus

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.

Coating apparatus including insert device

Multipurpose draft shield apparatus

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.

Coating method and apparatus with substrate extension device

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).

Method for purging stagnant coating solution

A &ldquo;drelt&rdquo; photoreceptor particularly for use in high speed production color printers employing a lightweight porous machinable mandrel made of a foam material as a means of mounting a flexible belt photoreceptor on a rigid and lightweight cylindrical base. This porous foam&mdash;like cylinder is provided with means to temporarily decrease its circumference in order to mount the flexible belt on it. The foam material can be any material that can be formed into a foam type solid structure and then machined to certain precision. Examples of such foam material include a metal foam, a polymer foam, a ceramic foam or a carbon foam.

Immersion coating system

Apparatus and process for fabricating an electrostatographic imaging member assembly including providing a hollow electrostatographic drum having a first end and a second end, the first end having a surface selected from the group consisting of an uncoated surface, a surface coated with only a first component of a multiple component adhesive, a surface coated with only a second component for the multiple component adhesive, the second component containing a fluorescent tracer which fluoresces when irradiated with activating radiation, and a surface coated with a mixture of the first component and the second component containing the fluorescent tracer, directing activating radiation at the surface of the first end, detecting the amount of fluorescence emitted from the surface of the first end, and generating a signal which is substantially proportional to the intensity of fluorescence emitted from the surface of the first end, the signal ranging through at least three levels of strength, the first level representing an uncoated surface or a surface coated with only the first component, the second level representing a mixture of the first component and the second component containing the fluorescent tracer, and the third level representing only the second component containing the fluorescent tracer.

Mounting electrostatographic end flange

An apparatus for centering and holding a substrate including: (a) a substrate holding assembly defining a centerline; and (b) a substrate centering assembly including an alignment member, wherein the alignment member is disposed concentric with the centerline and has an inclined surface that is inclined in a direction such that upon sliding contact of the substrate with the inclined surface, the substrate moves toward the centerline.

Centering and holding apparatus and method using inclined surface

A coating method using an endless, hollow substrate in the shape of a belt or cylinder having an outer surface, an inner surface, a first end, and an open second end, including: (a) depositing via dip coating a first coating solution over the outer surface of the substrate and simultaneously over the inner surface by permitting the first coating solution to flow through the second end to be deposited on the inner surface, thereby depositing a first layer over the outer surface and the inner surface; and (b) depositing via dip coating a second coating solution over the first layer on the outer surface of the substrate and simultaneously over the first layer on the inner surface by permitting the second coating solution to flow through the second end to be deposited on the first layer on the inner surface, thereby depositing a second layer over the outer surface and the inner surface, wherein the first layer and the second layer are deposited over all of the outer surface and the inner surface of a predetermined section of the substrate, wherein the first coating solution and the second coating solution are selected from the group consisting of a charge generating solution, a charge transport solution, an adhesive layer solution, and a charge blocking layer.
