Disclosed is a method, apparatus and system of drying wet toner particles which includes the use of cooling fluid. The method also includes introducing a heated drying gas into a toner drying chamber to create a circulating flow of drying gas.

Method, apparatus and system for fluid cooling of toner dryer

The process provides an expandable chuck with a variable diameter bulb having a variable wall thickness, the chuck being operatively designed to stretch the bulb to reduce its diameter for insertion into a photoreceptor pipe and upon relaxation to the compress the bulb so as to increase its diameter. The design provides a universal chuck to reduce the cost of changing to different diameter chucks in accommodating different size photoreceptors during the coating and drying process.

Expandable chuck

Disclosed is a venting assembly for a dip coating system, a dip coating system utilizing such venting assembly, and related method for dip coating. These aspects are particularly directed for the production of organic photoconductor layers in imaging devices, and more particularly to drum photoreceptors. The venting assembly eliminates or significantly reduces coating defects otherwise occurring in the production of drum photoreceptors. Also disclosed are the drum photoreceptors produced by this assembly, apparatus and coating process.

Venting assembly for dip coating apparatus and related processes

An assembly and method is described as employing a polymeric plug member. The plug member is used in the bottom portion of a photoreceptor drum to prevent leakage of the coating solution into the interior of a photoreceptor drum during dip-coating.

Photoreceptor plug to enable universal chuck capability

The process provides an expandable chuck with a variable diameter bulb having a variable wall thickness, the chuck being operatively designed to stretch the bulb to reduce its diameter for insertion into a photoreceptor pipe and upon relaxation to compress the bulb so as to increased diameter. The design solves provides a universal chuck to reduce the cost of changing to different diameter chucks in accommodating different size photoreceptors during the coating and drying process.

A method for dip coating the exterior surface of a hollow substrate having an open first end and an open second end, the method including:

Coating method using hollow chuck head

It is desired to remove matter on a fluid surface of a tank. The tank defines a circular tank orifice comprising a tank orifice rim, the tank orifice rim containing a fluid surface of a fluid, the fluid overflowing the tank orifice rim to form a fluid overflow, the fluid surface defining a fluid surface center. The matter is removed by discharging from near the tank orifice rim a plurality (n) of jets of the fluid towards the fluid surface center. Any matter on the fluid surface is thereby urged toward the tank orifice rim and eventually removed from the fluid surface by the fluid overflow. In one application, the tank comprises a dip tank and the fluid comprises photoreceptor coating solution or components thereof such as solvents, additives, or both.

Apparatus and method for removing matter on a fluid surface of a tank

This invention relates to an electroforming device and a process used to electroform a metal layer on an inner surface of a female mandrel. The electrolytic solution flows only through an electrolytic solution passageway that defines the inner surface as the walls of the passageway. The mandrel may include more than one electrolytic solution passageway, or multiple mandrels may be used in a sequential order to mass produce the electroforms.

Electroforming process

There is disclosed an apparatus for depositing metal on a member comprising: (a) a first electrode comprising a first corrugated side; (b) a second electrode having the same polarity as the first electrode and comprising a second corrugated side, wherein the second corrugated side is disposed opposite the first corrugated side, and spaced therefrom; (c) a channel defined by the first corrugated side and the second corrugated side for movement of the member therebetween, wherein the channel has a plurality of alternating expansive areas and constrictive areas; and (d) a conveyor device for transporting the member through the channel.

Apparatus for electrodeposition

A chuck assembly defining a longitudinal axis for internally holding a hollow substrate is disclosed including: (a) a stationary top pressing member; (b) a bottom pressing member movable along the longitudinal axis; (c) an elastic bag defining an opening, a top region, a side wall, and a bottom region, wherein the bag is stretchable along the longitudinal axis and a portion of the top region adjacent the side wall is immobilized against the stationary top pressing member during the stretching of the bag and a portion of the bottom region is coupled to the bottom pressing member; and (d) a width changing apparatus movable along the longitudinal axis, wherein the width changing apparatus is operatively coupled to the bottom pressing member.

Chuck assembly

There is disclosed a carrier system for carrying a substrate batch including:

Substrate carrier system

There is disclosed a chuck assembly defining a longitudinal axis for internally holding a hollow substrate having an open first end and a second end including: (a) an alignment shoulder positioned along the longitudinal axis; (b) an end portion, positioned along the longitudinal axis, that is adapted to be inserted into the substrate through the open first end and comprised of a polymeric member, wherein the polymeric member has a changeable width including a smaller width to permit insertion of the polymeric member into the substrate and a larger width to contact the polymeric member with the substrate inner surface, and the polymeric member is moveable along the longitudinal axis; and (c) a width changing apparatus operatively coupled to the polymeric member, wherein the polymeric member, which is in contact with the substrate inner surface, pulls the substrate a distance along the longitudinal axis towards the alignment shoulder when the polymeric member moves towards the alignment shoulder.

Chuck assembly having a pull up feature

There is disclosed a dip coating apparatus including: (a) a single coating vessel capable of containing a batch of substrates vertically positioned in the vessel, wherein there is absent vessel walls defining a separate compartment for each of the substrates; (b) a coating solution disposed in the vessel, wherein the solution is comprised of materials employed in a photosensitive member and including a solvent that gives off a solvent vapor; and (c) a solvent vapor uniformity control apparatus which minimizes any difference in solvent vapor concentration encountered by the batch of the substrates in the air adjacent the solution surface, thereby improving coating uniformity of the substrates.

Dip coating apparatus having a single coating vessel

A chuck assembly for engaging the inner surface of a hollow substrate including: (a) a body defining a hole, wherein the hole is positioned to be in communication with the air inside the substrate; and (b) a gas pressure regulating apparatus coupled to the hole for regulating the gas pressure inside the substrate.

Chuck assembly having a controlled vent
