Abstract: A flexible belt assembly is prepared by positioning an edge of a belt-shaped substrate in proximity to a metal filled gasket within a groove of a support flange. An electromagnetic force is applied to the gasket to soften the metal to cause conforming of the shape of the gasket to the edge and to the groove. The flexible belt assembly is disassembled by applying a magnetic force to loosen the conforming compression fit.

Abstract: A method of sizing a sleeve of electrically conductive material includes the steps of inserting the sleeve in a die having a seamless inner surface, positioning a magnetic coil inside the sleeve in the die, and sealing the die after the insertion of the sleeve and the positioning of the magnetic coil. A vacuum is created inside the die to avoid air pockets between the outer surface of the sleeve and the inner surface of the die and the magnetic coil is energized to create a magnetic field to expand the sleeve against the inner surface of the die. The process may also be used to form a composite sleeve having an outer layer of material unresponsive to the magnetic field and an inner layer of electrically conductive material.

Abstract: An electroforming process is used to prepare a thin, deformable metal member by immersing an electrode having an outer surface with an undulating cross-section of hill-like and valley-like shapes in an electroforming bath. The hill-like shapes are narrower than the valley-like shapes, and, in a preferred embodiment, the bottoms of the valley-like shapes are electroformed to be thinner than the tops of the hill-like shapes. The metal member is useful as a spring in a fluid bearing such as an air bearing.

Abstract: A backup roller assembly having a plurality of rollers for applying pressure to an inside surface of a photoreceptor web, and a process for making such backup rollers is disclosed wherein a thin walled tube is extruded from a metallic or polymeric material. After extrusion, the tubing is cut to a desired length and filled with a filler, preferably a urethane foam for providing support for the thin-walled tubing, for the adhesion of journals at each end of the tube and for grounding the photoreceptor web. After the journals are attached at each end of the tubing by the adhesion of the foam, the backup roller can be ground to a precise outer diameter. In a final step, the journals are machined to the proper specifications.

Abstract: An apparatus for gripping a sheet includes a first gripping member and a second gripping member. The second gripping member includes a base which is movable relative to the first gripping member. The second gripping member further includes a plate which is secured to the base, the plate being adapted to cooperate with the first gripping member to grip the sheet.

Abstract: A helical spring is disclosed for transporting developer material in an electrostatographic printer. The helical spring rotates within a conduit for transporting developer from a toner dispenser cartridge to the developer toner roll, or from a cleaning station adjacent the photoreceptor to a waste bottle. The spring can be made of twisted or braided wires coated with a protective coating.

Abstract: An apparatus is provided for fusing marking particles onto a support member. One preferred embodiment of the fusing apparatus includes a journal member, the journal member including a shaft and a base with the shaft and the base being coupled. The fuser apparatus further includes a roller member having opposing ends, the roller member defining a shoulder near an end of the roller member. A retaining member is provided for retaining the base adjacent the shoulder so that at least a portion of the base is in substantial contact with the shoulder. Additionally, a heating device is provided to fuse the marking particles onto the support member when the support member with marking particles is brought into contact with the rolling member.

Abstract: Electroformed and/or electroplated iron with superior ferro-magnetic properties is prepared by an electrolytic process wherein the iron is deposited from an electrolyte bath containing iron salts and preferably substantially free of carbon. The bath and its environment are substantially free of oxygen and other oxidizing agents. A titanium-palladium alloy is a preferred electrode upon which to deposit the iron.

Abstract: An apparatus which generates timing pulses in an electrophotographic printing machine. A flexible member having spaced, marks formed photographically thereon is mounted on the shaft of the photoconductive member to rotate in unison therewith. As the flexible member rotates, the spaced marks are detected to generate a timing pulse output in response thereto. The detector prevents the member from deflecting to control the axial motion of the flexible member during the rotation thereof.
