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: An electroforming process for forming a multilayer endless metal belt includes forming increasingly compressively stressed successive layers on a mandrel, and assembling the layers to form a multilayer belt. The belt is particularly useful as a driving member for a continuously-variable transmission.

Abstract: A layered photosensitive imaging member is modified to reduce the effects of interference within the member caused by reflections from coherent light incident on a base ground plane. The modification described is to form the ground plane surface by an electroforming process which leaves the surface with a black finish. Light incident on the ground plane is absorbed, eliminating the reflections which contribute to the interference effect at the imaging member surface.

Abstract: Distortion-free method of mounting an end piece member on a thin-walled hollow tube member, particularly in the assembly of photoreceptor drums and the like, includes the steps of supporting an expandable end piece member within the chamber of an air centering device with its central axis aligned vertically; applying a layer of flowable adhesive to the interior surface of an open end of the hollow tube member; freely suspending the tube member above the end piece member with the open end remaining free of radial distortion and directed toward the end piece member; centering the tube member, by means of the air centering device, to concentrically align the tube member with the end piece member; inserting the end piece member into the tube member; deformingly expanding the end piece member until the layer of flowable adhesive is sufficiently compressed between an outer peripheral edge of the end piece member and the interior surface of the tube member, so as to absorb any dimensional discrepancies therebetween;

Abstract: A specially constructed fuseblock and rail mounting adapter are provided for mounting a fuseblock to a channel. The fuseblock comprises a base having an elongated slot opening therethrough and, on its bottom, a pair of flanges. The adapter comprises a fuseblock mounting side and a channel mounting side. The fuseblock mounting side has a top surface having a key and a pair of locking tabs extending therefrom. The key is adapted to be received by said elongated slot when said fuseblock and adapter are generally perpendicular to each other, and then, upon 90.degree. rotation of the fuseblock relative to the adapter, lock with the elongated slot. The rotation of the fuseblock also causes each pair of locking tabs to engage one of said flanges. The channel mounting side is separately engageable with three different sized rails.

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 electroforming process is used to prepare an electroformed metal layer on the inside surface of a female mandrel to form an electroform with a hollow interior. A device may be positioned within the hollow interior of the electroform, and the interior is filled with a filling material. The electroform may then be separated from the mandrel by a force applied to the device positioned within the filling material.

Abstract: In a multilayer endless metal belt assembly, adjacent opposing belt surfaces have different hardnesses so that they may be lubricous and less subject to galling.

Abstract: A method and apparatus for securing a drum blank for machining includes inserting a cylindrical mandrel within a bore of a drum blank, introducing a liquid support material into a space between the outer diameter of the mandrel and the inner diameter of the drum blank, and solidifying the support material. Once the support material is solidified, the drum blank is securely held to the mandrel. Machining operations can be performed by mounting the assembly in a lathe. After machining is completed, the support material may be treated so that the mandrel can be removed from the drum blank. The mandrel may then be recycled.

Abstract: An endless metal belt assembly is made with opposing adjacent belt surfaces that may contain a roughened surface containing protuberances, indentations and/or pits and are configured such that a lubricant can be held and circulated between the adjacent surfaces. The roughened surface may be formed by an electroforming process in which one or more components of the electroforming bath and the operating parameters of the electroforming bath are adjusted to create the protuberances, indentations and/or pits. A belt assembly formed in this manner is useful as a driving member for a continuously variable transmission.

Abstract: Ductility of belt material is increased at least at one edge of an endless metal belt, thus reducing the likelihood of premature failure of the belt. The inner region of the belt maintains the inherent strength of the metal. The endless metal belt so formed is particularly useful as a driving member for a continuously-variable transmission.

Abstract: A layered photosensitive imaging member is modified to reduce the effects of interference within the member caused by reflections from coherent light incident on a base ground plane. The modification described is to form the ground plane surface with a rough surface morphology by an electroforming process which leaves the surface with a matte-like finish. Light reflected from the ground plane formed with the matte finish is diffused through the bulk of the photosensitive layer breaking up the interference fringe patterns which are otherwise later manifested as a plywood pattern on output prints made from the exposed sensitive medium.

Abstract: A process for preparing a multilayered belt includes providing a mandrel having an outer electroforming surface or an inner electroforming surface; and sequentially electrodepositing both a polymer layer and a conductive layer on the electroforming surface of the mandrel to form a multilayered belt.

Abstract: An electroforming process for forming a multilayer endless metal belt includes submerging a mandrel in an electroforming bath, electroforming a first layer on the mandrel, forming a passive coating on the outer surface of the first layer, and depositing at least one additional layer on the oxide coating. By this process, a multilayer metal belt is formed with non-adhesive layers. The belt may then be cut to the desired width, and is particularly useful as a driving member for a continuously-variable transmission.

Abstract: A method is provided for forming an endless metal belt assembly with specific parameters to reduce friction, increase lubricity, and transmit maximum torque. An endless metal belt of the invention may be formed by an electroforming process, and is useful as a drive member for a continuously variable transmission.

Abstract: The fuse holder for receiving a cylindrical fuse having conductive ends includes a cap having a fuse carrier disposed in part therein for receiving one end of the fuse and a barrel having a fuse cavity for receiving the cap and fuse. The fuse carrier includes a spring retainer for retaining the fuse within the carrier. The barrel includes a bottom terminal extending through the barrel for contact with one conductive end of the fuse and a side terminal having tines extending through apertures in the side of the barrel for engagement with the fuse carrier which in turn is in electrical contact with the other end of the fuse. The body of the side terminal is disposed on the exterior of the barrel and, in conjunction with the wall of the barrel, isolates the interior of the barrel from the body of the side terminal such that only that portion of the side terminal required to complete the electrical path from the fuse carrier to the side terminal is exposed interior the barrel.
