摘要:
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.
摘要:
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.
摘要:
An endless metal belt resistant to failure due to stress induced by bending contains an internal stress gradient of radially outward increasing compressive stress which opposes external stress applied to the belt. The belt can be made by an electroforming process.
摘要:
An endless metal belt resistant to failure due to stress induced by bending contains an internal stress gradient of radially outward increasing compressive stress which opposes external stress applied to the belt. The belt can be made by an electroforming process. While electroforming, at least one operating parameter selected from bath temperature, current density, agitation, and stress reducer concentration is adjusted to cause the internal stress to gradually increase, compressively, from the radially inner surface of the belt to the radially outer surface of the belt. The internal stress preferably increases at a substantially constant rate and may range from about 160,000 psi tensile at the inner surface to about 120,000 psi compressive at the outer surface.

There is disclosed a chuck apparatus for holding and shaping a hollow, flexible, endless substrate during dip coating comprising: (a) a hollow, flexible bladder adapted to be disposed within the substrate; and (b) a first spindle and a second spindle which are partially disposed within the bladder, the second spindle being movable to press the bladder against the substrate and to shape the bladder and the substrate into an elongated shape.

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.

A process including: creating a galvanic cell composed of a substrate as an anode, a cathode, and an electrolytic solution, wherein the substrate includes a metal surface having a plurality of metal fibers connected to the metal surface, wherein the cathode is selected to be more noble than the metal surface resulting in the anode being the working electrode, wherein the galvanic cell spontaneously electrochemically treats the metal surface in the absence of power externally supplied to the galvanic cell; and allowing the spontaneous electrochemical treatment of the metal surface to continue for a time sufficient to sever a number of the metal fibers from the metal surface to result in severed metal fiber fragments unconnected with the metal surface.
摘要:
A method of fabricating a blotter roll for uniformly conditioning liquid images consisting of toner particles and carrier liquid. The method includes electroforming a semi-rigid resilient and perforated metallic substrate for preventing undesirable impressions of substrate outlines and footprints on an image being conditioned. The resilient metallic substrate is electroformed so as to be seamless and to have a cylindrical hollow interior, and first and second open ends. The method next includes forming at least a first absorbent foam layer over the semi-rigid resilient substrate for absorbing carrier liquid from the image being conditioned, and filling the cylindrical hollow interior of the semi-rigid resilient substrate using a porous foam insert for rigidifying the semi-rigid resilient substrate, and for uniformly spreading throughout the hollow interior, vacuum effects on the image being conditioned, of a vacuum source connected to the hollow interior for drawing carrier liquid from the image being conditioned.
