摘要:
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.
摘要:
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.
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.
摘要:
A lighting fixture includes a directional light source that produces a plurality of light rays. An optical module is coupled to the directional light source to focus the plurality of light rays into a beam of light rays to be output by the lighting fixture. The angular distribution of a majority of the beam relative to a vector normal to a ceiling on or near which the fixture is to be installed is in a range of 70 to 95 degrees. A blocking structure is used to block a direct view of the beam of light when the fixture is installed such that only indirect light is primarily visible from a viewer at least in or around a working plane substantially parallel to the ceiling.
摘要:
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.
摘要:
A truck tire/wheel assembly detection system in which the moving thermal dynamics of a truck are measured before cooling off, by passing over and around contact or non-contact thermometers directed toward the tire/wheel assembly and transmits the approximate temperature of each tire/wheel assembly to a computer which will compares the output data and identifies each abnormally overheated tire/wheel assembly and print out location on rig and other information that may be required. A modem controlled by the computer is used to advise other interested parties of rig condition at this check out point.
摘要:
A method of rendering nonreflective an imaging member substrate, preferably a photoreceptor substrate, involves etching the substrate with(a) an effective amount of an etching agent at a temperature sufficient to effect etching of the substrate, wherein the etching agent comprises (i) high purity deionized water, (ii) a mixture of high purity deionized water and a mild acid or (iii) a mixture of high purity deionized water and a base; or(b) a combination of the etching agent (a) and modulating ultrasonic energy.This method renders the substrate clean, spotless, and pristine, and provides it with uniform surface roughness.
