  • Patent number: 6376091
    Abstract: An article includes a substrate and a composite material bonded to the substrate. The composite material includes a matrix consisting of a metallic alloy having a solidus temperature of at least about 700° C. and a plurality of unstabilized zirconium oxide particles distributed throughout the metallic alloy. The article is prepared by combining a precursor of the metallic alloy and the mass of unstabilized zirconium oxide powder to form a mixture, and applying the mixture as a heterogeneous composite material to a substrate to form the article. The step of applying occurs at an application temperature of greater than the solidus temperature of the metallic alloy.

  • Patent number: 5389226
    Abstract: A nickel tungsten-containing coating is electrodeposited onto a substrate from an electrodeposition bath having in solution from about 0.034 to about 0.047 moles per liter of nickel, from about 0.15 to about 0.28 moles per liter of tungsten, from about 0.13 to about 0.43 moles per liter of hydroxycarboxylic acid, and 0 or from about 0.077 to about 0.15 moles per liter of boron. The bath has a pH of from about 6 to about 9, and the electrodeposition is preferably accomplished at a temperature of from about 100.degree. F. to about 140.degree. F.

  • Patent number: 5030519
    Abstract: A matrix-bonded carbide-containing material of high hardness is prepared using a mixture containing a matrix alloy having a composition in weight percent of from about 15 to about 45 percent chromium, from 0 to about 3 percent silicon, from about 2 to about 6 percent boron, from about 3 to about 11 percent titanium (either as metal or as a compound), balance iron and impurities, and a mass of tungsten carbide particles, the tungsten carbide particles preferably being present in an amount of from about 15 to about 60 percent by weight of the total mixture and the matrix alloy preferably being present in an amount of from about 85 to about 40 percent by weight of the total mixture. The matrix alloy is melted to produce a flowable mixture having a liquid phase and solid tungsten carbide particles, and thereafter solidified. During melting, the tungsten carbide particle size is reduced by interaction with the liquid phase.

  • Patent number: 4608319
    Abstract: An extended surface area amorphous metallic article and process for preparation thereof, wherein a homogeneous amorphous metallic alloy is phase-separated to produce two interconnected, internally continuous, amorphous phases, and then one phase is removed. Preferably, the homogeneous metallic alloy has a composition associated with a eutectic between at least two solid solutions. Phase separation is accomplished by exposing the alloy to a temperature which is below the crystallization temperature and also below the phase separation temperature for that composition. Removal of one phase may be accomplished by leaching in a liquid solution, or by vaporization. The resulting article has an extended surface area of the amorphous phase that is not removed. A porous membrane having extended internal surface area may be prepared by continuing the removal process to the removal of one phase throughout the entire thickness of the article.

  • Patent number: 4576715
    Abstract: A membrane pack is constructed, which includes a highly porous carrier sandwiched between a pair of membrane structures that must be kept continuously wet, the pack having a hole and being sealed around the hole to prevent the passage of polluting liquid lying in the hole, into the porous carrier of the pack. The membrane pack is constructed by impregnating the carrier with a flowable polymer which can solidify, to leave a thin layer of the polymer on either surface of the carrier, and by then welding the polymer layers to membranes at either face of the carrier. Ultrasonic welding of the membrane structures to the carrier is performed while the membrane structures are wet, the ultrasonic welding dissipating moisture lying at the interface between the carrier and membrane structures to permit even hydrophilic polymers to be utilized.

  • Patent number: 4557836
    Abstract: A particle discharge mechanism is described for use on a centrifugal dewatering system, which is of relatively simple and rugged construction. The discharge mechanism includes a pair of concentric ring-like gates (50, 52 in FIG. 2) that can move across a particle discharge passageway (46) extending around a rotating vessel (14). The gates are operated in a sequence to first trap a mass of particles inside the radially outermost gate (52), to close an innermost gate (50) to isolate the trapped particles, and then to open the outermost gate (52) to release the trapped mass. In one procedure, the outermost gate is opened only slightly prior to complete particle release, to remove small amounts of remaining water in the mass of particles.

  • Patent number: 4529668
    Abstract: An electrodeposition process for depositing a boron-containing amorphous metallic layer onto a cathode from an electrodeposition bath having borophosphoric acid, dimethylamineborane or diethylamineborane; an ammonium salt of a hydroxycarboxylic acid or amino acid; and a source of the metallic ions. In one embodiment, tungsten-cobalt-boron amorphous alloys are deposited onto the cathode from a bath having borophosphoric acid, an ammonium salt of a hydroxycarboxylic acid or amino acid, a tungsten-containing salt and a cobalt-containing salt. In the preferred embodiment, the tungsten-containing salt is sodium tungstate, the cobalt-containing salt is cobalt sulphate, and the ammonium salt of a hydroxycarboxylic acid is ammonium citrate or ammonium tartrate.

  • Patent number: 4246108
    Abstract: A centrifugal microstrainer includes a closed cylindrical vessel with a cylindrical screen within, both rotating about a hollow shaft forming a common central axis. Liquid-solid admixture introduced through the shaft is flowed radially outward subjected to centrifugal acceleration, and forced back through the screen under pressure with particles too large to pass the screen remaining on its outboard side. The centrifugal force applied by the rotation of the vessel acts on these larger particles pushing them away from the screen thus preventing clogging and permitting substantially continuous operation. The device may be operated as a classifier by providing a plurality of concentric screens of decreasing mesh size spaced outwardly from one another in conjunction with properly sized chokes.

  • Patent number: 4132649
    Abstract: A fluid purification apparatus of the type which includes a stack of membrane packs and a stack of gaskets located at the peripheral portions of the membrane packs to keep them separated from one another, wherein the gaskets have outer lands bearing on one another and surrounding the membrane packs, inner lands pressing against the faces of the packs to seal against them, and elongated bendable middle gasket portions connecting the inner and outer lands to allow the inner lands to adjust position so as to compensate for variations in thickness of the membrane packs.
