  • Patent number: 4042346
    Abstract: A diamond or cubic boron nitride grinding wheel in which an abrasive section comprising abrasive grits distributed through and held by a phenolic resin matrix is bonded to a non-abrasive core, is improved, in terms of ease of manufacture and elimination of cracking or poor adhesion, by means of a core composition which includes between 5 and 20% by volume of a thermoset resin selected from the group consisting of phenol aldehyde, urea formaldehyde, and melamine formaldehyde resins, particulate metal and graphite, and the remainder being a resin selected from the group consisting of epoxy resins, addition polymers of unsaturated polyesters, and thermosetting polyimide resins, in the range of from 5 to 80% by volume of the core.

  • Patent number: 4042347
    Abstract: A metal-resin composite material consisting of a continuous metal matrix and a continuous resin matrix fabricated by hot-pressing a mixture of precursors, the precursors for the metal matrix including an elemental metal having a melting point below 450.degree. C, the metal matrix including an intermetallic compound or alloy having a melting point above 500.degree. C, and the continuous resin matrix being fabricable at a temperature above 250.degree. C. Such composite materials have particular utility as a bonding matrix for premium abrasives such as diamond and boron nitride, to form grinding tools.

  • Patent number: 4021529
    Abstract: Silicon oxynitride, Si.sub.2 ON.sub.2 is made, without the need for a catalyst such as CaO, by heating a mixture of powdered silica and silicon in an inert atmosphere at a temperature below the melting point of silicon, and subsequently nitriding the mixture to form silicon oxynitride with minimal silicon nitride contamination.

  • Patent number: 4014142
    Abstract: A method and apparatus for conditioning steel by grinding at a constant metal removal rate by monitoring net power and the normal force between the wheel and the workpiece, and adjusting the normal force to achieve a given, predetermined metal removal rate is based on the relation between power and normal force at constant wheel speed. A semi-automatic method, by operator control of the normal force, and a fully automatic method are disclosed. Provision for correcting the force in response to wheel wear is optional.

    Inventor: Loring Coes, Jr.
  • Patent number: 3985842
    Abstract: A molten magnesia is air quenched to provide a very large proportion of solid free flowing spheres of fused magnesia, a large percentage of which are smaller than about 35 Tyler mesh, which may be used directly in electrical resistor units without the necessity of crushing and calcining while the larger sized spheres may be crushed if desired and can be used with the uncrushed spheres without being calcined. The method may employ sea water magnesite or any other source of raw material having a high magnesia content that is cheap and readily available, the product being improved and more easily fused by the addition of small amounts of alumina, silica and calcia to the magnesite as it is being fed to the fusion furnace.

  • Patent number: 3979214
    Abstract: A polycrystalline monolithic sintered alumina refractory body (for use as kiln furniture, and crucibles or nozzles for containment of molten metal) is of fine crystalline sintered aluminum oxide including 15 to 44% by weight of grains of silicon carbide dispersed throughout, such silicon carbide preferably having a sizing between 6 and 46 mesh, but in any case at least 75% being coarser than 100 mesh, such bodies having superior thermal stability and shock resistance.

  • Patent number: 3963458
    Abstract: Coated abrasive material is provided having coated on the adhesive bond a supersize layer which improves grinding and which is stabilized against thermal degradation during use of the abrasive material. This layer comprises an elastomeric material and a sufficient amount of antioxidant to limit oxidative degradation and, in the most preferred embodiment, an active solid, particulate filler. The presence of such a layer on articles manufactured from the coated abrasive material results in a much cooler grinding operation thereby reducing the conditions conducive to metal glazing and resulting in extended coated abrasive product life.

  • Patent number: 3945945
    Abstract: High surface area alumina bodies for use as catalysts, catalyst carriers, and sorbents are made by controlled mixing of fine particle size platy boehmite alumina aggregates with a monobasic acid to produce non-pasty free-flowing particulate mass of aggregates of boehmite. This mass can then be formed by pressure into selected shapes such as rings, saddles, cylinders, solid, or hollow, or pellets, dried and fired to produce bodies of boehmite, gamma alumina, delta alumina, theta alumina or alpha alumina ranging in surface area of from 10 square meters per gram to greater than 300 square meters per gram. Catalytic metal can be included in the bodies by impregnation, before or after firing, or can be incorporated by inclusion in the aqueous acid treating solution.
