  • Patent number: 5597386
    Abstract: A hair dye consisting of an anti-hair antibody immobilized on a high bulky coloring material. The coloring material may be a coloring substance such as an inorganic pigment, water-soluble coloring matter, or water-insoluble coloring matter, or a composite of the coloring substance and a macromolecular carrier. Since it provides a good and strong coloring capability specific to hair, the hair dye of the present invention will neither stain the skin nor cause skin irritation. Further, the touch and feel of the hair will be improved.

  • Patent number: 5316046
    Abstract: High performance hoses are disclosed which are characterized by enhanced heat resistance, leading to prolonged service life, and hence are suitable for use in automobile power steering units. Inner tubes are formed of hydrogenated acrylonitrile/butadiene copolymer rubbers of a selected composition. The inner tubes may be of a double-layered construction composed of an inner layer of hydrogenated acrylonitrile/butadiene copolymer rubber and an outer layer of rubber composition which comprises specified amounts of a selected class of sulfurs, organic peroxide and triazine compounds combined with selected sulfur-curable base rubbers.

  • Patent number: 5297337
    Abstract: Rubber compositions are disclosed for integral attachment of polymeric and metallic materials. Improved bondability is attributed to the use of a selected base rubber blended with a selected class of inorganic or organic fillers, silane compounds and vulcanizing agents such that the finished composition is provided with a specified range of Mooney viscosities. Also disclosed is a method of hose-metal fitting connection by the application of the composition. Gas- and oil-impermeability characteristics are greatly enhanced.

  • Patent number: 5077108
    Abstract: Composite laminates are disclosed which are designed to exhibit superior resistance to oil and to heat and which are comprised essentially of a rubbery layer and a fibrous layer bonded thereover. The rubber layer is formed from a rubber composition made up of highly hydrogenated acrylonitrile-butadiene rubber, an organic peroxide curing agent and magnesium oxide, and the fibrous layer is formed from an organic fiber treated with a dip coating of a specified composition. Also disclosed is a composite hose in which the rubbery layer is utilized as an inner tube and the fibrous layer as a reinforcement.

  • Patent number: 5068137
    Abstract: Composite laminates are disclosed which are designed to exhibit superior resistance to oil and to heat and which are comprised essentially of two different rubbery layers and a fibrous layer interposed therebetween. One rubber layer is formed from a rubber composition made up of highly hydrogenated acrylonitrile-butadiene rubber, an organic peroxide curing agent and magnesium oxide, and the other from a rubber composition of a rubber other than chlosulfonated polyethylene rubber. The fibrous layer is formed from an organic fiber treated with a dip coating of a specified composition. Also disclosed is a composite hose in which the rubbery layers and fibrous layer are assembled.

  • Patent number: 4802938
    Abstract: A process for producing hoses of laminated construction having a plastic inner tube is disclosed which comprises:- (a) extruding a thermoplastic resin on a mandrel to form an inner tube with a predetermined thickness, the mandrel being preformed of a thermoplastic resin or rubber and releasable from the inner tube, (b) laminating an outer tube integrally on the inner tube by extrusion of an unvulcanized rubber to form an integral hose body, (c) vulcanizing the hose body, (d) removing the mandrel from the vulcanized hose body. This hose is characterized by high resistance to load of impulse.

  • Patent number: 3992578
    Abstract: A yoke mounting apparatus for adjustably positioning a yoke relative to a cathode ray tube and maintaining it in position until it is secured to the tube. The yoke is fastened to an elongated member rotatably mounted on a positioning means that can be moved along three orthogonal axes. A tilting mechanism supporting the tube allows tilting of the tube relative to the yoke. A locking means normally prevents any movement between the yoke and tube. A pneumatic source is used to release only that lock preventing the type of movement desired. All the controls for the apparatus are mounted at the front of the tube so the tube screen can be viewed while the relative positions of the yoke and tube are adjusted.
