  • Patent number: 4895737
    Abstract: An MOCVD deposition technique wherein the pressure of reagent vapors within the reaction vessel (1) is maintained at a reduced pressure in the range 10.sup.-2 to .about.10 millibars and contained mounted substrates (15) are heated non-inductively e.g. by an electric resistance circumferential furnace (5). In the above pressure range, high diffusivity of the reagent vapors ensures exposure of the substrates (15) to a uniform reagent mixture. A large number of substrates (15) may be processed simultaneously. As heating is non-inductive, an inert mounting (17) can be utilized avoiding the introduction of contaminants (e.g. carbon) into the deposited film.

  • Patent number: 4895739
    Abstract: A method for metal plating the surface of an article formed from an organic plastic. The method includes a step of passing a current between two electrodes immersed in an electrolyte containing dissolved plating metal. One of the electrodes is the article to be plated and is provided with a surface having areas of a catalytic metal chalcogenide conversion coating adjacent to and in contact with conductive areas. In a preferred embodiment, the catalytic metal chalcogenide conversion coating is formed by treating the article with an acid colloidal solution of a tin-noble metal electroless metal plating catalyst and, subsequently, treating with a solution containing a dissolved sulfide to form a sulfide of the noble metal. The conversion coating allows the article to be directly electroplated. The method is especially useful for the formation of printed circuit boards and is sufficiently versatile to permit formation of a printed circuit board by a process that involves pattern plating.

  • Patent number: 4895745
    Abstract: A pressure-sensitive adhesive tape can be produced by photopolymerization and yet its pressure-sensitive adhesive layer can have a dark appearance when it contains a pigment or dye plus finely divided hydrophobic silica. As compared to a tape which is identical except for omission of the hydrophobic silica, the adhesive layer of the tape is substantially darker and usually of substantially more intense color. Furthermore, the tape exhibits better adhesive properties than do otherwise identical tapes containing no silica. The pressure-sensitive adhesive preferably is an acrylic pressure-sensitive adhesive and may be filled with glass microbubbles which afford a foamlike appearance and character.

  • Patent number: 4895748
    Abstract: A flocked polyurethane foam fabric and method for manufacturing the same for which flock fibers imbedded in an adhesive on the foam are permanently flattened and entangled. Dry ink is transferred onto the flock fibers at the same time that flattening of the fibers is taking place. The flock fibers are thermally set into their flattened state along an outer surface of a polyurethane foam base of the fabric. Flattening the flock fibers causes the entanglement of the flock, thereby improving the hand, appearance, drapeability, abrasion resistance, water repellency and heat insulation qualities for apparel items over that of unflattened flock fibers.

  • Patent number: 4895754
    Abstract: Use of surface modification treatment on mineral fines to obtain higher filler loadings in asphalt used for roofing shingles. Mineral fines are coated with oil such as a petroleum oil at about the 0.25-1.0 percent level before they are incorporated into molten asphalt. This treatment makes minerals which otherwise would be uncompetitive with traditional fillers, such as limestone, sufficiently compatible with asphalt to be a viable alternative to limestone.

  • Patent number: 4895760
    Abstract: Covering a rigid but pliable, smooth surface with a one-sided matte embossed polyethylene film, where the non-embossed smooth side of the film is in direct contact with the smooth surface being covered. Adhesion of the smooth side of the film to the smooth surface to which it is applied is effected much like a vacuum adhesion as seen when a drop of water is placed between two sheets of glass. The embossed side of the film forms microscopic air pockets when rolled upon itself which prevents blocking. This feature allows the non-embossed side to be made as smooth as possible without the need for an anti-blocking agent.

  • Patent number: 4895769
    Abstract: A stainable polymeric sheet material adapted to the production of a light polarizer therefrom is provided by a method, according to which, a support sheet of amorphous polymeric material is uniaxially stretched in a first direction (at or above the glass transition temperature of the polymeric support material), a layer of polyvinyl alcohol (PVA) is coated from an aqueous PVA-containing composition onto the uniaxially stretched support material, and the PVA-coated uniaxially stretched polymeric sheet material is stretched along a second direction, at an angle within about .+-.60 degrees to a normal to the first direction of stretch. The method provides a material which can be converted, by incorporation of visible dichroism into the PVA layer, to a light polarizer which combines efficient light polarizing properties and good mechanical strength and resistance to fracture along the stretch directions.

  • Patent number: 4895770
    Abstract: The invention relates to a process for the manufacture of multi-layered wear-resistant CVD- or PVD-coatings applied to hardmetal parts containing WC-Co or WC-Ni, where at least one of the layers is a metal-boronitride layer. According to the invention, the boron concentration in the metal-boronitride layer is maintained below the critical level above which in addition a homogeneous boronitride mixed crystal phase a further phase, particularly a diboride phase is formed. A non-boronic, or only slightly boronic, intermediate layer is employed as a diffusion barrier between the hardmetal and the metal-boronitride layer to limit or prevent the formation of brittle tungsten cobalt boron or tungsten nickel boron phases on the external surface of the hardmetal. The metallic boronitride layer can be applied either as a single layer or in multiple layers alternating with other mechanically resistant layers. The hardmetal part is particularly a cutting insert for machining.

  • Patent number: 4895771
    Abstract: A surface for providing an electrically conductive surface coating on an electrical contact body. The process resulting in such a coating comprises the steps of depositing upon the body surface in sequence, (a) a nickel layer, (b) a first gold layer, (c) a palladium/nickel alloy layer which may be an alloy containing nickel up to a proportion of 50% by weight, and (d) a second gold layer. All the layers may be deposited by an electrodeposition process.The resulting surface coating has excellent corrosion and wear resistance properties.

  • Patent number: 4895773
    Abstract: The invention provides a rechargeable electrochemical power storage cell. The cell has an anode compartment defined between a cell casing and a separator, the anode compartment containing active anode material which is liquid at the operating temperature of the cell. The separator defines a cathode compartment containing an electrolyte which is liquid at the operating temperature of the cell, and an active cathode material. The separator separates said compartments from each other and during discharge of the cell the active anode material passes from the anode compartment to the cathode compartment through the separator, to enter the cathode compartment in ionic form. The active anode material passes through the separator from the cathode compartment to the anode compartment during charging of the cell.
