  • Patent number: 4618504
    Abstract: Small, preferably micronsized hollow glass or ceramic spheres or foaming agents for making such micronsized hollow spaces or voids are incorporated into a resin material which is formed into a layer and after curing of the resin layer, it is abraded, sand or grit blasted so as to rupture the outermost layer of spheres or voids to provide a plurality of undercuts or nooks and crannies. A thermally sprayed metal, such as copper, becomes embedded into the undercuts pores, nooks and crannies, such that the bond or adherent strength is greatly improved. This micronsized glass, ceramic spheres and/or pores greatly increases the bond strength by providing better undercuts in the surface to be sprayed by molten metal and provide the capability of depositing thicker layers without jeopardizing the bond.

  • Patent number: 4617222
    Abstract: A process and product is presented for obtaining selective areas of distinctive appearance, i.e., matting on synthetic coverings. The process includes, depositing a polymeric coating which contains at least one radiation initiator for polymerization onto at least a first selected area or zone on an expandable or non-expandable support substrate. Next, at least one second coating comprised of a crosslinkable monomer is deposited onto a second selected area on the substrate. This second area or zone may encompass at least a portion of the first area. Thereafter, pre-gelling is performed on the deposited material followed by a graining operation which is carried out over at least a portion of the substrate surface. The synthetic covering in the first zone or area is then polymerized by radiation initiation wherein the particular appearance thereof is fixed to the substrate. Thereafter, gelling is carried out wherein the polymer which has not been fixed by radiation initiation will flow, i.e.

  • Patent number: 4613519
    Abstract: A method for recording and storing information in a hydrogenated amorphous silicon device, comprising: depositing hydrogenated amorphous silicon on a substrate to form a charge-collection device; and generating defects in the hydrogenated amorphous silicon device, wherein the defects act as recombination centers that reduce the lifetime of carriers, thereby reducing charge-collection efficiency; and thus in the charge-collection mode of scanning probe instruments, regions of the hydrogenated amorphous silicon device that contain the defects appear darker in comparison to regions of the device that do not contain the defects, leading to a contrast formation for pattern recognition and information storage, in the device, which darkened areas can be restored to their original charge-collection efficiency by heating the hydrogenated amorphous silicon to a temperature of about 100.degree. C. to 250.degree. C. for a sufficient period of time to provide for such restoration.

  • Patent number: RE32244
    Abstract: A coating of wear resistant tungsten carbide is applied to a photo-etched roto-gravure cylinder, the coating having a thickness in the range of from 15 to 35 microns. Tungsten carbide powder is supplied to a plasma flame spray gun by means of a powder feeder which supplies powder particles at a uniform density and at given sizes. The feeder comprises a hopper having air inlet and outlet passages and vertically spaced porous membranes which confine the powder and permit the passage of air. Air flow through the hopper suspends the powder particles of a desired diameter range adjacent a spray gun feed conduit. When copper cylinders are to be coated, the surface is allowed to oxidize to promote a chemical bonding of the coating to the surface.
