  • Patent number: 6815005
    Abstract: There is disclosed a method for permanently and decoratively enhancing a polyethylene surface of a preformed article. In this method, a decorative enhancement composition is created by blending particulate thermoplastic powder, a binder solid, and a colorant into a liquid carrier. The particulate thermoplastic powder bonds to the colorant, the binder solid promotes adhesion of the colored thermoplastic to the polyethylene surface until it can be bonded, and the liquid carrier facilitates the transfer of the colored thermoplastic to the polyethylene surface of the preformed article. The decorative enhancement composition is applied to the polyethylene surface. The deposited decorative enhancement composition and the interfacing polyethylene surface are heated sufficiently to incorporate the decorative enhancement composition into the polyethylene surface. The enhanced polyethylene surface is allowed to cure by removal of the application of heat.

The welding rod essentially comprises a first layer which is substantially formed from a consolidated layer having pigmented particles and a second layer which is substantially formed from a consolidated layer of clear particle. The three dimensional welding rod includes three dimensional pigmented particles which appear to be dispersed about the clear particles and having an excess of clear upon forming the seam.

  • Patent number: 6815042
    Abstract: A floor covering made up of at least two layers bonded to one another, including a bottom layer (2) of electrically conductive rubber arranged under a light-colored top layer (1) of rubber, where the top layer (1) is interrupted in partial areas distributed over its area in a pattern, and formed by electrically conductive rubber there. The top layer (1) is produced from a powder (1.1) of first particles (1.2) that are light in color and made of electrically insulating rubber, as well as second particles (1.3) embedded in it, which are made of electrically conductive, at least partially vulcanized rubber. The second particles (1.3) have a diameter D, determined by screen analysis, that is at least as great as the thickness D1 of the top layer and, for practical purposes, not greater than the total of the thicknesses of the top layer and the bottom layer D2. The first (1.2) and the second (1.3) particles are pressed together and to the bottom layer (2), without pores, and bonded by vulcanization.

  • Patent number: 6815043
    Abstract: A method of making a polymer coating on a microstructured substrate. The method may be performed by vaporizing a liquid monomer or other pre-polymer composition and condensing the vaporized material onto a microstructured substrate, followed by curing. The resulting article may possess a coating that preserves the underlying microstructural feature profile. Such a profile-preserving polymer coating can be used to change or enhance the surface properties of the microstructured substrate while maintaining the function of the structure.

  • Patent number: 6815044
    Abstract: The acoustic characteristics of lightweight multilayer construction panels have been improved by the formation of three-dimensionally meandering curved slots or rows of slot sections in the core of the panels. The slot depth varies along the length of the curved slots. The slots or rows of slots are spaced from each other by an on-center spacing that is preferably constant along the length of the slots.

  • Patent number: 6815045
    Abstract: Provided is a method for manufacturing a metal powder by providing a reducing solution by dispersing caustic alkali, and hydrazine and/or hydrazine hydrate into a solvent; providing a metal salt solution comprising a salt of electroconductive metal, a rare earth metal salt and a solvent; and mixing the reducing solution with the metal salt solution to form a metal powder by depositing a hydroxide derived from the rare earth metal salt and by reducing the salt of electroconductive metal. With this metal powder manufacturing method, the sintering of the metal powder is restricted at a low temperature, the sintering initiation temperature is shifted to a higher level, and rapid sintering shrinkage is restricted, while ceramic grain growth is not accelerated.

  • Patent number: 6815047
    Abstract: A foamed thermoplastic resin sheet has a foaming ratio of not less than 2.5, and cells, existing in an interior part which extends inward from a depth of 20 percent a whole thickness of the sheet from the front and rear surfaces thereof respectively in a thickness direction thereof and from 15 percent a width of the sheet from both side edges respectively, satisfy the following expressions (1) and (2): 0.5≦D/C≦0.9  (1) 0.5≦E/C≦0.9  (2) where C represents a mean cell diameter in the thickness direction of the foamed thermoplastic resin sheet, D represents a mean cell diameter in an extrusion direction (MD) of the same, and E represents a mean cell diameter in the width direction (TD) of the same. The foamed thermoplastic resin sheet thus arranged has a high foaming ratio, and is formed thick.

  • Patent number: 6815049
    Abstract: A composition including, but not limited to, a mixture of a calcium sulfate material, water, and a tetrametaphosphate compound is disclosed. Desirably, the inclusion of the tetrametaphosphate compound (e.g., salt or ion) in a pre-set treatment of a calcium sulfate material enhances the resistance to permanent deformation (e.g., sag), dimensional stability, and/or compressive strength of the composition while also preferably avoiding any significant retardive effect on the rate of hydration of calcined gypsum to calcium sulfate dihydrate. A set gypsum-containing product and a method for producing a set gypsum-containing product having increased resistance to permanent deformation are also disclosed.
