  • Patent number: 6713178
    Abstract: A soda inclusive glass substrate is coated with a highly tetrahedral amorphous carbon inclusive layer that is a form of diamond-like carbon (DLC). In certain embodiments, the amorphous carbon layer includes at least about 35% sp3 carbon-carbon bonds, more preferably at least about 70%, and most preferably at least about 80% of the sp3 carbon-carbon bonds. The high density (e.g. greater than or equal to about 2.4 gm/cm3) of the amorphous carbon layer prevents soda from exiting the glass and reacting with water at surface(s) of the glass, thereby minimizing visible stains (or corrosion) on the glass. The high density amorphous carbon layer also may repel water. In some embodiments, the highly tetrahedral amorphous carbon layer is part of a larger DLC coating, while in other embodiments the highly tetrahedral layer forms the entirety of a DLC coating on the substrate.

  • Patent number: 6713185
    Abstract: A method of forming a reinforced polymer film structure is disclosed that includes the steps of slitting a biaxially oriented polymer film web having a top face and a bottom face into a first portion and a second portion, identifying the first portion and the second portion, and placing the first portion atop the second portion, such that the bottom face of the first portion is adjacent the top face of the second portion. This structure provides an impact and tear resistant laminate. Also disclosed is a method of forming a polymer film structure by identifying a molecular orientation direction profile of two portions of biaxially oriented polymer film and layering the two portions such that a molecular orientation direction profile of one does not coincide with a molecular orientation direction profile of the other.

  • Patent number: 6713188
    Abstract: We have discovered that the formation of particulate inclusions at the surface and the interior of an aluminum alloy article interferes with the performance of the article when a surface of the article is protected by an anodized coating. We have also discovered that the formation of such particulate inclusions can be controlled to a large extent by controlling the concentration of particular impurities present in the alloy used to fabricate the aluminum alloy article.

  • Patent number: 6713190
    Abstract: A method is described for making a reinforcing wire frame for embedding in a moulded polymer support frame over which woven wire cloth is to be stretched and secured to form a sifting screen. The method involves locating lengths of cut wire substantially equally spaced apart in a jig to form a first array. A second array of lengths of cut wire is located over the first array with the lengths of wire in the second array being substantially at right angles to those of the first array. The lengths of wire in the first and second arrays are resistance welded at points of mutual intersection so as to form a first substantially rectilinear matrix.
