Abstract: A method for fabricating an electrically heatable coated transparency, particularly useful as a vehicle windshield, is disclosed. The method involves sputtering on a substrate surface layers of metal oxide, metal-containing primer, infrared reflective metal, metal-containing primer and metal oxide to produce an electroconductive coating, and applying first and second bus bars to the substrate in contact with the coating.
Abstract: Organic-inorganic hybrid polymers and a method of making them by reaction of organic monomers with organofunctional alkoxysilanes are disclosed.
Abstract: A solid-state electrochromic device is disclosed comprising tungsten oxide-Prussian blue complementary configuration in combination with a proton-conducting polymer electrolyte.
Abstract: Oil-in-water microemulsion cleaning compositions comprising four principal components are described. These four components are a terpene solvent, e.g., d-limonene, an aliphatic glycol monoether co-solvent, e.g., dipropylene glycol monomethyl ether, a mixture of non-ionic surfactants selected from (1) a capped alkylphenol ethoxylate or an ethoxylated higher aliphatic alcohol, and (2) a fatty acid alkanolamide, and water. The cleaning composition may be used in concentrated form or in a diluted form. The composition may be used for cleaning soil from among others glass and metal parts.
Abstract: Novel transparent complementary electrode materials for electrochromic cells are disclosed, of the general formula [M.sup.1 ].sub.4 [M.sup.2 (CN).sub.6 ].sub.3 wherein M.sup.1 may be indium, gallium, gadolinium, lanthanum, and M.sup.2 is iron. Unlike Prussian blue (where M.sup.1 and M.sup.2 are both iron), the complementary electrode materials of the present invention are stable, and do not have to be precharged.
Abstract: An ultraviolet radiation resistant coating is disclosed comprising a hydroxy-containing organic UV absorbing compound such as hydroxybenzotriazole which comprises hydrophilic moieties such as ethoxylate or propoxylate so that the compound is miscible and reactive with an inorganic oxide matrix formed by hydrolysis and condensation of an alkoxysilane and/or other metal alkoxide.
