Patent number: 6730373Abstract: An index-matching coating is applied directly to a low-emissivity (“lowE”) thin-film coating. Nodules growing from a site in the lowE coating are removed to avoid propagation of defects through the layers of the index-matching coating. A tempering step in an oxygen-containing atmosphere produces compressive stress in the lowE coating and hardens the coating. The compressive stress facilitates removal of the nodules and the hardening allows mechanical cleaning of the lowE coating prior to the index-matching coating, further removing nodules. Magnesium-fluoride is used as the final layer of the index-matching coating in one embodiment to improve abrasion resistance. The resulting glass panel may be used as a display panel in a plasma display or an organic light-emitting diode display, for example.Type: GrantFiled: November 21, 2001Date of Patent: May 4, 2004Assignee: Optical Coating Laboratory, Inc.Inventors: Brad A.

Resistive elements on diamond can be fabricated by adding conductive components to a borosilicate glass.Type: GrantFiled: April 9, 2002Date of Patent: April 20, 2004Assignee: Morgan Chemical Products, Inc.Inventor: Ronald R.

Publication number: 20030207113Abstract: A flake-based pigment is provided having improved specular reflectance characteristics in the visible wavelength range. The flake-based pigment has a plurality of composite reflective flakes each formed of a support layer and a reflector layer on one or both opposing sides of the support layer. This flake structure exhibits a uniaxial compressive strength much greater than a corresponding uniaxial tensile strength. The structure of the flakes provides the benefits of rigidity and brittle fracture during manufacture and application processes, which ultimately provides favorable planar and specular reflectance characteristics to the pigment in the visible wavelength range. A variety of outer coating layers can be formed around the composite reflective flakes, such as various dielectric and/or absorber layers, to produce desired optical characteristics in the pigment.Type: ApplicationFiled: March 27, 2003Publication date: November 6, 2003Applicant: Flex Products, Inc.Inventors: Kent E. Coulter, Thomas Mayer, John S. Matteucci, Mary E. Matteucci, Roger W. Phillips

Publication number: 20030198816Abstract: A heat treatable coated article (e.g., vehicle windshield, IG unit, etc.) is provided with a dual-silver low-E coating. Before and/or after heat treatment (HT), the coating and/or coated article has a visible transmittance of at least 70%, more preferably at least 75%. Moreover, the coating and/or coated article is designed so as to have approximately the same color when viewed over a wide range of viewing angles. In certain embodiments, at least one contact layer (e.g., of or including NiCrOx) that contacts an infrared (IR) reflecting layer (e.g., Ag) is oxidation graded so that it progressively becomes less oxidized through its thickness as it nears the IR reflecting layer. In still other embodiments, a Si-rich silicon nitride layer(s) may be utilized to reduce haze.Type: ApplicationFiled: June 4, 2003Publication date: October 23, 2003Applicants: Guardian Industries Corp., Centre Luxembourgeois de Recherches pour le Verr et la Ceramique S.A.
