Patent number: 7082260Abstract: An apparatus and method for bending and/or tempering glass substrate(s) are provided. The amount of near-IR radiation which reaches the glass to be bent and/or tempered is limited (e.g., via filtering or any other suitable technique). Thus, the IR radiation (used for heating the glass) which reaches the glass to be bent and/or tempered includes mostly mid-IR and/or far-IR radiation, and not much near-IR. In such a manner, coating(s) provided on the glass can be protected and kept at lower temperatures so as to be less likely to be damaged during the bending and/or tempering process. Heating efficiency can be improved. A ceramic (e.g., aluminosilicate) filter or baffle may be used in certain embodiments in order to reduce the amount of mid-IR and/or far-IR radiation reaching the glass to be tempered and/or bent.Type: GrantFiled: August 25, 2005Date of Patent: July 25, 2006Assignees: Guardian Industries Corp., Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A.

Publication number: 20060159933Abstract: A coated article is provided so as to include a solar control coating having an infrared (IR) reflecting layer sandwiched between at least a pair of dielectric layers. The IR reflecting layer may be of or include NbZrOx, NbZr, NiCr, NiCrNx, or the like in certain embodiments of this invention. In particular, a zirconium silicon oxynitride (e.g., ZrSiOxNy) inclusive layer is provided which unexpectedly improves blocking (reflecting and/or absorption) of UV radiation in a manner which does not significantly degrade other optical properties of a coated article. Moreover, the ZrSiOxNy also has been found to improve (lower) the ?E* value upon heat treatment, thereby permitting a coated article when heat treated (HT) to more closely match its non-HT counterpart with respect to glass side reflective color after such HT.Type: ApplicationFiled: January 19, 2005Publication date: July 20, 2006Applicants: C.R.V.C., Guardian Industries Corp.Inventors: Bernd Disteldorf, Anton Dietrich, Ratchaneekorn Chonlamaitri

Publication number: 20060144697Abstract: A coated article includes a coating which has a zinc oxide inclusive layer provided as a contact layer under and directly contacting an infrared (IR) reflecting layer of a material such as silver. It has been found that the emissivity (or emittance) of the coated article can be reduced by sputtering a cast target(s) to form the zinc oxide inclusive contact layer—as opposed to sputtering a target formed by plasma spraying or the like. Thus, it has unexpectedly been found that the emissivity and/or resistivity of an IR reflecting layer can be improved (i.e., lowered) by using a cast target to sputter-form the contact layer located immediately under the IR reflecting layer.Type: ApplicationFiled: January 6, 2005Publication date: July 6, 2006Applicant: Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A.

Publication number: 20060083934Abstract: A method of making a coated article is provided, where the coated article may be used in a window or the like and may have at least one infrared (IR) reflecting layer in a low-E coating. The IR reflecting layer may be of silver or the like. In certain example embodiments, at least krypton (Kr) gas is used in sputter-depositing a silver inclusive IR reflecting layer. It has been found that the use of Kr gas in sputtering Ag targets results in an IR reflecting layer having improved resistance and emittance properties.Type: ApplicationFiled: January 18, 2005Publication date: April 20, 2006Applicant: Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A.

Publication number: 20060077580Abstract: A mirror (e.g., first surface mirror) is provided with a layer of or including chromium nitride (CrNx). In certain example embodiments, the CrNx layer may be the primary reflective layer of the mirror. Surprisingly and unexpectedly, it has been found the addition of nitrogen to the chromium to form CrNx reduces pinhole formations in the resulting layer. In certain example embodiments, the more nitrogen which is introduced into the layer, the smaller the number and/or size of pinholes in the Cr inclusive layer. In certain example embodiments, it has also been found that the addition of nitrogen to Cr may improve durability.Type: ApplicationFiled: October 7, 2004Publication date: April 13, 2006Applicants: Guardian Industries Corp., C.R.V.C.Inventors: Francis Wuillaume, Anton Dietrich, Brent Boyce, Gregory Scott

Publication number: 20060046074Abstract: A coated article is provided with a low-emissivity (low-E) layer stack for use in a window unit or the like. The layer stack, or coating, may permit the coated article to achieve one or more of a fairly low solar factor (SF) value, a high selectivity (Tvis/SF) value, substantially neutral color at normal and/or off-axis viewing angles, and/or low emissivity. When high selectivity values are achieved, there is provided a high ratio of visible transmission to SF, which is a desirable feature in certain example instances. In certain example embodiments, a sub-oxide layer (e.g., NiCrOx) may be used as a contact layer under an infrared (IR) reflecting layer in order to permit low SF values, high selectivity, and good coloration to be achieved.Type: ApplicationFiled: November 30, 2004Publication date: March 2, 2006Applicant: (C.R.V.C.)

Coated article with oxidation graded layer proximate IR reflecting layer(s) and corresponding method
Publication number: 20050258029Abstract: A coated article is provided that may be heat treated in certain example embodiments. A graded layer (e.g., contact layer or other suitable layer) is formed by initially sputter-depositing a layer, and thereafter ion beam treating the sputter-deposited layer with at least reactive gas ions in order to form a graded layer. In certain example embodiments, the result is a coated article that has improved visible transmission and/or durability, without sacrificing optional heat treatability.Type: ApplicationFiled: May 18, 2004Publication date: November 24, 2005Applicants: Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A.
