Patent number: 6983104Abstract: 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: September 18, 2002Date of Patent: January 3, 2006Assignees: Guardian Industries Corp., Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A.

Patent number: 6939576Abstract: Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol of polymer solution to a substrate and substantially simultaneously applying an energy source to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.Type: GrantFiled: June 27, 2001Date of Patent: September 6, 2005Assignee: nGimat Co.Inventors: Girish Deshpande, Andrew Tye Hunt, Subramaniam Shanmugham, Eric J. Yurtkuran, Todd Polley, Miodrag Oljara, Tzyy-Jiuan Jan Hwang, Aimee Poda, George Neuman

Patent number: 6926967Abstract: A heat treatable coated article including a solar management layer for reflecting infrared (IR) or the like, is provided between a substrate and an overlying dielectric layer. An underlying dielectric layer between the substrate and solar management layer is optional. In certain embodiments, the solar management layer may include NiCrNx while the dielectric layer(s) may include a nitride such as silicon nitride. By nitriding the solar management layer, it has been found that the resulting coated article is more color stable upon heat treatment (HT). For example, the coated article may have a ?E* value (transmissive and/or glass side reflective) of no greater than 5.0, more preferably no greater than 4.0, and most preferably no greater than 3.0. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windows, or the like.Type: GrantFiled: February 13, 2004Date of Patent: August 9, 2005Assignee: Guardian Industries Corp.Inventors: George Neuman, Grzegorz Stachowiak, Hong Wang

Publication number: 20050145480Abstract: A coated article is provided so as to have a fairly high visible transmission (TY or Tvis) to sheet resistance (Rs) ratio (i.e., a ratio Tvis/Rs). The higher this ratio, the better the coated article's combined functionality of providing for both good solar performance (e.g., ability to reflect and/or absorb IR radiation) and high visible transmission. In certain example embodiments, coated articles herein may be heat treatable. Coated articles herein may be used in the context of insulating glass (IG) window units, architectural or residential monolithic window units, vehicle window units, and/or the like.Type: ApplicationFiled: March 1, 2005Publication date: July 7, 2005Applicant: Guardian Industries Corp.Inventors: George Neuman, Philip Lingle, Ronald Laird, Thomas Seder, Grzegorz Stachowiak

Patent number: 6797388Abstract: A coating in accordance with the invention has a substantially crystalline first layer with a substantially crystalline second layer provided over the first layer. A breaker layer is provided between the first and second layers and is configured to prevent or at least reduce epitaxial growth of the second layer on the first layer. A color suppression layer may be provided below the first layer. The coating can be provided on a substrate to make a coated article. A method of coating a substrate includes depositing a substantially crystalline first layer over at least a portion of the substrate and depositing a breaker layer over the first layer. The breaker layer is configured to prevent or at least reduce epitaxial growth of a subsequently deposited layer on the first layer.Type: GrantFiled: March 9, 2000Date of Patent: September 28, 2004Assignee: PPG Industries Ohio, Inc.Inventors: Janos Szanyi, John F.

Publication number: 20040180214Abstract: A sputter coated article is provided with improved mechanical durability (e.g., pre-HT scratch resistance) and/or thermal stability by sputtering at least one Ag inclusive layer in an atmosphere including at least O2 gas. For instance, in certain example embodiments an Ag inclusive target may be sputtered in an atmosphere including a combination of Ar and O2 gas.

Publication number: 20030215644Abstract: Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol (N) of polymer solution to a substrate (30) and substantially simultaneously applying an energy source (38) to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame (38) that may optionally or desirably deposit material along with the polymer spray.

Publication number: 20030180546Abstract: A coated article is provided so as to include a solar control coating having an infrared (IR) blocking (reflecting and/or absorbing) layer sandwiched between at least a pair of dielectric layers. The IR reflecting layer includes chromium nitride (CrxNy) in certain example embodiments. The use of chromium nitride enables the coated article to have good corrosion resistance to acid(s), good mechanical performance such as scratch resistance, and/or good color stability (i.e., a low &Dgr;E* value(s)) upon heat treatment (HT). The coated article may be heat treated (e.g., thermally tempered) in certain example embodiments of the invention.Type: ApplicationFiled: January 29, 2003Publication date: September 25, 2003Applicant: Guardian Industries Corp.Inventors: Grzegorz Stachowiak, George Neuman, Hong Wang

Patent number: 6601776Abstract: The present invention involves controlled atomization of liquids for various applications such as part/droplet seeding for laser-based measurements of flow velocity, temperature, and concentration; flame and a plasma based elemental analysis; nano-powder production; spray drying for generation of small-sized particles; nebulizers in the production of sub-micron size droplets and for atomizing fuel for use in combustion chambers. In these and other atomizer applications the control of droplet and/or particle size is very critical In some applications extremely small droplets are preferred (less than a micron), while in others, droplet diameters on the scale of several microns are required. The present invention has the flexibility of forming droplets within a particular range of diameters, wherein not only the size of the average droplet can be adjusted, but the range of sizes may be adjusted as well. The atomizer (4) itself is in the form of a heated tube (44) having an inlet end (48) and an outlet end (50).Type: GrantFiled: June 6, 2002Date of Patent: August 5, 2003Assignee: MicroCoating Technologies, Inc.Inventors: Miodrag Oljaca, Andrew Tije Hunt, Brian T.
