Patent number: 8794033Abstract: Certain example embodiments of this invention relate to apparatuses for sealing the tips of pump-out tubes of vacuum insulating glass (VIG) units, and/or associated methods. In certain example embodiments, a laser source used in sealing the pump-out tube is thermally insulated from the VIG unit and emits a laser beam through one or more windows in an oven towards a mirror located therein.

Publication number: 20140182774Abstract: Vacuum-insulated glass windows include two or more glass panes, and glass-bump spacers formed in a surface of one of the panes. The glass-bump spacers consist of the glass material from the body portion of the glass pane. At least one of the glass panes comprises chemically-strengthened glass. Methods of forming VIG windows include forming the glass-bump spacers by irradiating a glass pane with a focused beam from a laser. Heating effects in the glass cause the glass to locally expand, thereby forming a glass-bump spacer. In embodiments where the glass-bump spacers are formed in a chemically-strengthened glass pane, the glass-bump spacers may be formed before or after the chemical strengthening. A second glass pane is brought into contact with the glass-bump spacers, and the edges sealed. The resulting sealed interior region is evacuated to a pressure of less than one atmosphere.Type: ApplicationFiled: March 6, 2014Publication date: July 3, 2014Applicant: CORNING INCORPORATEDInventors: Richard Robert Grzybowski, Michael S.

Patent number: 8758532Abstract: An device for simultaneous application of elastoplastic spacer tapes to two glass panes with identical outline shape and identical dimensions has two application heads (107) that can be adjusted essentially vertically up and down on linear axles (105).

Publication number: 20130323441Abstract: A vacuum insulated glass (VIG) window assembly and method for making same is provided in which a variation in the final edge seal height is preferably 0.20 mm or less, more preferably about 0.15 mm or less. Controlling final edge seal height variations substantially reduces breakage of the glass substrates of the VIG window assembly during vacuum pump-down of the cavity between the glass substrates. Edge seal height variation may be controlled, for example, by controlling initial dispensing of green frit material, controlling temperature variations during firing, and/or controlling cycle times during firing.Type: ApplicationFiled: May 31, 2012Publication date: December 5, 2013Applicant: Guardian Industries Corp.Inventors: Timothy A.

Publication number: 20130316099Abstract: A stand-off is necessary to separate two glass lites (panes of glass) in a vacuum insulated glazing system. This stand-off must provide sufficient mechanical support to keep the lites apart despite one atmosphere pressure pushing the lites together. For systems that are designed with flexible edge seals, there will be movement of one lite relative to the other during diurnal cycling, and the stand-offs will therefore be scraped against at least one of the lite surfaces. Because many mechanically robust materials suitable for stand-offs have high friction, it is beneficial to apply a lubricant to the surface of the stand-off. However, it is also beneficial to adhere the stand-off to one lite during the manufacturing operation, and this need opposes the need for good lubricity. This invention describes means for optimizing the composition of a stand-off to meet these conflicting needs.Type: ApplicationFiled: March 14, 2013Publication date: November 28, 2013Applicant: EVERSEALED WINDOWS, INC.Inventors: SETH A.

Publication number: 20130306222Abstract: A method for making a vacuum insulated glass window assembly is provided in which an amount of wet frit material is applied to a lower portion of a pump-out tube prior to insertion of the tube into a hole formed in a glass substrate of the VIG window assembly. The tube is then inserted into the hole, frit paste end first. An amount of frit may overflow the hole and form a bump/shoulder of frit material proximate the area of the hole on an outer surface of the glass substrate. Applying the fit to the tube prior to insertion and at a lower portion thereof reduces the amount of and/or avoids residual frit being deposited in an area of the tube that might significantly interfere with subsequent sealing processes, such as, for example, laser sealing of the pump-out tube.Type: ApplicationFiled: May 18, 2012Publication date: November 21, 2013Applicant: Guardian Industries Corp.Inventors: Timothy A.

Publication number: 20130302543Abstract: Certain example embodiments relate to techniques for sealing insulating glass (IG) units via an adhesive. The adhesives of certain example embodiments may be applied to the inner surface(s) of the substrates that form the IG unit and/or an outer surface of the spacer, without first priming and/or cleaning the surface(s). These adhesives may be silanol-inclusive moisture-cured adhesives. In certain example instances, the adhesive may be moisture-cured at ambient or other conditions such that the component and the substrate are adapted to survive large temperature fluctuations and vibrational shocks.Type: ApplicationFiled: March 4, 2013Publication date: November 14, 2013Applicant: GUARDIAN INDUSTRIES CORP.Inventors: Duane O. RECKER, Keith ALDRICH

Publication number: 20130292038Abstract: Disclosed is a method for vacuum acquisition during the manufacturing of a vacuum glass component, which specifically comprises the following steps: glass sheets (1, 3) constituting the vacuum glass component are placed in a vacuum environment having desired degree of vacuum, wherein all the glass sheets (1, 3) are in the vacuum environment independent of each other prior to assembling and ultimate sealing, thus a vacuum space inside the assembled vacuum glass component has exactly the same degree of vacuum as the vacuum environment. Therefore, the degree of vacuum of the processed vacuum glass component can be guaranteed by only controlling the degree of the vacuum environment, thereby avoiding problems existed-in the prior art, enhancing the processing efficiency of the vacuum glass component and also ensuring the quality of the vacuum glass component.Type: ApplicationFiled: August 17, 2011Publication date: November 7, 2013Applicant: LUOYANG LANDGLASS TECHNOLOGY CO., LTDInventors: Yanbing Li, Zhangsheng Wang

Patent number: 8530011Abstract: A low-e insulating glass unit has a suspended, coated IR reflecting polymer sheet under tension, e.g. from heat shrinkage. The polymer sheet is coated with a multilayer stack of dielectric and metallic layers, including at least one silver layer deposited upon a zinc oxide seed layer that is at most 15 nm thickness. The use of zinc oxide ensures good seeding for high quality silver layer growth, thereby providing low emissivity. The thinness of the zinc oxide ensures that it resists cracking when the polymer sheet is tensioned.Type: GrantFiled: December 13, 2010Date of Patent: September 10, 2013Assignee: Southwall Technologies Inc.Inventors: Ronny Kleinhempel, Julius G. Kozak, Roland C. Thielsch, Richard T. Wipfler, Christian H. Stoessel, Lee C. Boman
