Publication number: 20210371333Abstract: The present disclosure relates to a method of applying a seal material on a glass sheet surface of one or more tempered glass sheets for a vacuum insulated glass unit. The method comprises the steps of: obtaining by means of a sensor system (4) surface variation data of at least one tempered glass sheet (3, 30) for said a vacuum insulated glass (VIG) unit, and applying seal material (2) for an edge seal at a surface (3a, 30a) of said one or more tempered glass sheet (3, 30) by means of one or more nozzles (5) having a nozzle opening (6) for dispensing said seal material. The method further comprises by means of a control system (7) controlling one or more adjustment systems (9, 10, 11) influencing on the applying of said seal material by said one or more nozzles (5) based on said obtained surface variation data.Type: ApplicationFiled: November 5, 2019Publication date: December 2, 2021Inventors: Annette Johncock KRISKO, Peter SØNDERKÆR, Karsten Hansgaard NIELSEN, Henrik Aslak Jensen, Timothy Alan Dennis

Patent number: 10465433Abstract: Certain example embodiments of this invention relate to vacuum insulating glass (VIG) units having improved seals made using two different frit-based edge seal materials, and/or methods of making the same. In certain example embodiments, a first frit material is applied around peripheral edges of first and second glass substrates. The first frit material, which may be bismuth-based in certain example embodiments, is fired with a heat treatment (e.g., thermal tempering) process. A second frit material, which may be VBZ-based in certain example embodiments, is applied and at least partially overlaps with the fired first frit material. The first frit material acts as a primer, and the second frit material helps seal together the VIG unit. The second frit material is fired at a significantly lower temperature that enables the glass to retain the temper or other strength imparted by the heat treatment.Type: GrantFiled: January 27, 2017Date of Patent: November 5, 2019Assignee: GUARDIAN GLASS, LLC.Inventors: John P. Hogan, Timothy Alan Dennis, Rudolph Hugo Petrmichl, Greg Kemenah

Patent number: 8668798Abstract: Certain example embodiments of this invention relate to a frit slurry paste for use in assemblies (e.g., a vacuum insulated glass unit or a plasma display panel), and methods of making the same. Frit powder, binder material, and a water-based solvent are mixed together to form an intermediate mixture. The frit powder is substantially lead free, and the water-based solvent is provided at a first temperature. Additional water-based solvent is added to the intermediate mixture to form a frit slurry paste. The additional water-based solvent is provided at a second temperature, with the second temperature being lower than the first temperature. The binder material is provided at a concentration of 0.001%-20% by weight with respect to the frit slurry paste or the frit slurry paste absent the frit powder. The frit slurry paste has a bulk viscosity of 2,000-200,000 cps.Type: GrantFiled: June 30, 2009Date of Patent: March 11, 2014Assignee: Guardian Industries Corp.Inventors: David J.
