Latest Patents

Lundberg holds a patent for a "Method of and apparatus for joining edges of glass sheets." This patent describes a process for fabricating an insulated glass unit formed from a pair of glass sheets. One of these sheets features an electroconductive coating. The method involves positioning the first sheet on a vacuum support while the second sheet is spaced above it to prevent arcing during electrical heating. The marginal edges of the second sheet are heated to a temperature that causes sagging, allowing the two sheets to be joined by fusion. A strip heater is utilized to maintain the temperature of the edges, ensuring a successful bond. After the sheets are joined, they are annealed, and an insulating gas is introduced into the airspace before sealing the pore hole.
