Problems solved by technology

[0007] The differential movement of the glazing at the corners creates complex behavior in the seal with a lateral shear component, possibly causing wrinkling or breaking of the foil
Additionally, gaps in the continuity of the foil and sudden changes in foil thickness at overlaps tend to create leak paths

example 1

[0066] Example 1: Square pieces of aluminum window screen were cut 9 inches by 9 inches and mounted concentrically on clean, untempered 10 inches by 10 inches soda lime glass such that these square Almost have a common center. Two layers of 1100 series aluminum foil, a 2 mil layer and a 1 mil layer, were placed together so that they could be simultaneously cut into 12" x 12" squares.

[0067] The double foil assembly is mounted on top of the screen with a common center to create equal foil overhang at each pane edge. The annular area of ​​the glazing that is only covered by the foil but not the screen can be used to provide a location for the weld line. This stacked assembly was mounted on the table top (used as an anvil) of a custom designed 100 watt ultrasonic seam welder.

[0068] A single continuous weld line is manufactured to weld the foil to the side glass surface adjacent the edge of the glazing, the weld line following a straight weld path except at the corners wher...

example 2

[0070] Example 2: From the test assembly produced in Example 1, the foil and screen were removed from the inside area of ​​the closed circular weld, leaving only a continuous and jointless double layer of foil welded to the outside edge of the 10 inch square window pane strip. According to a co-pending patent application, a clean 12-inch by 12-inch soda-lime glazing with a low-E coating sputtered on one side is disposed on its coated surface about 125 microns thick and arranged in a 20 mm by 20 Several metal spacers in a grid pattern of millimeters. The 10 inch square glass and foil assembly is laid on top of the spacer of the 12 inch square windowpane with the foil sandwiched between the double panes so that the two panes have a common center, and Creates an equal amount of foil overhang on each pane edge. The annular area of ​​this larger pane can be used to provide a location for the weld seam. The stacked assemblies were joined together using the equipment and technique...

example 3

[0073] Example 3: Reference Figure 13 , forming a highly airtight seal around a rectangular neutron detector airtight container of 1 m x 1 m x 1 cm. The airtight container is used to fill the argon and induction device. The airtight container comprises two parallel panes 1, 2, a seal and a glass edge spacer 41. An uncoated transparent soda-lime pane of 1 m x 1 m is used for pane 1, while an uncoated soda-lime pane of 0.975 m x 0.975 m is used. Coated transparent soda-lime glazing is used for window pane 2. Four glass edge spacers 41 (e.g., 0.965 meters long and having a 1 cm x 1 cm cross-section) are rigidly and hermetically bonded to the window pane 2 with solder glass 42, each spacer adjacent to one of the window panes 2. edge. Similarly, the corner joints between the four glass spacers 42 are filled with solder glass to form a highly hermetic seal when heated to 450°C.

[0074] After cooling, the excess solder glass weld path on the corner joints that protrudes intenti...

Abstract

A hermetically sealed closed container comprises at least two substantially identically shaped wall elements, and a spacer system forming an interior space between said wall elements. The container also includes a bridging element having one or more layers of flexible metal foil extending between adjacent, respective edges of the wall elements to separate the interior space from the The surroundings are spaced out. The overall thickness of the bridging element has substantially no step discontinuities along the intended weld path; and the bridging element is ultrasonically welded to each wall element to form a continuous line of joint.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 935,250, filed February 3, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a flat glass assembly or glazing unit and, more particularly, to a flat glass assembly comprising a flexible sealing system and a method for its manufacture. Background technique [0004] Hermetically sealing a flat closed container made of window glass eliminates the migration of harmful gases into or out of the closed container. Large flat hermetically sealed glass containment containers as anti-fog multilayer argon-filled insulating glass assemblies for windows, vacuum insulating glass units, flat panel displays and neutron detector panels for detecting nuclear materials . [0005] Many existing insulating glass units (eg, vacuum insulating glass units or glass assemblies) comprise t...
