Abstract
Abstract A double-pane window containing a dry atmosphere is produced by placing two panes of transparent material in a spaced-apart relationship; a sealing means is placed about the periphery of the adjacent faces of the panes of transparent material to enclose a sealed area which is then evacuated and filled with a dry gas. The window is then mounted in a suitable frame to maintain the panes of transparent material in a suitable spaced apart relationship.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
154 words
A double-pane window having a dry atmosphere comprising: a first pane of transparent material; a second pane of transparent material essentially parallel with the first pane; a strip of flexible adhesive material disposed along the periphery of the adjacent sides of the panes of transparent material in sealing engagement with the panes enclosing a sealed area between the panes; a dry gas within the sealed area between the panes; a plurality of rigid spacers each having a stem portion inserted in the flexible adhesive material and having a head portion larger than the stem portion, which head portion is in contact with both panes of transparent material and maintains the panes of transparent material in spaced apart relationship; and framing means along the edges and the periphery of the outer sides of the panes of transparent material for holding the panes stationary relative to one another and in contact with the flexible adhesive material.
Claim 2
Dependent Claim
154 words
A double-pane window having a dry atmosphere comprising: a first pane of transparent material; a second pane of transparent material essentially parallel with the first pane; a strip of flexible adhesive material disposed along the periphery of the adjacent sides of the panes of transparent material in sealing engagement with the panes enclosing a sealed area between the panes; a dry gas within the sealed area between the panes; a plurality of rigid spacers each having a stem portion inserted in the flexible adhesive material and having a head portion larger than the stem portion, which head portion is in contact with both panes of transparent material and maintains the panes of transparent material in spaced apart relationship; and framing means along the edges and the periphery of the outer sides of the panes of transparent material for holding the panes stationary relative to one another and in contact with the flexible adhesive material.
Claim 3
Dependent Claim
27 words
The window of claim 1 in which each spacer has a cylindrical head portion, the diameter of which determines the spacing between the panes of transparent material.
Claim 4
Dependent Claim
29 words
The window of claim 1 in which the framing means includes flexible beading and a rigid frame maintaining the beading in sealing engagement with the panes of transparent material.
Claim 5
Dependent Claim
111 words
The window of claim 3 in which the flexible beading has a first wall disposed around the edges of the panes of transparent material, a second wall, attached at an end to a first end of the first wall, disposed about the periphery of the outer side of the first pane of transparent material, and a third wall, attached at an end to the second end of the first wall, disposed about the periphery of the outer side of the second pane, the second and third walls each including a first and second flange extending outwardly from the wall and a sealing ledge pivoted on the free end of the wall.
Claim 6
Dependent Claim
121 words
The window of claim 4 in which the frame has a first wall positioned over the first wall of the beading, a second wall engaging the flanges of the second wall of the beading and contacting one end of the sealing ledge at the end of the second wall and maintaining the opposite end of the sealing ledge engagement with the first pane of transparent material, and a third wall in sealing engagement with the flanges of the third wall of the sealing bead and bearing against the end of the sealing ledge on the end of the third wall of the sealing bead maintaining the opposite end of the sealing ledge in engagement with the second pane of transparent material.
Claim 7
Dependent Claim
28 words
The window of claim 5 in which the first wall of the frame includes a flanged extension essentially parallel to and away from the panes of transparent material.
Claim 8
Dependent Claim
14 words
The window of claim 6 in which the dry gas is dry nitrogen gas.
Claim 9
Dependent Claim
27 words
The window of claim 7 in which each spacer has a cylindrical head portion, the diameter of which determines the spacing between the panes of transparent material.
