Abstract
Abstract The method of making the panel includes the steps of flooding one of the panes with the spherical members and a liquid. The liquid is evaporated. Positioning another pane on top of the spherical supporting elements and followed by drawing a vacuum on the space between the dual pane window structure and joining the edges of the panes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A method of making a multi-pane window structure comprising: applying a mixture of a liquid and spherical spacing members to a substantially horizontally disposed first glass pane to randomly dispose the spacing members on the pane and to temporarily locate the spacing members on the pane; evaporating the liquid from the pane and spacing members; positioning a second glass pane on top of the first pane, the spacing members being located there between; drawing a vacuum on the space between the panes to bow the panes sufficient to fixedly located the spacing members there between in the absence of fusing or adhesively bonding the spacing members to either pane; and joining the panes to permanently seal the evacuated space.
Claim 2
Independent Claim
119 words
A method of making a multi-pane window structure comprising: applying a mixture of a liquid and spherical spacing members to a substantially horizontally disposed first glass pane to randomly dispose the spacing members on the pane and to temporarily locate the spacing members on the pane; evaporating the liquid from the pane and spacing members; positioning a second glass pane on top of the first pane, the spacing members being located there between; drawing a vacuum on the space between the panes to bow the panes sufficient to fixedly located the spacing members there between in the absence of fusing or adhesively bonding the spacing members to either pane; and joining the panes to permanently seal the evacuated space.
Claim 3
Dependent Claim
11 words
The method of claim 1 wherein said liquid is distilled water.
Claim 4
Dependent Claim
19 words
The method of claim 2 wherein the spherical members are selected from the group consisting of glass and polystyrene.
Claim 5
Dependent Claim
31 words
The method of claim 1 further comprising positioning fusible elements along the edge portions of the panes and wherein the panes are joined by fusing the panes to the fusable elements.
Claim 6
Dependent Claim
15 words
The method of claim 4 wherein the fusible elements are leaded glass filaments or ribbons.
