Abstract
Abstract The invention is in a glass pane including a conductive strip around or substantially around its marginal edge. The conductive strip when included in circuit to a source of power may be heated for treating a strand of adhesive comprising an adhering medium between the glass pane and a frame thereby to enable both installation of the glass pane in the frame and permit removal of the glass pane from the frame with relative ease.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
88 words
A process for attaching a glass pane to a frame which comprises the steps of: (a) depositing a conductive material in strip form on the marginal edge of said glass pane; (b) attaching the conductive material onto the glass; (c) depositing a layer of thermoplastic adhesive between the glass pane and the frame; (d) connecting a source of electric power to the conductive strip; and (e) passing electric current through the conductive strip to heat the adhesive to its deformation temperature to bond the glass to the frame.
Claim 2
Dependent Claim
88 words
A process for attaching a glass pane to a frame which comprises the steps of: (a) depositing a conductive material in strip form on the marginal edge of said glass pane; (b) attaching the conductive material onto the glass; (c) depositing a layer of thermoplastic adhesive between the glass pane and the frame; (d) connecting a source of electric power to the conductive strip; and (e) passing electric current through the conductive strip to heat the adhesive to its deformation temperature to bond the glass to the frame.
Claim 3
Dependent Claim
28 words
The process as in claim 1, characterized in that the conductive strip is connected as an electric resistance heater and is heated by the direct passage of current.
Claim 4
Dependent Claim
42 words
The process as in claim 1, characterized in that the conductive strip disposed along the edge of the glass pane provides a closed circuit, and the conductive strip is connected at at least two points providing substantially equal length paths for current.
Claim 5
Dependent Claim
52 words
The process according to claim 1, wherein the heat is generated by attaching one side of a source of high frequency electricity to the conductive strip and the other side of the source of high frequency electricity to the frame, whereby the plasticization of the adhesive layer is accomplished by dioelectric heating.
Claim 6
Dependent Claim
25 words
The glass pane as in claim 4, characterized in that the conductive strip includes current connecting pieces in the form of flexible connecting litz wires.
Claim 7
Dependent Claim
42 words
The glass pane as in claim 5, characterized in that the conductive strip comprises a closed circuit and whereby the connecting litz wires are disposed on two opposite marginal edges thereby to subdivide the conductive strip into two substantially equal length sections.
Claim 8
Dependent Claim
37 words
The glass pane as in claim 5, characterized in that the conductive strip comprises an interrupted circuit and whereby the connecting litz wires are disposed at the ends of the circuit at either side of the interruption.
Claim 9
Dependent Claim
34 words
The glass pane as in claim 5 characterized in that the conductive strip consists of a metal foil band and including an adhesive layer for connection of the metal foil to the glass pane.
Claim 10
Dependent Claim
35 words
The glass pane as in claim 6 characterized in that the conductive strip consists of a flexible litz wire and including an adhesive layer for connection of the flexible litz wire to the glass pane.
Claim 11
Dependent Claim
17 words
The glass pane as in claim 5 characterized in that the conductive strip comprises a metal layer.
Claim 12
Dependent Claim
19 words
The glass pane as in claim 12 characterized in that the adhesive strand is disposed on the conductive strip.
