Abstract

Abstract An electrical heating wire assembly for incorporation in a wired laminated glass panel, comprising an array of closely spaced parallel electric heating wires sandwiched between two sheets of films which are not adhesive to the cement to be used for bonding a pair of glass sheets forming said laminated glass panel one and at least one of the firms of which has said cement coated on the inside face thereof to secure the individual electrical heating wires in positions integrally therewith, said electrical heating wire assembly being used in such a manner that after removing the two sheets of films, the array of electrical heating wires carried by the cement layer is positioned on the inside face of one of said pair of glass sheet and the other one of the glass sheets is positioned on said array of electrical heating wires with the same cement interposed therebetween, whereby the two glass sheets are bonded together with the array of heating wires incorporated therein.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 161 words
A heating wire assembly for incorporation in a laminated glass panel, said assembly comprising an array of electrical heating wires to be connected between a pair of spaced electrical terminal means and arranged in suitably spaced parallel relationship and a thin layer of transparent, electrically insulative cement material disposed at least on one side of said array of electrical heating wires integrally therewith for securely fixing said array of electrical heating wires in position, said thin layer being thin relative to the diameter of said heating wires said thin layer of cement being constituted of substantially the same cement material as that to be used for laminating a pair of glass sheets forming the laminated glass panel, said thin layer of cement being disposed on at least one of the confronting faces of a pair of films which are not permanently adhesive to said cement material and between which said heating wire assembly is sandwiched, said cement material being polyvinyl butyral.
Claim 2
Dependent Claim 161 words
A heating wire assembly for incorporation in a laminated glass panel, said assembly comprising an array of electrical heating wires to be connected between a pair of spaced electrical terminal means and arranged in suitably spaced parallel relationship and a thin layer of transparent, electrically insulative cement material disposed at least on one side of said array of electrical heating wires integrally therewith for securely fixing said array of electrical heating wires in position, said thin layer being thin relative to the diameter of said heating wires said thin layer of cement being constituted of substantially the same cement material as that to be used for laminating a pair of glass sheets forming the laminated glass panel, said thin layer of cement being disposed on at least one of the confronting faces of a pair of films which are not permanently adhesive to said cement material and between which said heating wire assembly is sandwiched, said cement material being polyvinyl butyral.
Claim 3
Dependent Claim 18 words
A heating wire assembly as defined in claim 1, in which said pair of films are polyethylene films.
Claim 4
Dependent Claim 21 words
