Abstract
Abstract A repair method for repairing electrical interconnect between an electrical bus bar and an electrically conductive ply of a heatable laminate. The method uses the steps of filling a syringe with an electrically conductive material, inserting the needle of the syringe into the laminate parallel to the conductive ply and along the surface thereof until the needle reaches the interconnect and then operating the syringe to inject an amount of the material into an area about the conductive ply.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
103 words
A repair method for repairing electrical interconnect between electrical buss bars and electrically conductive ply of a heatable laminate, comprising the steps of: filling a syringe with an electrically conductive material, the syringe including a hypodermic needle affixed thereto; inserting the needle into the laminate parallel to the conductive ply and along the surface thereof in alignment with the buss bar until the needle reaches the interconnect such that the needle moves over the buss bar to the area proximate the interconnect; operating the syringe to inject an amount of the material into an area about the conductive ply; and withdrawing the needle.
Claim 2
Dependent Claim
103 words
A repair method for repairing electrical interconnect between electrical buss bars and electrically conductive ply of a heatable laminate, comprising the steps of: filling a syringe with an electrically conductive material, the syringe including a hypodermic needle affixed thereto; inserting the needle into the laminate parallel to the conductive ply and along the surface thereof in alignment with the buss bar until the needle reaches the interconnect such that the needle moves over the buss bar to the area proximate the interconnect; operating the syringe to inject an amount of the material into an area about the conductive ply; and withdrawing the needle.
Claim 3
Dependent Claim
29 words
The method as set forth in claim 1, wherein the step of inserting, operating and withdrawing the needle and syringe is repeated along the length of the buss bar.
Claim 4
Dependent Claim
37 words
The method as set forth in claim 2, further including the step of applying a heat sensitive material to a surface of the laminate and then applying electrical power to the bass bar to heat the laminate.
Claim 5
Dependent Claim
40 words
The method as set forth in claim 3, further including the step of using the heat sensitive material as a guide to determine the amount of material to be injected into the laminate along the length of the bass bar.
