Claim 1
Independent Claim
65 words
A method of improving the conductivity of a laminate of resinous insulating material having dispersed therein metallic articles selected from the group consisting of metal-coated glass fibers, strips of aluminum foil, wire and flakes comprising the step of passing electrical energy through the laminate of sufficient strength to break down the dielectric resistance of the insulating material at points of contact of the metallic articles.
Claim 2
Independent Claim
65 words
A method of improving the conductivity of a laminate of resinous insulating material having dispersed therein metallic articles selected from the group consisting of metal-coated glass fibers, strips of aluminum foil, wire and flakes comprising the step of passing electrical energy through the laminate of sufficient strength to break down the dielectric resistance of the insulating material at points of contact of the metallic articles.
Claim 3
Independent Claim
61 words
A method of improving the conductivity of a laminate of resinous insulating material having dispersed therein metallic articles selected from the group consisting of metal-coated glass fibers, strips of aluminum foil, wire and flakes comprising the step of passing electrical energy through the laminate of sufficient strength to permanently enhance the electrical connection at points of contact of the metallic articles.
Claim 4
Independent Claim
61 words
A method of improving the conductivity of a laminate of resinous insulating material having dispersed therein metallic articles selected from the group consisting of metal-coated glass fibers, strips of aluminum foil, wire and flakes comprising the step of passing electrical energy through the laminate of sufficient strength to permanently enhance the electrical connection at points of contact of the metallic articles.
