Abstract
Abstract An adhesive copper strip is provided with an opaque covering on the adhesive side thereof. The opaque covering may be provided in one of two ways. In one embodiment, a coating of black acrylic or epoxy is applied to the copper strip beneath the adhesive layer. In a second embodiment, the adhesive contains carbon particles dispersed uniformly throughout the adhesive in sufficient quantity to render the adhesive opaque.

Claim 1
Independent Claim
220 words
A composite formed of interconnected sections of glass comprising: a first section of glass having a first edge and opposed front and back surfaces; a second section of glass having a second edge and opposed front and back surfaces, said second edge of said second section being in confronting, closely spaced relation with said first edge of said first section; a first strip of copper foil adhesively secured on a back side thereof to said first edge of said first section and to adjacent portions of said front and back surfaces of said first section; a second strip of copper foil adhesively secured on a back side thereof to said second edge of said second section and to adjacent portions of said front and back surfaces of said second section, each of said first and said second strips of copper foil comprising a layer a copper, a layer of a pressure sensitive adhesive disposed on a back side of said layer of copper, and opaque means covering said back side of said layer of copper, said opaque means comprising a quantity of black particles dispersed uniformly throughout said adhesive layer and preventing said back side of said layer of copper from being visible; and a bead of solder for securing together said first and said second strips of copper foil.
