1 Claim.
This invention relates to a heating element embodying a glass plate having deposited thereon a conducting metal grid in which the several bars of the grid are so proportioned that the ends thereof adjacent to one edge of the plate are 01 higher resistance per unit length than those ad- J'acent to the opposite edge, so that the generation of heat by the grid is asymmetrical.
The accompanying drawings, in which corresponding marks are designated by corresponding marks of reference, .is a plan view of a glass panel, or plate, having a conducting grid deposited thereon in accordance with this invention.
The plate, or panel, A has deposited thereon a conducting grid B or metal which may be deposited electrically, chemically, or, as is preferred, by a thermal gun. Each bar of the grid is each connected at one end to the corresponding end 01' an adjacent bar, and one end of each of the external bars is connected when in use to one end or an electric teed circuit. To provide for I the asymmetrical heating before referred to, we
so construct the bars that each of them has greater resistance per unit length on one side or the medial line of the panel, or sheet, than on the other. In the instant case this is accomplished by making the breadth of the bars greater at the bottom of the sheet than at the top.
As the space between the several bars is of uniform width from end to end, this results in on the other.
