ELECTRICALLY HEATED, GLASS VISION UNIT |
摘要 |
<p>This specification teaches an electrically heated, glass vision unit having a complex curved configuration. The unit is made by cutting a glass substrate (10) from a flat glass bracket (12). The glass substrate (10) has first and second surfaces separated by a uniform distance. A pair of electrically conductive bus bars (16-16) are applied to one of the surfaces of the glass substrate (10). The bus bars (16-16) are so positioned on the flat glass substrate (10) that when the substrate (10) is bent to form the glass vision unit of complex curved configuration, inboard edges (16a-16a) of the pair of electrically conductive bus bars (16-16) are equally distant from one another throughout their entire extent. The flat glass substrate (10) is bent to form the glass vision unit of complex curved configuration. A conducglass substrate (10) and extends between the pair of bus manner, when electrical energy is applied to the bus bars (16-16), a uniform flow of current takes place from one bus bar to another bus bar so that a uniformly developed heating pattern is established between the bus bars (16-16).</p> |
