  • Window glass with an electroconductive layer, obtained by pyrolysis of powdered components, which can be used as a windshield for an automobile
    Patent number: 5786289
    Abstract: A window glass comprising at least one sheet of glass coated with an electroconductive ITO layer, pyrolyzed from powdered components, combined with a flexible plastic material of the PVB, PU, PVC type, with an index approaching more the index of the ITO layer than the index of air, with which the said layer is coated, and a sheet of glass dyed in the mass, with the same color as the ITO layer, and with properties of reduced energy transmission also entering advantageously into the composition of the window glass is provided. The invention particularly applies to the production of heated windshields for automobiles.

  • Laminated glass with an electroconductive layer
    Patent number: 5324374
    Abstract: A laminated glazing is prepared by a providing an electroconductive layer on side 3, the sides of such a glazing being conventionally numbered from 1-4 starting from the outside of the glazing when mounted on a vehicle, towards the inside. The electroconductive layer is formed by powder deposition and pyrolysis to form a ITO layer on a glass pane, which is subsequently bent such that the surface bearing the ITO layer is convex. This glass is laminated with a glass of the same curvature, between which panes is sandwiched a plastic interlayer. On the side of the interlayer facing the electroconductive layer, current lead strips, in the form of metal tinsel, are provided, such that upon lamination, the metal lead strips are in electrical contact with the electroconductive layer and lead to a source of electricity. The resulting window is produced more simply, more reliably, and exhibits improved defogging.
