Title: Coated glass articles
IPC: C03C17/25
Filed: 1956-05-18
Abstract: A window closure comprises a curved sheet of glass having a metal oxide coating of varying thickness on a surface thereof, said coating effecting heat and light absorption, characterized by the fact that the metal oxide coating covers only a portion of the glass sheet, the remainder of the sheet being substantially clear, and that the thickness of the coating increases progressively outwards from the clear portion. The sheet may be curved both longitudinally and transversely, so as to make a car windscreen with side wings and a roof portion, and the coating may be thickest in the roof portion. The window closure may be prepared by heating a flat sheet of glass, allowing it to sag into the shape of a mould, then spraying the heated glass with a solution of the chloride of tin, antimony, bismuth, iron, titanium or mixtures thereof in water, hydrochloric acid or methanol. The variation in thickness of the coating may be achieved by the use of spray nozzles producing sprays of "tear-drop" or "dumb-bell" shape, and also by altering the angle of the spray with respect to the sheet, and the speed of passage of the sheet past the spray. More than one coating may be applied, and the sheet may be reversed end for end between applications so as to avoid any variation in thickness between the leading edge and the trailing edge.
