1,246,749. Titania coating ASAHI GLASS CO. Ltd. 20 Aug., 1969 [22 Aug., 1968], No. 41438/68. Heading C1N. [Also in Divisions B1-B2] A method of coating a glass surface e.g. of sheet 1 evenly with a heat-reflecting film of titanium dioxide comprises disposing a rodshaped coating element 2 at a short distance from and parallel to said surface, feeding a solution of tetrabutyl titanate and ethyl silicate e.g. by pipe 9 between the coating element and the glass surface in the form of a meniscus 3 and inducing relative movement between the glass surface and the coating element to cause the meniscus to scan the glass surface, said relative movement being substantially parallel to the glass surface, thereby producing a film 4 and baking the film. A mensicus is defined as being a crescent-shaped surface of a liquid.
