Abstract: Method and device for providing a layer (6) of a coating material on the inner side (2) of a display window (1) for a color display tube. A drop (3) of a suspension of said coating material is deposited on the inner side of the display window, its axis of symmetry (4) being oriented vertically. Then the display window is rotated around said axis of symmetry, and at the same time, said axis is tilted to a horizontal position.

Abstract: A coating fluid for forming a phosphor screen is coated on an inside surface of a glass panel having a wall portion provided with a wall portion edge at an outside surface of the glass panel. Then, the coating fluid on the inside surface of the glass panel is dried after facing the inside surface of the glass panel downward and placing the wall portion edge onto a panel support stand in a manner that the panel is supported on the support stand primarily by the wall portion edge. Since the glass panel is placed on the support stand in a manner that only the edge portion contacts the support stand, the scattering of coating fluid during this placement can be prevented. As a result, a uniform phosphor layer can be formed on the inside surface of the panel without decreasing the productivity for making such a glass panel on which a phosphor layer is formed.

Abstract: A tank construction including an outer shell of steel material comprised of two half members welded together. The half members are formed by a deep drawing process. An inner shell of non-corrosive material is cast inside the outer shell by a rotational casting procedure with the external surface of the inner shell located adjacent the internal surface of the outer shell. The inner shell of non-corrosive material provides a substantially leak-fight liner for the outer shell to thus prevent contact between the contents of the tank and the outer shell. The rotational casting of the inner shell inside the outer shell is accomplished by charging the outer shell with a non-corrosive material and then subjecting the outer shell to a rotational casting movement while heat is applied to the outer shell. The outer shell serves as a mold for the inner shell wherein the mold (outer shell) becomes a permanent part of the completed tank.

The method is useable for applying a liquid vitreous enamel coating material to a water heater tank, to be subsequently dried and furnace heated to form a glazed enamel internal coating.

Pressure from pump(76) is transmitted to the tank(10 by the liquid coating material and held for a prescribed time interval to prove tank integrity. The method avoids excessive shear, hence viscosity changes in thixotropic coating materials.
