Abstract: Washing and release agent application mechanisms, including a structure defining a chamber into which a magazine of loaf molds may be driven for treating the surface of the molds, wherein the structure includes doors opening for permitting the ingress and egress of a magazine in the chamber and the mechanism includes fluid distributing nozzles on wands for entry within the molds and treating the interior surfaces thereof. The mold washing mechanism also includes a U-shaped header which traverses the outsides of the molds for washing the outside surfaces.

Abstract: The powder used in applying a light diffusing coating to the inner wall of an incandescent lamp bulb is deposited substantially free of clumps by, amongst other things, maintaining the powder in suspension in a closed container prior to deposition. The powder in said container is also maintained at a constant level. The powder is carried from the container to the lamp bulbs by a stream of air and is passed through a vortex nozzle which breaks up clumps or agglomerates of powder.

Abstract: A mobile gunning apparatus is disclosed that is particularly adapted for applying refractory material to the interior of coke ovens, or the like. The apparatus is arranged for mounting on a wheeled vehicle and includes an extendable boom carrying the gunning nozzle and structure enabling the boom and nozzle to be universally movable with respect to the vehicle.

Abstract: An improved system for washing and coating metal can bodies, such as seamless aluminum and tin plate can bodies, in a can processing line wherein various can washing, coating and curing stations are arranged in a unique fashion along the line so as to utilize generally fully compatible washing and coating materials, the residues of which are adapted to be either recycled or discharged into a common waste disposal system, as well as an improved coated can body.

Abstract: A method of and an apparatus for the internal coating of ducts with a synthetic resin, especially long steel pipes or tubes, in which gas-entrained synthetic-resin particles are passed through the tube while the latter is heated progressively by displacing the tube relative to a surrounding induction-heating coil. Thereafter, a gas stream free from particles is used to clear the interior of the tube.
