Abstract: A convergent type of spray gun is made portable by miniaturizing the components with the addition of a double tube, fluid tip and air cap for defining the discharge nozzle for the liquid resin and atomizing air. The dry powdered nozzle is likewise miniaturized and is adapted to fit over the double tube, fluid tip and air cap arrangement by including a sleeve disposed therebetween. The main body is configured in either an L-shape or straight-through configuration. Although the component parts are min is the spray gun is capable of flowing coating mixture at the same rate as the larger version convergent spray gun.

Abstract: A shut-off system that is semi-automatic or fully automatic shuts off the mechanism for flowing resin, air and filler to a miniaturized convergent spray gun so as to stop the flow of the ingredients of being sprayed and purging the spray gun so that the residue ingredients do not cure and destroy the gun.

Abstract: A convergent spray gun which combines a liquid resin and dry metallic powder externally of the nozzle of the spray gun that utilizes a pair of diametrically opposing passages disposed at 0.degree. and 90.degree. relative to the central resin discharging orifice where the central orifice is approximately 0.015 inch and the air for atomizing the fluids is approximately 0.187 inch and the atomizing angle is approximately 180.degree.. The metallic filler is added to the plume of the convergent spray at the low pressure section and the ratio of the fluids are controlled by a computerized system. The spray gun, controls and mixing chambers of the resin (two part) and powder fillers are housed in separate rooms and the dust where the powder fillers are metered is controlled.
