International Classification:

B05B 706

US Classification:

239424, 239423, 239422, 239428, 239432

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 miniaturized, the spray gun is capable of flowing coating mixture at the same rate as the larger version convergent spray gun.

International Classification:

B05B007/06

US Classification:

239423000

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 first fluid and atomizing air. The other fluid nozzle for flowing another fluid 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 miniaturized, the spray gun is capable of flowing coating mixture at the same rate as the larger version convergent spray gun.

Appl. No.:

8/310900

Inventors:

Terry L. Hall - Huntsville AL
Jack G. Scarpa - Huntsville AL
David D. Mathias - Athens AL

Assignee:

USBI Co. - Huntsville AL

International Classification:

B05B 714
B05B 716

US Classification:

239 9

Abstract:

Coating a substrate with a reinforced resin matrix comprised of liquid resin and reinforcing material can be accomplished with an apparatus where the liquid resin and the reinforcing material are mixed external to the apparatus prior to impacting the substrate. The liquid resin is directed through a cylinder 12 and then through an orifice 7 in nozzle 1, while the reinforcing material is carried in a gas stream through cavity 13, around cylinder 12, and past the nozzle 1. As the reinforcing material passes the nozzle 1, it is drawn into the liquid resin. Due to the distribution of the reinforcing material around the liquid resin flow, the reinforcing material is substantially homogeneously wetted by the liquid resin prior to impacting the substrate.

Appl. No.:

8/995429

Inventors:

Jack Scarpa - Huntsville AL
Terry Hall - Huntsville AL
David D. Mathias - Athens AL

Assignee:

USBI Co. - Cape Kennedy FL

International Classification:

B01F 1302

US Classification:

366101

Abstract:

A pair of concentric tubes having an inlet and an outlet with the outer tube being closed at either end and the inner tube having a plurality of holes with compound angles designed to impart a swirling motion of the air admitted into the interior of the inner mixing tube. The holes are judiciously located around the inner tube for creating a swirling pattern. The inlet of the tubes leads the dry particles of two different compositions intended to be mixed into the mixer and the outlet leads the mixture to the next station utilizing the mixture. Air admitted internally of the outer tube feed the plurality of holes and the force of the air can be controlled to control the transport of the mixed particles.

International Classification:

B05B 128

US Classification:

239290

Abstract:

A wand with a convergent spray end effector is utilized in a portable coating system for roofs, skid proof walk-ways and the like and includes a system of transporting the resin and dry filler materials to the end effector by including a movable cart that is capable of being raised that carries the pumps, meters, eductor and its dry powder feeder and optional pressure pots for the resin and including the necessary hoses to convey the materials to the wand. The wand includes the trigger and the necessary controls for effectuating the spray of the coating on the surface of the substrate.

US Classification:

Abstract:

Many industries such as construction and aerospace industries use high build coatings for various purposes. Spray system for applying high build coatings allow thick coating to be applied relatively quickly as opposed to manual methods. The present application provides for a spray system including a spray apparatus having a conveyance device which provides a motive force created by a vacuum for delivering a dry material to the nozzle of the apparatus, the conveyance device including an array of bores for separating the dry material to provide substantially uniform wetting of the dry material when the dry material enters the nozzle. The conveyance device is particularly useful in applying plaster and stucco. The present apparatus eliminates concerns of pot-life, waste and product uniformity by wetting the dry material close to the nozzle outlet.
