Patent number: 6892963Abstract: 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.Type: GrantFiled: September 10, 1999Date of Patent: May 17, 2005Assignee: Usbi CoInventors: Jack G.

Patent number: 6074085Abstract: 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.Type: GrantFiled: December 20, 1997Date of Patent: June 13, 2000Assignee: USBI Co.Inventors: Jack Scarpa, Terry Hall, David D.

Patent number: 5579998Abstract: 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.Type: GrantFiled: September 22, 1994Date of Patent: December 3, 1996Assignee: USBI Co.Inventors: Terry L. Hall, Jack G. Scarpa, David D. Mathias

Patent number: 5565241Abstract: A convergent end-effector which combines a liquid and dry flow external to a spray nozzle eliminates clogging problems common in the prior art spray coating systems. The end-effector utilizes a nozzle with an orifice and at least one atomizing hole, a conduit for directing a liquid resin through the nozzle and an outer housing disposed around said conduit to form a cavity. Reinforcing material enters the cavity on an gas stream supplied and controlled by an eductor located prior to the outer housing, in the direction of the nozzle, and at an angle of less than about 90.degree. with respect to the conduit. The end of the conduit near the nozzle is preferably angled toward the nozzle to further direct the reinforcing material into the liquid resin.Type: GrantFiled: August 10, 1994Date of Patent: October 15, 1996Assignee: USBI Co.Inventors: David D.

Patent number: 4917298Abstract: A method of spraying fiber-containing fluids that results in smoother, more uniform coatings. The method comprises displacing a fiber-containing fluid through a nozzle assembly at about 69 KPa to about 386 KPa. The fibers have a length of about 1 mm to about 6 mm. The nozzle assembly comprises a nozzle extension, an elbow joint, and a nozzle in series communication through at least two hollow fluid passages. A first fluid passage exits at a first nozzle outlet having a diameter of about 2.5 mm to about 3.5 mm. A second gas passage exits at a second nozzle outlet and directs a gas at the fiber-containing fluid to atomize the fluid. Control means are disposed upstream of the nozzle assembly for controlling the fiber-containing fluid flow and the gas flow.Type: GrantFiled: December 5, 1988Date of Patent: April 17, 1990Assignee: USBI CompanyInventor: David N.

Patent number: 4877638Abstract: A method of detecting cracks on the surface of an article after removal of a coating. A U.V. detectable compound is incorporated in a thermoset or thermoplastic grit blast media. A coated article is grit blasted to remove the coating. The surface of the article is exposed to U.V. radiation to detect grit blast media trapped in surface cracks. This facilitates the detection of surface cracks. U.V. detectable grit blast media is also used to provide improved coating adhesion. A U.V. detectable compound is incorporated into an abrasive mixture. A flow of the abrasive mixture is directed at the article to remove material from the surface of the article. The surface of the article is exposed to U.V. radiation in order to detect residual abrasive mixture on the surface of the article. Substantially all the abrasive mixture detected by exposure to U.V. radiation is removed from the surface of the article and at least a portion of the surface of the article is coated.Type: GrantFiled: June 13, 1988Date of Patent: October 31, 1989Assignee: USBI CompanyInventors: Howard L.
