Abstract: A method for electrostatically applying a thermoplastic resin coating on a threaded portion of a fastener to provide a self locking element thereon. A plurality of fasteners are moved by a spaced pair of endless belts passed a spray station where a stream of powdered resin is directed toward the threaded ends of the fasteners. The fasteners and resin are polarized to opposite polarities at the spray station whereby the powdered resin is attracted to and clings to the threaded ends of the fastener and extends completely about the circumference of said ends. Air jet nozzles located downstream of the spray station may direct streams of compressed air against certain portions of the powdered resin to remove the resin therefrom to provide uncoated lead threads and to regulate the distance that the resin extends circumferentially about the threaded ends to provide a coating extending between 180 degrees and 360 degrees about the threaded ends. The powder coated fasteners then pass through a heating zone which melts the powdered resin on the threaded ends forming a permanent bond therebetween and providing the self locking element thereon. The fastener also may be heated before the stream of polarized powdered resin particles is directed toward the fastener to assist in bonding the resin to the fastener and to enable a greater buildup of thermoplastic resin to be applied thereto.

Abstract translation: 一种用于将热塑性树脂涂层静电施加在紧固件的螺纹部分上以在其上提供自锁元件的方法。 多个紧固件通过间隔开的一对通过喷雾站的环形带移动，其中粉末状树脂流指向紧固件的螺纹端。 紧固件和树脂在喷雾站处被极化为相反的极性，由此粉末状树脂被吸引并紧固到紧固件的螺纹端并且完全围绕所述端部的圆周延伸。 位于喷雾站下游的空气喷嘴可以将压缩空气流引导到粉末状树脂的某些部分以从其中除去树脂，以提供未涂覆的引线，并调节树脂围绕螺纹端部圆周延伸以提供涂层的距离 在螺纹端部延伸180度和360度之间。 然后，粉末涂覆的紧固件通过加热区，该加热区将螺纹端部上的粉末状树脂熔化，从而在其间形成永久粘合，并在其上提供自锁元件。 在将偏光粉末树脂颗粒流引向紧固件之前，紧固件也可以被加热，以有助于将树脂粘合到紧固件上，并且能够使更多的热塑性树脂积聚在其上。

Abstract: Disclosed is a novel method for applying a film of a coating composition in liquid form onto a substrate which applied film cures rapidly at room temperature without heat curing. The coating composition comprises a hydroxyl-functional compound (preferably bearing aromatic-hydroxyl groups) and a multi-isocyanate cross-linking agent, optionally dispersed in a fugitive organic solvent therefor. The method comprises the steps of:(a) concurrently generating an atomizate of said coating composition and a carrier gas bearing a catalytic amount of a vaporous tertiary amine;(b) mixing said atomizate and said vaporous catalytic amine-bearing carrier gas flow; and(c) directing said mixture of step (b) onto said substrate to form said applied film.

Abstract: Method and apparatus by which the interior of a pipe is coated with a uniform thickness of plastic. A source of heat-meltable plastic material in particular form is connected at a location upstream of the inlet end of the pipe, while the opposed end of the pipe is made attachable to a reduced pressure. A source of compressible fluid is also connected at a location upstream of the inlet end of the pipe. The pipe is preheated and then rotated axially while a charge of powdered plastic is forced through the pipe by the compressible fluid. The powdered plastic which flows through the pipe is a finite pocket of the finely divided plastic, which is smaller in volume respective to the volume of the pipe being coated.

Abstract: A nozzle assembly for an electrostatic powder spray gun is disclosed. The powder spray gun includes an electrically non-conductive barrel through which a high voltage electrical path passes. The nozzle assembly is mounted in the open forward end of the barrel and includes a sleeve located on the center axis of the barrel for directing a flow of a pressurized gas, e.g., air, through the center of the nozzle assembly, a nozzle surrounding the sleeve defining an annular flow path for powder spray coating material encircling the flow of pressurized air and an air deflector cap for directing the pressurized air radially outwardly and into the flow of powder spray coating material being emitted from the nozzle. The air impacts the powder coating material to form a conical spray pattern of coating material. The gun also includes an electrode extending out of the nozzle assembly for electrostatically charging the powder. The nozzle assembly eliminates mechanical powder deflectors and the problems attendant therewith.
