摘要： The present invention is directed to a process for the application of fluoropolymer to a preselected area of a threaded fastener, and particularly to substantially all of the threads of the fastener. The fluoropolymer is supplied to a spray nozzle (10) in powder form and is subjected to a triboelectrostatic charging process so that individual particles discharged from the spray nozzle are electrically charged. In the preferred form of the invention, the fluoropolymer powder is triboelectrically charged, entrained in an air stream discharged from the nozzle and directed onto the preselected area of the fastener. In this manner a generally uniform powder coating is deposited onto the preselected area of the fastener while the fastener is maintained at room temperature. Thereafter, the fastener is heated to a temperature above the melting point of the fluoropolymer to thereby coalesce the deposited powder into a continuous film coating which adheres, upon cooling, to the pre-selected area of the fastener. In accordance with a preferred embodiment, the fastener is heated in a manner which raises the temperature of only the preselected area of the fastener to the fluoropolymer melting point. This preferred heating technique minimizes the retention of fluoropolymer inadvertently deposited on areas of the fastener other than the preselected area, and allows this undesired fluoropolymer to be easily removed, even after heating.

摘要： A continuous-flow powder feeding device for use in applying powder to threaded articles. A by-pass line (25) permits powder to constantly circulate through a powder supply line (35). In response to a signal that a threaded article is in a position for powder to be applied, the powder supply line is automatically moved out of communication with the by-pass line (25), and into communication with a powder application line (35).

摘要： A method for fabricating a threaded fastener having a discontinuous coating of a contaminant-inhibiting coating material. In a preferred embodiment, the threaded fastener is formed so as to provide a coated fastener with substantially coating-free crests. The article resulting from the fabrication method also forms a part of the present invention. The resulting threaded fasteners include electrically conductive portions, allowing use of the fasteners in fabricating structural assemblies using welding techniques.

摘要： The present invention is directed to an internally threaded prevailing-torque type selflocking fastener which employs a patch (20) of fused thermoplastic material as the locking element and which satisfies the functional torque requirements of both IFI 100/107 (1987) and IFI 101 (1987). In accordance with the present invention the fastener comprises a metal body (10) having a bore (12) extending to its opposing ends (14,16), the bore having a threaded surface (18), a patch (20) of polymeric material applied and fused to a portion of the threaded surface (18), and the fastener meeting the prevailing-torque characteristics specified in both IFI 100/107 (1987) and IFI 101 (1987). The invention is also directed to a process wherein an internally threaded fastener is processed by first applying and fusing a polymeric resin material to at least a portion of the fastener's threaded surface (18) and thereafter conditioning the frictional properties of the fastener such that its prevailing-torque performance characteristics meet both IFI 100/107 (1987) and IFI 101 (1987).

摘要： An improved apparatus for generating a powder stream to be applied to a work piece (22) includes a powder reservoir (12), a mixing chamber (14), a powder metering valve (36,38), a transfer conduit (16), and a nozzle (18). The metering valve allows control of the powder flow from the reservoir into the mixing chamber where it is dispersed with and entrained in an air flow entering the chamber through an aspirating inlet (30). The air entrained powder is then conveyed from the mixing chamber via the transfer conduit to the nozzle. The nozzle includes a controllable gas flow input (43) and a powder stream generating passageway (42) configured and associated with the transfer conduit to generate a reduced pressure in the conduit and mixing chamber which draws the air borne powder from the chamber into the nozzle. One or more of the individual components are adjustable to control the size, configuration, thickness or other parameters of the coating on the work piece as a result of the applied powder stream.
