METHOD FOR RESISTING GALLING

Thread lock

The method of making self-activating thread lock structures which comprises depositing a fluid material including an uncured fluid resin e.g. of microencapsulated material in the thread grooves of a threaded member; immediately thereafter, while the material is still in fluid condition, applying a thin fluid film- forming cover coat over the fluid material; and immediately thereafter transforming the cover coat into a thin, solid, dry, non-tacky, rupturable film by brief exposure to radiation, such as ultra-violet radiation. As previously noted excellent results have been obtained using ultra- violet lamps as the source of radiation to effect substantially immediate cure of the film-forming material, but other sources are comtemplated, such as electron beam radiation. Preferred film-formers are derived from acrylated urethane and glycidyl ether monomers, di- and tri- acrylate monomers, vinyl pyrrolidone, vinyl versatate and vinyl acetate.

Screws and nails for use in the woodworking industry

Elements with low friction coverings are produced by covering the element with a suspension containing (a) polytetrafluoroethylene, and (b) a thermoplast with a low m.p., and then baking the covered element at 140-330 deg.C. The method is used particularly for fastening elements used by the woodworking industry, such as screws and nails. the covered screws/nails penetrate materials such as wood and chipboard much more easily, owing to the low frictional resistance offered by the covering. The combination of the polytetrafluoroethylene and the themoflast to low m.p. is more effective in reducing resistance to penetration than polytetrafluoroethylene alone.

This application claims benefit of and priority to UK Patent Application No. GB1420508.2 filed Nov. 18, 2014.This invention relates to apparatus for masking a nut plate during painting of an aircraft part containing the nut plate.Various parts of aircraft, for example parts of aircraft wings and bodies are secured together by devices known as nut plates. Usually the parts are secured together by a large number of the nut plates which are located around the periphery of parts to be secured together. Often there is a slight misalignment between a hole in a first part and a hole in a second part which is placed on top of the first part. To allow for this misalignment, the nut plates take the form of a T-nut having a part located in a channel. A clip which is like a circlip is located in a groove in the channel, and grips the part of the T-nut in the channel. The T-nut moves within the clip, and thus the T-nut is able to move back and forth in the channel as may be required to compensate for the misalignment. When the aircraft parts are painted, for example sprayed, paint tends to get on the nut plate and secure it in position. It is then necessary to break the nut plate free from the dried paint so that the nut plate ...

Method and apparatus for coating internal cavities of objects with fluid

The present invention discloses an apparatus and process for coating hollow objects at precise bands within the internal cavity of the object. The process utilizes centrifugal force to apply the fluid to the object. A probe is moved from underneath the object thereby utilizing gravitational forces to prevent spillage of the material from the probe. A computer controls the pumping rate, the vertical movement of the probe and the rotational speed of the probe to allow the machine to precisely coat a band on the internal cavity of an article. The computer controlled operation eliminates the necessity to waste material. One application of the invention is in the coating of the threads of nuts with Teflon.

Topcoated phosphated bolts, nuts and washers

A bolt, nut and washer is first coated with an under-coating consisting of metal phosphate, and is then coated with a second or top coating consisting of a chromium compound and one or more of a metal salt of higher fatty acid, polyolefin and polyethylene tetrafluoride dissolved or dispersed in a vehicle. The composite coating improves the corrosion resisting and lubricating properties of bolts, nuts and washers coated therewith, and also serves as an excellent base for paints.

Surface pre-treatment method for pre-coated precipitation-hardenable stainless-steel ferrous-alloy components and components pre-coated thereby

The present invention relates to the use of a pre-coating process, which utilizes metallic plating as a surface pre-treatment for a ferrous-alloy precursor prior to applying a corrosion-inhibiting coating to improve the overall corrosion protection of the pre-treated and pre-coated component. Preferably the ferrous-alloy precursor is a heat-treatable, precipitation-hardenable stainless-steel material and the pre-treatment is a cadmium or a zinc-nickel alloy plating without a subsequent chromate or phosphate seal finish.

Self-tapping screw and its use

FIELD: tools. SUBSTANCE: invention relates to self-tapping screw and aimed at simplification of self-tapping screw making process. Self-tapping screw from austenitic or other stainless steel with body with thread shaping area and made by tip in form of drill. Body is entirely consists of austenite or other stainless steel and, at least in tip area is equipped with thin galvanically applied coating, therefore coated area is harder than not coated area, wherein thin coating has surface in manner of granulated or columnar structure, coating thickness is, at least, 2µΜ and preferably to 30 µm and has hardness ranging from 500 to 1,500 HV0.3 (Vickers hardness number). Self-tapping screw can be made easier, than conventional self-tapping screw, which is made in form of drill, tip consists of harder material, than body and is welded to stainless steel body. Thus, self-tapping screw is completely austenite self-tapping screw from main material, which is equipped with hard coating.
