Patent number: 5202365Abstract: The problem of the potential for creation of a reactive noncompressible crust in a fluid adhesive mixture comprising a deposit of an uncured curable fluid curable resin composition and a deposit of a fluid curing agent wherein the deposits are separated by a thin flexible barrier film formed from the interaction of the cured resin as reacted by the curing agent, is overcome by including with the fluid curing agent a thickener in an amount sufficient to render the fluid curing agent non-free-flowing at room temperature and preventing the formation of any substantial amount of noncompressible crust in the mixture.Type: GrantFiled: June 13, 1991Date of Patent: April 13, 1993Assignee: Reactive Industries, Inc.Inventor: Richard B.

Patent number: 5000636Abstract: The method of making a friction locking fastener of the type having in the thread grooves a first deposit formed of a mixture of an uncured epoxy resin and a radiation-curable, film-forming material, and a second deposit of a fluid curing agent and a radiation-curable, film-forming material. The deposits are made in the thread grooves at circumferentially spaced locations so that a very thin coating of the radiation-curable, film-forming material develops at the surface of each deposit. The deposits are subjected to high intensity ultraviolet radiation for a few seconds to transform the coatings developed on the surfaces of the deposits into thin, continuous, flexible, non-tacky protective films which cover the still fluid deposits in the thread grooves of the article. Alternatively, when one or both the resin and curing agent are micro-encapsulated. They may be contained in a single mixture which includes the radiation-curable material.Type: GrantFiled: July 11, 1989Date of Patent: March 19, 1991Assignee: The Oakland CorporationInventor: Richard B.

Patent number: 4891244Abstract: A method of making locking threaded fasteners having on the threaded surfaces thereof locking patch material formed by the accumulation of fused thermoplastic resin particles. The fasteners are advanced through a heating zone followed by an application zone. The fasteners are heated while in the heating zone to a temperature sufficient to fuse thermoplastic resin particles received on the threaded surfaces in the application zone. Thermoplastic resin particles are applied to the fasteners in the application zone by a mechanical propelling device which comprises a rotatable slinger that propels the particles by centrifugal force against the heated threaded surfaces. The thermoplastic resin particles build up on the threaded surfaces and fuse into locking patches. Apparatus for carrying out the method is also disclosed.Type: GrantFiled: February 21, 1989Date of Patent: January 2, 1990Assignee: The Oakland CorporationInventor: Richard B. Wallace

Patent number: 4545712Abstract: A threaded fastener having a deposit of a fluid polymerizable resin in the bottoms of the thread grooves, a fluid polymerizing agent overlying the resin in the thread grooves, and a strong non-tacky protective film covering the agent. The fluid resin and agent have therebetween a barrier film as a result of polymerization of the resin where it contacts the polymerizing agent. Preferably, the fluid resin and agent deposit includes abrasive particles, such as table salt to enhance mixing when the fastener engages a mating threaded member. In production, the protective film is applied as an aqueous solution of PVA, which is rapidly converted to the non-tacky film by the application of a desiccant powder such as a derivative of guar gum.Type: GrantFiled: August 11, 1983Date of Patent: October 8, 1985Assignee: The Oakland CorporationInventor: Richard B.

Patent number: 4508759Abstract: A threaded fastener having an annular ring of yieldable friction material in the thread grooves thereof and bonded to the sides of the threads, in which the material is of substantially uniform thickness on the sides of the threads from adjacent the root to adjacent the crest thereof. In an embodiment of the invention two more adjacent but axially separated rings of friction material are provided, the annular zone or zones between adjacent rings having much less or substantially no friction material. In another embodiment, the friction material is applied primarily to the non-load bearing side of the threads in the ring.Type: GrantFiled: January 10, 1983Date of Patent: April 2, 1985Assignee: The Oakland CorporationInventor: Richard B.
