Patent number: 4741873Abstract: Rigidized composite preforms are fabricated by first serving individual reinforcement strands with a thread of a thermoplastic material. After shaping the reinforcement strands into a desired geometry, the shaped strands are heated to melt the thermoplastic threads. By then cooling the shaped reinforcement strands, the thermoplastic material solidifies and acts as an adhesive or glue in holding the preform together in a rigid fashion. Such rigid preforms are particularly suitable for handling, storage and transportation to other locations and media prior to densification. Densification may be performed by conventional techniques to produce the final composite article. Pyrolysis of the matrices and subsequent densification of the matrix may be accomplished.Type: GrantFiled: April 15, 1986Date of Patent: May 3, 1988Assignee: Kaiser Aerotech, a Division of Sowa & SonsInventors: Mel J.

Patent number: 4577543Abstract: A generally cylindrical member, such as a catheter, cannulae, or the like, has a monolithic construction. An inner core of plastic is passed through a conventional reinforcing apparatus, such as a conventional braiding mechanism. The braiding action is interrupted at predetermined intervals while the core continues to be fed so that straight reinforcing strand lengths are disposed on the outer surface of the inner core at predetermined lengths. The member passes through a heated sizing die to adhere the braided strand to the inner core, and a mechanical shear or rotating blade cuts the straight strand lengths off so that they are detached from the core. An over-extrusion of plastic may be provided to encapsulate the reinforcing strands. When the catheter is free of reinforcing strands it is relatively soft and flexible--such as at its tip--and where the reinforcing strands are provided it is relatively stiff. The monolithic construction ensures that components will not detach in a patient's body.Type: GrantFiled: August 18, 1983Date of Patent: March 25, 1986Assignee: American Hospital Supply CorporationInventor: Bruce C.

Patent number: 4311079Abstract: A faired article comprising a cable having a core surrounded by a braided jacket is provided with at least one row of fairing loops extending lengthwise of the jacket for the purpose of reducing strumming, drag and cable fatigue when the cable is installed underwater. The faired article is manufactured by guiding a length of fairing yarn into proximity with the upstream side of the ring of a braider, entraining the fairing yarn in an air stream directed across the path of movement of the braid yarns inside the braider ring, and causing the fairing yarn entrained therein to pass through the path of movement of the braid yarns as they advance around the braider ring, thereby enabling the braid yarns to form the fairing yarn into loops as the braid yarns form the jacket around the core. Preferred apparatus for practicing the method of the present invention is also disclosed.Type: GrantFiled: August 25, 1980Date of Patent: January 19, 1982Assignee: Wall Industries, Inc.Inventor: Henry A.

Patent number: 4258608Abstract: Disclosed herein is a snubbing device for use with traditional braided cordage. Traditional braided cordage exhibits a certain elasticity when tensioned by having the longitudinal axis of the braided cordage pulled in such a manner that the braid and resulting diameter constricts itself. In a double braided environment, an outer braid would constrict upon an inner braid, which would in turn constrict upon itself. A resilient elastic insert is provided within the inner core thereof, thereby causing the inner braid to constrict thereon.Type: GrantFiled: February 14, 1979Date of Patent: March 31, 1981Inventor: John L.

Patent number: RE31197Abstract: A telephone cord which is particularly suited for use with some models of decorative telephones includes a plurality of individually insulated conductors, a plastic jacket which encloses the plurality of individually insulated conductors, and a braid which encloses the plastic jacket. While the braid is comprised of a woven band of cloth of a natural material or a synthetic material, in a preferred embodiment it is made of cotton which is dyed to a color which is compatible with that of portions of the decorative telephone. An end portion of the cord which is terminated with a modular plug that is capable of being inserted into a jack in the telephone is treated to cause the braid to be bonded to the plastic jacket so that when the jacket is removed to expose the conductors for purposes of plug termination, the braid will not fray.Type: GrantFiled: April 9, 1982Date of Patent: April 5, 1983Assignee: Western Electric Company, Inc.Inventor: Eugene R.
