The adhesive tape secures the tape wrapping in its spiral form with respect to the elongated core. The wrapped elongated structure may also structure may also included an elongated core, a first tape wrapping spirally wrapped around the core, an adhesive tape having two adhesive surfaces applied on the spiral first tape wrapping, and a second tape wrapping spirally wrapped around the adhesive tape.

Abstract: The invention relates to the utilization of a pyrolyzed carbon-containing ribbon which is wrapped about a brake disk core. The ribbon which is impregnated with a bonding agent forms an outer layer when wrapped about the core. An integral brake disk is formed upon pyrolyzation of the bonding compound.

Abstract: An improved method is provided for solving the age-old problem of wood-boring marine organisms. Wooden structures which are exposed to sea water can be protected from shipworm infestation by surrounding the structure with a nonwoven fabric having an effective pore size of less than 200 microns. Nonwoven fabrics of non-cellulosic organic or inorganic fibers are suitable. A self-bonded nonwoven fabric of polypropylene fibers is preferred. The fabric has high tensile and tear strengths, good puncture resistance, and a small effective pore size. The method may be used on new structures or old ones that are already infested with marine wood-borers.

Abstract: A novel golf shaft having a metal core and a graphite fiber reinforced sheath thereon is provided. The shaft has a predetermined orientation of the graphite fibers. In one embodiment, some longitudinal fibers are located in the region where the butt section of the shaft begins to taper downwardly thereby lowering the bending profile of the shaft compared with a shaft not having the longitudinal fibers. The method of fabricating the shaft also is disclosed.

Abstract: Method and apparatus for the surface coating and impregnation of the interstices of a moving porous web, and particularly method and apparatus for the production of elastomer-coated, bias-cut woven fabrics during a tentering operation. The coating apparatus disclosed consists of means for applying a layer of coating material sequentially to the lower and upper surfaces of the moving web to substantially penetrate the coating into the interstices of the web, while smoothing the surfaces to provide a uniform and controlled coating of desired thickness on the fabric.

Abstract: A tennis racket frame is constructed primarily of an elongated hollow tube member having a wall thereof consisting essentially of a plurality of concentric layers of high tensile strength fibers impregnated and bonded together by binder resin, at least two of the layers being helical windings of opposite unidirectional hands, and the head portion of a racket frame having a groove molded therein to receive the loop portions of the strings in recessed relation to the surrounding surface areas of the frame. The frames are made by a method including the use of a special mandrel on which the layers of fiber are wound under controlled conditions providing extra material in the head portion which is formed into the wall of the grooved portion of the head without affecting the overall sectional dimensions of the frame.

Abstract: A compound mica sheet is prepared by bonding a mica sheet to a woven fabric through a powdered epoxy resin with curing agent. The mica sheet holds a cured thermosetting resin composition impregnated therein and has an uncured epoxy resin composition including a curing agent impregnated therein. When thermosetting resin is forcedly impregnated, through vacuum/pressure impregnation, into a coil wound with the compound mica sheet which is adapted for use in medium and high voltage electric apparatus, and then cured, an excellent insulated coil is obtained.

Abstract: Large vessels such as tanks and the like are insulated by means of a spiral generation process thereby providing rapid application of the insulation with minimal labor. The process is particularly suited for operation in confined quarters.

Abstract: Resurfaced brake discs comprise a carbon disc and a wide tape of wear resistant material applied to the periphery of the disc, the tape being cut on one or both sides of the disc to allow the tape to be folded over the wearing surface of the disc. The tape is impregnated with a curable resin and heated under pressure to form a strongly adherent friction surface on the disc. Boron-containing or other additives may be added to the tape to improve friction qualities or to increase the oxidation resistance of the surface. Additional resin impregnations and heat treatments may be employed to strengthen the tape surface. The method is not limited to worn brake disc but may also be employed for resurfacing new brake discs as well.

Abstract: An improved hickey roller and method of making same is provided wherein such roller has a longitudinal axis and comprises an outer portion made of an elastomeric matrix having a substantially cylindrical outside surface and a plurality of elongated fibers having inner portions embedded in the matrix and outer portions extending outwardly from the cylindrical surface to define a brushlike construction. The elongated fibers are arranged approximately parallel to the longitudinal axis and the fibers have a denier ranging between 4 and 8 and each fiber has a cohesive strength which is greater than the cohesive strength of the matrix and greater than the adhesive force holding each fiber in the matrix.

Abstract: A three-dimensional composite structure with integral reinforcing ribs. The ribs have a core to include spaced metal inserts that are positioned to accept load bearing fasteners. A lightweight reinforcing material fills the remainder of the core. An adhesive tape with continuous filament composite fibers encircle the rib. The ribs are positioned between an inner and outer shell of structurally reinforced plastic and wound circumferentially and laterally with continuous filament composite tape.

Abstract: A tape dispenser for use in winding tape about a rotating body generally includes a frame mounted on a base with adhesive tape mounted on a reel on the frame. The tape is run from the reel to a holding means which in the preferred form is a vacuum surface which holds the tape thereon but permits it to slide along the surface. The tape is fed in a manner in which the adhesive side faces outward from the vacuum surface. The dispenser has displacement means which pivots the frame and moves it toward the rotating body until the body touches the adhesive of the tape at or near the vacuum surface. The rotation of the rotating body causes tape to be payed from the reel until a predetermined length of tape is wound around the body. Thereafter, it is cut between the body and the vacuum surface.

Abstract: An improved method and article are provided for cryogenic construction and the article is particularly useful when employed with the spiral generation method of applying insulation. An insulating member is provided having a face member having an elongate cross-section and a plurality of backing members also of elongate cross-section adhered to a face of the backing member. Fracturing of the insulation on temperature cycling is substantially reduced.
