Patent number: 9669579Abstract: A method for forming a structural member and a structural member produced thereby includes positioning a first composite section and a second composite section within a tool. The tool has an inner surface and a wall intersection and is supported by a tool platform. The tool platform and a pressure platform are relatively movable between an open position and a closed position. The tool has a non-planar outer surface against which the member may be pressed. A composite splice member is positioned at least partially overlapping both the first composite section and the second composite section to form a joint in the composite structural member. The composite structural member is pressed against the non-planar outer surface of the tool by applying pressure to the joint from a pressure bladder. Heat is applied to the composite structural member at the joint to cure the composite splice member to the first composite section and the second composite section.Type: GrantFiled: September 17, 2014Date of Patent: June 6, 2017Assignee: THE BOEING COMPANYInventors: William T.

Patent number: 5397527Abstract: Yarns are prepared by spinning PEN or other semi-crystalline polyester polymers made from similarly rigid monomer combinations to a state of optimum amorphous orientation and crystallinity. This is accomplished by selection of process parameters to form an undrawn polyester yarn of birefringence at least 0.030. The spun yarn is then hot drawn to a total draw ratio of between 1.5/1 and 6.0/1 with the resulting drawn semi-crystalline polyester yarn having Tg greater than 100.degree. C. and a melting point elevation at least 8.degree. C. The preferred yarn has a tenacity at least 6.5 g/d, dimensional stability (EASL+Shrinkage) of less than 5%, and shrinkage 4% or less. The resulting yarn exhibits surprisingly high modulus and tenacity together with low shrinkage when compared to prior art yarns.Type: GrantFiled: September 13, 1993Date of Patent: March 14, 1995Assignee: AlliedSignal Inc.Inventors: Peter B.

Patent number: 4090635Abstract: A container such as a metal top can containing a liquid to be dispensed by perforating the can top has an annular metal top having a concentric opening sealed with an easily perforatable thin film material. The thin film material extends across adjacent to the undersurface of the annular metal top and is sandwiched between the container top and the can body at the rim in a usual rim bead crimping operation, which leaves a projecting edge portion of the thin film outside of the rim. This edge of the film is then melted away by a hot sleeve or by spinning the sealed can relative to a hot element. The thin film material, which may be a polyester plastic, is selected to be sufficiently strong to protect the container contents during normal handling yet is more readily perforatable than the container top itself would be.Type: GrantFiled: July 13, 1976Date of Patent: May 23, 1978Assignee: The Nelson CompanyInventors: Evan S.
