摘要： A shoe is provided with a spring mechanism in the heel area. The spring includes a pair of generally circular end portions which are supported by the outsole and a beam portion which extends between the end portions. Initial impact cushioning is provided by resilient deflection of the end portions and compression of surrounding materials. The main cushioning is provided by linear deflection of the beam portion. Overload protection is provided by restorable collapsing of the cross section of the beam.

摘要： A method for protecting an aircraft component from ice formation uses a thermally conductive film. The film includes a polymer, an electrically conductive material, and a sufficient concentration of hexagonal boron nitride to provide adequate heat transfer properties, and have high thermal conductivity, peel strength, and shear strength. The films can include thermoset polymers, thermoplastic polymers, or blends thereof, and can also include reinforcing materials such as fiberglass, carbon fiber, metal mesh, and the like, and thermally conductive fillers, such as aluminum oxide, aluminum nitride, and the like. The films can be included in composite materials. The films can be used as part of a layered structure, and used in virtually any application, for example, various locations in aircraft, where heating is desirable, including nacelle skins, airplane wings, heated floor panels, and the like.

摘要： A frame for a game racquet such as a tennis racquet is formed by interspersed winding of filament material over an elongated mandrel to form a tube. The tube is formed from a wound laminate in which some or all of the circuits of the wind patterns are sequenced in an arbitrary manner by the designer. Each circuit is helically wound along a rotating mandrel. The formed tube is placed in a mold having the shape of the frame, auxiliary pieces for handle and yoke sections are added, and together molded to form the frame.

摘要： A frame for a game racquet such as a tennis racquet is formed by helically winding a tow of filament material and thermoplastic material over an elongated mandrel to form a tube. The tube is positioned in a mold having the shape of a game racquet frame and auxiliary pieces for handle and yoke sections are added. This preform is heated to melt the thermoplastic while the interior of the tube is pressurized. The preform is then allowed to cool and harden to form the game racquet frame.
