Abstract: The present invention provides a self-closing hinge suitable for use in a variety of applications where it is desirable to provide for automatic closing of a hinged member in a delayed or slow fashion. The invention includes a generally cylindrical outer casing or housing that partially encloses a rotatable shaft that may be secured to a hinged member to effect the rotation thereof. The shaft is disposed within a recess in a cylindrical coupler that is engaged by the shaft during rotation in a first direction—generally an “open” rotational direction—and that engages the shaft to rotate it in a second direction—generally a “closed” rotational direction. The coupler is secured to a torsional spring that acts against the open rotation of the shaft and thereby forces the coupler to rotate in a closed direction. Additionally, a rotatable inner casing, which is generally cylindrical, may be disposed within the outer casing in close proximity thereto, such that a high viscosity fluid may be disposed therebetween.

Abstract: An improved method and apparatus for the manufacturing of advanced composite tubes involving the steps of wrapping various layers, including a composite layup, around an elongated mandrel, placing the mandrel with layers applied in a tubular female mold, expanding the diameter of the mandrel, thus forcing the various layers to compress against the surface of the female mold.In order to remove excess resin from the layup this method also incorporates a resin absorbing layer which is wrapped around the mandrel prior to the composite layup. In addition, all the layers necessary to produce the tube are wrapped around the mandrel with a wrapping apparatus in which the various layers are first placed flat on a sheet. The sheet is then pulled around the mandrel, mechanically transferring the various layers to the perimeter of the mandrel. This method results in the formation of high quality composite tubes with smooth external surface finishes.
