Abstract: A high strength dispersion strengthened aluminum alloy comprising an aluminum solid solution matrix strengthened by a dispersion of particles based on the compound Al3X, where Al3X has an L12 structure, is described. Various alloying elements are employed to modify the lattice parameter of the matrix and/or the particles so that the matrix and particles have similar lattice parameters. The alloy is produced by rapid solidification from the melt.

Abstract: A method for manufacturing an airfoil is provided which includes the steps of: a) providing a billet of discontinuously reinforced aluminum having at least 10 volume percent of silicon carbide as a reinforcing element, and no more than 30 volume percent of silicon carbide as the reinforcing element; 2) extruding the billet into an airfoil shaped geometry from a die, wherein the geometry includes a first wall, a second wall disposed opposite the first wall, a leading edge, a trailing edge disposed opposite the leading edge, and a first cavity disposed between the first and second walls, and the leading and trailing edges.

Abstract: An airfoil is provided having a cross-sectional geometry which includes a first wall, a second wall disposed opposite the first wall, a leading edge, a trailing edge disposed opposite the leading edge, and a first cavity. The first cavity is disposed between the first and second walls, and the leading and trailing edges. The cross-sectional geometry extends between a first and a second end, and the airfoil is formed from discontinuously reinforced aluminum.

Abstract: Plumbing fittings, such as joints, couplings, nipples, etc. are disposed within an opened topped container such that a plurality of the various fittings are disposed within the container. A transparent heat shrinkable film is shrunk onto the opened top container to removably secure the fittings therewithin. Each of the fittings has a removably adhered indicia bearing label secured thereto as well as the container, itself. In this way, the fittings can be sold within the package or may be removed therefrom for individual sales.

Abstract: A disposable umbilical clamp and cutter (10) for clamping a newly born infants umbilical cord in two places, then cutting the cord in between the two clamps (12,14). The clamps are separated and the infant retains its clamp (14) for a short period of time. The clamping surfaces (22) are formed in symmetrical upper (16) and lower (18) halves that rotate about a fold (20) of joining material. Each pair of halves form an enclosed cylinder around the centered umbilical cord when the clamps are closed. Break away connections (24) between the clamps keep them in a semi-rigid, side-by-side arrangement. The clamps are individually closed by putting pressure on two thumb rests (26,28), and opposing pressure with fingers on the lower halves (18), until latches (44) mate with corresponding latch stops (46). Clamps are clearly marked for use on the baby side (14) or the maternal side (12). A `V`-shaped blade (30) is located inside a vertical channel (32) in the maternal clamp (12).

Abstract: A self contained, hand held light in the form of a baton having a handle of cylindrical contruction that forms a battery compartment therewith. A bottom cap is removably received for closing the lower end of the handle and for actuating a switch means that is connected to be actuated by the cap. A bulb is supported at the upper end of the handle, and circuitry for the bulb supplies current flow from a storage battery by a conductor strip that is bent at the opposed marginal ends into a switch and a bulb holder. A hollow light transmitting cylinder is attached to the upper end of the handle, and a solid nose piece is attached to the upper end of the cylinder. This provides a water-proof device that is useful of signaling, controlling crowds, and illuminating dark areas.
