  • BARREL CHAMBERING METHOD AND APPARATUS
    Publication number: 20040244255
    Abstract: A method of machining a chamber in a gun barrel by EDM, by using a conductive electrode which defines the desired shape and dimensions of the chamber. A series of electrodes of progressively increasing diameter may be used. An electrode for an EDM barrel chambering process is an axisymmetrical conductive member, and may include a body, an angular shoulder, a neck, throat area, and a tapered lead angle portion into the bore along with other features of a selected cartridge chamber.

  • Metal alloys for the reflective or the semi-reflective layer of an optical storage medium
    Patent number: 6007889
    Abstract: A copper-based or silver-based alloy thin film is provided for the highly reflective or semi-reflective layer of optical discs. Alloy additions to silver include gold, palladium, copper, rhodium, ruthenium, osmium, iridium, and platinum. Alloy additions to copper include silver, cadmium, gold, magnesium, aluminum, and nickel. These alloys have moderate to high reflectivity and reasonable corrosion resistance in the ambient environment.
