  • Patent number: 8871143
    Abstract: Hardened amalgams formed from copper mixed with liquid gallium or liquid gallium-indium alloys are used to fabricate sputter targets comprised of copper, gallium and indium (CIG) and targets of selenides of copper, gallium and indium (CIGS). Amalgam hardening occurs by formation of intermetallic compounds at or near ambient temperature as a result of reaction between liquid metals and solid metals in powder form.

  • Publication number: 20140314615
    Abstract: A method for measuring an apparent density of a metal powder includes holding a metal powder in a vessel, applying an alternating magnetic flux to the metal powder using an exciting coil disposed outside the vessel, detecting the alternating magnetic flux passed through the metal powder using a search coil disposed outside the vessel, and determining an apparent density of the metal powder from an amplitude of the detected alternating magnetic flux using a calibration curve representing a correlation between the apparent density of the metal powder and the amplitude of an alternating magnetic flux prepared in advance. The method enables to measure the apparent density of a metal powder with a high precision in an on-line and non-contact manner without stopping a process of producing a mixed powder or a process of producing a powder compact.

    Abstract: A crankcase explosion relief valve with an external flame trap made from compressed and sintered porous metal powder. Should an explosion take place, the valve plate will lift, allowing the flame front and exhaust gasses to enter the device. The exhaust gasses exit the valve though a circular flame trap made of porous metal. The circular flame trap is of a ribbon shape as to increase the amount of permeable area on the component. Due to the narrow interconnected porosity, flames will not be able to propagate past the porous material, while the exhaust gasses are able to freely pass through. In another embodiment, the porous material component is in the form of a plurality of cups.
