  • Method for magnetic/ferrofluid separation of particle fractions
    Patent number: 6994219
    Abstract: A particulate feed comprising a first particle type and a second particle type is separated by providing a separation apparatus having a separation vessel having a top and a bottom, and wherein the separation vessel includes inwardly sloping side walls. A magnet structure has a first pole positioned exterior of and adjacent to each of the side walls of the separation vessel, and a second pole positioned above the separation vessel. A mixture of the particulate feed and a ferrofluid is introduced into the separation vessel, and the particulate feed is separated into a first particle fraction comprising a majority of the first particle type, which sinks in the separation vessel, and a second particle fraction comprising a majority of the second particle type which floats in the separation vessel.

  • Quasi-isothermal forging of a nickel-base superalloy
    Patent number: 6932877
    Abstract: A forging blank of a forging nickel-base superalloy is forged in a forging press having forging dies made of a die nickel-base superalloy. The forging is accomplished by heating the forging blank to a forging-blank starting temperature of from about 1850° F. to about 1950° F., heating the forging dies to a forging-die starting temperature of from about 1500° F. to about 1750° F., placing the forging blank into the forging press and between the forging dies, and forging the forging blank at the forging-blank starting temperature using the forging dies at the forging-die starting temperature, to produce a forging.
