  • Patent number: 10407745
    Abstract: A method of producing an article selected from a titanium article and a titanium alloy article comprises melting feed materials with a source of hydrogen to form a molten heat of titanium or a titanium alloy, and casting at least a portion of the molten heat to form a hydrogenated titanium or titanium alloy ingot. The hydrogenated ingot is deformed at an elevated temperature to form a worked article comprising a cross-sectional area smaller than a cross-sectional area of the hydrogenated ingot. The worked article is dehydrogenated to reduce a hydrogen content of the worked article. In certain non-limiting embodiments of the method, the dehydrogenated article comprises an average ?-phase particle size of less than 10 microns in the longest dimension.

  • Patent number: 7004332
    Abstract: A disc screen apparatus for classifying a stream of mixed recyclable materials of various sizes and shapes, including newspaper, clean mixed paper, magazines, plastic bottles, glass bottles and jars, cans, and the like. The apparatus has an inclined fixed first disc screen section and an inclined articulating second disc screen section whose angle of inclination can be independently adjusted via a hydraulic cylinder or other angular adjustment mechanism in order to improve the separation of newspaper and/or clean mixed paper without impairing the ability of the fixed disc screen section to separate mixed containers. The first and second disc screen sections are supported by first and second frames that carry the parallel driven shafts and discs that form the disc screen sections. The frames have complementary mating surfaces that limit the range of articulation of the second disc screen section.

  • Patent number: 6648145
    Abstract: A disc screen apparatus has a V-shaped configuration with a lowermost region that provides a laterally inclined trough that receives the mixed recyclable materials. Broken glass falls downwardly between the discs of the lowermost region. Plastic milk bottles and soda pop containers tumble down the trough and eventually fall off its lower end. Newspaper is conveyed upwardly over the terminal upper ends of a pair of vertically inclined regions of the disc screen apparatus. The frame of the disc screen apparatus can incorporate ducting for connecting a source of pressurized air to one or more air manifolds the blow air toward the vertically inclined regions for helping the discs in these regions convey newspaper up the inclined regions and over their terminal upper ends. The angle of inclination of the vertically inclined regions may be adjustable to optimize the efficiency of classification.

    Abstract: A disc screen apparatus is disclosed for separating mixed recyclable materials of varying sizes and shapes. The disc screen apparatus has an enclosure or frame with an input, a container discharge location and a paper discharge location. A first plurality of shafts and second plurality of shafts are rotatably supported by the frame. The first plurality of shafts form a first disc screen disposed in a first plane and the second plurality of shafts form a second disc screen at least a portion of which is disposed in a second plane. The second plane is disposed beneath and angled with respect to the first plane such that the planes at least partially overlap. One or more motors rotate the first and second plurality of shafts. Each shaft has a plurality of discs positioned along it. The discs are offset between adjacent shafts such that discs on each shaft interleave with discs on an adjacent shaft but do not touch the adjacent shaft. The discs are substantially square in shape with radiused corners.

  • Patent number: 5924834
    Abstract: A machine agitates and rips scrap metal containers such as scrap aluminum cans to expose their interiors and shake out sand, dirt, and other material in the cans. Alternatively, the containers may comprise shell casings which the machine deforms by thrashing. The machine has an enclosure in which a rotatable shaft is supported. A plurality of blade sets are mounted on the shaft within the enclosure to rotate the shaft. The blade sets are distributed along the shaft and interleaved with a plurality of angled, stationary vanes that are mounted to an inside surface of the enclosure. These parts cooperate when the shaft is rotated by propelling containers on a helical path on which the blade sets batter, thrash, and rip the containers, throwing them against the vanes and the sides of the enclosure. As cans are battered and agitated by the blades, their contents are emptied and the cans are ultimately propelled to a collection point.
