  • Low expansion superalloy
    Patent number: 4066447
    Abstract: Nickel-iron and nickel-iron-cobalt alloys contain chromium and gamma-prime hardening elements in proportions balanced according to special compositional relationships providing desired thermal expansion, inflection temperature, strength and ductility characteristics, particularly including notch strength needed in machinery and structures subjected in use to varying temperatures and thermal gradients where operating temperatures become elevated above 500.degree. F.
    Type: Grant
    Filed: July 8, 1976
    Date of Patent: January 3, 1978
    Assignee: Huntington Alloys, Inc.
    Inventors: Darrell Franklin Smith, Jr., Edward Frederick Clatworthy, Donald Edward Wenschhof, Jr.
  • Matrix-stiffened heat and corrosion resistant wrought products
    Patent number: 4058416
    Abstract: Matrix-stiffened nickel-iron-chromium-columbium solid-solution alloy with excellent metallurgical stability has heat-resistant and corrosion resistant characteristics especially useful for articles needed to sustain stress in long-time service at elevated temperatures, particularly including superheater tubing in steam power plants. Alloy also has good workability and thermal response characteristics for commercial production of heat-treated wrought products.

  • Die changing turret table segment
    Patent number: 3961549
    Abstract: A turret worktable for a turret punch machine tool with the table aligned adjacent to the top of the die turret, the dies extending below the table top. The top has a section thereof extending from an edge of the table to the edge of the lower die turret, which is pivotable through an arc from an operating position adjacent to the die turret and plainer with the remainder of the table to a die removal position located below and to the side of the dies in the lower die turret. The segment forms a worktable top when in the die changing position.
