  • Cooling fluid for fabrication operations
    Patent number: 4869839
    Abstract: The present invention relates to a cooling fluid for metal cutting, drilling, grinding and other fabricating operations comprising a compound of the formula C.sub.6 H.sub.4 (OH)COOR, where R is selected from the group consisting of --H,--CH.sub.3, --C.sub.2 H.sub.5,--C.sub.3 H.sub.7, and --C.sub.4 H.sub.9, a ketone with a boiling point of at least about 150.degree. F., and an at least partially soluble acid.The present invention also relates to a process and fluid product made by a certain process for cooling tools and workpieces for metal cutting, drilling, grinding and other fabricating operations comprising the steps of mixing a compound of the formula C.sub.6 H.sub.4 (OH)COOR, where R is selected from the group consisting of --H,--CH.sub.3,--C.sub.2 H.sub.5,--C.sub.3 H.sub.7, and --C.sub.4 H.sub.9, a ketone with a boiling point of at least about 150.degree. F.

  • 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.
