  • Thermally stable emulsion explosive composition
    Patent number: 4322258
    Abstract: The invention relates to a thermally stable, cap-sensitive water-in-oil emulsion explosive composition having a discontinuous aqueous oxidizer salt solution phase containing calcium nitrate, a continuous oil or water-immiscible liquid organic phase, an emulsifier, and a density reducing agent.
    Type: Grant
    Filed: November 9, 1979
    Date of Patent: March 30, 1982
    Assignee: IRECO Chemicals
    Inventors: Walter B. Sudweeks, Larry D. Lawrence
  • Emulsion blasting composition
    Patent number: 4216040
    Abstract: The invention relates to water-in-oil emulsion blasting agents having a discontinuous aqueous phase, a continuous oil or water-immiscible liquid organic phase, and an emulsifier having an unsaturated hydrocarbon chain for its lipophilic portion.
    Type: Grant
    Filed: January 19, 1979
    Date of Patent: August 5, 1980
    Assignee: IRECO Chemicals
    Inventors: Walter B. Sudweeks, Harvey A. Jessop
  • Emulsion blasting agent
    Patent number: 4141767
    Abstract: The invention relates to emulsified aqueous explosive blasting compositions having a discontinuous aqueous phase, a continuous oil or water-immiscible liquid organic phase, and a fatty acid amine or ammonium salt emulsifier having a chain length ranging from 14 to 22 carbon atoms.
    Type: Grant
    Filed: March 3, 1978
    Date of Patent: February 27, 1979
    Assignee: IRECO Chemicals
    Inventors: Walter B. Sudweeks, Harvey A. Jessop
  • Ore separating method and apparatus
    Patent number: 4071143
    Abstract: The invention relates to a method and apparatus for separating ore. The apparatus includes a rotatable conical cap having a rounded top, inwardly curving sides and a riffle extending vertically from the circumference of the base. An ore-water slurry is allowed to flow down the sides of the rotationally agitating cap and into the riffle, which retains the heavy metals but allows the tailings to be carried over the riffle. The inward curvature of the sides cause centrifugal separation of the metals from the tailings in the slurry stream.

    Inventor: Max R. Richan
  • Aqueous blasting composition with crystal habit modifier
    Patent number: 4055449
    Abstract: The stabilization of a fine dispersion of an immiscible liquid hydrocarbon fuel throughout an aqueous blasting composition having a continuous aqueous phase is accomplished by the use of a crystal habit modifier to reduce the crystal size of the oxidizer salt in the composition. Such reduction is found to be critical for stabilizing the fine dispersion of immiscible hydrocarbon fuel droplets throughout the composition and resultantly for maintaining the sensitivity of the composition to detonation.
    Type: Grant
    Filed: August 11, 1976
    Date of Patent: October 25, 1977
    Assignee: Ireco Chemicals
    Inventor: Daniel A. Wasson
  • Card key and/or coin holder
    Patent number: 4037716
    Abstract: The invention is a pocket-sized card holder for keys, coins and/or similar items comprised of a thin card having a depressed region therein for receiving and containing the items and a pressure resealable, at least partially adhesively-coated lid which covers the depressed region and which can be stripped or peeled back to expose the contained items. The holder is preferably of credit card size for convenience in carrying, with overall thickness only fractionally greater than the items contained.

    Inventor: John D. Marks
  • Blasting composition containing calcium nitrate and sulfur
    Patent number: 4032375
    Abstract: The present invention relates to improved explosives or blasting compositions of the aqueous gel or slurry type. In general, it concerns such blasting compositions employing a combination of calcium nitrate as oxidizer salt and sulfur as fuel. This combination effectively sensitizes the composition and renders its sensitivity relatively less dependent upon temperatures. In addition, this combination imparts desirable physical properties to the composition.
