  • Submersible appartus for generating electricity and associated method
    Patent number: 6109863
    Abstract: A fully submersible apparatus for generating electricity from liquid flow as in an ocean or river current. A buoyant structure is fully submersible and has at least one pair of counter-rotating side-by-side motors with a plurality of angularly spaced radial vanes each having a plurality of rotatable subvanes such that current impinging upon the motor will impinge on a closed or solid vane to effect rotation of the motor and its shaft during a first phase of the rotational cycle and will impinge on open vanes for free passage therethrough on the return or second phase of rotation of the motor. Motors may also be provided with vanes in overlying and underlying relationship. An associated method is provided.

  • Process for making cementitious mine backfill in a salt environment using solid waste materials
    Patent number: 5551806
    Abstract: The present invention generally relates to a method for hydraulically backfilling empty mined salt cavities. The method comprises combining at least one pozzolanically active waste material with an effective amount of a cementing agent and brine to form a pozzolanic mixture, wherein the relative proportions of said pozzolanically active waste material, alkaline earth metal hydroxide or alkaline earth metal oxide and saturated brine are sufficient for reaction under conditions in said salt cavity to form a stable, low porosity, load bearing pozzolanic cement; oxidizing said pozzolanic mixture in order to substantially remove aluminum metal from the mixture; and hydraulically depositing said pozzolanic mixture in the empty salt cavity.

    Abstract: The present invention generally relates to a method for hydraulically backfilling empty mined salt cavities. The method comprises combining at least one pozzolanically active waste material with an effective amount of an alkaline earth metal in the form of an alkaline earth metal hydroxide or alkaline earth metal oxide and saturated brine to form a pozzolanic mixture, wherein the relative proportions of said pozzolanically active waste material, alkaline earth metal hydroxide or alkaline earth metal oxide and saturated brine are sufficient for reaction under atmospheric conditions in said salt cavity to form a stable, low porosity, load bearing pozzolanic cement; and hydraulically depositing said pozzolanic mixture in the empty salt cavity.
