  • Method for controlling snails using dialkyl diallyl ammonium polymers
    Patent number: 6315910
    Abstract: A method for controlling snails in aqueous systems which involves treating aqueous systems which contain snails or which are prone to snail infestation with an effective amount of a water-soluble dialkyl diallyl quaternary ammonium polymer (polyquat) is disclosed. A preferred polymer is a poly(quaternary ammonium) compound having a recurring structure (DMDAAX−) resulting from the polymerization of monomeric dimethyl diallyl ammonium X−, wherein X− is any suitable anion.
    Type: Grant
    Filed: March 3, 1999
    Date of Patent: November 13, 2001
    Assignee: Calgon Corporation
    Inventors: James E. Farmerie, James K. Dicksa

  • Slurry electrowinning apparatus
    Patent number: 4096053
    Abstract: Apparatus for continuous electrowinning of copper bearing slurries, including an electrowinning cell wherein a slurry composed of a suitable electrolyte and a copper-bearing solid material, is subjected to the simultaneous reactions of dissolving the copper material and plating out elemental copper as a relatively pure copper product. The apparatus and process also includes means to purify the copper-bearing material before passage to the electrowinning cell so as to prevent contamination of the electrolyte in the cell and, also, a means to recover sulfur which is released during the electrowinning and unreacted copper material.
    Type: Grant
