  • Method and composition for inhibiting general and pitting corrosion in cooling tower water
    Patent number: 5376331
    Abstract: A method of inhibiting the pitting corrosion rate of carbon steel in a cooling tower system comprising adding to a cooling tower water an effective amount of a corrosion inhibiting composition containing from about 1 to about 10 ppm of a water soluble molybdate, calculated as molybdate and from about 5 to about 25 ppm of a stabilized phosphate, calculated as phosphate, the corrosion inhibiting composition being substantially free of active zinc, and circulating the water in the system.
    Type: Grant
    Filed: April 16, 1993
    Date of Patent: December 27, 1994
    Assignee: Gulf Coast Performance Chemical, Inc.
    Inventors: Bradley A. Bucher, Jesse H. Jefferies
  • Apparatus and method for washing exterior building surfaces
    Patent number: 5249326
    Abstract: A system for washing building windows and other exterior surfaces. The system uses substantially pure water as the washing medium, and uses a novel cable restraint system for restraining an automatic cleaning device against the building surface.
    Type: Grant
    Filed: June 5, 1990
    Date of Patent: October 5, 1993
    Inventors: James E. Jefferies, Jesse H. Jefferies, Brad A. Bucher

  • Method of preventing corrosion by contaminated cooling tower waters
    Patent number: 4867944
    Abstract: A method of inhibiting corrosion in cooling tower systems comprising adding to a cooling tower water containing sulfides, hydrocarbons or mixtures thereof as contaminants a corrosion inhibiting composition containing a water-soluble zinc compound, a water-soluble molybdate, a water-soluble orthophosphate and a water-soluble polyphosphate.
