Patents by Inventor Alfred E. Woodson

Alfred E. Woodson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process of inhibiting scale formation with mixtures of thio-, oxygen or thio-oxygen phosphates and pyrophosphates
    Patent number: 4051029
    Abstract: Mixtures of Thiophosphates, pyrophosphates containing both oxygen and sulfur, and oxygen phosphates are effective as scale inhibitors. The mixtures are synergistically more effective as scale inhibitors than each component individually.These synergistic mixtures are also effective for other uses such as for inhibiting corrosion, particularly in aqueous and/or oxygenated systems.
    Type: Grant
    Filed: June 26, 1975
    Date of Patent: September 27, 1977
    Assignee: Petrolite Corporation
    Inventors: Derek Redmore, Alfred E. Woodson
  • Process of inhibiting corrosion of metal in an aqueous environment with mixtures of thio-, oxygen and thio- oxygen phosphates and pyrophosphates
    Patent number: 4042323
    Abstract: Mixtures of Thiophosphates, pyrophosphates containing both oxygen and sulfur, and oxygen phosphates are effective as corrosion inhibitors particularly in aqueous and/or oxygenated systems. The mixtures are synergistically more effective as corrosion inhibitors than each component individually.These synergistic mixtures are also effective for other uses such as for scale preventatives, etc.
