Patents by Inventor Edward Alyn Long

Edward Alyn Long 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).

  • Digitally controlled corrosion protection system and method
    Patent number: 10793955
    Abstract: At least one corrosion protection unit is located adjacent to a region of a structure immersed in an electrolyte. Each corrosion protection unit includes a circuit for applying rectified alternating current voltage between the structure and electrodes in the electrolyte. Each corrosion protection unit includes Reference Cells to produce direct current voltage between the Reference Cells and the structure, a measuring circuit coupled to the Reference Cells for measuring the potential between the Reference Cells and the structure, and a control circuit for controlling the level of the rectified alternating current voltage in accordance with the measured potential levels. Corrosion protection units are independent of one another, so that independently established rectified alternating current voltages are applied between different regions of the structure and e first and second corrosion protection units.
    Type: Grant
