John Haarsma 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).

  • Insulating material and use thereof in insulators
    Patent number: 4690780
    Abstract: An improved insulating material is provided. The insulating material is a mixture of an insulating fluid and solid insulative bodies. The insulating material exhibits desirable insulating, conformal coating, surface adhesion, and low-viscosity characteristics. For example, when the insulating material is used to fill the cavity of a hollow insulator, the insulating material prevents any moisture that enters the insulator from adhering to the walls that define the cavity; thus maintaining the insulating qualities of the insulator. In the event that some of the fluid is lost through leakage, the insulating material also aids in preserving the insulating qualities of the insulator.
    Type: Grant
    Filed: July 1, 1986
    Date of Patent: September 1, 1987
    Assignee: S&C Electric Company
    Inventors: Leonard V. Chabala, John Haarsma, Raymond P. O'Leary, Christopher D. Roman, Thomas J. Tobin
