  • Patent number: 8641384
    Abstract: The present invention provides a sump pump control system. The system includes a mounting fixture fabricated from a corrosion resistant material, and an electrical control comprising solid state electrical components supported by the mounting fixture. The sump pump control system also includes a diving bell cover. The diving bell cover has an open bottom, and is dimensioned to cover the electrical components. The diving bell cover is releasably secured to a support surface of the mounting fixture. The electrical control controls the operation of a sump pump. Should water rise to a level of the electrical components due to failure of the sump pump or due to quickly rising water, the diving bell cover will prevent water from contacting the electrical components. A method of removing water from a subterranean vault is also provided herein.

  • Patent number: 5524408
    Abstract: A method of repairing utility a pole having a section damaged by an accident or decay includes the steps of severing the utility pole above the location of the damage; removing the section of the utility pole including the damaged portion, and replacing the lower section of the utility pole with a steel stanchion having a platform thereon with a split socket disposed above the platform. The upper section of the utility pole is then laterally slid onto the platform through a window provided by opening the split socket upon removing one of two shells forming the split socket. The split socket is then closed by bolting one shell to the other. A space between the outer surface of the upper section of the utility pole and the inner surface of the split socket is then filled with urethane foam. The stanchion is made of a steel which forms a protective iron oxide coating, which coating is brown in color so as to match the brown color of the utility pole.
