  • Publication number: 20220258554
    Abstract: A kinetic energy shock absorber is shown and described. The kinetic energy shock absorber is comprised of a sleeve that has a first closed end and a second opened end. A piston is sized to fit within the sleeve and has at least one dosed end. The closed end of the sleeve has a protrusion attached to the closed end, wherein the protrusion has an aperture located therethrough. The dosed end of the piston has a protrusion, wherein the protrusion has an aperture therein. The piston will create electric energy when it enters the sleeve via an electric generation device. The kinetic energy shock absorber is a device that may be attached to an existing vehicle shock. The kinetic, energy shock absorber may also be used as a replacement shock for a motor vehicle.

  • Patent number: 9175536
    Abstract: An open-ended pipe engagement device with a saddle portion that attaches around an open pipe, a structural platform comprising a tapering plug, support bars to prevent dislodgement of the device and threaded rods to winch the platform and plug onto the pipe end to be sealed. The device provides a means to safely cap and plug a leaking pipe end and allow the pipe to resume normal activity thereafter. The saddle portion provides a structural a base from which the plug and associated platform are positioned and winched into place, counteracting any fluid pressure exiting the leaking pipe. The plug comprises a tapering and conforming structure with a centrally located through hole for which to direct fluid as the platform is lowered and once the plug is engaged. Above the plug and through the platform is a section of pipe for which to direct the leaking fluid after the apparatus has been secured to the end of the pipe, effectively controlling the leak and allowing normal operation of the well to resume.
