  • Publication number: 20180238031
    Abstract: Disclosed is a dual size valve base that provides a fitted surface having indentations, protrusions and/or shaped surfaces that align with the lower surface of two different size valves, so that the valves fit within the valve base and do not rotate or otherwise move when secured to the valve base. The valve base has a sufficiently large platform to maintain a valve in a secure position underground on a support surface, so that the valve remains aligned with access pipes and access ports.

  • Patent number: 9011755
    Abstract: Disclosed are embodiments of an exercise step that utilize spirally shaped air-cushioning legs. The direction of the spiral of the air-cushioning legs is alternated around the periphery of the exercise step to eliminate rotational creep. Flow regulators are utilized to control the flow of air from the top of each of the air-cushioning legs into an interior portion of the base of the exercise step. Spokes provide an air flow passage between the air flow regulators and the central air regulator, as well as providing structural support for the base. Rings are also used around the base that inner connect the spokes and provide additional support. Recessed portions of a lower plate of the base are welded to an upper plate during a blow molding process to add additional support to the base of the exercise step.
