Latest Patents

One of her notable inventions is a closure for an equipment sub. This closure features a generally cylindrical aperture leading to a bore and a bore stop. The design includes a circular body with an O-ring seal on a peripheral flange. A common actuating means moves spaced arcuate segments located on the circular body outwardly into contact with the bore stop provided in the bore of the equipment sub.

Another significant patent is for a method and apparatus for regulating gas flow. This invention showcases a pilot-operated, pressure-loaded, movable diaphragm-type gas-flow regulator valve used in flow control applications. The regulator body has an internal port arrangement that interconnects two independent throttling mechanisms in series. Two throttle plates are strategically positioned within the regulator valve body relative to an inlet chamber and an outlet chamber. A movable diaphragm is controlled by a separate pilot control system to adjust the area of the throttle plate exposed to flow, thereby varying the flow rate of the regulator valve. The design ensures stability at low-flow conditions while providing high capacity at maximum diaphragm lift. Additionally, the configuration of the throttle plates, inlet chamber, and outlet chamber significantly reduces operational noise by minimizing turbulent flow within the regulator valve body.
