  • Expandable tubulars for use in geologic structures
    Patent number: 8800650
    Abstract: An expandable tubular includes a plurality of leaves formed from sheet material that have curved surfaces. The leaves extend around a portion or fully around the diameter of the tubular structure. Some of the adjacent leaves of the tubular are coupled together. The tubular is compressed to a smaller diameter so that it can be inserted through previously deployed tubular assemblies. Once the tubular is properly positioned, it is deployed and coupled or not coupled to a previously deployed tubular assembly. The tubular is useful for all types of wells and boreholes.

  • System for controlling the fill of compressed natural gas cylinders
    Patent number: 5868176
    Abstract: A system for controlling the fill of a receptacle cylinder with compressed natural gas (CNG). The flow of gas into the receptacle cylinder is controlled by a fill controller with software configured to calculate the mass of gas to be added to the cylinder as a function of the pressure and temperature in the cylinder during the fill process and to open and close a flow valve in accordance with such calculation.
