  • Clay/polymer blend as high pH or ionic liquid barrier
    Patent number: 9403974
    Abstract: A composition capable of increased impermeability against the passage of ionic liquids therethrough can include a clay mixed with an anionic and cationic polymer. Such compositions can be provided in geosynthetic liners to provide a hydraulic barrier in aggressive leachate environments.
    Type: Grant

  • Radio frequency power measurement
    Publication number: 20050174101
    Abstract: An unknown RF power is converted to a voltage by a detector (11). The voltage is converted to a number by a digitiser (12). A separate and fixed RF power reference (14) drives a second detector (15), whose voltage output is also converted to a number by the digitiser (12). The RF detectors are thermally coupled. Temperature variations in the RF power to voltage characteristic of the detector (11) are corrected by measuring the RF power reference (14) via the detector (15).
