  • Patent number: 7470094
    Abstract: A geocomposite for use in a landfill, including a geonet and a geotextile bonded to at least one side of the geonet. The geonet includes a first plurality of substantially parallel strands, and a second plurality of substantially parallel strands disposed on top of the first plurality of strands, the second plurality of strands being at an angle relative to the first plurality of strands. The first and second plurality of strands are substantially incompressible and secured to one another at crossover locations, and are substantially round in cross-section.
    Type: Grant
    Filed: November 10, 2005
    Date of Patent: December 30, 2008
    Assignee: GSE Lining Technology, Inc.

  • Patent number: 6566892
    Abstract: A portable fuel analyzer includes a sensor, a processor and a display. The portable analyzer receives a fuel sample and the display identifies whether the vehicle fuel is tainted. The portable fuel analyzer is linked to an evaluation unit to determine a frequency measurement based upon signals from the sensor in the portable fuel analyzer. The evaluation unit provides a method of comparing the frequency from the vehicle fuel sensor with the frequency from the portable fuel analyzer. If the green LED is illuminated and the portable fuel analyzer indicates a different frequency than the vehicle fuel sensor, the vehicle fuel sensor is defective and should be replaced; If the green LED is illuminated and the portable fuel analyzer indicates the same frequency as the vehicle fuel sensor, a vehicle component other than the vehicle sensor is faulty; and, if the red LED is illuminated, the mixed fuel sample is tainted and a determination about the vehicle fuel sensor cannot be determined.
