  • Inventor(s):
    Robert L. Irvine, Rajagopalan Venkatadri
    Patent Number:
    US 5342765 B2
    Description:

    Disclosed is a method of producing an extracellular product from an aerobic microorganism. The microorganism is grown in an aqueous medium on one side of an oxygen-permeable surface while the opposite side of the surface is contacted with oxygen. The extracellular product is then harvested from the aqueous medium. The method is particularly useful in producing lignin peroxidase from the white rot fungus Phanerochaete chrysosporium.

    Arthur H. Hale, Peringandoor R. Hariharan, Sanjit Roy
    Patent Number:
    US 5637795 B2
    Description:

    A novel process and apparatus have been contrived for the study of the bit/stabilizer balling phenomenon in the laboratory. The device permits a standard testing procedure using a specially designed bob simulating the drill bit for comparing degrees of balling for different rock formations under different drilling conditions involving variable and controlled parameters like weight-on-bit, revolutions-per-minute (rpm), drilling fluids, etc.

    Ashley P. Thrall, Angelene J. Dascanio, Chad P. Quaglia
    Patent Number:
    US 9,334,645 B2
    Description:

    A shelter has a packaged configuration and a deployed configuration. The shelter has four panels, each with four edges and two faces. The first and fourth panels have a rectangular shape, and the second and third panels have a quadrangle shape. The relationship of panel edge lengths and angles of the quadrangle shelter panels create a sturdy enclosure that is easy to erect, manipulate, and reconfigure. Furthermore, the shelter may be erected by rotating the panels into place via pivotal conne…

    Patent Number:
    US 8748331 B2
    Description:

    A method of manufacturing a remediation material uses a biogenic material as a substrate and involves preparing the surface of the substrate to enable a chemical reaction, and performing template-driven surface derivatization on the substrate to provide a net positive charge on the substrate. The remediation material may be placed into contact with surface water, ground water, soil, or sediment by at least one of a permeable reactive barrier, direct well injection, or direct introduction of t…
