  • Patent number: 6180003
    Abstract: An apparatus for storing and disinfecting a fluid includes a container (12) and a cap member (16) for containing the fluid and a cap member (16). The container (12) defines an opening (14) through which the fluid is dispensed therein and is removed therefrom and has at least two electrical contacts which mate with at least two electrical contacts in the cap member. The cap member (16) removably seals the opening of the container (12). An ultraviolet source (24) is mounted to at least one of the container (12) and the cap member (16). The ultraviolet source (24) emits ultraviolet radiation to disinfect the fluid contained in the container (12). A power source is electrically coupled to the at least two electrical contacts of the container (12).

  • Patent number: 5948694
    Abstract: A molecular detection apparatus comprises a molecular receptor (20), a detection element (22) responsive to the molecular receptor (20), and a substrate (24) which supports the detection element (22). The molecular detection apparatus further includes a grasping member (26) and an elongated member (30) to couple the grasping member (26) to the substrate (24).

  • Patent number: 5790476
    Abstract: A first system for locating a portion of an underground sewer includes a buoy which is released into the sewer. The buoy is carried to the portion of the sewer by a flow of fluid therein. An electronic tracking system tracks the buoy during its travel through the portion of the sewer to thereby locate the portion of the sewer. A second system includes a plurality of buoys distributed along a tethered line which are released into the sewer. The plurality of buoys are carried to the portion of the sewer by a flow of fluid therein. A location of each of the plurality of buoys within the portion of the sewer is sensed to thereby locate the portion of the sewer. The plurality of buoys are then removed from the sewer by retracting the tethered line.

  • Patent number: 5635074
    Abstract: A plurality of sensors sense a plurality of parameters including flow rate of a slurry being filtered sensed along a filtration medium and differential pressure across the medium which characterize the operation of a cross-flow filtration system having a moving, continuous filter medium. The plurality of sensors produce a plurality of signals representative of the plurality of parameters. A processor processes the plurality of signals to provide at least one control signal. The at least one control signal is applied to the filtration system to control at least one parameter thereof. As a result, a desired operating condition or a desired performance criterion is automatically maintained during operation of the filtration system.
