  • Publication number: 20030190193
    Abstract: A horizontally pivoted structurally rigid buoyant flood gate, in a housing for the gate arranged in front of an opening to a construction, is pivotally floated out of the housing by rising water entering a portal to the housing, and rotates buoyantly upward toward the opening, rising between two side walls longitudinal to the opening and separated from each other by little more than the side-to-side distance of the gate, allowing little water through any gap separating the gate from the side walls, which preferably is sealed by a compression seal, the hydrostatic pressure of water dammed behind the rising gate urging completed closure of the gate through at least the upper half of the closing arc, pressing the gate sealingly against the jambs.

  • Patent number: 6112494
    Abstract: An apparatus for fixating and elevating an interconnected rebar lattice having individual longitudinal and transverse rebar intersections for use as support for poured concrete in highway and other construction. The apparatus including a holding portion having an open ended recess with two opposing walls being generally U-shaped. The recess has a longitudinal axis and is sized and shaped to receive a longitudinal rod. An arc-shaped portion extends laterally outward from each opposing wall and perpendicular to the longitudinal axis of the recess. The arc-shaped portion has a transverse axis and is sized and shaped to receive a longitudinal rod. the arc-shaped portion includes a recess and opposing walls with one wall including a snap-type lock. A locking member has a generally arc-shaped portion and includes a snap-type lock for attaching to the arc-shaped portions and engaging with the snap-type lock of the arc-shaped portions. A leg portion extends downwardly from the holding portion.

  • Patent number: 5785044
    Abstract: A fluid sample receptacle provides a means of assuring uncontaminated, multiple samples of a fluid specimen. An upper or isolated sample chamber and a lower or primary sample chamber provide redundant test samples. A cover or lid with a downwardly extending column includes a stopper with a removable plug attached to automatically seal the lower sample chamber when the cover is sealed across the top of the upper chamber. This feature guarantees that the sample chambers are sealed or isolated simultaneously and that the test samples are therefore identical when taken. Tamper evident seals prove that either sample has not been contaminated. A preferred embodiment provides a bellows assembly to accommodate variations in ambient pressure and to provide a positive means of expelling a precise quantity of fluid from the receptacle for testing.

  • Patent number: 5411065
    Abstract: A method of obtaining aliquots or samples from a liquid specimen collection container and an apparatus which automateally perforths those methods involves transferring a sample of liquid from a sealed non-deformingly expandable container containing gas and the liquid without contaminating the liquid remaining inside the container, and comprises (a) non-deformingly volumetrically expanding the sealed container sufficiently to reduce pressure therein below ambient pressure outside the container, (b) applying heat selectively to a locus on said enlarged container to non-invasively create a hole having a diameter effective to equilibrate the pressure inside the container with said ambient pressure without loss of liquid from the container, and (c) non-deformingly volumetrically reducing the container to expel liquid from the container through the hole.
