  • Patent number: 11123587
    Abstract: A system for mixing fire-suppressant gel with water on board an aircraft includes a gel reservoir mounted in the aircraft, a pump for injecting gel into a flow of water into an aircraft-mounted payload tank, and a control system for controlling gel-water mix ratios. The control system monitors water volume flowing into the water tank, and regulates the gel pump to inject gel in appropriate amounts to produce gel-water emulsions having precise gel-water ratios. Settings for the control system are set by the pilot before water flow water is initiated. Once the aircraft is in flight, the gel-water mixing process is automatically controlled through a trigger on the pilot's control stick. The aircraft may be a helicopter or fixed-wing aircraft adapted to load water from a lake or other source while in flight, or a fixed-wing aircraft adapted to load water on land from a pressurized water source.

    Abstract: The invention relates to a method and apparatus for capturing a stir bar in a container. A stir bar may be placed in a container and subjected to a changing magnetic field that causes the stir bar to rotate inside the container. A retaining band or sleeve having metallic or magnetic inserts or materials is placed around a portion of the container so that it is positioned near where the stir bar may be located or might slide past as the contents of the container are poured out of the container. Magnetic attraction between the retaining band or sleeve and the stir bar helps prevent the stir bar from inadvertently being poured out of the container.

  • Publication number: 20110303088
    Abstract: Provided is a method for contacting a gas with a liquid in a rotating packed bed. The method comprises providing a rotating packed bed comprising two sets of rotatable packing rings disposed within a chamber and defining an interior region. The rotating packed bed also comprises at least one liquid distributor with an inlet for accepting a liquid, the inlet in communication with an exit port for infusing the liquid into the interior region. The liquid distributor also comprises at least one gas outlet for accepting gas which has passed through the packed bed and for removing the gas from the interior region. The two sets of rotatable packing rings are caused to rotate. Liquid is infused into the interior region by way of the liquid inlet, and gas is injected through at least one gas inlet into the interior region, with the liquid and gas passing through each of the packing rings in countercurrent flow.

  • Patent number: 8062610
    Abstract: For analysis of small quatities of target analytes in an environment, the gas flow can be delivered to a suitably fast analyzer and their concentration determined in a time period whose duration is dependent on the analyte, its concentration and the phase separation properties. A device having a sorbent bed that is essentially concentric with a passage way containing thermal fluid is used to concentrate the target analyte.

  • Patent number: 7785743
    Abstract: The present invention discloses methods and devices for humidifying the proton exchange membranes of fuel cells with water obtained from the exhaust of the fuel cells. Humidifying methods include the following steps: cooling the hot and humid exhaust of the fuel cell to condense the water in the exhaust with the intake gas for the fuel cell; separating the water from the rest of the exhaust, and, delivering the water to the intake gas of the fuel cell. Humidifying devices include an outer shell containing a rotating inner shell. The inside of the inner shell forms a chamber where the exhaust is collected and cooled, and water is condensed and separated by the rotation of the inner shell. Openings on the inner shell allow the condensed water to pass through to one or more chambers containing the intake gas. The chambers are formed by the inside of the outer shell and the outside of the inner shell.
