The tube bundle includes tubes having an air permeable, non-porous polymer layer with discontinuities. The repair liquid includes a solvent and a curable thermoset material. The curable thermoset material is deposited in the discontinuities of the air permeable, non-porous polymer layer and cured. Also disclosed is a fuel system oxygen removal unit including a tubular bundle formed of tubes having an air permeable, non-porous polymer layer disposed on a microporous support wherein the air permeable, non-porous polymer layer includes discrete segments of a cured thermoset material.

The present invention generally relates to a system and methods for the separation and removal of carbon dioxide from seawater. The system includes an extraction system that collects carbon dioxide from the seawater through a medium, and removes carbon dioxide from the medium; the extraction system comprising a reactor and a membrane. Alternatively, the extraction system includes a reactor, a membrane and a catalyst.

A membrane device is presented that can used for a wide range of applications from once-through filtration, crossflow filtration, molecular separation, gas/liquid absorption or reaction, gas dispersion into liquid, and degassing of liquid. The device comprises a thin flat sheet membrane that allows certain fluid or molecules go through while blocking others. The membrane sheet is fixed on a supporting structure with mini channel on two sides of the membrane for respective feed and sweep flows. The membrane sheet is sealed with gaskets with two cover plates that the membrane sheet can be replaced or cleaned. The cover plate provides connection ports to connect the feed fluid to the feed channels on one membrane surface and to connect the sweep fluid to the sweep channels on the other surface of the membrane.

A gas trap assembly including a base connector housing including an inflow port and an outflow port, a reservoir fluidly connecting the inflow port to the outflow port, and a grooved porous media located within the reservoir. The grooved porous media including a plurality of grooves and composed of a material having a plurality of pores of a selected size. The grooved porous media fluidly divides the reservoir into two portions in such a way that a working fluid flowing from the inflow port to the outflow port must flow through the plurality of grooves and the plurality of pores of the grooved porous media. The plurality of grooves and the plurality of pores are configured to prevent gas from passing through the grooved porous media.

The present invention is directed to an apparatus suitable for separating and collecting gas bubbles entrained in a liquid, wherein the apparatus comprises a housing defining at least one chamber, the chamber having an inlet port and an outlet port; a diverter positioned between the inlet port and the outlet port; and, an elongated exit tube with an intake end and an export end; wherein the intake end of the elongated exit tube is centrally located within the chamber and the export end of the elongated exit tube is connected to the outlet port of the chamber.

A fluid management system for use with an ultrasound probe assembly can include first and second conduits each configured to extend from and be fluidly connected to the ultrasound probe assembly. A fluid directing system can include a circulation pump fluidly connected to both the first and second conduits. A fluid degassing system can be fluidly connected to the first and second conduits. The fluid degassing system can be configured to remove at least some gas from the fluid in the ultrasound probe assembly. A temperature control system can be fluidly connected to the first and second conduits. The temperature control system can be configured to control the temperature of the fluid in the ultrasound probe assembly. A volume adjustment system can be fluidly connected to the first and second conduits. The volume adjustment system can be configured to adjust the volume of the fluid in the ultrasound probe assembly.

A device for preparing a liquid sample for a direct injection of a corresponding gaseous sample to a micro-gas chromatograph includes: a fluid space and a gas space, which spaces are separated by a semipermeable separating layer, the fluid space including a supply line for the liquid sample, and the gas space having an outlet connectable with the gas chromatograph. The fluid space and/or the gas space is associated with at least one heating element. The device absorbs a sample volume of approximately 10 μl to 30 μl. The separating layer has a thickness of 10 μl to 300 μl and pores having a size between 0.05 μl and 5 μl.

A deaerator includes gas nucleation media and a porous barrier. The deaerator may include growth media between the gas nucleation media and the porous barrier. The deaerator may be part of a system for removing gas from a fluid, where the system includes a tank with a fluid inlet and a fluid outlet and having a fluid flow path from the fluid inlet to the fluid outlet, and where the deaerator is in the fluid flow path. A method for removing gas from a fluid includes passing the fluid through the deaerator defining a fluid flow path.

A reserve tank has a container, an outlet component, and an inlet component. The outlet component and the inlet component are mounted on the container. The outlet component has an open end located at a center of the container. The inlet component has a branch portion mounted in the container and an inlet channel in the branch portion. Therefore, when the reserve tank is disposed obliquely, even though the reserve tank is not full of a working liquid and contains some gas, the gas can hardly flow into the open end of the outlet component. In addition, if some gas enters the container through the inlet channel and thus forms bubbles, the bubbles may move upward along part of the branch tunnels extending upward, so the entering bubbles are still far from the open end.

A blood purification device 1 is provided with: a blood circuit 2 for extracorporeally circulating blood of a patient; a blood purifier 3 provided in the blood circuit 2; a gas-liquid separator 24 which is provided in the blood circuit 2 and located on the downward side of the blood purifier 3 in the direction of blood flow, and separates air bubbles contained in blood flowing thereinto; and a liquid surface adjustment unit 6 capable of adjusting the liquid level in the gas-liquid separator 24. The liquid surface adjustment unit 6 performs control such that the liquid level during priming is higher than the liquid level during treatment.
