An apparatus for mass producing monodisperse microbubbles includes a microfluidic flow focusing device, which includes a dispersed phase fluid supply channel having an outlet that discharges into a flow focusing junction, a continuous phase fluid supply channel having an outlet that discharges into the flow focusing junction, and a bubble formation channel having an inlet disposed at the flow focusing junction. The configuration of the flow focusing junction is such that, in operation, a flow of dispersed phase fluid discharging from the outlet of the dispersed phase fluid supply channel is engageable in co-flow by a focusing flow of continuous phase fluid discharging from the outlet of the at least one continuous phase fluid supply channel under formation of a gradually thinning jet of dispersed phase fluid that extends into the inlet of the bubble formation channel.

A method for causing exhaust gas flow to flow at least 270 degrees in a first direction about a perforated tube using a baffle plate having a main body with a plurality of flow-through openings and a plurality of louvers positioned adjacent to the flow-through openings. The method includes deflecting a first portion of the exhaust gas flow with the main body of the baffle plate. The method also includes allowing a second portion of the exhaust gas flow to flow through the flow-through openings of the baffle plate. The method also deflects the second portion of the exhaust gas flow at a downstream side of the main body with the louvers hereby causing the second portion of the exhaust gas flow to flow in the first direction about the perforated tube.

A fuel injection system may comprise a mixer and a fuel injector disposed within the mixer. The mixer may comprise an outer housing with an exit port and a bluff body extending across the exit port of the outer housing. A flared surface of the mixer may match a contour of the bluff body.

The present invention provides a gas generator and comprises an electrolytic cell, a condensate filter device, and an atomizing device. The electrolytic cell is for electrolyzing electrolyzed water to generate a gas with hydrogen. The condensate filter device includes a gas pathway, a filter, and an isolated component. The isolated component is used for limiting the movement of the filter inside the gas pathway. The gas generated from the electrolytic cell is condensed and filtered through the filter for generating a filtered gas with hydrogen. The atomizing device is used for generating an atomizing gas to be mixed with the filtered gas to generate a healthy gas. The present invention uses the condensate filter device to filter out the electrolyte from the filtered gas with hydrogen to be mixed with the atomizing gas for generating the healthy gas.

A device for generating bubbles, comprising a porous material having at least one hydrophilic surface (1), arranged such that a liquid (7) in which the bubbles (6) are intended to be formed may contact the hydrophilic surface (1) and at least one hydrophobic surface (2), arranged such that a gas (5) used to generate the bubbles (6) may flow past the hydrophobic surface (2) before it flows past the hydrophilic surface (1). The device may be used for creating fine bubbles in numerous applications, such as wastewater treatment, plant cultivation, aquafarming, aeration systems, bioreactors, fermeters, oil extraction or fuel cells.

The present invention relates to aqueous compositions for forming a foam, comprising a surfactant and a particulate inorganic material, and optionally one or more polymers, such as soil conditioning polymers, and/or viscosity increasing polymers. The present invention further relates to the use and application of said aqueous compositions.

The present invention is related to a system and method for controlled manufacturing of mono-disperse microbubbles. According to the invention, the mono-disperse nature of the collection of generated microbubbles can be improved by releasing the pressurized gaseous medium used in the system using release valve units. This further allows the system to be embodied as a portable system. In turn, the operator of an ultrasound imaging apparatus may use the system according to the invention to generate microbubbles on a patient-by-patient basis.

Disclosed is a process in which a viscous initial product having both a temperature of between 5° C. and 70° C. and a viscosity greater than 100 mPa.Math.s is provided, —by way of a pump provided upstream of at least one aerator, the viscous initial product is transferred as it is to the at least one aerator in which the viscous initial product is mixed with a gas, injected into the aerator, so as to obtain a liquid foam continuously exiting the aerator, and—the liquid foam continuously exiting the at least one aerator is continuously pushed into the inlet of a treatment device which continuously divides and then dries this liquid foam so as to obtain a powdered porous product which has a solids content greater than 90%.

The present invention describes methods and devices in which concentrated beverage products, each packaged in a pressurized container, can be combined with liquids and/or other ingredients to produce one or more servings of a beverage. These products provide users with a convenient way to prepare both alcoholic and non-alcoholic beverages (including carbonated beverages) in various serving sizes and quantities by combining the pressurized beverage concentrate with (possibly carbonated) liquids and other ingredients.

The present invention relates to a device and method for making sclerosing foam, which is useful in the treatment of varicose veins and other venous conditions. The device comprises a continuous pathway that is at least partly formed of flexible or compressible material and that comprises a foam generating structure within the continuous pathway; the foam generating structure being formed of two or more elements, wherein each element defines at least one passageway of cross sectional area 1 μm2 to 10 mm2 and said two or more elements being arranged in series; a port which allows introduction of material into or extraction of material out of the continuous pathway; and a liquid pathway that is at least partly formed of flexible or compressible material and is arranged to deliver liquid into the foam generating structure between a first and second element of the foam generating structure.
