A method and apparatus for mixing fluids, such as beverage syrup and water, uses countercurrent injection to improve blending of the fluids. A mixing chamber has a first inlet through which a first fluid is fed to the mixing chamber, and a second inlet through which a countercurrent injection nozzle extends and is operative to inject a second fluid into a stream of the first fluid. The countercurrent injection nozzle is equipped with a check valve to control the flow of fluid into the mixing chamber. The mixing chamber may include additional inlets that may be fitted with countercurrent injection nozzles to permit the countercurrent injection of other fluid, such as flavorings, into the stream of the first fluid.

A processing system for depositing a plurality of source materials on a substrate, includes a first thermal evaporation source that can evaporate a first source material to produce a first vapor, a second thermal evaporation source that can evaporate a second source material to produce a second vapor, a vapor mixing chamber that allows the first vapor and the second vapor to be mixed to produce a mixed vapor, and conduits that can separately transport the first vapor and the second vapor to the vapor mixing chamber. The mixed vapor can be directed toward a substrate to deposit a mixture of the first source material and the second source material on the substrate. The processing system can also include vapor filters configured to regulate flows of the first vapor and the second vapor, and a mixed vapor filter to regulate flow of the mixed vapor.

A method and apparatus for mixing a first stream of gas with a second stream of gas is provided. The method includes introducing a first stream of gas into a first stream manifold and directing the first stream from the first stream manifold into a mixing chamber via a plurality of first stream passages flow coupled to the mixing chamber. A second stream of gas is directed into the mixing chamber via at least one second stream passage flow coupled to a first end of the mixing chamber. A combined stream is formed from the first and second streams, gradually converged, and discharged from the mixing chamber through a mixing chamber exit port.

Methods and apparatus of forming hydrogel systems in situ are provided using a delivery system configured to deliver two or more fluent prepolymer solutions without premature crosslinking. The delivery system comprises separate first and second lumens coupling first and second inlet ports and first and second outlet ports, respectively, and may include a balloon, flexible distal region, mixing chamber or steerable distal end. Multi-component hydrogel systems suitable for use with the inventive methods and apparatus are also described.

A compact portable dual mode hemodialysis machine system is provided. The system includes a sorbent dialysis module with a sorbent cartridge that purifies a dialysate fluid that flows therethrough, where the sorbent dialysis module returns the purified dialysate fluid from the sorbent cartridge to an inlet of a dialyzer. The system also includes a single-pass dialysis module with an acetate pump, a bicarbonate pump and a mixing chamber, where the acetate and bicarbonate pumps flow acetate and bicarbonate mixtures, respectively, into the mixing chamber. The single-pass dialysis module receives a desired amount of water from a reverse osmosis device, the single-pass dialysis module operated to direct used dialysate from the dialyzer to a drain. The machine system can be operated to replace the sorbent cartridge with the single-pass dialysis module to switch the operation of the dual mode hemodialysis machine system from a sorbent dialysis mode to a single-pass dialysis mode

The catalytic reactor with downward flow comprises a chamber (1) containing at least two solid catalyst beds (2; 11) separated by an intermediate zone comprising an essentially horizontal collecting plate (5) communicating with a vertical collecting pipe (7) for receiving fluids collected by the collecting plate, with a means for injecting a quenching fluid (8) emptying into the collecting pipe. An annular mixing chamber (9) is located below the collecting plate (5). A predistribution plate (11) is arranged below the chamber (9).The injection means (8) comprises a tubular portion that empties into the collecting pipe (7) in such a way as to inject quenching fluid in a direction forming an angle θ between 45° and 135° with the direction D from the axis of the mixing chamber measured at its input end.

A device generates a gas-enriched physiologic fluid and combines it with a bodily fluid to create a gas-enriched bodily fluid. The device may take the form of a disposable cartridge. The cartridge may include a fluid supply chamber for delivering physiologic fluid under pressure to an atomizer. The atomizer delivers fluid droplets into a gas-pressurized atomization chamber to enrich the physiologic fluid with the gas. The gas-enriched physiologic fluid is delivered to a mixing chamber in the cartridge where the gas-enriched physiologic fluid is mixed with a bodily fluid, such as blood, to create a gas-enriched bodily fluid.

Implantable devices for controlled delivery of a drug are provided which include a substrate; at least two reservoirs in the substrate, each reservoir having an opening; at least one therapeutic agent in each of the reservoirs; a reservoir cap sealing each opening; a mechanical rupturing mechanism which moves into contact with and ruptures the reservoir cap to permit release the therapeutic agent from the reservoir through the opening; and a mixing chamber adjacent the reservoirs, wherein upon release of the therapeutic agent from at least one of the reservoirs, the therapeutic agent is combined with a carrier fluid in the mixing chamber and then transported to a delivery site in a human or animal.

A membrane module (5) including a plurality of porous membranes (6) extending in an array and mounted, at least at one end, in a header (8). The header (8) has a number of distribution apertures (11) for distributing a fluid into the module (5) and along a surface or surfaces of the membranes (6). An elongate chamber (10) having one open end (13) and another end is in fluid communication with the distribution apertures (11) for distributing the fluid to the distribution apertures (11).

There is provided a lighting device and a method to manufacture such a lighting device. The inventive concept is based on manufacturing a lighting device on an at least partly flexible sheet assembly which is rolled into a tube, such that the light source of the lighting device is arranged within the tube. The flexible sheet assembly is arranged such that the tube provides a light mixing chamber and light exit surface for the lighting device. Thus, the tube shaped lighting device instantly delivers the necessary optical and mechanical properties for easy assembly and the functionality of a light engine.

A method and an arrangement for successively feeding batches into a mixing vessel under partial vacuum for the preparation of bone cement. The arrangement includes an inner container communicating with the atmosphere and with the mixing vessel, which container is so arranged as to enclose a glass ampoule containing a liquid bone cement component and, on the other hand, a device for opening the ampoule so that its contents can be sucked into the mixing vessel under partial vacuum. An outer container encloses the inner container at least partially, and is arranged to communicate with the mixing vessel. The inner container, and the outer container, define a space filled with a proportional quantity of a second bone cement component, which is in powder form. The inner container is capable of displacement relative to the outer container between a first position, in which sections of the inner container prevent communication between the mixing vessel and the atmosphere, and a second position, in which communication between both the mixing vessel and the atmosphere is open, so that the powdered bone cement component can be sucked into the mixing chamber under vacuum. The feeding sequence of the bone cement components is arbitrary. In other embodiments, the inner and outer containers are eliminated, or only the inner container is retained.
