An ultrasonic humidifier includes a tank having a water level and a floater having a tubular structure with a bottom rim and a top rim. The tubular structure has a frusto-conical shape and is vertically and co-axially disposed within the floater. The tubular structure having a widest diameter end disposed on the bottom rim and a narrower diameter end disposed at the top rim. This humidifier also has an air-supply arrangement that eliminates water damage to the fan during spillage.

A humidification device (1) is shown wherein water is nebulized by a vibrating mesh with very small holes. The mesh is part of a reservoir which is fed by a valve arrangement which allows to direct water from a conduit over several water lines within the device either back to the conduit or into the reservoir. The device and a system with such devices allow to humidify and/or cool compartments such as rooms with a very fine mist of water which is hardly visually detectable. The system and device is adapted to be part of a permanent installation with low maintenance.

An eductor suitable for use in an assembly for preparing a liquid product comprises a housing having a substantially cylindrical wall. The eductor comprises an injector valve which is displaceably arranged within the cylindrical wall from first position to a second position longitudinally spaced from the first position, and vice versa. On its outer surface the injector valve comprises two annular protrusions which are spaced from each other, each of the annular protrusions engaging the inner surface of the cylindrical wall for forming a seal therewith, said annular protrusions together with the inner surface of the cylindrical wall forming an annular chamber, said protrusions being arranged for isolating the annular chamber from fluid communication with any environment outside the annular protrusions when said injector valve is positioned in the first position or the second position or any position in between.

Nozzle Assemblies and methods of use for producing a liquid jet are disclosed that may be permit adjustable time delays between mixing of fluids and observation of reactions. An example nozzle assembly includes: a housing having an inlet and an outlet and a first channel defined therebetween, where the housing includes a gas focusing aperture defining the housing outlet; an intermediate tube disposed within the first channel of the housing, where the intermediate tube has an inlet and an outlet and defines a second channel therebetween; and a central tube disposed within the second channel of the intermediate tube, where the central tube has an inlet and an outlet and defines a third channel therebetween, where the central tube outlet is longitudinally spaced apart from the intermediate tube outlet such that the intermediate tube outlet is disposed between the central tube outlet and the gas focusing aperture's inlet.

an apparatus, system, and method for contacting blood with ozone to kill microorganisms in the blood are described. The method involves injecting microbubbles of ozone containing gas into a flow of blood, preferably at a temperature of less than 12° C. The apparatus includes a blood flow conduit including a blood ozone contacting portion including a porous ozone injector. Figure to be published with the abstract:

A device aerates a drinkable liquid inside a handheld container. An aerator is detachably mounted on the container in a mounted position. The aerator has an aerator portion that extends into the liquid and that is held adjacent an interior surface of a side wall of the container in the mounted position. The aerator portion has a multitude of turbulence-inducing agitating elements, such as pores, through which the liquid in the container flows to, and impacts against, the interior surface of the side wall of the container, and mixes with ambient air in the container, when the container is manually swirled to aerate the liquid.

An apparatus (12) for treating water, in particular for removing surfactants from waste water, includes a vessel (14), defining an inlet (16) for receiving waste water containing air bubbles, and an outlet (20) for the exit of water, following treatment. Inside the vessel there is at least one tubular member (50) having a lower open end (52) into which the flow of waste water from the inlet may be directed in use. The tubular member (50) extends from the inlet towards a top of the vessel where an upper exit (54) from the tubular member is defined. In use, most un-aerated water entering the vessel through the inlet can exit the tubular member at the lower open end. Foam formed in the water by the air bubbles may travel up the tubular member to the upper exit, which is preferably located above the water level (60) in the vessel.

The invention relates to a diffusor for adding of gases into water, said diffusor comprising a perforated tube (1) and at least one supply tube (2), said the at least one supply tube (2) is at one end coupled to a source for supplying gas and at the other end in fluid communication with the perforated tube (1), the gas is supplied to the perforated tube (1) through at least one inner supply tube (4; 5; 15) extending from the supply tube (2) to the perforated tube (1). The invention is distinctive in that at the least one inner supply tube (4; 5; 15) is a non-perforating tube and has at least one outlet (4a, 5a, 15a) situated at a free end of the at least one inner supply tube (4, 5, 15), said gas is adapted to be distributed into the perforated tube (1) through the at least one outlet (4a, 5a, 15a).

A domestic carbonation appliance. The appliance has a replaceable CO2 cylinder, and accepts a refillable bottle. The appliance has a processor for controlling the functions of the device. The appliance comprises: a chassis having a filling chamber; a fill head in the filling chamber, the fill head being attachable to a source of pressurised carbon dioxide gas; the filling chamber having a safety door and locking device; the device having a sensor for detecting a door state and transmitting door state information to the processor; and the processor being adapted to initiate a carbonation process in response to the door state information.

A system for mixing drilling fluids that includes a fluid supply tank for supplying an unmixed drilling fluid, a mixing reactor fluidly connected to the fluid supply tank, the mixing reactor including an intake and an outlet; a mixing chamber disposed between the intake and the outlet, an inlet for injecting a compressible driving fluid into the mixing chamber and an inlet for injecting an aerating gas into the mixing chamber is disclosed.
