A gas mixer (100), to which a first gas and a second gas are fed, mixes the two fed gases to form a gas mixture. A helical component (2) is arranged in an interior of an outer component (5). A helical mixing cavity (20) is formed between the outer component and the helical component (2). An additional mixing volume (6) is located in the interior of the outer component (5) or in the interior of the helical component (2). One gas is sent through a first feed line (31) to the helical mixing cavity (20), and the other gas is sent through a second feed line (32) to the additional mixing cavity (6). A gas mixture discharge line (40) discharges the produced gas mixture from the helical mixing cavity (20).

A container with two inner chambers (6, 7) running in its longitudinal direction and separated by at least one partition wall. An aerobic adhesive is stored in one inner chamber (6). A hydrophilic, gel-like activator is stored in the other inner chamber (7); a mixing unit can be attached to the front end of the container. The aerobic adhesive is fed to the mixing unit from the first inner chamber (6), and the hydrophilic activator is fed to the mixing unit from the second inner chamber (7), in a specified mixing ratio via a supply device and mixed together there. This mixture is discharged via an outlet opening (13) of the mixing unit.

A method for producing a single-phase phase-stable liquid is provided, in which, in an embodiment: in a first step, a lipophilic liquid is mixed with a hydrophilic liquid, so that a mixture of the liquids is obtained; in a second step, the static pressure of the mixture is brought below the vapor pressure of at least one of the liquids, so that cavitation bubbles occur, for example, as a result of what is known as hard cavitation; and in a third step, the cavitation bubbles are caused to implode, a single-phase phase-stable liquid being obtained.

A portable aerator comprising: a main aeration body; a base portion; an internal cavity; at least one ventilation shaft; a spout portion; an aeration opening; and an aeration inlet. The internal cavity comprises a threaded channel and cavity extends from a base portion opening to a spout portion opening. The internal cavity is configured to pass a liquid, such as wine that enters the internal cavity body at the base opening out through the spout portion opening. The threaded channel is threaded on an interior surface, such that the threaded channel is configured to matingly engage and disengage with a worm of a corkscrew bottle opening device, such as a waiter's wine key, via twisting and untwisting, respectively. The aerator device may have at least one ventilation shaft, an aeration shaft, and/or an extension tube.

A static mixer for liquids or gases includes a housing having a continuous inner surface defining a fluid flow path for liquids or gases, an inlet to the fluid flow path, and an outlet from the fluid flow path, and an insert extending longitudinally through the fluid flow path between the inlet and the outlet. The insert is elastically expansive to exert outwardly directed pressure against the continuous inner surface of the housing. In one embodiment, the insert is hollow and has deflectors dispersed therethroughout and each projecting inwardly into the fluid flow path. In another embodiment, the insert includes a helical deflector extending inwardly into the fluid flow path from the continuous inner surface, and helically about a longitudinal axis of the housing.

A feed mixture distribution device configured to even out a feed of feed mixture in an annular feed mixture feed channel of a burner. The feed mixture distribution device includes a cylindrical member having a cylindrical wall, a first end, a second end, and a longitudinal central axis X. The cylindrical member is at the first end provided with rectangular flat plate means, which extend radially from the cylindrical wall of the cylindrical member and which are arranged symmetrically about the longitudinal central axis X of the cylindrical member. The cylindrical wall of the cylindrical member is between the rectangular flat plate and the second end provided with helical plate means arranged symmetrically about the longitudinal central axis X of the cylindrical member.

A nanobubble-producing apparatus includes a liquid vat provided with a bubble-containing-liquid inlet in an upper part thereof and a bubble-containing-liquid outlet in a bottom part thereof, a microbubble-containing-liquid supply unit to supply microbubble-containing liquid that contains microbubbles to the bubble-containing-liquid inlet of the liquid vat, an ultrasonic collapse unit to radiate ultrasonic waves to the inside of the liquid vat so that an ultrasonic collapse field in which the collapsing of the microbubbles with the ultrasonic waves is concentrated and nanobubbles are generated is formed at a location where the microbubble-containing liquid supplied into the liquid vat through the bubble-containing-liquid inlet flows downward, and a nanobubble-containing-liquid extraction portion where the nanobubble-containing liquid that contains the nanobubbles generated by the ultrasonic collapse unit is taken out of the liquid vat through the bubble-containing-liquid outlet.

By homogeneously mixing a plurality of fluids, when mixing a gas with a liquid, it is possible to mix a large amount of gas into the liquid, so that large bubbles are not generated, and fine bubbles (in some cases, fine bubbles including microbubbles or ultra-fine bubbles) can be mixed into the liquid. A fluid mixing output apparatus of the present disclosure includes a housing and an internal structure accommodated in the housing. The housing is provided with a plurality of fluid supply ports for supplying at least a first fluid and a second fluid and a fluid outlet at its downstream end for outputting a plurality of fluids after mixing the plurality of fluids. The internal structure includes a first portion, a second portion, a third portion, and a fourth portion. The first portion includes a shaft portion and a vane spirally formed to generate a swirling flow in a fluid. The second portion is located downstream from the first portion, and includes a shaft portion and a plurality of protrusions protruding from an outer circumferential surface of the shaft portion. The third portion is located downstream from the second portion, and includes a shaft portion and a vane spirally formed to generate a swirling flow in a fluid. The fourth portion is located downstream from the third portion, and includes a shaft portion and a plurality of protrusions protruding from an outer circumferential surface of the shaft portion. One of the plurality of fluid supply ports of the housing is formed in a portion corresponding to the vane of the third portion, and the second fluid is supplied to the third portion and supplied to the fourth portion as a swirling flow while being mixed with the first fluid.
