A mixing chamber in which a first liquid comes into contact with a second liquid, and a gas injection device designed to inject a gas into the mixing chamber, wherein the gas injection device includes: a gas source to provide the gas at a predetermined pressure, and a metering unit to limit the gas provided by the gas source to a predetermined flow rate, wherein the metering unit is in contact with the mixing chamber on a gas outlet side of the metering unit, wherein the gas outlet side of the metering unit includes an elongated gap, wherein the gas passes out of the metering unit into the mixing chamber via the elongated gap, and wherein the gas passes out of the metering unit into the mixing chamber.

Disclosed is a device for contactlessly mixing fluid present on the upper surface of the slide, where the device comprises a first nozzle array and a second nozzle array, the first nozzle array adapted to impart a bulk fluid flow to the fluid present on the upper surface of the slide, and the second nozzle array adapted to impart at least a first regional fluid flow to at least a portion of the fluid present on the upper surface of the slide

A diagnostic system for determining the presence of a target in a sample liquid that includes a diagnostic reader and a microfluidic strip having a microfluidic channel network therein. An actuator within the reader modifies the pressure of a gas in gaseous communication with a liquid-gas interface of a sample liquid within the microfluidic channel network to move and/or mix the sample liquid. The pressure modifications may be continuous and/or oscillatory.

A shotcrete nozzle assembly comprising: a tubular body including a body sidewall defining a central passageway extending along a central longitudinal passageway axis, and water dispensing bores extending through the body sidewall and including: first and second sets of water dispensing bores positioned such that outlet openings thereof defined in an inner face of the body sidewall are disposed in a respective one of longitudinally spaced-apart first and second transversal planes extending perpendicularly to the passageway axis, at least some of the water dispensing bores being oriented such that the central bore axes thereof extend in a non-radial direction relative to the passageway axis, and such that an orthogonal projection of the central bore axes of the first and second sets of water dispensing bores onto one of the transversal planes forms first and second projected central bore axes which intersect each other at a first non-zero angle.

The invention relates to a mixing conveyor for an injection molding system, in particular a thixomolding injection molding system, or the like for conveying a granule-powder mixture, comprising the following: a mixing container (10), with at least one feed (11, 13) for granular material (12) and/or powdery material (14); and at least one mixing device (13a, 13b, 13c, 13d) which is designed to mix the granular material (12) and the powdery material (14) to form a granule-powder mixture; and a mixing container outlet (15), which can be arranged in particular in the vicinity of a melting area (51) of the injection molding system (50) or the like, and is designed to discharge the granule-powder mixture or to feed it to the injection molding system (50) or the like for at least partial melting.

Disclosed herein are powder mixing apparatuses and methods that utilize the deagglomerizing and mixing effects of an air flow that impacts a flowing powder. The resulting powder can have smaller particle sizes and/or exhibit a more homogenous mixture than the premixed powder.

There is provided a kitchen appliance apparatus for using air in the kitchen, comprising a housing, wherein in the housing a pump system is provided which pump system comprises, a primary port (106), a secondary port (107), a single direction air pump (101) having an inlet (102) and an outlet (103); wherein the pump system is operational in a first pump mode in which air can be sucked in via the primary port; the pump system is operational in a second pump mode in which air can be blown out via the primary port; and is operational in a third pump mode in which the pump system is alternatingly sucking in and blowing air via the primary port.

Some variations provide a system for producing a functionalized powder, comprising: an agitated pressure vessel; first particles and second particles contained within the agitated pressure vessel; a fluid contained within the agitated pressure vessel; an exhaust line for releasing the fluid from the agitated pressure vessel; and a means for recovering a functionalized powder containing the second particles disposed onto surfaces of the first particles. A preferred fluid is carbon dioxide in liquefied or supercritical form. The carbon dioxide may be initially loaded into the pressure vessel as solid carbon dioxide. The pressure vessel may be batch or continuous and is operated under reaction conditions to functionalize the first particles with the second particles, thereby producing a functionalized powder, such as nanofunctionalized metal particles in which nanoparticles act as grain refiners for a component ultimately produced from the nanofunctionalized metal particles. Methods for making the functionalized powder are also disclosed.

A stirring device has a storage tank and a stirring member that stirs an inside of the storage tank, and the stirring member has a humidified air release port through which humidified air, which is air humidified, is released into the storage tank.
