Provided is a slurry treatment apparatus includes: a treatment tank for performing any treatment of a solid-liquid reaction, a solid-gas reaction, a gas-liquid reaction, and solid-liquid separation on a slurry containing a metal or a metal compound; a first pipe; a second pipe; and a pump, in which one end of the first pipe has a suction opening for sucking the slurry from the treatment tank, the other end of the first pipe is connected to a suction port of the pump, one end of the second pipe is linked to a discharge port of the pump, the other end of the second pipe is connected to a microbubble generator, and the microbubble generator includes a throttle that throttles a flow of the slurry and a gas supply tube for supplying gas to the throttle, and supplies microbubbles to the slurry in the treatment tank.

Apparatus and methods for mixing and dispersing a dispersed phase in a medium comprise a rotating surface for receiving the medium and an atomizing apparatus positioned at the rotating surface for depositing aerosolized constituents of the dispersed phase into the medium. The medium is made receptive and the dispersed phase is aerosolized. Constituents of the aerosolized dispersed phase are deposited into the receptive medium to form a compound or composite. The medium may be deposited onto a rotating disk, and the dispersed phase may be sprayed onto the disk. A thin film can be generated on the disk to transfer, distribute, and disperse the dispersed phase. Liquid ligaments formed at the edge of the rotating disk further transfer, distribute, and disperse the dispersed phase into the medium. Ligaments may be broken into aerosols or deformed by attenuation/drawing to further promote transfer, distribution, and dispersion. A bulk composite/compound may be collected.

A method for the manufacture of foamed plaster utilizing a mixture of powdered casting plaster, powdered limestone and hemp fibre. The mixture is fed into a Venturi apparatus (40) under the influence of gravity. Compressed air may be supplied to the Venturi apparatus (40) through an inlet pipe (41) causing air and solid particles to be sucked into the Venturi apparatus (40). The elongated tube is provided with an inlet nozzle arranged to receive a mixture of water mixed with detergent agents. Further, the tube (50) is provided with an inlet nozzle (56) arranged to receive compressed air such that the elongated tube (50) delivers the mixture to a mixing and spray head (60) so as to feed the resulting mixture to a moulding means.

An apparatus comprises a separator, a compressor, a mixer and a pump. The separator operates on an input gas mixture comprising carbon dioxide gas and one or more other gases, providing a separated carbon dioxide gas output. A compressor compresses the separated carbon dioxide gas output, providing a second output comprising at least one of gaseous carbon dioxide and liquid carbon dioxide. A mixer mixes the second output with liquid water under pressure to provide a third output comprising: at least one of liquid carbon dioxide and gaseous carbon dioxide; and water with dissolved carbon dioxide. A pump pumps the third output into an underground structure such that components of the third output react with available rock surfaces to form stable carbonates.

An apparatus for mixing fluids within a pipe is provided. In one embodiment, the apparatus includes a fluid mixing device with a pipe having a pipe wall and an axial bore for conveying fluids through the pipe. The fluid mixing device also includes a sleeve disposed about the pipe and a cavity provided between an exterior surface of the pipe and an interior surface of the sleeve. The cavity and the axial bore of the pipe are in fluid communication with one another via an opening through the pipe wall. Additional systems, devices, and methods are also disclosed.

Disclosed herein are inversion systems and methods of diluting w/o lattices including about 10 wt % to 80 wt % of a water soluble polymer. Using the inversion systems and methods described herein, dilution of w/o lattices is carried out in a single step to form dilute lattices having 10,000 ppm or less polymer; the dilute lattices form polymer solutions with no further addition of mixing force or water. The solution viscosities of the polymer solutions obtained using the systems and methods of the invention are at least about 80% of solution viscosity expected in the absence of shear.

Disclosed herein are instruments and methods for performing both sample homogenization and sample clarification by centrifugation with a single instrument without transferring the sample to a new sample container and without removing or repositioning the sample container within the instrument. In some embodiments, the instrument may automatically perform centrifugation after homogenization. In other embodiments, the instrument may perform both homogenization and centrifugation simultaneously.

Disclosed are improved methods for producing solid powdered theacrine compositions that are virtually flavorless and improved theacrine compositions.

A stirring device for stirring a biphasic fluid has a stirring shaft that can be mounted with a mounting end into a stirring drive. The stirring device also has a first paddle that is arranged in a rotationally fixed manner at or near a stirring end of the stirring shaft that is opposite to the mounting end, and further has a second paddle that is arranged in a rotationally fixed manner at the stirring shaft in between the mounting end and the first paddle. The second paddle is mounted with respect to the stirring shaft in such a manner that it can be displaced in an axial direction along the stirring shaft, which allows for a change of an axial distance between the second paddle and the mounting end of the stirring shaft.
