Abstract: Liquid is supplied within a substantially vertical mixing chamber in a substantially tangential manner from a chamber top section, such that the liquid is deflected for rotatory motion against a chamber wall while advancing, in response to a pressure difference, downwards in the direction of a chamber longitudinal axis. Pulverous material is supplied by compressed air into the chamber (3) from the top section and into an air core (A) established by the liquid in rotatory motion, such that the pulverous material containing little air, and by being heavier than the air contained in the pulverous material and/or used for carrying the same, is driven in response to a centrifugal force into the liquid in rotatory motion, and the air separates towards the eddy center, and that the liquid containing pulverous material and the air supplied into the chamber, are discharged through an open bottom section of the chamber (3).

Abstract: The hot coffee mixing device comprises one embodiment having a hollow cylindrical tube with a bottom end with liquid outlet(s) thereon which rests upon the bottom surface of the carafe when in use. The top end of the device has a liquid inlet which is located in close proximity to the center of the carafe and the lid of the carafe. The liquid inlet and outlet(s) are connected by a channel. Another embodiment of the hot coffee mixing device is suspended from the lid of the coffee carafe and comprises a hollow cylindrical tube having a bottom end with liquid outlet(s) thereon, not resting upon the bottom of the carafe, and the top end of the device has a liquid inlet and means for supporting the device on the lid of the carafe. In yet another embodiment, the hot coffee mixing device may be either free standing on the bottom of the coffee carafe or suspended from the lid of the coffee carafe or the coffee carafe itself when in use.

Abstract: An eductor mixing device (10) has a main body or housing (28) of a generally cylindrical shape and an inner tube (42) for one component to be mixed with a liquid is mounted in main body (28) with a vortex chamber (56) formed in an annulus between the main body (28) and the inlet flow tube (42). Pressurized liquid enters the vortex chamber through a generally rectangular entrance opening (36) along an arcuate surface (42) which smoothly merges with the cylindrical surface (30) of the main body or housing (28). A liquid in a swirling motion moves in a descending helical path about inner tube (42) and passes through a gap G between coaxial frusto-conical surfaces (55) and (68) of the converging inner nozzle (52) of the inner tube (42) and an outer coaxial liquid nozzle (60) of diffuser ring (58) .

Abstract: A direct injection contacting apparatus for contacting a first fluid with a second fluid which facilitates heat and mass transfer operations.

Abstract: In one embodiment, a mixing device includes a nozzle that is disposed tangent to a wall of a chamber. Gas flowing from the nozzle rotates in the chamber forming a vortex. Another gas may be flown near a middle portion of the chamber, thereby uniformly mixing the two gases. In another embodiment, an evaporation and mixing device includes a nozzle configured to impart rotation to a gas flowing into a chamber. An injector flows a liquid material near a middle portion of the chamber, thereby mixing the gas and the liquid material. A heater may be employed to help evaporate the liquid material.

Abstract: Apparatus for mixing aqueous foam with a slurry of gypsum and water. A cylindrical housing includes, in its upper end, an inlet for a slurry and a helical diverter for directing the slurry in a downward spiral flow path. An inlet for aqueous foam in located in said diverter and directs the foam into the incoming slurry. An annular flow restrictor is located in the lower end of the housing. Turbulence resulting from diversion of the incoming slurry from linear flow to a downward spiral flow path and from changes in spin diameter and speed through the flow restrictor uniformly mix foam with the slurry.

Abstract: A static mixer for a viscous liquid for use in a chemical mechanical polishing process is provided. The static mixer is constructed of an elongated cylindrical tank, an elongated cylindrical mixing sleeve having a multiplicity of mixing apertures therethrough situated inside the tank, a plurality of curvilinear feed tubes situated at a top of the tank cavity for feeding a mixture of a viscous liquid and a solvent into the tank cavity, a spiral plate mounted on the interior surface of the tank wall extending continuously from a top wall to a bottom wall of the tank cavity, and an outlet tube that is situated at the bottom of the tank cavity inside the mixing sleeve for outputting a mixture.

Abstract: A multiphase mixing apparatus using acoustic resonance. The apparatus can induce a pressure difference between fluids to be mixed so that a resonance and an acoustic energy are generated, thereby shattering the fluids and effectively mixing them. The shattered gas fluid penetrating into the liquid fluid goes along a swirl flow so that the gas fluid stays in the liquid fluid for a relatively long time. In addition, the acoustic energy perturbs the fluids, a mass transfer resistance decreases.
