Abstract: A device for mixing powder of the like with a liquid, the device including both a dispersion tube having its bottom portion open and designed to be in the liquid and having a delivery orifice for powder or the like in its top portion, and a mixer located in the dispersion tube and including a first rotary stirrer disposed in the vicinity of the bottom end of the dispersion tube and suitable for creating a first downward stream in the dispersion tube. The mixer further includes a second rotary stirrer disposed between the delivery orifice for powder or the like and the first rotary stirrer, and suitable for creating a second downward stream in the dispersion tube.

Abstract: An immersion cooler comprising an agitator motor having a drive shaft, an evaporator located in a tank and surrounding the drive shaft, and an agitator coupled to the drive shaft. The agitator is configured to draw a fluid from the tank and distribute the fluid around a periphery of the agitator and toward the evaporator. An agitator and a method of manufacturing an immersion cooler are also provided.

Abstract: Hydrocarbon-containing feedstocks are processed to produce useful intermediates or products, such as fuels. For example, systems are described that can process a petroleum-containing feedstock, such as oil sands, oil shale, tar sands, and other naturally-occurring and synthetic materials that include both hydrocarbon components and solid matter, to obtain a useful intermediate or product.

Abstract: A method is provided for treating at least a portion of a well. The method includes the steps of: (a) simultaneously introducing into a mixer at least: (i) a first stream comprising water; (ii) a second stream comprising a dry, hydratable, viscosity-increasing agent for water, wherein the second stream is substantially free of water; and (iii) a third stream comprising a non-hydratable, insoluble particulate; wherein at least the first and second streams are not mixed prior to being introduced into the mixer; (b) mixing the first, second, and third streams in the mixer to form a pumpable mixture, wherein: (i) the mixer creates at least a sufficiently-high shear rate to disperse the viscosity-increasing agent and the insoluble particulate in the pumpable mixture; and (ii) the pumpable mixture has or is capable of developing a substantially-higher viscosity than the viscosity of the first stream; and (c) introducing a treatment fluid comprising the pumpable mixture into a wellbore.

Abstract: The disclosed device disperses a substance in a liquid. The device has at least one dispersing chamber, which has at least one liquid inlet, at least one substance inlet, and at least one outlet. At least one driving means is placed inside the dispersing chamber while serving to set the liquid inside the dispersing chamber in motion so that at least one cavity with varying volume forms in the liquid for drawing in the substance through the substance inlet and forcing the substance made wet with liquid through the outlet.

Abstract: Disclosed is a pump for controllably dispensing an additive into a stream of liquid and mixing therewith, the pump comprising: a pump body having a passage into which a liquid stream is introduced, and from which a combination mixture of the additive and the liquid stream is discharged; a turbine supported for rotation within the passage, the incoming liquid stream striking the turbine in a manner as to impart rotation thereon; an auger housing connected to the pump body, and having an entrance end into which an additive is introduced and an exit end from which the additive is discharged into the passage, such that the additive mixes with the incoming liquid stream; and a helical lifting auger mounted on a supporting drive shaft fixedly attached to the turbine, the auger rotatably disposed within the auger housing so as to produce a fluid flow through the auger housing, the lifting auger configured to accept the additive from the auger housing entrance end; and move the additive through the auger housing to t

Abstract: The present invention relates to a method and system for hydrating a gel for treating a wellbore penetrating a subterranean formation. The method includes directing a base fluid through an inlet into a mixer having an inner chamber housing a plurality of impellors extending radially from and rotating about a hub, causing a centrifugal motion of the base fluid, feeding a quantity of gel into the mixer, mixing the gel with the base fluid and discharging the now-hydrated gel from the inner chamber through an outlet of the mixer. A prewetting device may also be used. Thereafter, a variety of additives may be added to the gel fluid mix to form a fluid treatment to be introduced into a subterranean formation.

Abstract: A method of producing a fine particle dispersion characterized by having a dispersing step where, after fine particles have been sucked into a dispersing medium to prepare a suspension by a suction type stirring machine and bubbles have been removed from the suspension by a bubble removing means, the suspension is pressurized and introduced from the opposite directions so as to collide with each other, thereby dispersing the suspension.
