Abstract: A bulk storage plant for providing cement mixtures oil well construction is disclosed. The bulk storage plant includes bulk storage sources, an additive station, a weigh batcher, and a tumble blender. The bulk storage sources are adapted to contain cement ingredients. The additive station is adapted to provide an additive for adjusting cement properties. The weigh batcher is connected to the bulk storage silos and the additive station. The weigh batcher is adapted to receive the cement ingredients from the bulk storage sources and the additive from the additive station. The tumble blender is connected to the weigh batcher and is adapted to receive the cement ingredients and the additive from the weigh batcher. The tumble blender is adapted to blend the ingredients and provide the blended ingredients to one of a temporary storage silo and a storage vessel for transport to the oil well site.

Abstract: A mixer of the present invention includes an outer cylinder into which powder material is loaded, a rotational axis which is located coaxially with the outer cylinder and discharges liquid material while forming the liquid material to fine particles, and a fin which has a rectangular shape and is disposed along an inner wall of the outer cylinder. The fin is independently revolvable around the rotational axis. The fin has side faces in a direction of revolution of the fin, each of which forms an inclined face such that a width of the fin becomes wider from an inner surface to an outer surface of the fin.

Abstract: An agitation/deaeration apparatus is provided which causes a container containing a viscous to-be-kneaded object to be rotated and revolved simultaneously, to agitate and deaerate the to-be-kneaded object, wherein piping (wiring) connecting the container and an external device is prevented from twisting even when the container rotates.

Abstract: A self-purging auxiliary fluid supply system for supplying washout or makeup water or other fluids under pressure to a truck-mounted concrete mixing/dispensing drum is disclosed. The system includes a truck-mounted fluid reservoir for containing a quantity of fluid connected to supply fluid to an air-operated diaphragm pump connected to supply auxiliary fluid from the fluid reservoir under pressure to a discharge assembly. The pump further provides an integral purge system for displacing fluid in the fluid supply system after use.

Abstract: A rotary slurrifier of this invention comprises a pair of spinning discs, which throw a first fluid into a larger mass of second fluid in paired and flow connected impact cavities, within a counter-rotating cavity shell. The first fluid is to be largely insoluble in the second fluid. Impact of the first fluid with the larger mass of second fluid, in the impact cavities, causes atomization of the first fluid into a slurry of many small first fluid particles suspended in a continuous phase of second fluid. The final slurry flows out of the rotating cavity shell via a slowdown reaction turbine. High viscosity residual petroleum fuels and tars as first fluids can be thusly preatomized in a fuel in water slurry, and can then be cleanly and efficiently burned in small bore, high speed, diesel engines, which now require use of expensive low viscosity distillate fuels, which are in short supply.

Abstract: An agitating retort (100) includes an outer shell (102) within which the drum structure (112) is disposed for rotation within the shell while supporting a number of baskets (114) for holding products to be processed within the retort. Processing fluid is applied to the interior of the shell (102) through a rotary coupling (115) disposed within the shell. The coupling routes processing fluid to a distribution system (116) to outlet holes or nozzles (118) positioned within the drum structure (112).

Abstract: A mixer for alginate has a rotatable bowl and one or more nozzles positioned above the opening of the rotatable bowl for injecting water into the bowl. By controlling the injection of water at appropriate locations and at appropriate strengths (i.e., pressures and rates), desired mixing of the alginate can be achieved.

Abstract: An apparatus and method for mixing at least two reactants is taught wherein a first reactant is delivered to a reaction zone through a first annular flow path and a second reactant is delivered to the reaction zone through a second annular flow path. The first and second annular flow paths are concentric with one another and the two reactants intermix with one another in the reaction zone. There is a rotating disc having a surface, defining one boundary of the reaction zone. The flow of the first and second reactants across the rotating disc and through the reaction zone is generally radial and has a residence time in the reaction zone of not more than about 100 msec, and preferably not more than about 50 msec. The reaction zone resides in a main reactor vessel and there is a driven agitator residing in the main reactor vessel to stir the contents thereof.
