Abstract:
A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided but gel emulsion is not activated and mixed with water in the tank until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and returns water back to the tank with a dose of gel emulsion supplied therein. Double elbows and/or the pump impeller fully activates the polymer gel. The activated polymer gel is mixed within the tank by one of a variety of systems including sparging with air, routing of return water from the pump through nozzles and providing a baffle for generating circulatory mixing flow within the tank, or utilizing a mixer element which moves dynamically within the tank. Hydrodynamic forces associated with the aircraft passing over a body of water can power dosing of the water with polymer gel emulsion.
Abstract:
Apparatus (20) for injection of fluid into extrusion system components such as a preconditioner (24) or extruder (100) is provided, preferably as a composite assembly including a fluid injection valve (52) and an interconnected static mixer section (54). Alternately, use may be made of the fluid injection valve (52) or static mixer section (54) alone. The invention greatly simplifies the fluid injection apparatus used in extrusion systems, while giving more efficient absorption of thermal energy with a minimum of environmental contamination, and the ability to inject multiple streams into the extrusion systems.

Abstract:
The method of producing a colored powder of a polymeric material includes the steps of selecting a feedstock of said polymeric material, pulverizing said polymeric material in a pulverizer to produce a powder, moving the powder directly from the pulverizer to a mixer; spraying a liquid formulation including a colorant into the powder within the mixer, and mixing the liquid formulation and powder.
Abstract:
Processes for continuously producing latex emulsions are disclosed. A multi-screw extruder is used for the production of the emulsion. A resin is fed into the extruder, heated, optionally dissolved in a solvent, mixed with a base to neutralize the resin and form particles, then mixed with a surfactant and water to form a phase inverted emulsion (PIE). The PIE may be sent to a distillation column to separate out the solvent, and the resulting latex emulsion is then sent to a receiving tank. These processes are useful for making precursors for toner compositions.
Abstract:
A new device and process for continuously applying coatings, such as resin and additives or polymers or the like, to minerals are disclosed. The device and apparatus differ substantially from standard batch coating processes currently used by industry. The apparatus uses a horizontal cylinder with an internal auger and a series of injection ports distributed along the cylinder. Minerals that are to be coated are pretreated and passed through the mixing cylinder using the auger (which may comprise one or more screws with variable pitch blades). As the mineral particles pass through the cylinder various coating materials are injected by the injection ports. The complete system is described, the method of use is explained and the control system which allows for different products is described.
Abstract:
The present invention provides a soil cement manufacturing machine which prevents blades of an impeller from becoming worn and prevents soil cement from becoming stuck to and remaining in a mixing tub. The soil cement manufacturing machine includes an input part (100), which is provided for supplying soil and cement, and a mixing tub (210). The mixing tub (210) has an inlet port (220), an outlet port (230), through which mixed soil cement is discharged, and a nozzle (250) provided above the outlet port (230). The oil cement manufacturing machine further includes impellers (300), which are provided in the mixing tub (210) to mix soil and cement. Each impeller has a circular part (310) and blades (320), which are radially fastened to the circular plate. At least one impeller (300) has at least one blade which is longer than remaining blades thereof, and is provided with a scraping blade 330 having a T-shaped end.
Abstract:
A waste treatment apparatus decomposes waste by the microorganisms to perform annihilation treatment. The waste treatment apparatus includes a treatment tank which accommodates the microorganisms together with the waste, and an agitation device arranged to agitate the microorganisms together with the waste. The agitation device includes a plurality of agitating tools arranged at predetermined intervals in the axial direction of a rotation shaft. The agitating tools have paddle arms, respectively, which are disposed so as to be opposed to each other in a diameter direction of the rotation shaft, and blades, respectively, which are disposed at predetermined distances apart from an inner wall of the treatment tank and are inclined with respect to the axis of the paddle arms. The blade on one side is inclined forward in a direction in which the front side thereof with respect to the rotation direction of the paddle arm approaches the rotation shaft. The blade on the other side is inclined backward in a direction in which the rear side thereof with respect to the rotation direction of the paddle arm 70b approaches the rotation shaft.

A pump operably connected to the blender pumps the mixture from the blender. At least two mixing chambers are arranged in parallel, wherein at least one of the mixing chambers is configured to receive a flow of the mixture from the pump, and wherein each of the mixing chambers has a plurality of atomization nozzles formed on a surface thereof along at least a portion of the length of the mixing chamber. The atomization nozzles are configured to receive a measured amount of water proportional to the stoichiometric mixture therethrough. A mixer, which is removably mounted in the mixing chamber, is configured to generate turbulence in the flow of the mixture as it passes through the mixing chamber.
