    Abstract: Apparatus and methods for physically separating a heterogeneous mixture of immiscible liquids utilizing the difference in the viscosities of the components. At least one moveable surface is enclosed by at least one stationary surface to form a processing passage. Viscous-drag-induced momentum is transferred preferentially from the moving surface(s) to the more viscous component of the mixture, moving it downstream toward a collecting and pressurizing obstructing member. The resulting pressure "squeezes" the less viscous droplets upstream to separate from the collected material and drain from the passage through a drainage opening.In a preferred embodiment, an annular channel rotates within a housing, dragging the mixture from an inlet to an obstructing member extending into the passage near an outlet. The separated less viscous component drains from a drainage opening in the housing, while the more viscous component is discharged through the outlet.

  • Patent number: 4475819
    Abstract: The invention is a pneumatic granular or seed applicator for fertilizer, herbicides or seeds and it includes a vertically situated auger assembly which is connected to the source of the material to be distributed. A distribution casing surrounds the upper discharge end of the auger assembly and blades or vanes are secured to the upper end of the auger shaft to radially distribute the material augered by the auger assembly, outwardly of the distribution casing. Discharge collars are situated around the base of the distribution casing and convey the material to discharge conduits which are conventional and which lead to the normal distribution heads and discharge devices. Air under pressure passes through venturi and assists in picking up the material from the discharge collars and conveys it to the various discharge conduits and thence to the individual ground engaging applicators, which are conventional.

  • Patent number: 4448535
    Abstract: Disclosed is an apparatus for blending sand and solid additives selectively and at selected rates into water for injection into a well. The apparatus may be truck mounted, and includes a frame, an input line with manifold and pump, a mixing tank, a variable venturi nozzle for delivering water to the tank, and an output line with pump, manifold, and recycle line. An auger delivers sand to the mixing tank. Dry chemicals are fed to the tank adjacent the variable venturi nozzle where the water is turbulent, at low pressure, and in high shear. Liquid chemicals may also be pumped into the tank.

  • Patent number: 4436431
    Abstract: A slurry mixing and pumping system adapted to automatically control both slurry viscosity and product output volume. Water and raw gypsum delivered to a mixing vat are thoroughly blended by a hydraulically powered agitator blade within the vat. Hydraulic pressure variations experienced by the agitator motor are translated into pneumatic viscosity control signals by a process controller. An air actuated water valve driven by the controller varies water input into the vat to effectuate viscosity correction. Means responsive to vat head level controls output volume.

  • Patent number: 4413933
    Abstract: This invention relates to pneumatic suction devices for removing slowly movable material from enclosed storage spaces, of the kind in which a suction pipe secured to a pivotable arm and having a supply of air arranged to be fed to a suction aperture thereof, is provided with peripherally distributed driven tools for loosening the material. According to the invention, at least three axially parallel drivable spindles are distributed around the end of the suction pipe, the spindles carrying, at least at the lower end thereof, tools for loosening the material and conveying it to the suction aperture and the suction pipe. Adjacent ones of the spindles are preferably rotatable in opposite directions, but at least two adjacent spindles out of an odd number of the spindles are rotatable in the same direction. The tools may include strip-shaped radial vane surfaces with bent-over ends substantially parallel to the spindles and arranged at an angle to the direction of rotation.

  • Patent number: 4375336
    Abstract: A machine for dispensing a doughy substance comprises a container capable of receiving gas under pressure and an outlet through which the doughy substance can be pushed on subjecting it to the pressure of the gas in the container. A rotor is disposed adjacent the outlet of the container and has a cavity in its external periphery. On rotation of the rotor, the cavity is capable of being brought into a position of alignment with the outlet to be filled with doughy substance pushed through the outlet. Further rotation of the rotor moves the cavity away from the outlet to a position at which the doughy substance can be released from the cavity, for example, by application of compressed gas to the base of the cavity through passages provided in the rotor. The container may comprise an arrangement for kneading the dough and may be provided with a blocking member to prevent passage of doughy substance through the outlet during the kneading operation.
