A molded product production system includes a powdery material mixing and feeding device configured to feed mixed powdery materials including at least two types of powdery materials, a filler configured to fill, with the mixed powdery materials fed by the powdery material mixing and feeding device, a die bore of a compression-molding machine, a sensor configured to measure a mixing degree of the mixed powdery materials fed by the powdery material mixing and feeding device, and a molded product removal mechanism configured to distinguish a molded product obtained by compression molding mixed powdery materials having a mixing degree measured by the sensor out of a predetermined range from a molded product obtained by compression molding mixed powdery materials having a mixing degree within the predetermined range.

A powdery material mixing degree measurement device includes a discharger configured to discharge mixed powdery materials to a filler configured to fill, with the powdery materials, a vertically penetrating die bore of a compression-molding machine including a table including the die bore, a slidable lower punch including an upper end inserted to the die bore, and a slidable upper punch including a lower end inserted to the die bore, a plurality of movable portions configured to move the mixed powdery materials to the discharger, and a sensor configured to measure a mixing degree of the mixed powdery materials in the movable portions.

The system and method of the invention pertains to an axial flux stator is implemented to replace the drive-end magnets and the drive motor. The axial flux stator comprises a control circuit to control the voltage and current provided to the stator, to measure the torque and speed of rotation, and to measure the magnetic flux and magnetic flux density produced by the axial flux stator and impeller magnets, individually or in combination. The axial flux stator comprises a plurality of current carrying elements to produce magnetic flux in an axial direction and drive the impeller.

The system and method of the invention pertains to use of a back iron on one or both ends of the impeller to increase the magnetic field density, and thus strengthen the magnetic coupling. In addition, pie-shaped (i.e. wedge) magnets, or variations thereof, increase the utilization volume and hence provide higher torque to allow the use of less expensive material (e.g. ferrites). In another embodiment, the rotor side is constructed with a Halbach array which increases the torque without the need to add a back iron piece. In another embodiment, an axial flux stator is implemented to replace the drive-end magnets and the drive motor.

A method of controlling a portable appliance includes measuring an input current supplied to a motor of the portable appliance and measuring a rotational speed of a shaft of the motor. The method also includes determining a current limit based on the rotational speed of the shaft using a substantially continuous function which relates a domain of rotational speeds to a range of current limits. The method further includes reducing, when the input current exceeds the current limit, the rotational speed of the shaft incrementally along the substantially continuous function until the input current is approximately equal to the current limit.

A device and a method for adjusting stirring blades on a stirring blade receptacle of a stirrer, wherein the stirring blades can be fixed with a stirring blade axis in receiving bores, which are arranged transversely to an axis of rotation and are a part of the stirring blade receptacle, at intended predetermined angle of attack relative to a virtual plane that is arranged transversely to the axis of rotation of the stirrer. An associated device body is provided with a receiving element for receiving the stirring blade receptacle with unfixed stirring blades. A stop is arranged on the device body for each lower face, which faces the receiving element and is a part of the stirring blades, outside the respective stirring blade axis. Each respective stirring blade is then brought into abutment against its associated stop, to place it into the predetermined angle of attack.

A baby bottle blender includes a baby bottle having a top collar with external threads and a bottom collar with external threads. A nipple has an anti-colic air vent. The nipple cap is internally threaded to be removable threaded onto the top collar of the baby bottle and holds the nipple extending through a central aperture of the nipple cap onto the top collar. A top cover snaps over the nipple cap and covers the nipple. An agitating unit is centrally retained within a bottom attaching cap of the baby bottle. Next, a base member has a top recess to engage with the agitating unit in the bottom attaching cap on the baby bottle. An electrical mechanism in the base member is for operating the agitating unit, so that the agitating unit will mix formula within a liquid placed through the top collar of the baby bottle in approximately seven (7) seconds to thoroughly blend the formula.

The present invention relates to a method for flocculating and dewatering oil sands fine tailings. Said method comprises mixing the aqueous mineral suspension with a poly(ethylene oxide) (co)polymer to form a dough-like material. The material is then dynamically mixed in an in-line reactor to break down the dough-like material to form microflocs having an average size of 1 to 500 microns, and to release water. The internal diameter of the in-line reactor is at most five times the internal diameter of the inlet pipe of the reactor. The suspension of microflocs has a viscosity of at most 1000 cP and a yield stress of at most 300 Pa.

A device, method, and system for precision measurement, dispensing, and mixing of ingredients. The device includes an ingredient container and a base unit. The ingredient container includes a dispensing mechanism selectively driven to dispense the ingredients from a lower aperture thereof. The base unit includes at least one drive motor, a mixing mechanism, and a dispensing aperture extending through the base unit and configured to allow the quantity of ingredients dispensed from the ingredient container to pass through the base unit to a removable mixing bowl. The base unit may selectively operate in a dispensing mode that drives the dispensing mechanism and in a mixing mode that drives the mixing mechanism to rotate a mixing component removably coupled to the base unit and configured to extend into the removable mixing bowl for mixing the quantity of the ingredients dispensed from the ingredient container into the removable mixing bowl.
