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 personal formulation device for mixing and dispensing customized formulations from ingredient reservoirs carried by the device. The device may include a plurality of miniaturized progressive pumps with a flexible coupling between the motor and the pump. The coupling may include a spring (40). The device may include a spacer sleeve (62) having an internal diameter tapered to closely follow the motion envelope of the spring (40). Each pump may include a retainer (60) that is threaded into the interior of the pump body (52) to retain the spacer sleeve (62) and the drive end (120) of the rotor (34). Each pump may include a stator with an integrated flange seal (36). The flange seal (36) may extend around the circumference of the stator and be sandwiched between portions of the pump body (52). The stator may have a noncircular shape that keys the stator within the pump body. The pump may include an optical metering system.

A GMK-reactor includes —a housing, —a hollow base attached to the housing; an inverse taper narrowing downward and attached to the top of housing, —a supporting tube passing through the base including an upper portion situated inside the housing and a bottom discharge opening, —a number of washers of predetermined shapes mounted on an outer surface of the upper portion of the supporting tube such that outer edges of the washer and the inner sidewalls of the housing form predetermined gaps therebetween, and —a number of inlets tangentially attached to the base for introducing a substance and a liquid thereinto forming a circulating suspension therein. The suspension flow, under external pressure, takes a vortex, laminar or turbulent form, rises along inner sidewalls of the housing, enters the gaps, changing its direction at the inverse taper, thus forming a cavitation zone, providing for grinding, or/and mixing of the suspension.

A substrate processing apparatus includes a spray nozzle that allows a plurality of liquid droplets to collide with a substrate held by a spin chuck, a liquid piping that supplies a mixed liquid of water and a chemical liquid to the spray nozzle, a first flow control valve and a second flow control valve each of which changes the concentration of the chemical liquid in the mixed liquid, and a controller that causes the liquid piping to supply the mixed liquid having a concentration of the chemical liquid determined in accordance with a substrate to be processed.

In an autoclave apparatus for a high-pressure acid leaching process which advances leaching by stirring heated and pressurized material slurry and sulfuric acid by stirrers in compartments in an autoclave main body of a plurality of compartments, transfers slurry from an upstream side compartment to a downstream one to advance leaching, liquid flow ports for slurry transfer that open and close by doors are provided on the partition walls, the liquid flow ports for slurry transfer are installed at positions where the heights from the lowermost portion the autoclave to the center of gravity are 0.1 to 0.3 times an autoclave diameter and distances from the center lines of the partition walls to the center of gravity are 0.05 to 0.25 times the autoclave diameter, and the liquid flow ports for slurry transfer have shapes which do not reach end portions of the partition walls.

An aeration nozzle is provided, having on one end an air supply port (16a) connected to an aeration pump (13) and a waste water suction port (17) for suctioning waste water in a processing tank (3, 4), and having a micro-bubble generation unit (18), provided facing the air supply port, for mixing air supplied by the air supply port and waste water suctioned from the waste water suction port and generating micro-bubbles (9), wherein a plurality of blades of cylindrical micro-bubble generators (19) included in the micro-bubble generation unit (18) is configured such that tip ends of the blades are formed so as to face one another around the center of the cylindrical micro-bubble generators (19a, 19b); and by being formed from an elastic member (such as rubber), the tip ends of the blades are configured so as to bend with the base ends as starting points.

Techniques or processes for efficiently producing concrete using dynamic feedback are disclosed. A concrete plant can use a control system to manage concrete production based on the dynamic feedback. The dynamic feedback can control mixing of concrete ingredients so as to yield uniform particle distribution for the concrete ingredients. The dynamic feedback can also avoid overflow situations as well as yield improved loading of the resulting concrete into a concrete transport vehicle (e.g., concrete truck).
