An exemplary compounding system and device for mixing materials can include a housing, a first material source and a second material source. A first fluid line can be operationally connected to the housing and configured to transport a first volume of fluid per unit time from the first material source to a final container. A second fluid line can be operationally connected to the housing and configured to transport a second volume of fluid per unit time from the second material source to the final container. The device can also include a pump system including, a first pump having a first rotor and a first platen which secures the first fluid line between the first rotor and the first platen, the first pump being configured to move the first volume of fluid through the first fluid line, and a second pump having a second rotor and a second platen which secures the second fluid line between the second rotor and the second platen, the second pump being configured to move the second volume of fluid through the second fluid line. A first platen lock can be provided and can be rotated in a first direction to lock the first platen in a closed position relative to the first rotor, and wherein rotation of the first rotor draws the first material source through the first fluid line. The pump system can also be configured such that the volume of fluid per unit time delivered by the first and second pumps is different, and/or where the first and second pumps have different head characteristics.

Methods, systems, and devices, are developed for in-situ placement of a concrete mix that can have the thixotropy to hold vertical dimension without containment, while maintaining pliability to be pumped into place and manipulated to a desired shape, and can be combined with concrete set accelerators, allowing subsequent layers of this concrete mix to be continuously stacked in place to build tall walls and such without the use of forms. Concrete without these special properties is pumped toward the point of placement where it is modified by injecting and mixing, into that line of pumped concrete, an admixture containing thixotropes, thickeners and/or set accelerators or other modifiers to provide these properties and other improvements. This method allows conventional plant batching with commonly available constituent materials for batching an economical concrete that is delivered to a jobsite and then is pumped most of the way to a point of placement.

In order to efficiently produce a liquid containing ultrafine bubbles of a desired gas, an ultrafine bubble-containing liquid producing apparatus includes a gas dissolving unit that dissolves a predetermined gas into a liquid, and a UFB generating unit that generates ultrafine bubbles in the liquid in which the predetermined gas is dissolved. A CPU performs control under a first condition in a case of causing the gas dissolving unit to operate in a circulation route passing through the dissolving unit. The CPU performs control under a second condition different from the first condition in a case of causing the UFB generating unit to operate in a circulation route passing through the UFB generating unit.

An automatic variable speed eductor recirculation system for metal recycling furnaces having a delacquering chamber and a separate heating chamber. The system includes a recirculation duct between the two chambers, an eductor in the duct, a variable speed blower forcing motive gases into the eductor creating a Venturi that draws VOC's from the delaquering chamber through the eductor, and an infrared opacity sensor proximate the eductor that measures the transparency level of the gases in the eductor. An electronic controller automatically adjusts the blower speed to control the eductor Venturi based upon the transparency level measurements of the opacity sensor.

A steam shower device includes a steam enclosure, including a front plate with first and second vacuum air vents, a rear wall, and a steam chamber; a steam mixing valve with a steam control dial; a mixed water line; a steam nozzle assembly with a stem nozzle head; a steam vent, including a perimeter wall and a perimeter ledge; a visual trim panel; a hot water pan; such that the steam vent is configured to emit steam from the steam chamber. Optionally, the steam shower device can include a hand-held steam hose, which is detachably connectable to the steam vent.

A beverage dispensing system is disclosed that includes a container assembly configured to store two liquids (e.g., liquor and a mixer) that is couplable to a head assembly. The head assembly includes one or more pumps configured to draw the different liquids from the assembly, to mix variable ratios of the two liquids together, and to dispense the drink. In some configurations, the drink may be dispensed from the beverage dispenser into a glass or directly to the mouth of an individual.

A polymer flocculant mixing and dissolving system comprising: a mixing tank (2) in which a solid polymer flocculant is mixed with water used as a solvent; a liquid feed unit (3) for feeding an aqueous solution containing the polymer flocculant from the mixing tank; a regenerative mixer (4A,4B) used to mix and dissolve the polymer flocculant by applying pressure to the aqueous solution containing the polymer flocculant fed from the liquid feed unit while forming a vortex flow; a process channel (61) through which the aqueous solution that has passed through the regenerative mixer is fed to a downstream process; a circulation channel (62) through which the aqueous solution is returned to a position on an upstream side of the liquid feed unit; and a flow rate adjusting unit (6) for adjusting a balance between a flow rate of the aqueous solution flowing through the process channel and a flow rate of the aqueous solution flowing through the circulation channel. The polymer flocculant mixing and dissolving system can stably supply the solution in an amount required in the downstream process.

A lipid nanoparticles manufacturing chip includes a mixer unit for forming a mixed solution by mixing a first raw material containing an active ingredient and a second raw material containing a lipid, a dilution unit that is connected to the mixer unit and dilutes the mixed solution using a diluent solution to make a diluted mixed solution, and a concentration unit connected to the dilution unit and for obtaining a concentrated solution by concentrating lipid nanoparticles (LNP) from the diluted mixed solution.
