An apparatus for manufacturing nanocomposite-ink, the apparatus comprising, a nanoparticle reservoir, an organic-matrix reservoir, a homogenizer, and a dispenser. The homogenizer combines the nanoparticles and the organic-matrix, dispersing the nanoparticles within the organic-matrix, thereby producing a nanocomposite-ink for dispensement by the dispenser.

Processes for continuously coalescing particles from an aggregated particle slurry are disclosed. The aggregated particle slurry is heated, then coalesced by raising the pH. The coalesced particles are homogenized and exit as a coalesced particle slurry. A multi-screw extruder is used for the coalescing. These processes are useful for providing coalesced particles such as toner compositions.

A system structure of an impeller for a dispersion-emulsion apparatus based on dual rotor is provided. This system includes an impeller unit in which an impeller constituted by a first rotor and a second rotor is configured in multi stages, in which the first rotor and the second rotor are driven in reverse rotational states to each other by driving motors of the respective rotors and respective target materials to be mixed sequentially pass between the multi-stage impeller units at once by a one-pass method, and as a result, a total working time for processing of dispersion-emulsion is significantly shortened, uniformity of a particle size is enhanced by micro shearing (cutting) of the respective mixed materials.

Provided is a continuous reaction apparatus which can precisely control the path of flow of the liquid reaction mixture in the reaction vessel. Further, provided is a continuous reaction apparatus which can efficiently mix the liquid reaction mixture in the reaction vessel. The continuous reaction apparatus comprises a plurality of mixing vessel units and a plurality of partition units. These units are connected in the state of being alternately stacked on one another. Each mixing vessel unit has an agitating blade disposed in the inner space thereof. The relationship between the inner diameter D1 of the mixing vessel unit, the height H of the mixing vessel unit, and the outer diameter d1 of the agitating blade satisfies the formula (1): 10(D1/H)1.5, and the formula (2): 0.99(d1/D1)0.7. The agitating blade is a circular disc-type agitating blade.

An ink vial mixing device includes a case which defines a mixing area. The case includes a door that is hingedly coupled to the case for opening and closing the mixing area. A mixing unit is rotatably integrated into the case such that the mixing unit is positioned in the mixing area defined in the case. A plurality of ink vials is provided and each of the plurality of ink vials contains a fluid ink. A plurality of couplers is each attached to the mixing unit and each of the plurality of couplers releasably engages a respective one of the plurality of ink vials. The couplers are radially arranged on the mixing unit such that each of the plurality of ink vials is exposed to centrifugal force when the mixing unit rotates for mixing the fluid ink contained in each of the plurality of ink vials.

A tattoo ink mixing device for mixing and generating customized colors of tattoo inks includes a housing having an interior space. Each of a set of ink cartridges positionable in the interior space holds a respective one of a plurality of colored inks. Each of a plurality of cartridge pumps positioned in the interior space is fluidly couplable to a respective one of the set of ink cartridges. The plurality of cartridge pumps release a quantity of the respective one of the plurality of colored inks from the respective one of the set of ink cartridges. A mixing bowl positioned in the interior space is fluidly coupled with each of the plurality of cartridge pumps to receive the quantity of the respective one of the plurality of colored inks, which mixes with an additional quantity of an additional one of the plurality of colored inks thereby forming a mixed ink.

A tattoo ink mixing apparatus has a housing having a cavity, a plunger movable between a first position and a second position, and a dynamic member disposed in the cavity and adapted to engage with the plunger distal end. The dynamic member moves in response to movement of the plunger and alternatively creates a suction force and an expulsion force in the opening of the distal end of the housing as the plunger moves between its first and second positions.
