A dispersion device is provided, including a container and a porous dispersion structure. The container has a first receiving space. The porous dispersion structure has at least three porous dispersion layers and has a second receiving space, wherein the porous dispersion structure is located in the first receiving space of the container.

A cosmetic preparation system may provide a diagnostic or shade matching tool, a dispenser unit, and a mixer unit. The diagnostic or shade matching tool may identify a user skin type and customize one or more ingredients to create a custom blend composition. The dispenser unit may dispense ingredients and prepare the custom blend composition in containers of various sizes. The mixer unit may provide a mixing assembly to mix the one or more ingredients using gyroscopic mixing.

A rotary bucket mixing device is disclosed. The rotary bucket mixing device includes a main body, a rotating disk assembly, a power gear assembly and a first idler assembly. The power gear assembly receives a power to drive the rotating disk assembly to rotate and thereby rotating a mixing bucket disposed on a supporting assembly of the rotating disk assembly and mixing the contents in the mixing bucket. The first idler assembly controls a rotational speed. The rotary bucket mixing device of the present disclosure provides a better support to the mixing bucket and therefore the safety during the mixing process is enhanced.

In one example, a build material supply system for additive manufacturing includes a mixer to aperiodically rotate a non-circular mixing chamber containing powdered build material to form mixed powdered build material.

A mixing container for a mixer, the container comprising, in exemplar embodiments, a cup and a lid, in which the lid has at least two sets of closely-spaced pins projecting therefrom. The sets of pins are spaced generally equidistant from each other and provide increased shearing of fluids or particulate matter being mixed within the cup.

In one example, a group of interchangeable supply modules to hold powdered build material for additive manufacturing. Each supply module in the group includes an exterior sized and shaped to fit into a mixer; an interior defining a non-circular mixing chamber, and an outlet through which powdered build material may leave the mixing chamber.

A resin dispensing apparatus includes a supply unit including a syringe having an internal space configured to hold a phosphor-containing resin. An agitator is disposed in the internal space. The supply unit is configured to rotate at least one of the syringe and the agitator to prevent settling of phosphor contained in the phosphor-containing resin. A discharge unit includes a cylinder having a discharge nozzle through which the phosphor-containing resin, received through a connecting pipe connected to the syringe, is discharged. A piston provides pressure to discharge the phosphor-containing resin through the discharge nozzle inside the cylinder.
