A coating method has: a first step for mixing an active material, a binding agent, and a solvent, and obtaining a mixed slurry; a second step for adding an additive to the mixed slurry, stirring the mixed slurry and the additive, and obtaining a coating slurry and a third step for intermittently coating the coating slurry on a collector body, and forming a coated part and a non-coated part. In the second step, the addition amount of the additive is set in accordance with a preset coating speed of the coating slurry, or the weight of the coated part, and the additive includes castor oil, cellulose nanofibers, modified silicone, an amide, polyethylene oxide, propylene glycol monomethyl ether acetate, polyamine, and/or polycarboxylic acid.

A stirring wand is configured for selective engagement with a mixing device. The stirring wand comprises a substantially vertical portion having an upper end and a lower end, a first tapered surface that includes a first pitch angle proximate the upper end of the substantially vertical portion and a second pitch angle proximate the lower end of the substantially vertical portion, a substantially horizontal portion having a base and a distal tip, and a second tapered surface extending from the base to the distal tip. The second tapered surface includes a third pitch angle proximate the base and a fourth pitch angle proximate the tip.

The present invention provides for precision stirrers and mixers which are precision devices for the control of mixing and stirring in liquid and non-liquid systems. As will become obvious, the devices provided for in the present invention may be used for mixing or stirring by adjusting the device configurations and allow precise desired ingredient addition.

A method of coating particles includes dispensing particles into a vacuum chamber to form a particle bed in at least a lower portion of the chamber that forms a half-cylinder, evacuating the chamber through a vacuum port in an upper portion of the chamber, rotating a paddle assembly such that a plurality of paddles orbit a drive shaft to stir the particles in the particle bed, injecting a reactant or precursor gas through a plurality of channels into the lower portion of the chamber as the paddle assembly rotates to coat the particles, and injecting the reactant or precursor gas or a purge gas through the plurality of channels at a sufficiently high velocity such that the reactant or precursor a purge gas de-agglomerates particles in the particle bed.

An agitator rotor includes a shaft, rails, and a rod. The shaft defines a longitudinal axis. The rails extend radially from and are coupled to the shaft. The rails are separated from each other along a length of the shaft. Each rail includes a surface defining a non-zero angle with respect to the longitudinal axis of the shaft. The rod includes a first end coupled to a first one of the rails. The rod includes a second end coupled to a second one of the rails. A projection of the first end and the second end of the rod in a plane perpendicular to the longitudinal axis of the shaft defines a minor arc about a portion of the shaft.

Cosmetic blending devices for producing a cosmetic liquid from a solid-shell cosmetic ingredient capsule. The cosmetic blending devices include a lid, a base, a blending element configured to blend the capsule, and a drive mechanism configured to actuate the blending element. The cosmetic blending device may include a thermal element configured to change a temperature of the capsule. The thermal element may melt the capsule. The solid-shell cosmetic ingredient capsule comprises a shell defining an enclosed inner volume, and cosmetic material included in the enclosed inner volume. Methods of using the cosmetic blending devices comprise placing the solid-shell cosmetic ingredient capsule into the cosmetic blending device and blending the capsule to produce the cosmetic liquid. Methods of forming the solid-shell cosmetic ingredient capsule comprise forming a portion of the shell, adding the cosmetic material to the portion of the shell, and forming the remaining portion of the shell.
