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.

The invention relates to methods for the chemical application of coatings by the decay of gaseous compounds, in particular to methods for injecting gases into a reaction chamber. The invention also relates to means for feeding gases into a reaction chamber, said means providing for the regulation of streams of reactive gases, and ensures the possibility of obtaining multi-layer epitaxial structures having set parameters and based on nitrides of group III metals while simultaneously increasing the productivity and cost-effectiveness of the process of the epitaxial growth thereof. Before being fed into a reactor, all of the gas streams are sent to a mixing chamber connected to the reactor, and are then fed into the reactor via a flux former under laminar flow conditions. The mixing chamber and the flux former are equipped with means for maintaining a set temperature. As a result of these solutions, a gaseous mixture with set parameters is fed into the reactor, and the formation of vortices is simultaneously prevented. The maximum allowable volume of the mixing chamber is chosen to take into account the process parameters and the required rarity of heterojunctions.

A carbonated beverage maker includes a water reservoir, a carbon dioxide creation chamber, and a carbonation chamber. The water reservoir holds ice water and has a first impeller and a shroud surrounding the first impeller. The carbon dioxide creation chamber contains chemical elements and receives warm water. The chemical elements react with each other to create carbon dioxide when the warm water is introduced to the carbon dioxide creation chamber. The carbonation chamber is connected to the water reservoir and the carbon dioxide creation chamber. The carbonation chamber has a second impeller that includes a stem portion and blades. The stem portion and the blades define conduits therein. The blades create a low pressure region in a lower portion of the carbonation chamber such that carbon dioxide from the carbon dioxide creation chamber flows through the conduits to the low pressure region.

An example device with a microfluidic channel for use in a chamber is provided, the example device comprising: a chamber to contain a fluid; a microfluidic channel located internal to the chamber, the microfluidic channel having an entrance within the chamber and an exit within the chamber, the microfluidic channel defined by a housing located within the chamber; a unidirectional displacement mechanism inside the microfluidic channel, the unidirectional displacement mechanism located between the entrance and the exit; and a controller to activate the unidirectional displacement mechanism to cause the fluid from the chamber to enter the microfluidic channel via the entrance and leave the microfluidic channel via the exit thereby agitating the fluid within the chamber, the fluid otherwise being non-moving.

The present invention relates to a hand mixer having a heat activation function. The heat activation function preferably allows a user to heat ingredients that are to be mixed by a hand mixer. The hand mixer may include a cavity that has each of a fan, a motor to drive the fan, heated coils, and an output area or mouth. When a user wishes to activate the heating function to soften ingredients in a bowl or other vessel to be mixed, he or she may use a controller to activate the fan and blow air through the heated coils and out from the output area toward the ingredients to be mixed and/or mixing devices used to mix the ingredients, so that the ingredients may be softened.

A polymer dispersion system for use in a hydraulic fracturing operation is disclosed. The system comprises (a) a tank assembly comprising an ingress, an egress, and an interior volume for collecting mother solution; (b) a first transfer pump coupled with the egress of the tank assembly: and (c) a second transfer pump coupled with the egress of the tank assembly. The first transfer pump is configured for coupling to a missile unit and a blender unit downstream thereof, but in fluid communication with only one of such units at any given time when coupled. A method of operating said polymer dispersion system is also disclosed.
