A device for closing a delivery head of a dispensing machine for delivering fluid products includes a stationary support, a drive shaft, which rotates with respect to the stationary support around a vertical axis, and can be moved with respect to the stationary support along the same vertical axis, a cup-shaped closing element carried at the distal end of an arm fixed to a lower end of the drive shaft, and a screw and nut mechanism which controls a translation of the closing element in the direction of the longitudinal axis and a rotation movement to the longitudinal axis using a single actuator.

A method and apparatus for obtaining a product chemistry from a solid block is provided. The product is housed within a dispenser, which utilizes a liquid and a gas to erode the block and produce a concentrate solution. The liquid and gas characteristics can be adjusted in the field to achieve a predetermined concentrate level in the solution. The introduction of air into the dispenser saves water, while producing higher concentrate levels.

Embodiments of a system and a method for continuously manufacturing a joint compound can be used to produce ready mix joint compound. The system includes means for continuously mixing wet and dry joint compound ingredients together and means for homogenizing multiple volumetric units of mixed joint compound to reduce variation in at least one joint compound material property (e.g., viscosity) across multiple successively produced volumetric units of mixed joint compound (relating to standard commercial packaging sizes for joint compound, such as five-gallon pails, for example) relative to the material property of the respective multiple volumetric units before passing through the means for homogenizing.

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 tubular structure for producing droplets and a method of using the tubular structure to produce droplets are provided. The tubular structure includes microchannel structures, and is used for droplet generation, droplet collection, nucleic acid amplification and/or in situ droplet detection, etc.

A mixer, particularly a dual planetary mixer, for mixing a liquid with a dry material in a mixing vessel has improved fluid introduction. The mixer includes a drive shaft rotatable about a main axis of rotation and at least a first mixing element rotatable about a first mixing element axis. The mixer further includes drive means for driving the first mixing element about the first mixing element axis in response to rotation of the drive shaft about the main axis of rotation and at least one injection nozzle for injecting a liquid. A fluid path extends between a liquid inlet and the at least one injection nozzle. The fluid path extends longitudinally through the drive shaft.

A method of generating a low-CFM fog with a portable, battery-powered fogging apparatus is provided. Airflow is initiated through at least one passageway of fogging apparatus with a DC powered blower motor receiving power from at least one battery. A quantity of pressurized fogging liquid is expelled through a nozzle positioned proximate to an opening within a mixing chamber, wherein the quantity of pressurized fogging liquid exits the nozzle with at least 90% of an atomized micron particulate size between 5 and 60 microns. The expelled quantity of pressurized fogging liquid is atomized with the airflow to produce a fog at 190 CFM and at a velocity of less than 190 MPH.

An apparatus for accommodation and dispensing of miscible materials has an accommodation vessel having a lower region in the form of a truncated cone, with a lower discharge opening in the direction of gravity, and ha a mixing mechanism shaft disposed centrally in a mixing space, which shaft has at least one mixing mechanism that revolves in the accommodation vessel. The discharge opening is provided with a displacer apparatus that projects into the interior of the lower region of the accommodation vessel. The lower end of the mixing screw or mixing spiral of the mixing mechanism projects into the approximately V-shaped channel between the lower vessel wall and the displacer apparatus.

A positive active material manufacturing method according to an exemplary embodiment of the present invention includes: a step of preparing a lithium-containing compound; a step of manufacturing a coating liquid including at least one coating element; a step of mixing the lithium-containing compound and the coating liquid to form a coating mixture of a clay or slurry state; and a step of agitating the coating mixture. Further, a manufacturing apparatus of a positive active material according to an exemplary embodiment includes a rotation container, a cover, a nozzle, and an agitation wing.

A portable fogger apparatus includes a portable fogger body having at least one airflow passageway. A DC blower motor is connected to the fogger body proximate to the airflow passageway and receives power from a battery, wherein the DC blower motor produces an airflow through the passageway. A mixing chamber is positioned along the at least one passageway, wherein at least a portion of the airflow is movable through the mixing chamber. A quantity of pressurized fogging liquid is housed within a container connected to the fogger body. The pressurized fogging liquid is dispensable from the container into the mixing chamber where it is expelled through a nozzle and mixed with the airflow to produce a fog. The fog has an atomized micron particulate size between 5 and 60 microns. An activation switch controls activation of the DC blower motor and/or dispensing of the pressurized fogging liquid.
