An automatic chemical solution formulating device combines and mixes stored solids and liquids into user specified formulations and dispenses those formulations into containers. Chemical solids are stored in cartridges of material separated into predetermined dosages (for example in reeled blister packs), avoiding the need for weighing during formulation. Elements include user interface, computer-controlled automated loading and unloading port for reagent-containing cartridges, cartridge conveyor system, reader for identifying cartridges, blister-pack strip drive system, punching mechanism to release reagents, portioning chamber to mix solvent with solids or liquids with optional portioning, accommodating formulation delivery port, position sensors, liquid flow measuring devices, liquid and gas pumps and valves, and label printer. The combination of these elements allows high-speed formulation and dispensing of user-specified formulations.

A method and device with an interface for manufacturing a customised product by mixing. The present invention concerns a device for manufacturing a customised product, and preferably a customised cosmetic product, by mixing at least two components housed in respective containers, at least one of the containers being a capsule (103), and at least one other container being a pot (11) comprising a nozzle, preferably a pump nozzle, at least one of said containers comprising an identification code, said device comprising an interface for collecting customised data, for example on a mobile phone or tablet. The invention also concerns a method for manufacturing a customised cosmetic product by homogeneously mixing components, using customised user data.

The invention relates to a mixing system for producing a cosmetic product. The invention also relates to a capsule (7, 8) containing a cosmetic compound. The mixing system allows the production of a cosmetic product from capsules (7, 8) comprising the raw materials required for the composition of such a cosmetic product, that is the cosmetic texturising agent, the cosmetic active substance and, as required, a cosmetic perfume. The invention is applicable in the cosmetic industry.

A beverage container has a housing, a controllable flow restriction element, and at least two liquid storage compartments in the housing. The housing is relatively rotatable with respect to the controllable flow restriction element about a main axis for rotation of the controllable flow restriction element between a closed liquid flow position and an open liquid flow position. The controllable flow restriction element has openings therein within the housing. Rotation of the controllable flow restriction element toward the closed position effects the closed position. Mixing of liquids from the first liquid compartment and the second liquid compartment are effected by rotational movement of the controllable flow restriction element.

A powder mixing system (12) includes a conduit (40) having a first end and an opposing second end, the conduit bounding a passage; a fluid pump (80) fluid coupled with the conduit, the fluid pump being configured to pump a liquid through the passage of the conduit; and a tubular transfer member (190) in fluid communication with the conduit, the transfer member being configured to couple with a powder bag housing a powder. The mixing system further including: (1) an eductor coupled to the transfer member and disposed in-line with the conduit so that the liquid pumped through the conduit also passes through the eductor; and/or (2) an auger assembly comprising an auger blade, at least a portion of the auger assembly being rotatably disposed within the transfer member.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems. The treatment fluid can comprise a water-based fracturing fluid or a waterless liquefied petroleum gas (LPG) fracturing fluid.

The invention relates an extrusion device (100) for extruding a semi¬finished product made of elastomeric material, comprising an extrusion body (10) extending along a feeding direction (A) and a pump (20) arranged downstream of the extrusion body (10) along said feeding direction (A). The extrusion body (10) comprises a hopper (30) for loading an elastomeric material and an extrusion screw (50) extending along said feeding direction (A) and having an inlet portion (50a) arranged close to the hopper (30) and an exit portion (50b) arranged close to the pump (20). The extrusion body (10) also comprises a motorised roller (40) arranged at the inlet portion (50a) of the extrusion screw (50) and configured to receive the elastomeric material from the hopper (30) and feed it to the extrusion screw (30). The extrusion screw (50) has a length and a diameter such that the ratio between length and diameter is comprised between 4 mm and 8 mm. The invention also relates to an extrusion process carried out through the aforementioned extrusion device (100).

Provided are an apparatus and a method for reaction for use in a co-precipitation reaction for preparing a catalyst or a cathode active material for a lithium secondary battery, which injects a raw material (a solution) at least between impellers according to the solution level in a vessel, thereby making a stirring speed uniform and, in particular, minimizing a concentration difference between solutions. The apparatus for the reaction may comprise: a reaction vessel; a stirring means provided inside the reaction vessel and having multistage impellers; and a raw material injecting means, comprising at least one injection nozzle connected to the reaction vessel, for injecting a raw material at least between impellers.

Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.
