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 bench or stand mixer includes a bowl that contains ingredients, a motor that drives an accessory, for example a beater, to process the ingredients, and a sensor. The sensor provides a signal indicative of a change in the ingredients, with the sensor cooperating with a controller, for example a processor, to control the speed of the motor, in response to the change in condition of the ingredients.

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.

A dispersion device includes a stirring and mixing unit that mixes a powder with a liquid, a powder feed unit that feeds the powder to the stirring and mixing unit, and a dry gas generation unit that supplies a dry gas to the powder feed unit. The powder feed unit is sealable.

An inline buffer dilution system is provided that includes a first flow control valve fluidly connected to a supply of diluent liquid, second and third flow control valves fluidly connected to supplies of a first buffer and a second buffer, respectively, and a mixing pump fluidly connected to the first, second, and third flow control valves and configured to mix an amount of the diluent liquid, the first buffer, and the second buffer to produce a diluted buffer solution. The system further includes a backpressure control valve configured to generate a backpressure that promotes mixing within the mixing pump, and a controller configured to control the backpressure based on the amount of the diluent liquid, the first buffer, and the second buffer being mixed in the mixing pump, such that the mixing pump yields a minimum mixing threshold across a range of fluid flows.

A tumbler crystallizer for crystallizing pelleted, tacky, polymeric materials includes a housing for rotatably supporting a removable paneled drum on rollers. The removable panels may be made of a transparent, heat-insulating material. The drum receives a flow of hot pellets through an inlet chute, and a tumbling action of the drum and internal agitators keeps the pellets in motion relative to each other to prevent agglomeration until they reach a desired level of crystallinity and are no longer tacky. Baffle plates are provided at intervals along the length of the drum to slow the flow of pellets therethrough to increase residence time. Damper plates are provided near the exit end of the drum to aid in building a bed of pellets within the drum, and also to control residence time of the pellets within the drum.

An exhaust aftertreatment system for an internal combustion engine includes an outer casing defining an exhaust flow path for exhaust gases from the internal combustion engine, a selective catalytic reduction unit provided in the exhaust flow path for reducing nitrogen oxides, a urea dosing device for adding urea to the exhaust flow upstream of the selective catalytic reduction unit, and a rotatable mixer device for mixing the urea with exhaust gases upstream of the selective catalytic reduction unit. The exhaust aftertreatment system further comprises an air inlet valve provided upstream of the mixer device for introducing air into the exhaust flow path, and an electric motor arranged for rotating the mixer device to create a suction of air into the exhaust flow path via the air inlet valve.

A gas solution manufacturing device 1 includes a gas supply line 2 configured to supply a gas as a raw material of a gas solution, a liquid supply line 3 configured to supply a liquid as a raw material of the gas solution, a gas solution production unit 4 configured to mix the gas and the liquid together to produce the gas solution, a gas-liquid separation unit 5 configured to perform gas-liquid separation of the produced gas solution into a supplied liquid to be supplied to a use point and a discharged gas to be discharged through an exhaust port, and a gas dissolving unit 6 provided in the liquid supply line 4 and configured to dissolve the discharged gas resulting from the gas-liquid separation in the liquid. The gas dissolving unit 6 is configured with a hollow fiber membrane configured with a gas permeable membrane.

A small-scale, batch-wise device to simulate high-shear, short-duration emulsification of fluids from various industrial processes at elevated temperatures and pressures for the purpose of determining the quality and stability of those emulsions under different conditions and with different additives. A threaded, transparent tube capable high temperature and pressure is fitted with a threaded bearing with a shaft sealed gas tight at two points with spring-loaded, internally-facing, open rings. A socket head on the external end of the shaft held on a high-speed motor-drive rotates mixing blades on the internal end of the shaft. Process fluids and additives are added to the tube with a vaporizing liquid. The tube is sealed, heated to the process temperature under pressure, then inverted onto the motor drive, by which the blades are rotated at high-speed for a short duration. The tube is righted and the emulsion observed over time at process temperature under pressure.
