This disclosure relates to equipment utilized to manufacture chemical agents, particularly biopharmaceuticals. In some embodiments, reactor systems comprising a mobile carriage assembly; a disposable reaction container removably attached to the carriage assembly; and, a carriage holder into which the mobile carriage assembly may be removably inserted are provided.

The present invention relates to an apparatus for mixing an additive with a gas flow, in particular for an exhaust gas system of a vehicle having an internal combustion engine, that comprises a mixing chamber which can be flowed through by at least a portion of the gas flow, said mixing chamber having at least one inlet opening through which a main inlet flow of the gas flow flows into the mixing chamber on operation of the apparatus, having at least one metering opening and having at least one outlet opening. The apparatus further comprises a metering device by means of which an additive flow of the additive can be introduced into the mixing chamber through the metering opening, wherein the inlet opening and the metering opening are arranged and formed such that the main inlet flow and the additive flow in substantially opposite directions into the mixing chamber so that the main inlet flow and the additive flow impact one another.

A device for storing and circulating drinking water with vortex flow includes a base, a tank and an actuator housed in the base and configured to circulate the drinking water stored in the tank with vortex flow. The base includes an inlet port through which the drinking water is received and an outlet port through which the drinking water is dispensed. The tank is mounted on the base with a sealed engagement and is configured to store the drinking water. The tank has spherical or egg shape and includes an air inlet on an upper portion of the tank through which air can flow in and out of the tank.

Provided is a water carbonation unit including: at least one water feed and at least one pressurised carbon-dioxide feed; a merging duct extending between a first, closed end and a second end, the at least one water feed and at least one carbon-dioxide feed opening into said duct at said first end; said second end opening into a mixing chamber linked to a carbonated water outlet; the carbonated water outlet configured to restrict outflow of carbonated water from the chamber to thereby maintain pressure within the chamber while carbonated water flows out of the carbonated water outlet.

A carbonator reactor includes a cylindrical body, a nozzle for supplying a gas stream, inside the carbonator reactor and above the surface of a liquid phase and where the nozzle is located at the top of the reactor body, an inlet, an outlet, means for regulating the temperature and the pressure, a stirring system and at least one baffle regulating the stirring of the liquid phase and the mass transfer of the gas into the liquid surface, at least one impeller having inclined blades that make an angle from 5° to 60° with respect to the vertical axis. The reactor prepares sodium carbonate and has a configuration for the mass transfer of a gas phase in a liquid phase. A method for the preparation of sodium carbonate by means of the carbonator reactor by capturing CO.sub.2 in an NaOH aqueous solution, directly on the free surface of the liquid phase.

A mixing apparatus for mixing or stirring substances includes a mixing tank for receiving the substances, a rotor arranged in the mixing tank with which a vane for mixing or stirring the substances can be driven to rotate about an axial direction, and a stator arranged outside the mixing tank and with which the rotor can be driven contactlessly magnetically to rotate about the axial direction in the operating state and is supported magnetically with respect to the stator. A bar extends in the axial direction and is rotationally fixed to the rotor, and a limiting element fixed with respect to the mixing tank cooperates with the bar, with the limiting element being configured such that the bar rotates with respect to the limiting element and with a tilt of the rotor being limited by a physical contact between the bar and the limiting element.

The present disclosure relates to an aerosol delivery device filling system. The system includes multiple source containers each respectively including a differing aerosol precursor composition. The system further includes a mixing container configured to engage the source containers to receive and mix the aerosol precursor compositions to form a mixed aerosol precursor composition.
