A mixing device for mixing a liquid plastics component with a gas, includes a liquid feed, a gas feed, and a discharge opening for discharging the mixture generated in the mixing device. Each of the liquid feed, gas feed, and discharge opening is connected to a mixing chamber in which a rotatable agitator device is arranged. A shaft for driving the agitator device projects out of the mixing chamber, and the mixing chamber is sealed off, in the region of the shaft, by a seal. On that side of the seal which is averted from the mixing chamber, there is a reservoir which is connected to the liquid feed and which is connected by a passage to the mixing chamber.

A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided on the aircraft, but is not activated and mixed with tank water until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and doses it with gel emulsion. Double elbows and/or the pump impeller fully activates the polymer gel. The activated polymer gel is mixed within the tank by one of a variety of systems including mixing paddles or sparging with gas. In one embodiment, a hollow tower of telescoping form has a float to keep an upper end near a surface in the tank and a sparging gas entry is a controlled distance below the surface, such that gas of limited pressure, such as from a ram air inlet can sparge and mix the water and activated polymer gel emulsion effectively.

A bioreactor system and packaging is provided. The bioreactor system includes a vessel for housing biomaterials for processing and a support structure. The vessel includes a flexible material defining a chamber and a mixing system positioned within the chamber. The mixing system includes an agitator for imparting motion and mixing to the contents of the vessel and includes a base affixed to the flexible material at a base section of the chamber, a shaft moveably mounted in the base and extending from the base into the chamber and at least one mixing element mounted to the shaft, the shaft configured to be driven by a motor magnetically coupled to the shaft and external to the lower portion of the chamber. The support structure is connected to the mixing system such that the shaft is moveable therein and configured to cooperate with an external structure to provide support for the shaft.

A modular flow monitoring package (MFMP) is provided for use in an additive delivery system. The MFMP may be manufactured as an add-on to be added to an existing additive delivery system, or may be incorporated into a cartridge or container structure. The MFMP includes a flow sensor for sensing flow of a base fluid and user actuator position sensors for sensing the position of one or more user actuated additive flow adjustment levers. A visual display, which may comprise an array of multi-color LED's may convey information to a user that is relevant to a user's use of the additive delivery system or the user's nutritional needs. Such information may include a current dosage of additive, being delivered, whether a recommended dosage of additive has been consumed, remaining life of a cartridge or supply of additive, and other data relative to health or performance monitoring.
