A pneumatic bioreactor includes a vessel containing a fluid to be mixed and at least one mixing device driven by gas pressure. A first embodiment includes a floating impeller that rises and falls in the fluid as gas bubbles carry it upward to the surface where the gas is then vented, permitting the impeller to sink in the fluid. The floating impeller may be tethered to a second impeller with a flexible member and pulley. The mixing speed is controlled with electromagnets in the vessel acting upon magnetic material in the impeller or its guides. In another embodiment, floating pistons mix the fluid, pushing it through a mixing plate with one or more apertures. In a third embodiment, the mixing device is a rotating drum with bubble-catching blades and rotating mixing plates with apertures. The top of the vessel for these mixers may include a closed top and sterile filters.

PROBLEM TO BE SOLVED: To provide a bone cement system that is protected against clogging by cement powder. SOLUTION: The invention relates to the bone cement system having a mixing facility 10 for mixing and dispensing of bone cement, a reservoir container for a monomer, and a conveying means 122, whereby the mixing facility comprises a mixing cylinder; the mixing cylinder stores a bone cement powder; a sieve element is arranged between the reservoir container and the mixing facility in order to prevent ingress of the bone cement powder from the mixing cylinder into the conveying means; and the mixing device comprises a dispensing opening for dispensing a bone cement that is mixed from the bone cement powder and the monomer. The invention provides for the dispensing opening 23 to comprise a shield 1 having at least one through-opening 2, and a ratio of an area of the through-opening 2 to the area of the sieve element 4 to be at least 1 to 3, and a distance between the shield 1 and the sieve element 4 to be at least 1 mm.

PROBLEM TO BE SOLVED: To provide a device for preferably mixing water and gas for the purpose of producing drinking water containing gas with simple structure and producing at low cost. SOLUTION: The device joins water supplied from a water supply system 3 with gas supplied from a gas supply system 4 in a mixture section 2b, and introduces a generated mixture of the water and gas into a turbulence generator 2a wherein a plunger 11 having a flow connection part 16 vibrates in a housing 10 relatively to the housing for further mixing. The vibration movement is generated by an electromagnet, and the plunger is supported by a spring. COPYRIGHT: (C)2009,JPO&INPIT
