A system for providing a NO-containing gas flow to treat a biological object. The system includes a nozzle receptacle for receiving NO-rich air from a plasma-generated NO source, tubing coupled to the nozzle for directing the NO-rich air to a scrubber, the scrubber configured to receive a solvent for absorbing NO2, tubing coupled between the scrubber and a gas mixer for directing scrubbed NO-rich air to the gas mixer, where the gas mixer is coupled to a source of atmospheric air for selectively mixing the scrubbed NO-rich air with the atmospheric air to create diluted NO-containing air; and a manifold for distributing the diluted NO-containing air to a plurality of patient locations.

A mixing vessel comprises a top portion (12) on an inverted conical middle portion (14) and a mixing chamber (16) below the middle portion. A launder (28) surrounds the upper part of the top portion. Solution from the launder is led to a vertical pipe (46) including a motor driven impeller (42) down to the level of the mixing chamber. Two vertically spaced feed pipes (46, 48) lead from the vertical pipe to enter the mixing chamber tangentially in opposite directions.

A mixer and a method therein, including feeding a rotating flow of exhaust gas in a mixing pipe towards a turning end of a mixing chamber; dosing reactant by a doser against the rotating flow around a centreline of the mixing pipe; maintaining a guide around the doser such that a front face of the guide faces the rotating flow, and the guide defines a central opening surrounding the doser; guiding a side flow out of the rotating flow to a carrier flow around the doser via the central opening; and inhibiting by the guide turbulence from being transferred from the side flow to the carrier flow.

The present invention is a novel bubble generator that can be used in many different industrial applications. The design of the bubble generator of the invention allows its user to selectively generate gas bubbles in a liquid having a wide range of diameters in the range from microns to millimeters simply by changing the ratio of the flow rate of the gas to that of the liquid. The bubbles are generated at low liquid and gas supply pressure values. The bubble generator of the invention is able to create an unstable liquid flow regime having large amplitudes and frequencies for liquid containing bubbles without the use of moving mechanical parts and drives.

A wine aeration device and methods of aerating wine that draw wine from the bottom ⅓ of the container into an aeration chamber where the wine undergoes a first phase of aeration. The wine continues through a return tube into the container where it undergoes a second phase of aeration by way of multiple slits in the return tube causing a venturi effect on the flowing wine.
