A dispensing assembly for cold beverages includes a beverage supply conduit, an opening and closing tap for closing or opening the beverage supply conduit, a beverage dispensing conduit delimiting a fluid passage, a dispensing outlet arranged at the end of the dispensing conduit, an air supply conduit delimiting an air passage. The tap is directly connected to the dispensing outlet by providing a connecting coupling which connects the air supply conduit to the beverage dispensing conduit, the beverage dispensing conduit comprising a Venturi segment between the tap and the outlet in which, by flowing through the Venturi segment, the fluid passage reduces the cross section thereof and then increases the cross section thereof as in a Venturi conduit. An air passage regulating valve is provided in said air supply conduit for regulating the width of the air passage.

A fragrance dispensing system includes a first and a second container each having a main tube for the expulsion of a fragrance contained therein, and a dispensing device that provides a dispensing path towards an outlet section and that includes a mixing chamber and a first and second auxiliary tubes connected at one end to the mixing chamber. A containing case forms a seat containing the first and second containers, and a cap is configured to be applied on the containing case and houses the mixing chamber, an outlet section for the mixed fragrances and, at least partly, and the first and second auxiliary tubes, each of which has a free end separably connected to one of the main tubes when the cap is engaged to the case.

A liquid hydrogen store including a cryostatic container for holding the liquid hydrogen, a discharge line for discharge of gaseous hydrogen, a boil-off management system, a boil-off valve in the discharge line for selective opening and closing of a fluidic connection of the discharge line to the boil-off management system, a heat transport line, and one or more thermal contact members to establish thermal contact of the heat transport line with the boil-off management system.

An aquaculture system (1) for farming aquatic organisms includes an apparatus (2) for supplying oxygenated water into an enclosure (20) in which aquatic organisms are to be fanned. The apparatus (2) includes a water inlet (4) and an oxygen inlet (6) to create a water and oxygen mixture. The apparatus (2) also includes a venturi (17) arranged to dissolve the oxygen into the water passing through the venturi and such that the oxygen and water mixture passing through the venturi (17) is exposed to a substantially null magnetic field. The apparatus is also arranged such that the water and oxygen mixture that is supplied to the venturi (17) contains substantially no colloidal minerals. The apparatus also includes an outlet (18) for the oxygenated water in fluid communication with, and downstream of, the venturi (17) and in fluid communication with the inlet of the enclosure (20).

A system for meat processing may include: a conveyor configured to transport animal carcasses or portions of meat through a meat processing facility; and a spray system configured to spray each of the animal carcasses or portions of meat with aqueous ozone when each of the animal carcasses or portions of meat is transported to the spray system by the conveyor. The system may further include a second spray system configured to spray each of the animal carcasses or portions of meat with lactic acid or citric acid when each of the animal carcasses or portions of meat is transported to the second spray system by the conveyor.

A mixer for a vehicle exhaust gas system includes a mixer housing defining an internal cavity and having a mixer inlet configured to receive exhaust gas and a mixer outlet to direct exhaust gas to downstream exhaust components. A flow device is configured to receive the exhaust gas from the mixer inlet and to facilitate mixing of the exhaust gas and a reductant introduced into the first flow device. The flow device comprises a Venturi body centered on a body center axis, and the Venturi body comprises a body inlet configured to receive the exhaust gas from the mixer inlet and a body outlet configured to provide the exhaust gas to the mixer outlet. The Venturi body also includes a louver extending from an internal surface of the mixer housing to a distal edge that is downstream of the body outlet. An upstream vane is positioned within the Venturi body proximate the body inlet and is coupled to an upstream vane hub that is centered on an upstream vane hub axis. A downstream vane is positioned within the Venturi body proximate the body outlet and is coupled to a downstream vane hub that is centered on a downstream vane hub axis. The upstream vane hub axis is radially offset from the body center axis by an offset distance and/or the downstream vane hub axis is radially offset from the body center axis by an offset distance.

A first solution is mixed and diluted with diluting liquid to make a first dilute solution, a second solution is mixed and diluted with diluting liquid to make a second dilute solution, and the first dilute solution and second dilute solution, both diluted with diluting liquid, are mixed in a sealed tank.

An aerator has a submersible mixing tube having a water inlet and an aerated water outlet. An aspirating tube penetrates the mixing tube between the water inlet and the aerated water outlet, the aspirating tube having an air outlet introducing air into the mixing tube and an air inlet drawing in air from atmosphere above a water surface. The mixing tube has an outboard motor lower unit engagement to engage a lower unit of an outboard motor in use such that a propeller thereof locates entirely within the mixing tube with a midsection of the outboard motor extending from the engagement. As such, the propeller of the outboard motor lower unit thrusts water past the air inlet thereby creating suction at the inlet to draw air via the mixing tube to mix with the water to expel a plume of aerated water.
