In a method for infusing a gas from a gas source into a liquid beverage, liquid beverage is driven from a beverage container into a liquid inlet port of a venturi mixing device. Nitrogen is infused into the liquid beverage by driving nitrogen through a gas inlet port of the venturi mixing device, thereby delivering nitrogen-infused liquid beverage to a discharge port of the venturi mixing device. The nitrogen-infused liquid beverage is poured from the discharge port through a faucet.

A Venturi device with a primary flow path and a secondary flow path introduced into the primary flow path, wherein a flow of one or more flowable mediums in the primary flow path and the secondary flow path creates a vortex generating a suction at an inlet of the Venturi device. A particulate burner system can be used to combust fuel emission byproducts by injecting fuel and air into a housing having a bottom plate with a round bottom opening for burners to inject fuel into a combustion chamber and a top plate with a round top opening for exhausting fuel emissions. A thruster system can be used to propel munition for deep earth penetration by using a thruster system having a transfer cone connected to a munition body.

To generate homogenized super-micro bubbles of nano-scale in a simple structure and at a low cost, a super-micro bubble generator has a cylindrical casing provided with an opening for the introduction of a liquid at one end and an outlet for delivery of the liquid at the other end, and the cylindrical casing includes: a flow speed increasing part for increasing the flow speed of the liquid introduced from the introduction opening; a gas suction part for drawing gas from the outside into the casing, wherein the pressure is decreased by a liquid flow whose flow speed is increased in the flow speed increasing part; and a super-micro bubble-containing liquid producing part for shearing, by the liquid flow whose flow speed is increased in the flow speed increasing part, the gas that is sucked by the gas suction part and generating a liquid including super-micro bubbles, in this order, from the introduction opening to the delivery opening.

There is provided a loop flow type bubble generation nozzle capable of improving the bubble generation efficiency compared to conventional nozzles without reducing the bubble generation efficiency even when liquid containing impurities is used. A loop flow type bubble generation nozzle 10 includes a tubular bottomed member 1 having a circular cross section and a tubular member 2 which is fitted into the other end side of the bottomed member 1. A substantially cylindrical space surrounded by the bottomed member 1 and the tubular member 2 serves as a loop flow type gas-liquid stirring and mixing chamber 6. The tubular member 2 has, on the center thereof, an inflow hole 7 which is capable of allowing liquid and gas to flow therein, and a first jet hole 8a and a second jet hole 8b which are capable of jetting liquid and gas. The inflow hole 7 is formed in a tapered shape whose diameter continuously expands from the first jet hole 8a toward the loop flow type gas-liquid stirring and mixing chamber 6. A plurality of cut-away parts 7a are formed on an end face of the inflow hole 7, the end face facing the loop flow type gas-liquid stirring and mixing chamber 6.

A device for frothing a liquid includes a tube-shaped housing with an inner surface having a curved periphery. At least one inlet is arranged in a lateral area of the housing for letting in the liquid and a frothing gas, and may have a tangential orientation with respect to the curved periphery of the inner surface of the housing. End faces of the housing are open and function as outlets of the device, where a longitudinal axis of the housing may extend in a horizontal direction. Rings may be provided inside the housing for keeping a rotating flow inside the housing during a period of time which is sufficiently long for a frothing process to take place in an effective manner.

An aerating and liquid agitating device to efficiently introduce high velocity, agitating air into a water line for mixing and aerating water tanks. An illustrative embodiment of the aerating and liquid agitating device includes a device fitting having an ingress end configured to be coupled to a liquid pump, an egress end and an opening between the ingress end and the egress end. The device fitting may be configured to accommodate flow of a liquid from the ingress end to the egress end. An air inlet fitting may extend through the opening in the device fitting and terminate inside the device fitting. The air inlet fitting may be defined by a terminal angled profile sloped between from about 35 to about 90. An air inlet hose may be coupled to the air inlet fitting. The air inlet hose may be configured to introduce air through the air inlet fitting into the device fitting.
