A dynamic mixer dispense valve and metering apparatus suitable for use in mixing and applying high viscosity, disparate viscosity, high ratio and/or relatively immiscible two part compounds that exhibit short cure times includes a housing supporting a pair of valve assemblies each coupled to respective sources of base and accelerator components. A pair of pneumatic valve actuator s control the operation of the valve assemblies to control the flow of components into a mixing chamber. Within the mixing chamber a mixer impeller is rotatably supported and coupled to a source of rotational power. An additional pneumatic valve actuator combination operates a further flow control to prevent undesired material loss following a shot cycle.

A contactor having a contactor gas inlet and a contactor gas outlet and a first supply of gas connected to the accumulator gas inlet. A second supply of gas connected to the contactor gas inlet and a supply of liquid connected to the accumulator liquid inlet. A first valve disposed between the first supply of gas and the accumulator gas inlet, a second valve connected to the accumulator gas outlet, a third valve disposed between the supply of liquid and the accumulator liquid inlet, a fourth valve disposed between the contactor gas inlet and the second supply of gas; and a fifth valve connected to the contactor gas outlet.

A dispensing assembly for cold beverages comprises 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 portable bubble water bottle of the present application includes a first space, a second space, an one-way gas valve and a gas cylinder. The second space is located in the first space along the first projection direction. The one-way gas valve connects the first space with the second space. The gas cylinder is located in the second space, and has a gas outlet connected to the one-way gas valve.

Provided is a gas-dissolved water generating apparatus in which a pressure pump and a multi-stage mixer are sequentially arranged on at least one conduit; a circulation pipe connecting an inlet side of the pressure pump and a outlet side of the pressure pump is positioned on the conduit; a gas supply unit for supplying a predetermined external gas to one side of the circulation pipe, which is connected to the inlet side of the pressure pump, via a gas supply pipe; the gas supply unit and the circulation pipe are connected through a three-way valve, and the three-way valve is configured to have a structure of a venturi pipe having wide inlet and outlet channels and a narrow interior channel along the circulation pipe, so that a gas supplied from the gas supply unit is independently sucked.

A resistivity adjustment device includes: a hollow fiber membrane module that is divided by a hollow fiber membrane into a liquid phase side area; a liquid supply pipe that communicates with the liquid phase side area; a liquid discharge pipe that communicates with the liquid phase side area; a gas supply pipe that communicates with the gas phase side area; a gas discharge pipe that communicates with the gas phase side area; a bypass pipe that communicates with the liquid supply pipe and the liquid discharge pipe to bypass the hollow fiber membrane module; and a first on-off valve that is connected to the gas discharge pipe and opens or closes a first passage inside the gas discharge pipe, wherein the first on-off valve opens the first passage to discharge water accumulated in the gas phase side area.

A technique is provided for incorporating pneumatic control in centrifugal microfluidics. The technique involves providing a chip controller that has pressurized fluid supply lines for coupling one or more pressurized chambers of the controller with ports of a microfluidic chip. At least part of the chip controller is mounted to a centrifuge for rotation with the chip. A flow control device is provided in each supply line for selectively controlling the pressurized fluid supply, and is electrically controlled. Bubble mixing, on and off-chip valving, and switching are demonstrated.

A mineral spring generator has a machine body and a pipeline disposed in the machine body. Two ends of the pipeline respectively have a water inlet and a water outlet. A solenoid valve is connected between the pipeline. At least two injection channels are connected to the pipeline at intervals along a direction of a water flow in the pipeline. A micromotor is connected between each of the at least two injection channels. An outer end of each of the at least two injection channels is connected to a material container. Each material container is adapted to be filled with a liquid mineral spring concentrate. When the present invention is used, water is inputted through the water inlet, and the solenoid valve and the micromotors are activated to add the mineral spring concentrates in the at least two material containers to different positions of the pipeline.

Disclosed herein are techniques and methods for dispersing a volume of gas in a beverage contained in an unpressurized container.
