The present disclosure relates to a device for producing microbubble water by using a ultrasonic vibrator having a maximized amount of dissolved bubbles, a microbubble discharge unit, cell culture medium containing microbubble water and cell culturing method using the same, a high-efficiency mixed fuel using microbubble and apparatus for manufacturing the same.

A mixing chamber for mixing a variety of dry ingredients with a liquid is disclosed. The mixing chamber has an accumulation chamber that evenly distributes ingredients as they pass a liquid spray nozzle, resulting in uniform hydration. The liquid may be sprayed at a variety of pressures to achieve varying levels of granule hydration to permit the manufacture of dough, batter, or other compositions. Even dry ingredients which are generally slow to absorb moisture may be rapidly and evenly hydrated without an excess of liquid. Process parameters, such as volume flow rate of the dry ingredients, can also be varied.

A system for mixing fracturing gel includes a dry gel mixing chamber having a bladed impeller carried to rotate in the mixing chamber. The mixing chamber has a dry gel inlet and hydrating fluid inlet. A valve is fluidically coupled to the hydrating fluid inlet to automatically maintain a specified flow condition of hydrating fluid into the mixing chamber over multiple different values of the flow condition to the hydrating fluid inlet.

The invention relates to a valve device (50) for injecting gas (4) into a mixing chamber (11) of a plastic metering device (1) in order to load at least one component (2) located in the mixing chamber (11) with the gas, comprising a pressure regulating valve (51) and a flow regulator (52), wherein an inlet (56) of the pressure regulating valve (51) is connected to an outlet (55) of the flow regulator (51), and an outlet (71) of the pressure regulating valve (51) is suitable for opening preferably directly into the mixing chamber (11). The pressure regulating valve (51) has a valve chamber (57), an actuator (58) which can be moved in the valve chamber (57), and a piston unit (59) which is coupled to the actuator (58) and by means of which an axial position of the actuator (58) can be fixed on the basis of a pressure in the valve chamber (57). The invention additionally relates to a metering device (1) for metering out a foamed and foamable plastic (5) in a discontinuous manner, comprising such a valve device (50).

A method and apparatus for obtaining a product chemistry from a product and a fluid is provided. A product is housed within a dispenser. A fluid is introduced through a manifold diffuse member having a plurality of ports. A cover is positioned adjacent the manifold diffuse member and includes a plurality of ports. The cover is able to be adjusted, for example, by rotating the cover, to align and un-align the manifold diffuse ports and the cover ports. This adjustment controls the flow characteristics of the fluid through the manifold diffuse member and cover to control the characteristics of the fluid in contact with the product. The adjustment of the cover to control the flow will provide a generally consistent concentration and erosion rate based upon known relationships between a characteristic of the fluid and the flow of the fluid in relation to the product.

When a first electromagnetic valve of a first stirring tank is turned ON and a second electromagnetic valve of a second stirring tank is turned OFF, the air pressure inside the first stirring tank increases and the liquid in the first stirring tank is sent into the second stirring tank via piping. When the volume of the liquid inside the second stirring tank reaches an upper limit, the first electromagnetic valve of the first stirring tank is turned OFF and the second electromagnetic valve of the second stirring tank is turned ON. As a result, the liquid inside the second stirring tank is now sent into the first stirring tank via the piping. Ultimately, because the liquid is circulated between the first and second stirring tanks and the liquid is flowing at all times due to the repetition of said actions, separation does not occur.

A flow control arrangement for use with a pump in an aquarium includes a main body having an inlet flow conduit and an outlet flow conduit. The main body has a cylindrical wall having first and second opposite open ends and defining an open interior; and a through hole extending through the wall to the open interior. A flow control dial closes the first open end; and an aeration flow dial closes the second open end and is rotatably adjustable relative to the main body. The aeration flow dial has a tubular aeration wall extending into the open interior. The aeration wall has an aperture, wherein the aeration flow dial can be rotatably adjustable to control axial alignment of the aperture with the through hole in the wall of the main body to selectively adjust a size of a resulting orifice from the open interior of the main body to outside of the main body.

The invention relates to a plant for packaging a gas mixture in one container (10), comprising a source of a minor gas (1), a source of a carrier gas (2), a mixer device (3), a first transfer circuit (6) fluidically connecting the source of minor gas (1) to the mixer device (3) and comprising a first flow regulator device (4), a second transfer circuit (7) fluidically connecting the source of a carrier gas (2) to the mixer device (3), a delivery circuit (8) comprising a second flow regulator device (9), the first transfer circuit (6) and the second transfer circuit (7) each include an expansion member (15, 16), the second flow regulator device (9) comprising a pressure raising member (9), the first flow regulator device (4) comprising several regulator members.

A system for mixing fracturing gel includes a dry gel mixing chamber having a bladed impeller carried to rotate in the mixing chamber. The mixing chamber has a dry gel inlet and hydrating fluid inlet. A valve is fluidically coupled to the hydrating fluid inlet to automatically maintain a specified flow condition of hydrating fluid into the mixing chamber over multiple different values of the flow condition to the hydrating fluid inlet.

The method and an apparatus for improving the steam dryness of a steam injection boiler includes injecting wet saturated steam and gas into an oil layer together in a sealed way, after the dryness of the wet saturated steam at an outlet of the steam injection boiler is improved by a dryness raiser. The dryness raiser includes a combined spray head, a steam heating chamber, a combustion chamber, and a mixing chamber. The gas generated by the combustion chamber enters into the mixing chamber and is fully mixed with the steam from the steam injection boiler. The dryness of the wet saturated steam at the outlet of the steam injection boiler can be improved to 95%-100%, and the effects of improving steam enthalpy, replenishing stratum energy and enlarging the steam wave and size are realized, so as to heat up the oil layer more effectively, and improve heavy oil development.
