An apparatus and method for delivery of fluids, particularly biological, reactive fluids. The apparatus provides an opening when force is acted on the apparatus, and closure when no force is acted thereon. The apparatus provides a cleaning mechanism to remove fluids and other materials from a mixing space after use.

A nanobubble-producing apparatus includes a liquid vat provided with a bubble-containing-liquid inlet in an upper part thereof and a bubble-containing-liquid outlet in a bottom part thereof, a microbubble-containing-liquid supply unit to supply microbubble-containing liquid that contains microbubbles to the bubble-containing-liquid inlet of the liquid vat, an ultrasonic collapse unit to radiate ultrasonic waves to the inside of the liquid vat so that an ultrasonic collapse field in which the collapsing of the microbubbles with the ultrasonic waves is concentrated and nanobubbles are generated is formed at a location where the microbubble-containing liquid supplied into the liquid vat through the bubble-containing-liquid inlet flows downward, and a nanobubble-containing-liquid extraction portion where the nanobubble-containing liquid that contains the nanobubbles generated by the ultrasonic collapse unit is taken out of the liquid vat through the bubble-containing-liquid outlet.

A spray proportioner hose includes an inner diameter that extends along a longitudinal length of the hose and through which a flow of spray component from a spray proportioner unit may be directed toward a fluid manifold of an applicator gun. At the fluid manifold, the spray component will be mixed with another spray component in a desired proportion. The hose includes a static mixer positioned within its inner diameter to interact with and thereby mix the flowed spray component within the inner diameter of the hose before the spray component is delivered to the fluid manifold.

The present invention claims a vortex gas-liquid apparatus for dissolving a gas or combination of gases in liquid to obtain a gas-liquid solution. The gas-liquid solution is obtained in a mixing chamber in the center of which a flow swirler is arranged to activate stirring and improve gas absorption by the liquid. The most effective use of the apparatus seems to be for dissolving hydrogen in petroleum products, such as gasoline or diesel fuel, and transporting them through main pipelines under pressure. Transportation of hydrogen in a state of solution in petroleum fuel will eliminate diffusion losses through the pipe walls or measuring devices along the pipeline.

A static mixer for liquids or gases includes a housing having a continuous inner surface defining a fluid flow path for liquids or gases, an inlet to the fluid flow path, and an outlet from the fluid flow path, and an insert extending longitudinally through the fluid flow path between the inlet and the outlet. The insert is elastically expansive to exert outwardly directed pressure against the continuous inner surface of the housing. In one embodiment, the insert is hollow and has deflectors dispersed therethroughout and each projecting inwardly into the fluid flow path. In another embodiment, the insert includes a helical deflector extending inwardly into the fluid flow path from the continuous inner surface, and helically about a longitudinal axis of the housing.

An actuating mechanism for a dual pump dispensing system comprises an actuator housing, a semi-spiral insert and optionally, a mesh screen (3). The actuating mechanism is intended to mix viscous products that flow under the forces achieved in mechanical pump dispensers of the types used in the cosmetic and personal care fields.
