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.

A pressurized container assembly includes a pressurized container, a valve, and a shearing chamber. A flowable product and propellant are also provided within the container. The propellant is substantially non-soluble in the flowable product. Methods of producing a foamed flowable product using shearing chambers are also disclosed.

A system includes a plurality of static mixers. Each static mixer has an internal cylinder defining a central orifice for passage of the multi-phase fluid. The internal cylinder has an inlet side and an outlet side. The inlet side of the internal cylinder has a plurality of inlet channels, and the outlet side of the internal cylinder has a plurality of outlet channels. The multi-phase fluid enters the inlet side to be mixed in the central orifice and is expelled through the outlet side. The plurality of static mixers are fixedly disposed along the pipeline at a predetermined number of locations, spaced a predetermined distance apart, to mix the multi-phase fluid and prevent formation of the adverse flow regimes.

Provided is a ultrafine bubble generating apparatus capable, when generating nanobubbles in a liquid, of appropriately mixing a gas into a liquid ejected from a liquid ejector. The ultrafine bubble generating apparatus comprises a liquid ejector for ejecting a liquid, a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector, and an ultrafine bubble generator for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. Between the liquid ejector and the ultrafine bubble generator, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the ultrafine bubble generator.

The invention provides a microdroplet- or bubble-producing device that does not require separate through-holes for different liquid droplet/air bubble-producing flow channels. The droplet-producing flow channels are configured in a three-dimensional manner unlike in a conventional device where they are configured in a two-dimensional plane, and therefore the flow channels can be provided in a more high-density configuration than the prior art. In the microdroplet/bubble-producing device comprising slit(s) and the row of the plurality of microflow channels, the slit(s) is/are a continuous phase supply slit, a dispersion phase supply slit and a discharge slit, the plurality of microflow channels are configured so that the ends of the slit(s) and the two supply ports on both sides or the supply port and discharge port on either side are mutually connected, and at the sites of connection between the microflow channels and the slit(s), the dispersion phase undergoes shear with the continuous phase flow as the driving force, producing droplets or air bubbles of the dispersion phase, which are recovered from the discharge port.

The invention relates to a process for the production of an elastomer agglomerate composition, comprising: forcing a slurry through an aperture in a valve assembly (1) to obtain the elastomer agglomerate composition; wherein the valve assembly (1) comprises the valve (2) and a seat (3) that are arranged opposite each other to provide a flow channel for the slurry to be homogenized with an emulsifying channel section (5) that is provided with the aperture; wherein the emulsifying flow channel section is arranged at an angle (a) with respect to an axial center line of the valve in a cross sectional view of the valve assembly; and wherein the slurry comprises elastomeric particles in water.

A fluid supply pipe comprises a tubular body and an internal structure. The tubular body has an inlet through which a fluid flows in and an outlet through which the fluid flows out, and is of a hollow shape having an inner wall surface of a circular cross section. The internal structure is a prismatic shaft having a plurality of lateral faces configured to be housed in and fixed to the tubular body. A plurality of pillars are arranged in a mesh pattern on the lateral faces. A space formed between the plurality of pillars between the lateral faces of the internal structure and the inner wall surface of the tubular body serves as fluid flow paths, and the fluid is given a flow characteristic by passing through the flow paths between the plurality of pillars while the fluid is supplied from the inlet and flows out of the outlet.
