A method and system for diluting and activating polymeric materials are also disclosed.

A nozzle flow stirring pipe includes a pipe body and a nozzle. The pipe body is cylindrical and includes an inner pipe member and an outer pipe member. The inner pipe member has a liquid-extracting channel. The outer pipe member fits around the inner pipe member. A reflow channel is defined between an inner wall of the outer pipe member and an outer wall of the inner pipe member. The nozzle is disposed at one end of the pipe body. The inner pipe member is penetratingly disposed at the nozzle and exposed from below. The nozzle has a plurality of liquid-ejecting pores in communication with one end of the reflow channel.

A hydrogen molecule remixing device includes a base (10), a first gas and water channelling disc (30), an anode (40), a cathode (60), an ion membrane (50), a second gas and water channelling disc (70), a cover (80), a cationic water outlet connector (85) and a connector (90). In practice, the source water is electrolyzed in the anode cavities of the anode to form oxygen molecules, ozone and anionic water, and electrolyzed in the cathode cavities of the cathode to form hydrogen molecules and cationic water. The hydrogen molecules are carried by the cationic water into the collecting and guiding chambers of the second gas and water channelling disc, so that the hydrogen molecules and the cationic water produce an blending reaction, and more hydrogen molecules are dissolved into the cationic water.

The present invention relates to articles comprising a plurality of molded hollow parts having different central axis through the hollow elements further having passages in walls of the hollow parts transverse to the central axis of the hollow parts. The present invention also relates to methods of applying two part curable materials to substrates using the molded parts of the invention as mixing elements.

An aftertreatment system includes a filter configured to receive an exhaust gas and a selective catalytic reduction (SCR) system configured to treat the exhaust gas. A body mixer is disposed downstream of the filter and upstream of the SCR system. The body mixer includes a housing defining an internal volume and including at least a first passageway, a second passageway, and a third passageway. The first passageway receives a flow of the exhaust gas from the filter and directs the flow of the exhaust gas towards the second passageway. The second passageway redirects the flow in a second direction opposite the first direction towards the third passageway. The third passageway redirects the flow in a third direction opposite the second direction towards the SCR system. An injection port is disposed on a sidewall of the housing and configured to communicate an exhaust reductant into the internal volume.

The present invention relates to articles comprising a plurality of molded hollow parts (11) having different central axis (14, 15) through the hollow elements, further having passages in walls of the hollow parts transverse to the central axis of the hollow parts. The present invention also relates to methods applying two part curable materials to substrates using the molded parts of the invention as mixing elements.

A handheld device for mixing a liquid and a gas to form foam before a treatment procedure comprises: an inlet for letting a liquid enter the device, the inlet adapted for attachment to a syringe containing the liquid, an outlet for letting a formed foam exit the device, a chamber containing a gas, the chamber comprising the inlet and outlet, at least one agitation element disposed in the chamber, the at least one agitation element is arranged for independent movement in at least one degree of freedom, the at least one agitation element sized and shaped to mechanically agitate liquid flowing past the at least one agitation element, the liquid flowing in an overall inlet-to-outlet direction, the agitation being sufficient for the at least some of the liquid to mix with the gas to produce the formed foam; the device is dimensioned for holding in one hand.

A formula delivery appliance generally includes a formula delivery head having features to mix, direct, and distribute formulation through nozzles to a desired location, such as the hair or scalp of a user. In this regard, the formula delivery head may include a plurality of nozzles configured to discharge the formulation at a desired flow rate. In some instances, the flow rate across the plurality of nozzles is controlled such that each nozzle has a flow rate within a specified percentage of the average flow rate across the plurality of nozzles.

An aftertreatment system includes a filter configured to receive an exhaust gas and a selective catalytic reduction (SCR) system configured to treat the exhaust gas. A body mixer is disposed downstream of the filter and upstream of the SCR system. The body mixer includes a housing defining an internal volume and including at least a first passageway, a second passageway, and a third passageway. The first passageway receives a flow of the exhaust gas from the filter and directs the flow of the exhaust gas towards the second passageway. The second passageway redirects the flow in a second direction opposite the first direction towards the third passageway. The third passageway redirects the flow in a third direction opposite the second direction towards the SCR system. An injection port is disposed on a sidewall of the housing and configured to communicate an exhaust reductant into the internal volume.

A homogenizing apparatus (1) comprising: an inlet (2) for receiving a pressurized fluid, possibly also containing solid particles; a zone wherein homogenization of the fluid takes place; an outlet (10) for the fluid at a lower pressure with respect to the inlet pressure, wherein, in the homogenization zone, the fluid passes from a zone having a larger diameter (or volume) to a zone having a smaller diameter (or volume), the homogenization zone comprising an interacting element (9) shared by a first stage (equipped with a first deflector plug (6)) and a second stage suitable for creating back pressure (equipped with a second deflector plug (12)), where the deflector plugs (6 and 12) operate with the interacting element (9) they share, generating an increase in the shear rate within the first stage. The invention also concerns a homogenization process.
