An extrusion equipment adapted for supercritical foaming and mixing of a raw material includes a mixing unit, an injection unit for injection of supercritical fluid into the mixing unit, and an extrusion unit for extrusion of the raw material. The mixing unit includes a tube for input of the raw material, and a propelling screw rod and an auxiliary screw rod that are disposed side by side in the tube and that cooperatively compress and propel the raw material. The auxiliary screw rod rotates at a speed at least twice that of the propelling screw rod and in a direction opposite to that of the propelling screw rod.

Embodiments described herein include an apparatus for use in a bathtub containing water. The apparatus includes an outer shell, a soap holder, configured to hold a liquid soap, at least one set of blades, and a motor disposed within the outer shell and coupled to the set of blades. The motor is configured to form soap bubbles by spinning the set of blades such that the blades lift the water from the bathtub, and pass the lifted water, together with liquid soap from the soap holder, through air. Other embodiments are also described.

A device for the processing of liquids and/or solids comprises a disposable layer adapted to shield a working surface from coming into contact with, and being fouled by, the processed liquids and/or solids, and apparatus suitable to apply a negative pressure in a gap between said disposable layer and said working surface, thereby causing said disposable layer to adhere to said working surface.

Pumping and foaming device (100) comprising a pumping and foaming unit (102) rotatable around a shaft (130) by driving means (104), the pumping and foaming unit (102) comprising a pumping element (110) whose rotation pumps both air and fluid and mixes them; the pumping and foaming unit (102) further comprising a foaming element (120) whose relative rotation in a foaming chamber (121) drives the mixture of air and fluid coming from the pumping element (110) under a certain level of shear stress which allows this mixture to be foamed.

Methods and apparatuses for producing a substrate are described. A method and apparatus for introducing a component into a fluid supply is also presented. A method can include providing a first fluid supply. The fluid supply can be configured as a foam in some embodiments. The method can also include providing a component feed system and a supply of the component. The method can include introducing the component to a fluid supply in an eductor in some aspects. A resultant slurry including a fluid supply and the component can be transferred through a headbox. The resultant slurry can be dewatered to provide a substrate including the component.

A blade assembly for a blending system is shown and described. The blade assembly may include apertures formed through a body. The body may include paddles extending from the body. The blade assembly may be rotated to force a fluid through the apertures. The fluid may be frothed by the apertures.

The invention refers to a pumping and foaming device (10) comprising a mixing unit (201) where air and a foamable fluid are conveyed and pre-mixed, and a foaming unit (203) where the mixture of air and fluid is foamed; the device (10) further comprising a processing element (202) rotatable with respect to the foaming unit (203), such that the rotation of the processing element (202) sucks air and fluid by centrifugal forces into the mixing unit (201), where they are conveyed and pre-mixed, that same rotation of the processing element (202) with respect to the foaming unit (203) driving the mixture of air and fluid under a certain level of shear stress which allows the mixture to be foamed. The invention further refers to a pack (100) comprising a device (10) and a fluid container (20), and further to a machine (200) to which such a pack (100) is connectable. The invention also refers to a system (300) comprising a machine (200) and a pack (100).

The invention relates generally to waste exhaust energy recovery and, in particular, a system or a retrofit kit for generating cavitation including a cantilevered bearing arrangement. The system may include a turbine wheel configured to drive an input shaft in response to exhaust energy. The input shaft may further support a cavitation impeller for generating pressure, fluid flow, and cavitation within a fluid. Upon collapsing, the cavitation bubbles may release energy that is captured by an output turbine mounted on an output shaft. Output shaft may harness the captured energy, which may be transmitted to an output device to, for example, turn a crankshaft to add torque or operate a generator to charge an external power source, such as a battery. Additionally, the system facilitates reducing emissions and fuel consumption while also supporting enhanced performance.

Disclosed is a mixing device (1) for mixing a first component (2) with a second component (3) for providing a foamed or foamable plastic (5), comprising a mixing chamber (11), a stirrer (30) that is arranged in the mixing chamber (11) and can be rotated about an axis of rotation (31), a first inlet opening (13) for the supply of the first component (2) into the mixing chamber (11), a second inlet opening (14) for the supply of the second component (3) into the mixing chamber (11), wherein the first inlet opening (13) has an axial spacing from the second inlet opening (14), and an outlet opening (16) for the exit of the plastic (5) from the mixing chamber (11).

The present disclosure relates to a container for the production of a foamed sclerosant composition, to kits and systems including such a container, to methods for preparing a foamed sclerosant composition using such containers, and to foamed sclerosant compositions obtainable by such methods. In an aspect, the container comprises a sealed sterile container body having one or more sidewalls extending between a top and a bottom of the container body and defining a foaming space. The container further comprises a mixing element disposed in the container body. The container contains a previously introduced gas and liquid sclerosant composition. The mixing element is configured to be operatively coupled with a rotatable actuator without the actuator reaching the foaming space. A medical professional may select the appropriate quantity and concentration for every treatment.
