The present patent application relates to a method for producing dispersions and nanodispersions of graphite, graphene and amorphous carbon in aqueous media without using any surfactant and without requiring any chemical modification of the graphene, such as oxidation to produce graphene oxide.

The invention relates to continuous methods for compounding and applying adhesives, characterized in that (i) a base component of the adhesive is mixed continuously with at least one aggregate so as to produce a compounded adhesive; and (ii) the adhesive compounded in this manner is applied to a substrate. The invention also relates to such methods where a device as described here is used to carry out the method.

A device for mixing at least two fluid to pasty substances has a housing (2) with at least two openings (5, 6) for feeding the substances and with a discharge opening (8), a mixing element (3) which can rotate in the housing (2), which mixing element (3) can be displaced in the direction (17) of its axis (7) in relation to the housing (2) in order to adjust the size of a gap (18) between a conically tapering part (14) of the mixing element (3) and a likewise tapering region (15) of the housing (2) in order to adjust the shear rate in the region of the gap (18). The mixing element (3) has a region (9) in which annular ribs (11) are provided which project from the mixing element (3) and which engage between adjacent annular ribs (12) which project from the inner surface (10) of the housing (2).

A nozzle flush adapter includes an externally threaded coupler configured to threadably engage and secure a mixer nozzle in a fluid tight coupling together with a hose receiving coupler having an internal thread configured to engage and secure the threaded end of a conventional water hose in a fluid tight coupling. The nozzle flush adapter facilitates cleaning and reuse of normally disposable mixer nozzles exposed to two-component epoxy adhesives and the like by allowing the user to exercise a method whereby the user is able to flush water under pressure through the mixer nozzle before the material has cured.

A mixer for mixing two materials includes a casing and a mixing component. The mixing component has a first vertical wall, a second vertical wall in parallel to the first vertical wall, an inlet baffle, an outlet baffle, a plurality of first arc shape guiding plates and a plurality of second arc shape guiding plates. The inlet baffle and the outlet baffle are disposed on the two ends of the first and second vertical walls, respectively. The first arc shape guiding plates and second arc shape guiding plates are disposed between the inlet and outlet baffles, and the first and second arc shape guiding plates are mutually spaced and disposed in opposite to each other. The two materials are imported from the inlet baffle and guided to flow through the first and second arc shape guiding plates, and subsequently mixed and exported from the outlet baffle.

A base valve, a base pump, a catalyst valve, a catalyst pump, a mixing chamber, a base cylinder connected to the base valve, and a catalyst cylinder connected to the catalyst valve. The base and catalyst cylinders are actuated so as to push base and catalyst fluids out of the base and catalyst cylinders, respectively, and into the mixing chamber. An electronic controller has a ready mode and a dispensing mode. In the ready mode, the controller i) activates the base and catalyst pumps and ii) signals the actuator to push or pull, in response to a dispense signal being asserted. In the dispensing mode, the controller a) deactivates the base and catalyst pumps, b) signals the actuator to stop pushing or stop pulling, and maintains a) and b) in response to the dispense signal being de-asserted. Other embodiments are also described.

Multi-component fluid mixing devices and methods of manufacturing and using such multi-component fluid mixing devices are provided. The multi-component fluid mixing devices include one or both of a serpentine flow path and an attachment point decoupled from an inlet of the multi-component fluid mixing devices. The method of use includes switching between multi-component fluid mixing devices with different length flow paths, while retaining a constant position of the outlet of the multi-component fluid mixing devices. A manufacturing method includes fusing two halves of a multi-component fluid mixing device together with mixing elements in a serpentine flow path captured in a mixer wall formed between the two halves of the multi-component fluid mixing device.

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.

The invention relates to a foaming device (1) which has a foaming unit (2) with a foaming chamber (17), said foaming chamber comprising mechanical foaming means (15, 19) which are contained inside the chamber and by means of which at least three components that are fed to the foaming chamber (17) can be mixed. At least one adhesive, a gaseous foaming medium, and a free flowing diluent are used as the components in order to produce an adhesive foam. Adjusting means (25) are provided in order to adjust the ratio of the individual components to one another in order to influence the properties of the adhesive foam.

In a method for mixing two liquid components of a medium with the aid of a static mixer, the two components are supplied to the static mixer, are mixed therein and are subsequently dispensed from the mixer. In this respect, only one respective component is supplied to the mixer, while the other component is not supplied to the mixer.
