The present invention relates to methods and systems for producing a foamed adhesive. A method for foaming an adhesive includes feeding an adhesive from a supply storage tank to a pump, conveying the adhesive outputted by the pump through an adhesive flow meter, injecting an air into the adhesive once the adhesive travels through the adhesive flow meter, feeding a mixture of the adhesive and air to a static mixer, mixing the mixture homogeneously with the static mixer such that the adhesive is foamed, and transporting the foamed adhesive to a product storage tank.

A tap apparatus including a container coupling portion including a liquid inlet portion, a body portion, and a plug valve portion. The body portion included a liquid outlet portion, wherein the liquid outlet portion is in fluid communication with the liquid inlet portion of the container coupling portion. The plug valve portion is configured and arranged to be seated within the body portion, wherein the plug valve portion is configured and arranged to be moved relative to the body portion between an open position, in which a liquid is free to flow from the liquid inlet portion and out through the liquid outlet portion, and a closed position, in which liquid from the liquid inlet portion is prevented from flowing out through the liquid outlet portion. The body portion also includes a plurality of flow channels provided in an interior surface thereof.

The invention relates to an apparatus, system, and method for the bulk blending of dry component materials to produce a blended product mix. The apparatus utilizes a special construction that allows multiple bulk dry materials to be added simultaneously to create a blended mix compliant with a desired or specified mixture of cement components. The system is automated by use of a controller, and provides real-time data to a user as to rates and amounts of materials blended and delivered over time.

A system for gas impregnation of a liquid includes a container for holding a product ingredient, a first still liquid conduit for conveying a still product including the ingredient, a gas cylinder providing a gas conduit with a compressed gas such as Nitrogen. The system includes two or more pressure chambers each having a corresponding liquid fill valve to control the flow of a still product filling the pressure chamber, and a gas diffuser for diffusing the compressed gas into the still product to produce a gas infused product. A multi-way valve in fluid communication with each of the pressure chambers directs the gas infused product from a selected one of the pressure chambers to a first charged product conduit for supplying a charged liquid dispenser, and blocks fluid from flowing from other, non-selected, ones of the pressure chambers. A method for using the subject system is also provided.

There is provided a gas mixer arrangement comprising a first gas source for supplying a first gas; a second gas source for supplying a second gas different from said first gas; first and second flow regulation devices for regulating the respective flow of the first gas and second gases from the first and second gas sources; a mixer; and an outlet. The mixer is located downstream of the first and second flow regulation devices and arranged, in use, to mix the first and second gases to provide a mixed gas to the outlet. The gas mixer arrangement further comprises a meter comprising a first sensor assembly operable to determine the average molecular weight of the mixed gas and including a high-frequency planar piezoelectric crystal oscillator in contact with the mixed gas, a second sensor assembly operable to determine the pressure of the gas downstream of one of the first or second flow regulation devices, and a controller operable, in response to the average molecular weight of the mixed gas and said gas pressure, to control automatically said first and second flow regulation devices to control the relative proportion of the first and second gases in said mixed gas and the pressure or mass flow rate of the mixed gas from the outlet.

Embodiments include systems and methods of in-line mixing of hydrocarbon liquids from a plurality of tanks into a single pipeline. According to an embodiment, a method of admixing hydrocarbon liquids from a plurality of tanks into a single pipeline to provide in-line mixing thereof includes determining a ratio of a second fluid flow to a first fluid flow based on signals received from a tank flow meter in fluid communication with the second fluid flow and a booster flow meter in fluid communication with a blended fluid flow. The blended fluid flow includes a blended flow of the first fluid flow and the second fluid flow. The method further includes comparing the determined ratio to a pre-selected set point ratio thereby to determine a modified flow of the second fluid flow to drive the ratio toward the pre-selected set point ratio. The method further includes controlling a variable speed drive connected to a pump thereby to control the second fluid flow through the pump based on the determined modified flow, the pump being in fluid communication with the second fluid flow.

First and second concentration measurement parts (415, 425) are provided in first and second supply liquid lines (412, 422) in which first and second supply liquids flow, respectively. A dissolved concentration of gas in the second supply liquid is lower than that in the first supply liquid. In the first and second supply liquid lines, respective one ends of first and second branch lines (51, 52) are connected to respective positions on the upstream side of the concentration measurement parts. The other ends of the first and second branch lines are connected to a mixing part (57), and by mixing the first and second supply liquids, a processing liquid is generated. Respective flow rate adjustment parts (58) of the first and second branch lines are controlled on the basis of respective measured values of the first and second concentration measurement parts so that the dissolved concentration of the gas in the processing liquid can become a set value. It is thereby possible to prevent the supply liquid containing particles or the like caused by the concentration measurement part from being contained into the processing liquid to be supplied to a substrate and also to adjust the dissolved concentration of the gas in the processing liquid to the set value with high accuracy.

A system for blending polymers and other chemicals in an aqueous liquid is provided. Static mixers and tubes, preferably in one or more tube bundles, provide a volume sufficient to allow a residence time in the system to hydrate a polymer. Static mixers may be integrated with a tube bundle. The system may be mounted on a portable base such as a trailer. The concentration of polymer and chemicals in water may be controlled by a controller. A variable speed electric pump may be utilized to precisely control the amount of polymers or other chemicals added to the aqueous liquid.

A method for mixing at least two liquid components of a two- or multi-component wet coating system, wherein a feed component under a first hydraulic pressure set at constant is fed discontinuously through a variable passage cross-section to a parent component under a second hydraulic pressure set at constant. An actual feed quantity of the feed component is detected and the feed quantity of the feed component is regulated with respect to a target feed quantity for the feed component in such a way that a timing cycle of the discontinuous feed and the passage cross-section for the feed component are influenced.
