A dispensing device is provided that has a nozzle that can mix together liquid reactants to dispense an expandable foam substance through concrete structures. The device features a liquid storage portion, a mixing portion and a dispensing portion. The storage portion includes liquid storage chambers in communication with a liquid passageway. The mixing portion has a mixing tube and a static mixer. The mixing tube has an elongated body with an interior passageway between opposing first and second ends. The static mixer is housed within the interior passageway of the mixing tube and features a plurality of curved baffles. The dispensing portion has a reservoir and a nozzle tip. The reservoir features a first end secured to the mixing tube and a second end communicating with a nozzle tip. The nozzle tip features a plurality of tine segments with each segment having a distal tip with an external gripping flange.

The present disclosure relates to a mixing assembly for a fluid mixing system. The mixing assembly includes a first rotational assembly having a first casing and a first hub rotatably mounted to the first casing, a second rotational assembly having a second casing and a second hub rotatably mounted to the second casing, an elongated member having a first end coupled with the first hub and an opposing second end coupled with the second hub, and one or more impellers secured to the elongated member.

A system for receiving a single-use vessel containing a mixing device has a support structure adapted to receive the single-use vessel and a drive-unit adapted to power, to control, or to power and control a mixing of contents of the single-use vessel when the single-use vessel is arranged in the support structure. The support structure and the drive-unit are provided as separate components that may be arranged both in an operating position, where the drive-unit is connectable to the mixing device of the single-use bag in the support structure, and in a separated position, where the drive-unit is separated from the support structure. The drive-unit comprises a tag reader that, in the operating position, is arranged to read a vessel tag of the single-use vessel arranged in the support structure.

Provided are systems, methods, and apparatuses directed to a container for storing a liquid, the container including a textured surface configured to increase the liquid's dissolved oxygen content, the textured surface having fluid-obstructions configured to disrupt a flow of the liquid in at least one direction, said disruptions being effective to decrease a surface tension associated with the liquid and increasing a surface area associated with the liquid.

A fluid mixing system includes a flexible bag having an interior surface bounding a compartment. A retainer is coupled to the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag. An elongated tubular connector has a first end coupled to the flexible bag and an opposing second end projecting into the compartment thereof. An impeller is disposed within flexible bag and is coupled with the tubular connector. A steady support is mounted on the second end of the tubular connector and terminates at a distal nose, the distal nose being freely disposed within the retention cavity of the retainer so that the steady support can rotate within the retention cavity relative to the retainer.

In a stirred tank chemical reactor the mean age of the reactor contents affects a number of properties of the product, including for example the homogeneity of the product. The mean average age of the reactor contents can be determined by constructing a transparent model of the reactor and filling it with a fluid containing a fluorescent dye and having flow properties comparable to those of the reactor in use. A light is shone on the fluid as it is stirred under reaction conditions and a clear fluid flow into the model. Pictures are taken of the reactor contents and the mean fluid age of the contents of the model are determined relative to the exit age of the contents. This approach can be applied to determine for example which reactor ports to use, what agitator to use, what flow rates to use to improve reactor function.

A vapor hood for a proppant blending system, with a proppant entrance port to receive proppant, the proppant entrance port having a one way valve to allow the flow of proppant but prevent the backflow of vapor when the proppant is not entering the vapor hood.

Provided are systems, methods, and apparatuses directed to a container for storing a liquid, the container including a textured surface configured to increase the liquid's dissolved oxygen content, the textured surface having fluid-obstructions configured to disrupt a flow of the liquid in at least one direction, said disruptions being effective to decrease a surface tension associated with the liquid and increasing a surface area associated with the liquid.

A volumetric instrument serving as a universal mixture maker. The instrument comprises fixed-shape solute cups that can be submerged in and fastened to solvent containers. The design allows a human operator to run an iterative method which finds a solution to a set of multivariate equations that would otherwise require situation-specific analytical calculations and the use of weighing scales. The iterative method can solve for one or more variables including solute volume, solvent volume, final mixture volume, and final solute concentration level. Cups and containers act as a mechanical calculator with a single parameter for the operator to manually adjust: how much of a solute cup to submerge in a solvent container. The mechanical calculator reduces mixture equations down to two markings for the operator to visually align: an output mixture marking on a cup, and a volumetric marking on a container.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment; a retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag; and an elongated member having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within the retention cavity of the retainer so that the second end of the elongated member can rotate within the retention cavity relative to the retainer.
