A syringe assembly for a hydraulic fracturing system includes a syringe having a material chamber, a base fluid chamber, and a piston. The material chamber is configured to be fluidly connected to a fluid conduit. The piston retracts to draw material into the material chamber. The piston extends to push the material into the fluid conduit. The syringe assembly includes a diverter fluidly connected to the base fluid chamber and moveable between first and second positions. The first position of the diverter fluidly connects the base fluid chamber to a base fluid reservoir of the hydraulic fracturing system and fluidly disconnects the base fluid chamber from an outlet of a frac pump of the hydraulic fracturing system. The second position of the diverter fluidly connects the base fluid chamber to the outlet of the frac pump and fluidly disconnects the base fluid chamber from the base fluid reservoir.

Disclosed herein are a method for producing a miniaturized liposome on a large production scale, and an apparatus for producing a liposome which is to be used in the above-mentioned method. Provided is a method for producing a liposome, including a step of stirring a mixture containing an oil phase in which at least one lipid is dissolved in an organic solvent and a water phase in a first tank of an apparatus having the first tank and a circulation path, in which the ratio of the capacity of the circulation path to the total capacity of the tank and the circulation path is 0.4 or less and/or the time required for the mixture to return to the first tank after being discharged therefrom is within 2.0 minutes.

Dilute chemical solution production device has a plunger pump and a chemical solution supply pipe that supply a chemical solution from a chemical solution reservoir. The end of the chemical solution supply pipe serves as an injection point for the chemical solution. The chemical solution supply pipe is inserted to an approximately central position in the radial direction of an ultrapure water passage, which is a first pipe, via a bore-through joint. Conductivity meter as a conductivity measuring means is provided on the downstream side of the bore-through joint, which serves as the injection point, and is connected to the previously described control means so that the plunger pump can be controlled in accordance with the measured value of the conductivity meter. The dilute chemical solution production device is capable of producing, with a simple structure, a dilute chemical solution having an extremely low concentration of acid/alkali or the like.

A wipe dispenser for use in metering out consistent doses of a composition onto a disposable wipe includes a mixing and dispensing assembly. The assembly has a vessel holding a first liquid for the composition and a first pump to convey the first liquid. A bottle having a second pump to convey a second liquid of the composition is stored within the bottle. A funnel arrangement is in downstream communication with the first pump and second pump. The funnel arrangement includes a mixing chamber for mixing the first and second liquids and a dispensing funnel in communication with and downstream of the mixing chamber. A wipe can be pulled through the dispensing funnel and wetted with a mixture of the first liquid and second liquid from the mixing chamber. A push bar attached to the funnel arrangement can selectively apply the force to actuate the first pump and second pump.

A microsphere cavity that forms a whispering gallery mode is used. By vibrationally coupling a whispering gallery mode being one of kinds of an optical mode to a vibrational mode of water or a liquid other than water, ultra strong coupling water or a liquid in a vibrational coupling state is generated. A first example is to acquire aerosol in which water itself or a liquid itself other than water constitutes a micro-water sphere cavity or a micro-liquid sphere cavity (50) and is a dispersoid. A second example is to acquire colloid or emulsion in which a micro-dielectric sphere cavity (53) is a dispersoid and water or a liquid other than water is a dispersion medium.

A device (1) for producing a solution of at least one liquid first medium and at least one second medium has a first container (2) for the first medium and a second container (3) for the second medium. Each container (2, 3) is connected to a supply line of a static mixer (9) via a pump (4, 5) that can be regulated by a controller (6). A sensor (10) is connected to the controller (6) downstream of the static mixer (9) in the flow direction. A branching valve (17) is downstream of the static mixer (9) in the flow direction and is controlled by the controller (6). A sterile filter (11) is downstream of the static mixer (9) and has an RFID tag (15) that stores process-relevant data to at least be read by the controller (6). A method also is provided for producing a solution using the device.

The technology of the present application provides a flex or flexible tint system for stains. In certain aspects, the system comprises a known volume of an unpigmented stain and a colorant cartridge of containing a known volume of colorant. The colorant cartridge has a movable bottom and a discharge nozzle at the top. The movable bottom is movable along the colorant cartridge to consistently deliver a known discharge volume of colorant to the known volume of unpigmented stain. The colorant and unpigmented stain are mixed to achieve a stain of the desired color consistently.
