A viscous liquid supply apparatus includes a storage tank (10) that stores viscous liquid, and a pump (14) that supplies the viscous liquid stored in the storage tank to a use point, wherein the viscous liquid supply apparatus is configured with a viscometer (20) that measures a viscosity of the viscous liquid stored in the storage tank, and a replenishment device (30) that supplies replenishment liquid to the storage tank based on the viscosity measured with the viscometer. The viscometer (20) is a rotary type viscometer that has a rotor (23) in a cylindrical shape wherein the rotor is immersed in the viscous liquid and rotates therein, and the rotor is configured with a stirring blade that agitates the viscous liquid inside the storage tank (10).

The present invention relates to a device and method for making sclerosing foam, which is useful in the treatment of varicose veins and other venous conditions. The device comprises a continuous pathway that is at least partly formed of flexible or compressible material and that comprises a foam generating structure within the continuous pathway; the foam generating structure being formed of two or more elements, wherein each element defines at least one passageway of cross sectional area 1 μm2 to 10 mm2 and said two or more elements being arranged in series; a port which allows introduction of material into or extraction of material out of the continuous pathway; and a liquid pathway that is at least partly formed of flexible or compressible material and is arranged to deliver liquid into the foam generating structure between a first and second element of the foam generating structure.

A mixing silo for bulk material comprises a silo container, a mixing installation mounted in the silo container for mixing the bulk material, at least one shut-off element for shutting off the mixing installation, wherein the mixing silo has a minimum extraction rate and the silo container, with the mixing installation shut off, has a residual cross-sectional area which ensures a mass flow of the bulk material that is greater than or equal to the minimum extraction rate of the mixing silo.

A device and method for in-line homogenizing a non-uniform feed stream is described herein, which includes a plug flow reactor (PFR), a bypass line, and a pump in a closed-circuit flow path that allows for rapid homogenization of the non-uniform feed stream.

A resistivity regulating apparatus includes: a gas dissolving device that causes a regulating gas to dissolve in a liquid targeted for resistivity regulation to generate a treated liquid in which the regulating gas is dissolved in the liquid, the regulating gas being used to regulate a resistivity of the liquid; and a buffer tank to which the treated liquid discharged from the gas dissolving device is fed.

A fine bubble generator may include an inlet, an outlet, a first fine bubble generation portion including a first flow path, and a second fine bubble generation portion including a second flow path. The first flow path may include a diameter-reducing flow path and a diameter-increasing flow path. The second flow path may include a guide flow path and a collision flow path disposed downstream of the guide flow path. A first bearing and a first impeller rotatably attached to the first bearing may be disposed on the collision flow path. The first impeller may include a disc disposed at a position at which the gas-dissolved water collides with the disc; a first rotation shaft disposed on a downstream surface of the disc and rotatably attached to the first bearing; and one or more first vanes disposed on an upstream surface of the disc.

A system and a method are provided for making hypochlorous acid using saltwater with sodium bicarbonate. The system includes an electrolytic cell, a quantity of saltwater solution, and a quantity of sodium bicarbonate. The quantity of saltwater solution is poured into the electrolytic cell and then undergoes an electrolytic process. As a result of the quantity of saltwater solution going through the electrolytic process, a hypochlorous acid solution is yielded. In order to ensure a pure hypochlorous acid solution is formed, the quantity of sodium bicarbonate can be added into the electrolytic cell along with the quantity of saltwater solution before the electrolytic process or the quantity of sodium bicarbonate can be added into the hypochlorous acid solution after the hypochlorous acid solution is yielded. This process adjusts the pH level of the hypochlorous acid solution, and thus, produces a purer hypochlorous acid solution.

A “FirePOD” provides a self-contained, portable, standalone fire protection system that enables property owners, firefighters or others to mix and apply fire-protective gel or foam to entities such as structures, vehicles, vegetation, etc., to protect those entities from wildfire events or other external fire incidents. In various implementations, the FirePOD includes a recirculation-based mixing system for combining a mixture comprising a powder, liquid, or gel-based Thermal Protective Substance (TPS) with a volume of water or other liquid to produce the fire-protective gel or foam. By applying reconfigurable valves, one or more pumps are applied to both recirculate the mixture and, when sufficiently mixed, apply the resulting fire-protective gel or foam via one or more hoses or other dispensing mechanisms. In various implementations, the FirePOD is movable, and is manually or automatically propelled to locations suitable for applying the fire-protective gel or foam.
