A system for movement of fluid in a tank comprises: a tank; at least two pumping sets, each pumping set comprising: a pumping line external to the tank and in fluidic communication with the interior of the tank at two separate points of the tank via the two ends of said pumping line, and a pump configured to circulate fluid through the pumping line, wherein each pumping set is configured to collect fluid from the tank at one end of its respective pumping line, circulate the fluid through its respective pumping line and discharge the fluid into said tank through the other end of its respective pumping line, and wherein each pumping set is configured such that the flow of fluid in its respective pumping line is reversible.

A microreactor system that can mix fluids at precise timing has two inlets into which fluids are introduced and merges, in a channel, a first fluid introduced from a first inlet and a second fluid introduced from a second inlet, a first pump that sends the first fluid toward the inlets, and a second pump that sends the second fluid toward the inlets, a first fluid detector that detects an arrival of the first fluid at the first inlet, and a second fluid detector that detects an arrival of the second fluid at the second inlet.

An ozone water treatment system using low energy. The present invention includes: a water pipe through which raw water, to be treated, is transferred and supplied while having energy; a gas injector for dispersing and injecting, in a micro bubble form, ozone gas to the raw water supplied and transferred from the water pipe; a low-energy using-type gas-liquid contact reactor for promoting a contact reaction between the ozone gas and the raw water within ozone mixed water supplied and transferred from the gas injector; and a discharge pipe for continuously transferring and discharging treated water having been reaction-treated. Therefore, since energy use during the ozone gas injection and the contact reaction can be remarkably reduced, processing costs can be reduced.

The invention relates to a plastic mesh having a plurality of chains extending parallel to one another in a longitudinal direction, which plastic mesh has a plurality of groups of chains (2) adjacent to one another, which are in each case formed of at least two chains (2a, 2b). The groups of chains (2) have a greater spacing relative to one another or also relative to a further individual chain (1) than the chains (2a, 2b) within a group of chains (2). A thread (3) runs in a zigzag between two adjacent groups of chains (2) or also between one group of chains (2) and an individual chain (1) and connects the chains (1) or groups of chains (2).

A humidifying apparatus includes a nozzle and a base on which the nozzle is mounted. The nozzle has respective first and second air inlets, air outlets and interior passages for conveying air therefrom and thereto. The nozzle defines a bore through which air outside the humidifying apparatus is drawn by air emitted from the air outlets. The base generates first and second air flows through the respective first and second interior passages, and a water reservoir. First and second air passageways convey the first and second air flows to the respective first and second air inlets. As the second air passageway conveys the second air flow over the water in the reservoir, water stored in the reservoir is agitated. An ultraviolet radiation generator irradiates the agitated water for a period of time before water stored in the reservoir is atomized to increase the humidity of the second air flow.

A locking member that locks a mixing nozzle to a cartridge that includes two syringes, the mixing nozzle being configured to mix the materials from the two syringes within the nozzle as the materials are discharged. The locking member includes a support rod supported on the mixing nozzle that is displaceable in a direction orthogonal to the direction in which the nozzle extends, and first and second engaging parts that engage with horizontal parts provided on the cartridge. The locking member further includes an inclined part that is inclined toward the opposite side to the nozzle, and that is provided between at least one of the first engaging part and the second engaging part, or between the second engaging part and the other end of the support rod.

A mixing device includes a conveying part, a discharging pipe and a detecting part. The conveying part is internally provided with a plurality of conveying channels, and the plurality of conveying channels are used for correspondingly conveying various materials. The discharging pipe is internally provided with a mixing channel and connected to the conveying part, and each of the conveying channels communicates with the mixing channel. The detecting part is used for detecting a color of the mixed material obtained after the various materials are mixed in the mixing channel.

A mixing system for a power washer includes an electrically actuated valve communicated with a supply of a working fluid, and having a valve head that is movable between open and closed positions to control the flow rate of the working fluid through an outlet of the valve. The outlet of the valve is communicated with a fluid passage of the power washer to enable flow of the working fluid into a primary fluid and discharge of a mixture of the primary fluid and working fluid from the power washer when the valve is open, and to provide a flow of primary fluid from the power washer when the valve is closed.

Processes for processing bio-sourced oil to produce bio-sourced oil dielectric fluids can be carried out using an apparatus mounted on a mobile transport platform system having a total footprint of no more than about 30 m.sup.2. The processes use a described array of pumps, heaters, filters, a degasser and vacuum system, and an additive metering/mixing valve system to achieve production under low energy and pressure conditions.

An exemplary compounding method of controlling a compounding device to prepare an admixture of at least two distinct material sources can include examining material source solutions for incompatibility of the ingredients and operating a first and a second pump to prevent one of the incompatible source solutions from entering a common flow path. The processing method can detect degradation of a fluid line by evaluating one or more of calibration error rate data, cumulative volumetric flow data, or cumulative pump operation data. The processing method can also selectively transfer a first group of source solutions using the first pump, receiving pump data from one or more sensors that sense actions of the pumps, applying fluid correction factors and calculating discrete pump movements, the pump movements being indicative of an amount of source solution displacement by a pump, and operating the pumps to selectively dispense the source solution amounts according to a preparation order.
