A jet injection device that incorporates nanobubbles (ultrafine bubbles) in a mist includes: a two-fluid nozzle configured from a circular nozzle outer cylinder and an air connection tube integrally and perpendicularly connected to the nozzle outer cylinder; a nanobubble generation device that supplies the nozzle outer cylinder of the two-fluid nozzle with high-pressure nanobubble water; and a compressor that supplies the air connection tube of the two-fluid nozzle with high-pressure air. The gas-injected bubble water generated from the nanobubble generation device is pressure-fed to the nozzle outer cylinder of the two-fluid nozzle, and compressed air from the compressor is pressure-fed to the air connection tube of the two-fluid nozzle. In the two-fluid nozzle, the high-pressure gas-injected bubble water and the compressed air serve as a gas-liquid fluid mixture, and are injected at a high speed in mist form from a nozzle cylinder of the two-fluid nozzle.

Provided are a cleaning method and cleaning device for cleaning with micro/nano-bubbles, with which a simple method of spraying a treatment solution containing micro/nano-bubbles onto a substrate to be processed makes it possible to efficiently and reliably peel off residual resist or remove contaminants from the substrate, while reducing an environmental load. This cleaning method is characterized in that, with respect to a substrate to be treated to which a resist film has adhered onto the substrate or a substrate to be treated to which the surface thereof has been contaminated with a metal or metal compounds, the resist film is peeled off or the metals or metal compounds are removed by spraying onto the substrate to be treated a treatment solution containing gaseous micro/nano-bubbles and having a temperature maintained at 30 C. to 90 C., the mean particle size of the micro/nano-bubbles when measured by an ice embedding method using a cryo-transmission electron microscope being 100 nm or smaller, preferably 30 nm or smaller, and also preferably the density of such bubbles being 10.sup.8 or more bubbles per 1 mL.

A method, apparatus, and system for obtaining a solution from a solid product are disclosed. A solid product is housed in a dispenser. A liquid is introduced into the housing of the dispenser to interact with the solid product to form a solution. To control the concentration of the formed solution, the turbulence of the liquid introduced to the dispenser is controlled and adjusted either manually or on a real time basis to account for varying characteristics of either or both of the solid product and the liquid. The dispenser will adjust the turbulence based on the characteristics to maintain a formed solution within an acceptable range of concentration. The concentrated solution can then be discharged from the dispenser to an end use application.

Providing electric power distribution for fracturing operations comprising receiving, at a transport, electric power from a mobile source of electricity at a first voltage level and supplying, from the transport, the electric power to a fracturing pump transport at the first voltage level using only a first, single cable connection. The first voltage level falls within a range of 1,000 V to 35 kilovolts. The transport also supplies electric power to a second transport at the first voltage level using only a second, single cable connection.

A mixer assembly for mixing two air streams in a ventilation system. The mixer assembly comprises a mixing chamber, which comprises an inlet and an outlet and a mixing chamber wall delimiting the mixing chamber, and also a shroud, which surrounds the mixing chamber wall, at least in certain portions. The shroud forms and delimits an intermediate space between the mixing chamber wall and the shroud. The mixer assembly also comprises a filter element, which fluidically connects the intermediate space to a surrounding area of the mixer assembly, the intermediate space being fluidically connected to the mixing chamber. Fluid can thus flow through the filter element into the intermediate space and further into the mixing chamber. A stowage space with a mixer assembly, an aircraft with such a stowage space and a method for producing a mixer assembly in an aircraft are also described.

A tank system includes a primary arm and a secondary arm mounted on a trolley. Each arm is configured to independently rotate 340 to 360 degrees in horizontal planes. The primary arm includes a pivot frame for adjusting the vertical position of the secondary arm by pivoting the primary arm in a vertical plane. At least one nozzle and a submersible pump are mounted to the secondary arm. The tank system is mounted within a tank or other enclosure by securing the trolley to a track system within the tank or other enclosure. The trolley is configured to move along the track system within the tank or other enclosure. The tank system may pump a fluid from the tank in a pumping configuration, mix the fluid within the tank in a mixing configuration, and/or clean the tank in a cleaning configuration.

The invention relates to methods for the chemical application of coatings by the decay of gaseous compounds, in particular to methods for injecting gases into a reaction chamber. The invention also relates to means for feeding gases into a reaction chamber, said means providing for the regulation of streams of reactive gases, and ensures the possibility of obtaining multi-layer epitaxial structures having set parameters and based on nitrides of group III metals while simultaneously increasing the productivity and cost-effectiveness of the process of the epitaxial growth thereof. Before being fed into a reactor, all of the gas streams are sent to a mixing chamber connected to the reactor, and are then fed into the reactor via a flux former under laminar flow conditions. The mixing chamber and the flux former are equipped with means for maintaining a set temperature. As a result of these solutions, a gaseous mixture with set parameters is fed into the reactor, and the formation of vortices is simultaneously prevented. The maximum allowable volume of the mixing chamber is chosen to take into account the process parameters and the required rarity of heterojunctions.

A liquid filling system is provided that contains a container and a nozzle, while such nozzle contains liquid flow passages that are configured to generate different liquid influxes that are directed differentially toward the bottom and the sidewall(s) of such containers.

An immiscible droplet generation system may include a chip, a microfluidic channel integrated into the chip, an input to the microfluidic channel through which the microfluidic channel is to be filled with a first fluid that is to be moved through the microfluidic channel and a droplet generator. The droplet generator is integrated into the chip to generate a droplet of a second fluid, immiscible within the first fluid, and to inject the droplet into the first fluid in the microfluidic channel.
