A system and method for forming a polyurethane foam includes supplying an isocyanate component from a source of isocyanate to a proportioner. A resin component from a source of resin is supplied to a metering unit and an additive having an unstable state from a source of additive is supplied to the metering unit. The resin component and the additive form a reactive mixture when combined. The system and method includes delivering the reactive mixture by the metering unit to an accumulator and storing the reactive mixture in the accumulator. The system and method further includes demanding a supply of the reactive mixture with the proportioner and supplying the reactive mixture by the accumulator to the proportioner and mixing the reactive mixture with the isocyanate component by the proportioner to form the polyurethane foam.

A method for effective and efficient water or wastewater aerosolization and industry specific and regulatory agency approved ADC, soil stabilization or penetrating solution dissemination over identified and specific areas that are to be addressed. The water or wastewater and industry or regulatory body specifically approved ADC, soil stabilization or penetrating reagent solution(s) is directed to an Integrated Mobile Aerosolization System (IMAS) or other system having a turbine and being integrated and mobile. The turbine is driven so as to generate a system of air. Integrated pumps are utilized to move the water or wastewater and industry or regulatory body specific and ADC, soil stabilization or penetrating reagent solution(s) to a series of nozzles that aerosolizes the water or wastewater and ADC, soil stabilization or penetrating reagent solution into the path of the system of air. The water or wastewater and ADC, soil stabilization or penetrating reagent solution form a mixture that is entrained in the system of air. The mixture of water or wastewater and ADC, soil stabilizing or penetrating reagent solution is directed over a specific area that is to be covered with an approved material. The water or wastewater and ADC, soil stabilization or penetrating reagent solution form that industry specific and regulatory body approved covering material that is applied to the specific area.

A robotic orchard spraying system having autonomous delivery vehicles (ADV), each autonomously delivering an amount of a premixed solution over a non-overlapping path verified by a forward-looking sensor, video, or both. Also, a mobile control center, configured to wirelessly inform the autonomous delivery vehicle of the path within the areas and to confirm that the autonomous delivery vehicle is following the path within the area. Additionally, a mapper vehicle generates the path within the area, the mapper vehicle being configured to communicate information about the path and the area to the command center. The mapper vehicle senses the path with a forward-looking LiDAR sensor, and senses the area with a GPS sensor. Moreover, a nurse truck has a reservoir of premixed solution for replenishing a tank of the ADV. ADVs and the control center communicate over a radio network, which may be a mesh network, a cellular network, or both.

The present invention relates to a spraying assembly comprising an injection device, a first hydraulic circuit for conveying carrier liquid to a spray nozzle, the first hydraulic circuit comprising, upstream of the spray nozzle, an injection section, a second hydraulic circuit for conveying the active substance to the injection device, under an injection pressure greater than the carrier liquid circulation pressure, the injection device comprising a direct dosing interface comprising a plurality of through-holes in the injection section of the first hydraulic circuit, and the injection device further comprising at least one corresponding actuator configured to open or close each through-hole so as to allow a determined dosing of active substance to pass through at least one open hole to be injected into the carrier liquid stream.

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.

The present invention addresses the problem of providing an atomizer that is easy to handle and that is particularly suitable for atomizing a cosmetic material. The present invention comprises: an atomizer body 2 that has a coating composition atomizing head 2a at a leading end thereof; a pressure tank 3 that is filled with a compressed gas; and a gas supply pipe 4 that supplies the pressurized gas to the atomizing body from the pressure tank. A composition supply tank 5 that supplies the coating composition and an operation part C that causes the coating composition to be sprayed from the atomizing head are provided between the leading end and a trailing end of the atomizer body. A substantially ovoid-shaped gripping part G that is gripped by the palm of a hand of a user is formed at the trailing end of the atomizer body.

A system for metering liquids at very low flows for use with agricultural sprayers is provided. The system may utilize two electronically controlled solenoid valves in series with a storage chamber in between. The flow may be a function of the PWM control of each of the valves, the phase relationship between the control signals, the storage chamber in between, the pressure difference across the metering device, and the fluid being metered.
