A fine water particle release device includes: a case formed in a cylindrical shape having both ends opened; a fine water particle generating element accommodated in the case and generating uncharged fine water particles; an air blowing member operating to allow air to flow into the case from one end and allow the air flowing into the case to be released from the other end; a discharge element including first and second electrodes separated from each other, the discharge element causing discharge in a discharge space between the first and second electrodes by applying a voltage between the first and second electrodes, and being disposed such that the fine water particles pass through the discharge space together with the air; and a control device controlling the discharge and a generated moisture amount generated in the fine water particle generating element.

The invention includes an air mover device used for fire mitigation and protection. The core component is an air mover unit whose discharge airstream can be positioned using air rudders to provide air flows in optimum directions and capacity to counter unwanted fire progression or to promote fires in cases of back-burns. Additional support components include a power supply, its fuel source, a speed control mechanism for the air mover, an air mover inlet protective screen, a sparger unit to impart suppressant or retardant into the airstream, and instrumentation and controls to ensure function and safety of equipment and personnel. This device can be on a static or mobile platform, towed or self-propelled and can be locally or remotely controlled.

A device and to a process which can be carried out using the device, for the production of fine particles from a liquid which solidifies upon cooling, in particular from liquid fat. The process has the advantage of producing fine particles of very small size, preferably with narrow size distribution. The device has the advantage that a solidifying liquid can be supplied at a temperature above its solidification temperature, without cooling gas leading to solidification of the liquid in the supply line, which cooling gas is used in the production of the particles.

A vehicular cleaning system performs cleaning to remove foreign matter attached to a cleaning target in a vehicle. The vehicular cleaning system includes: an air pump driven to generate an air spray; a washer pump driven to supply a washing solution; a spray nozzle which blows an air-liquid mixed fluid, obtained by mixing the air spray and the washing solution, onto the cleaning target; a washing solution storage unit configured to store the washing solution supplied from the washer pump, and to be capable of discharging the stored washing solution when the washing solution is to be mixed with the air spray; and a mixing and outputting unit configured to blow the air-liquid mixed fluid, obtained by mixing the air spray and the washing solution introduced from the washing solution storage unit, from the spray nozzle toward the cleaning target.

The application provides a disinfecting device. The device comprises an aircraft trolley-sized body comprising two side surfaces. The body is adapted to move along a longitudinal axis of an aisle of an aircraft such that the side surfaces face two opposing sides of the aisle. The device includes a powering unit, at least one air compressor for providing compressed air, a disinfectant bottle for storing liquid disinfectants, and at least two nozzle assemblies. Each nozzle assembly includes an electrically actuated valve, a connector, and at least three nozzles. The compressed air flows from the compressor to the valve, to the connector, and to the nozzles to form droplets of disinfectants. The nozzles are provided on upper surfaces of the body such that the nozzles point away from the respective side surfaces for spraying the disinfectants onto objects located on the two opposing sides of the aisle.

A device for atomization of water and essential oil includes a water atomization assembly, an essential oil atomization assembly, and a vacuum pump. The water atomization assembly includes a first housing, a water container disposed in the first housing, an ultrasonic atomization module disposed in the first housing to atomize water from the water container. The essential oil atomization assembly includes a second housing, an essential oil atomization module disposed in the second housing, and an essential oil container. The vacuum pump is fixedly disposed on a bottom end of the first housing. The essential oil atomization module is connected to and disposed above the essential oil container; the essential oil container is at least partially disposed in the second housing; the first housing includes an outer wall including a recess, and the second housing is fixedly embedded in an upper part of the recess.

In some examples, a moveable member including multiple tools is moveable relative to a fixed member to position a selected tool for performing an operation. A first connector half may be included on the fixed member for connecting to one of a plurality of second connector halves included on the moveable member. Movement of the moveable member to position the selected tool for performing the operation moves a respective second connector half associated with the selected tool into connection with the first connector half. In addition, a respective nozzle assembly may be associated with each tool. The respective nozzle assembly may receive multiple fluids including at least one fluid received through the connection between the connector halves. The nozzle assembly includes an inner nozzle that outputs a gas and an annular outer nozzle that outputs a machining liquid to generate a mixture to direct toward a tool-workpiece interface.

Delivering a payload across a plasma membrane of a cell includes providing a population of cells and contacting the population of cells with a volume of an aqueous solution. The aqueous solution includes the payload and alcohol content greater than 5 percent concentration. The volume of the aqueous solution may be a function of exposed surface area of the population of cells, or may be a function of a number of cells in the population of cells. Related compositions, apparatus, systems, techniques, and articles are also described.

A twin-fluid atomized aerial spray system and method of aerial spraying includes flying an atomized spray delivery system with an unmanned aerial system. The atomized spray delivery system includes a first fluid delivery path, a second fluid delivery path and a spray nozzle. The first fluid delivery path has a liquid tank and the second fluid delivery path has a compressed gas tank, wherein the first and second fluid delivery paths deliver respective fluids to the spray nozzle. Liquid from the liquid tank is atomized with compressed gas from the compressed gas tank at the spray nozzle and delivers the atomized spray from the spray nozzle.
