Systems and methods are disclosed that include a spraying apparatus having a hand held spraying device, a flexible reservoir connected in fluid communication with the hand held spraying device and worn on the body of a user of the spraying apparatus, and a pressure device that provides pressure to the flexible reservoir to move fluid from the flexible reservoir to the hand held spraying device.

A system and method for dermal spraying includes a portable, hand-held dermal application device with one or more disposable cartridges that spray a dermal formulation onto the skin, the disposable cartridge having a nozzle that can be activated by placing the cartridge into the spray device.

Ampoules for a semiconductor manufacturing precursors and methods of use are described. The ampoules include a container with an inlet port and an outlet port. The inlet port has a showerhead that the end within the container. The showerhead has at least two angled nozzles to direct the flow of gas within the cavity so that the gas flow is not perpendicular to the surface of a liquid within the ampoule.

A chemical agent-spraying device is provided with a chemical agent tank and chemical agent-jetting parts that jet out a chemical agent supplied from the chemical agent tank. The chemical agent-jetting parts include a first chemical agent-jetting part that jets out the chemical agent onto the reverse surfaces of crop leaves as an area to which the chemical agent is to be jetted, and a second chemical agent-jetting part that jets out the chemical agent onto the obverse surfaces of crop leaves as an area to which the chemical agent is to be jetted.

A mist blower in one aspect of the present disclosure includes an air blower, an air feed pipe, a tank, a liquid feed pipe, a nozzle, a first electromagnetic valve, a controller, and a first manual switch. The first electromagnetic valve (i) opens the liquid feed pipe in response to the first electromagnetic valve being activated and (ii) closes the liquid feed pipe in response to the first electromagnetic valve being deactivated. The controller activates or deactivates the air blower and the first electromagnetic valve. The first manual switch (i) is manually moved by a user of the mist blower and (ii) commands the controller to activate or deactivate the air blower based on a movement of the first manual switch.

A device may receive data from a portable applicator as the applicator moves from a first position from a user to at least a second position from the user. The device may process the data to create a map of the user and transmit the map to a display on a remote computing device, wherein the user is permitted to select one or more target profiles to be applied to the user via the portable applicator. The device may transmit a signal to the portable applicator when the user makes a selection and commence dispensing of the selected target profile in an atomized mist on the user.

A mix on exit sprayer having a water tank and a body the includes a chemical cartridge receiving cavity. A pump move water from the tank to a mixing chamber and a piston drives chemical concentrate from the cartridge into the mixing chamber. A venturi style mixing element mixes the water and concentrate and the pump moves the mixed fluid from the mixing chamber to a spray wand from which it can be expelled.

Proposed are a chemical liquid supply unit, a substrate processing apparatus having the same, and a chemical liquid supply method. More particularly, proposed is a technique for supplying chemical liquids of different flow rates, in which a chemical liquid is supplied at the same flow rate to each of a plurality of chemical liquid lines and the flow rate of the chemical liquid is adjusted through a flow control valve disposed on at least one chemical liquid line selected among the plurality of chemical liquid lines, so that the plurality of chemical liquid lines can supply chemical liquids at different flow rates.

A valve including a feed mechanism, a mixing element operably connected to the feed mechanism, wherein the feed mechanism delivers at least two fluids to the mixing element, the at least two fluids being mixed in the mixing element, and an air cap disposed proximate an outlet of the mixing element to atomize the mixed fluids exiting the outlet of the mixing element, is provided. Furthermore, an associated method is also provided.

A system for affecting motion of an amusement ride vehicle is disclosed. The system includes a channel and a plurality of fluid spray sources positioned to spray at least a primary fluid over the channel. For at least one of the fluid spray sources, the system is adapted to inject a secondary fluid into the primary fluid to modify at least one of a pressure and a velocity of the primary fluid. A corresponding method is also disclosed.
