An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure fluid stream and passes the fluid through an electrode of a nozzle assembly to charge droplets of the atomized fluid.

A nucleation nozzle for forming freezing nuclei for devices for making artificial snow, starting from a jet of pressurised liquid, comprising a compressed air duct having an inlet opening and an outlet opening. A first stretch of the compressed air duct has a cross section which decreases in the flow direction of the compressed air, from the inlet opening to the outlet opening. The first stretch is followed by a second stretch having a cross section which increases in the flow direction of the compressed air from the inlet opening to the outlet opening. There is provided at least one water duct having an inlet opening and an outlet opening. The water duct is separate from the compressed air duct. The outlet opening of the water duct is positioned close to the outlet opening of the compressed air duct.

A spray head for directing water into a spray pattern that includes a casing configured to receive a supply of water and a plurality of nozzles disposed on the casing with each nozzle being configured to emit water in a stream away from the casing. The plurality of streams of water from the plurality of nozzles are configured to form a hyperboloidal shaped spray pattern.

An atomizing spray device includes a housing having inlets that receive a first fluid and a slurry of ceramic particles and a second fluid. The inlets are fluidly coupled with outlets by an interior chamber that mixes the first fluid with the slurry to form a primary mixture of the first fluid and first atomized droplets of the slurry. A first outlet on a first side of the housing and a second outlet on the first side of the housing are shaped to change the primary mixture to form a secondary mixture of the first fluid and second atomized droplets of the slurry. The first outlet sprays the secondary mixture onto a first surface as a first layer of coating and the second outlet sprays the secondary mixture onto the first surface as a second layer of coating while the housing moves in a direction along the first surface.

A discrete dispensed product comprising a first portion; and a second portion at least partially surrounding the first portion provides a premium and distinct appearance to consumers.

Apparatus, systems, and methods for identifying and quantifying chemical components in a high-melting-point liquid. One such method includes: receiving, into a nebulizer assembly, a high-melting-point liquid from a molten liquid conduit; aerosolizing, using the nebulizer assembly, at least a portion of the received high-melting-point liquid; delivering, into one or more instruments, the aerosolized high-melting-point liquid from the nebulizer; and chemically analyzing, using the one or more instruments, the aerosolized high-melting-point liquid.

There is described a fire-fighting apparatus comprising a housing comprising an upstream air inlet and a downstream fire-extinguishing stream outlet and a hollow body therebetween, wherein the housing houses an air stream traveling at high velocity; and a spray assembly concentrically mounted to the housing. The spray assembly comprises a fluid inlet connected to a source of fluid outside the housing; and a plurality of injecting assemblies fluidly connected to the fluid inlet and designed for breaking down an inflow of the fluid into droplets and projecting the droplets of the fluid within the air stream in a multiphase fire-extinguishing stream. The injecting assemblies each comprises a fluid outlet; a base plate through which extends the fluid outlet; a holding structure mounted to the base plate and extending downstream therefrom, and a unibody jet-fragmenting device mounted to the holding structure facing the stream of fluid exiting the fluid outlet.

A thermal fogger includes an air-supply system and a chemical injector. The air-supply system includes an air chamber, a pre-heater configured to heat air in the air chamber, and a blower in fluid communication with the air chamber and configured to blow a flow of heated air through an outlet of the air chamber. The chemical injector is coupled to the outlet of the air chamber and is configured to inject a liquid chemical into the flow of heated air to produce an air-chemical mixture.
