A method of atomizing a liquid comprising providing the liquid to a liquid duct in a dispensing body, providing a gas to a gas duct in the dispensing body, and introducing the liquid into a head via a plurality of liquid duct channels. The method further includes introducing the gas into a pressure chamber of a pressure cap, the pressure cap positioned proximate the dispensing body such that the head is positioned between the pressure cap and the dispensing body. The gas is expelled through a plurality of pressure chamber exit orifices, the pressure chamber exit orifices positioned proximate a plurality of liquid supply channel exit openings via an alignment spacer defined on the head. The method includes expelling the liquid from the liquid supply channel exit openings and through the pressure chamber exit orifices, such that the liquid and the gas interact and form atomized droplets of the liquid.

A spray ionization device is provided with: a first tube body having a first flow channel through which a first fluid can flow, and having, at one end thereof, a first outlet for spraying the first liquid; a second tube body having a second flow channel through which a second fluid can flow, and having, at one end thereof, a second outlet for spraying the second liquid; an outer tube that has a gas flow channel through which a gas can flow, the outer tube having, at one end thereof, a spray port that is covered with a porous member; and an electrode that is provided between the first flow channel, the second channel, and the first outlet or the second outlet and the porous member, the electrode allowing for a voltage to be applied to the first liquid and/or the second liquid by a power source.

An atomization powder making device suitable for atomizing molten metal to produce powder includes a housing defining an atomizing chamber, a vessel mounted inside the housing and defining a receiving space for receiving the molten metal, and a flow guide unit extending from the bottom of the vessel and having at least one liquid flow channel for conveying the molten metal from the receiving space to the atomizing chamber. A push unit is disposed in the receiving space for pushing the molten metal to flow through the at least one liquid flow channel. A gas supply unit is configured to supply an atomizing gas for atomizing the molten metal flowing out of the liquid flow channel.

Applicant discloses a novel method of spray applying multiple courses of a rapid cure, two part polymer sealant to an aircraft surface. The method sometimes uses a two part polymer mix for use in the aircraft industry that is applied with pneumatic mix and spray gun. The two part cartridge is used in the mix and spray gun so the mix is applied immediately upon mixing, but the two components are kept separated unless the gun is applying the mix. The multiple courses cure to form a clear sealant that allows for inspection of cracks and corrosion beneath the sealant. It cures quickly so that the coated part may be further processed, for example in the assembly line during aircraft build. Applicant further discloses multiple spray gun systems for applying such a two-part polymer mix to aircraft parts.

A battery module according to an embodiment of the present disclosure includes a battery cell stack containing a plurality of battery cells stacked along one direction, and a module frame for housing the battery cell stack. The battery cells adjacent to each other in the battery cell stack are coupled together by a first adhesive member including a cured spray-type adhesive is cured. The first adhesive member follows at least one fluctuating pattern that extends along a direction different from the direction along which the plurality of battery cells are stacked.

A spray gun includes a first shell, a fan module, a sleeve, a nozzle assembly and a spray bar assembly. The fan module includes a brushless motor. The sleeve is formed or mounted on the first shell. The nozzle assembly is disposed at an end of the sleeve. The spray bar assembly is received in the sleeve and configured to move along a longitudinal axis of the spray bar assembly to open or close the liquid outlet. The fan module has a maximum outer diameter D1 between 30 mm and 80 mm, and a rotation axis of the brushless motor is parallel to or coincident with the longitudinal axis of the spray bar assembly. In this way, the spray gun is more compact and consistent with ergonomics.

A spray head for atomising fluid ejected from a fluid conduit, the spray head comprising: a body having a longitudinal bore for receiving the fluid conduit such that a distal tip of the fluid conduit extends to a distal end of the longitudinal bore, the body being configured to direct a balanced flow of gaseous medium over the distal tip of the fluid conduit, when received within the longitudinal bore, so as to promote atomisation of the fluid as it is ejected from the distal tip of the fluid conduit, wherein the body comprises at least two radially separable segments, each of which defines part of the longitudinal bore, said at least two segments when combined forming said body having a longitudinal bore, whereby the fluid conduit is received within the longitudinal bore by locating said at least two segments around the fluid conduit.

An inductive electrostatic atomization nozzle includes a nozzle body. The nozzle body has an internal gas flow channel and a liquid flow channel surrounding the internal gas flow channel. An electrode ring is arranged around the liquid flow channel at an inlet of the liquid flow channel. In the inductive electrostatic atomization nozzle, the electrode ring is arranged at the inlet of the liquid flow channel, which ensures that the electrode ring is located far away from the outlet of the inductive electrostatic atomization nozzle.
