A spray ionization device comprising: a first pipe body that has a first flow path which allows a liquid to flow therethrough, and has, at one end thereof, a first outlet through which the liquid is sprayed out; a second pipe body that surrounds the first pipe body; and a third pipe body that surrounds the second pipe body with a space interposed therebetween, that has a second flow path allowing a gas to flow therethrough, and that has a second outlet at the one end. At least the leading end part of the third pipe body including the second outlet is made of an electrically conductive material so as to serve as an electrode. Charged droplets can be sprayed from the second outlet by applying an electric field to droplets sprayed from the first outlet using a power supply connected to the electrode.

Provided are nozzle assemblies for a spraying apparatus having an outer wall (146) having opposed inner and outer surfaces, a central aperture (136) extending through the outer wall, and a pair of auxiliary apertures (158) disposed on the outer wall (146). Each auxiliary aperture is aligned along a respective auxiliary axis (162) and areas of the inner surface (164) of the outer wall (146) adjacent to the auxiliary apertures (158) are countersunk to define ledges (166) that are axially symmetric about the auxiliary axes (162). These assemblies obviate problems associated with rotatable molding pins and also provide the unexpected advantage of providing axial alignment of the air flow profile as air is emitted from the auxiliary apertures.

The distal end being longitudinally displaced from the proximal end of the device. The device comprises a base at the proximal end for releasable connection to a magnetic sample holder of a liquid sample analysis device. The device further comprises a longitudinally extending projection having a radial inner portion, the projection extending from the base towards the distal end, the projection being arranged for receiving and holding a sheath. The device comprises at least one fluidic conduit, the fluidic conduit extending at least partially longitudinally within the radial inner portion, the fluidic conduit for the delivery of a liquid sample for analysis.

A paint spraying unit for generating a shaped paint jet, including a paint nozzle positioned in a gap, wherein the paint nozzle includes a needle with a needle head that deviates from a rotationally symmetrical cross sectional design and a paint outlet opening that deviates from a rotationally symmetrical cross sectional design. The needle head is displaceable in relation to the paint outlet opening along a longitudinal axis of the needle for controlling a needle valve formed by the paint outlet opening and the needle head. The needle head, with the paint nozzle in a closed position with reference to the longitudinal axis, closes the paint outlet opening in a positive locking manner. In this connection, the needle head and/or the paint outlet opening is/are formed by a material with elastic properties at least in a surface region with which the two components come in contact.

The present disclosure relates to a nozzle block applied to an electrospinning device, which includes a radiation nozzle having a hollow radiation needle for discharging a spinning solution to the outside; a means of piercing having a diameter smaller than that of the radiation needle, at least one of which is coaxially disposed inside the radiation needle; and a reciprocating mechanism for reciprocating the means of piercing and the radiation needle relative to each other, thereby preventing the solution from being solidified at the tip of the radiation nozzle or the radiation nozzle from being blocked by external contaminants even if the electrospinning process is temporarily interrupted in the middle.

The invention provides a method of packaging a sterilized product. The method includes the steps of providing a product and sterilizing the product. The sterilized product is enclosed in a first layer, which is substantially hermetically sealed to form a first sealed enclosure. The first sealed enclosure is enclosed in a second layer, which is substantially hermetically sealed to form a second sealed enclosure. The second sealed enclosure is enclosed in a third layer, which is substantially hermetically sealed to form a third sealed enclosure. The third sealed enclosure is enclosed in a fourth layer, which is substantially hermetically sealed to form a packaged product.

A printer is configured to provide a jet of extraction gas that extracts a printing fluid from a printing nozzle in the presence of an electric field that accelerates the extracted printing fluid toward a printing substrate. The printer is also configured to selectively turn the electric field and the jet of extraction gas off and on to enable printing in gas-extraction mode, an e-assisted gas-extraction mode, or an e-jet mode. The jet of gas can be provided by a second nozzle concentric with the printing nozzle. A third nozzle can discharge a focusing gas around the extracted printing fluid.

A swirler-ferrule assembly includes a radial swirler, a ferrule, a fuel nozzle, and a surface feature. The radial swirler includes a primary swirler vane having a primary air passage and a secondary swirler vane having a secondary air passage. The ferrule may be connected to the radial swirler. The surface feature may be located on the primary swirler vane and/or the ferrule. The surface feature may be configured to direct an air flow through the primary air passage away from a recirculation zone located upstream of the primary swirler vane. The surface feature has a trailing end and a distal end, and the fuel nozzle is axially aligned with the trailing end of the surface feature or is located axially downstream of the trailing end of the surface feature. The surface feature may have a plurality of grooves.

There is provided a spray gun configured to atomize a liquid by using a compressed gas. The spray gun comprises: a gas cap configured to inject the compressed gas; and a liquid nozzle configured to inject the liquid, wherein the gas cap comprises a center gas flow path that has an opening provided in a neighborhood of the liquid nozzle; and multiple pairs of side face gas ports provided outside of the opening, each pair of the side face gas ports being placed at positions symmetric to each other across a center of the liquid nozzle and being directed toward a center in an injecting direction of the liquid nozzle, and wherein control is made to individually regulate a pressure of the gas to be injected from each pair of the side face gas ports.

A spray device (A) according to the present disclosure includes: a two-fluid nozzle (11) which sprays a mist (91); a spray-device-side gas flow path (12) for supplying a gas to the two-fluid nozzle (11); a gas supply source (17) which supplies the gas to the spray-device-side gas flow path (12); a spray-device-side liquid flow path (13) for supplying a liquid to the two-fluid nozzle (11); a liquid supply source (18) which supplies the liquid to the spray-device-side liquid flow path (13); a pulse-driven liquid flow control valve (14) having a valve opening degree that is adjusted according to a pulse signal to control the flow rate of the liquid in the spray-device-side liquid flow path (13); and a controller (30) which adjusts, in multiple levels, the concentration of the mist (91) sprayed from the two-fluid nozzle 11 by adjusting the valve opening degree of the liquid flow control valve 14.
