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.

A static spray mixer for mixing and spraying two flowable components includes a tubular mixer housing extending in the direction of a longitudinal axis up to a distal end with an outlet opening, having one mixing element arranged in the mixer housing for mixing the components and having an atomization sleeve with an inner surface surrounding the mixer housing in an end region. The atomization sleeve has an inlet channel for a pressurized atomization medium. A plurality of grooves is in the outer surface of the mixer housing or in the inner surface of the atomization sleeve and extend toward the distal end and form separate flow channels between the atomization sleeve and the mixer housing through which the atomization medium flows from the inlet channel of the atomization sleeve to the distal end of the mixer housing. The inlet channel is arranged asymmetrically with respect to the longitudinal axis.

An acoustic force assisted painting system includes a housing, a nozzle, and at least one first transducer. The conduit is configured to receive paint from an external source. The nozzle is disposed in the housing. The nozzle has an inlet that is fluidly connected to the conduit and is configured to receive paint from the conduit. The nozzle has an outlet configured to dispense the paint. The at least one first transducer is disposed in the housing at a location downstream of the nozzle outlet in a flow direction of the paint.

A high-volume low-pressure end effector is presented. The high-volume low-pressure end effector comprises a connection arm and a spray head. The connection arm comprises a housing with flexible conduits running through the housing. The spray head has integral channels configured to receive air and a fluid from the flexible conduits and deliver the air and the fluid to a number of outlets.

In front view of the application nozzle, all of the pressurized air flow K and adhesive flow H are made to run parallel to each other in the vertical direction. Of the pressurized air flows K from the pressurized air hole b in the pressurized air plate, the two that are located on one side of the adhesive hole opening a and from a pair in the front-to-back direction are tilted so as to approach each other. The extension lines thereof are located on the side of the adhesive bead, which results from the adhesive flow discharged from the adhesive hole opening, and have directions that converge. The respective pressurized air flows on the two side of the adhesive bead are made to flow downward while uniting in the direction of convergence. A web in which the adhesive bead is elongated while being swung in the transverse direction is formed and, near the bottom surface of the application nozzle, a non-interference space Q is formed between the adhesive bead and the fore pressurized air flow. The adhesive bead, resulting from the adhesive flow discharged from the adhesive hole opening, and the pressurized air flows do not interfere with each other and walls R of pressurized air flows are formed below the non-interference space Q and on either side of the adhesive bead.

Spray head assemblies, including an air-handling saddle that is attachable to a liquid spray gun platform, a liquid-handling core that is slidably engagable into the air-handling saddle, and an air cap; spray guns using such assemblies; and, methods of using such assemblies.

A static spray mixer for the mixing and spraying of at least two flowable components is proposed having a tubular mixer housing (2) which extends in the direction of a longitudinal axis (A) up to a distal end (21) which has an outlet opening (22) for the components, having at least one mixing element (3) arranged in the mixer housing (2) for the mixing of the components as well as having an atomization sleeve (4) which has an inner surface which surrounds the mixer housing (2) in its end region, wherein the atomization sleeve (4) has an inlet channel (41) for a pressurized atomization medium, wherein a plurality of grooves (5) are provided in the outer surface of the mixer housing (2) or in the inner surface of the atomization sleeve (4) which respectively extend toward the distal end and which form separate flow channels (51) between the atomization sleeve (4) and the mixer housing (2) through which the atomization medium can flow from the inlet channel (41) of the atomization sleeve (4) to the distal end (21) of the mixer housing (2). The inlet channel (41) is arranged asymmetrically with respect to the longitudinal axis (A).

The invention provides an analytic nebuliser device for delivering a sample in aerosolised form, the device comprising a nebuliser nozzle configured to receive a flow of said sample and generate a plume of aerosolised sample spray and a chamber configured to receive a flow of make-up gas and connecting with a plurality of microchannels having outlets arranged around and adjacent to said nebuliser nozzle wherein the microchannels are configured to produce a make-up gas stream with high linear velocity around said aerosolised sample spray to shape and direct said plume. The invention extends to a mass spectrometry or spectroscopy system including the above analytic nebuliser device, to provide in operation the aerosolised sample spray to an ionisation device of the system.

The present invention generally relates to an atmospheric spray process for producing a controlled conical shrouded oxygen gas stream designed to intercept a plasma effluent stream to inject and mix oxygen with powder particles contained in the plasma effluent prior to the molten power particles entrained in the plasma effluent solidifying on a substrate.
