A kit for a spray gun including a sleeve delimiting an inner volume provided to contain a pressurized fluid, the sleeve being configured to be connected to a main body of a spray gun, the sleeve having a radial periphery delimiting a fluid outlet of the sleeve and at least one orifice emerging on the radial periphery and fluidly connecting the inner volume and the radial periphery, a connector having an intake end connected to the fluid outlet and a connecting end suitable for being connected to a cup so as to fluidly connect the cup to the inner volume of the sleeve, and a ring surrounding the sleeve and covering the fluid outlet outside the intake end of the connector.

A nozzle assembly includes a nozzle, a manifold, and wand body. The nozzle, manifold, and wand body can be coupled together to provide a robust spray drying system that can withstand elevated temperature and/or pressure feed stock. In some embodiments, an internal shoulder portion of the manifold can engage with a side of a nozzle collar to restrict distal movement of the nozzle relative to the manifold.

Aspects of the present disclosure describe a two-fluid nozzle including a nozzle body. The nozzle body includes a first fluid nozzle tip having a first fluid opening formed therein. The nozzle body includes a second fluid nozzle tip comprising a second fluid opening formed therein. The first fluid nozzle tip and second fluid nozzle tip can be fluidically isolated from each other in the nozzle body. The first fluid opening and second fluid opening are each arcuate and rectangular. The second fluid opening is positioned adjacent to the first fluid opening such that, when flowing, the second fluid from the second fluid opening affects the first fluid from the first fluid opening of a first tubular member.

A system for spraying hot-melt adhesive onto glued surfaces comprising a melter to heat hot-melt adhesive, an air compressor, a power and control system and a gun. The gun is connected to the melter by a pipe with screw connectors, through which a hot-melt adhesive being heated flows, and the air compressor by an air pipe with screw connectors through which a pressurized compressed air flows. The gun has a nozzle with a hot-melt adhesive outlet or orifice and a compressed air outlet. The pipe through which flows the hot-melt adhesive having a viscosity between 2500 mPa.Math.s and 7000 mPa.Math.s and a temperature between 120 C. and 200 C., and a density between 0.8 kg/dcm.sup.3 and 1.4 kg/dcm.sup.3, and the air pipe are fitted in an insulating layer of a hose.

Provided are air caps for liquid spray head assemblies and/or for liquid spray guns. Specifically provided are molded air caps with face geometry inserts. Face geometry inserts provided herein may be effective to provide refined spray patterns. The face geometry inserts are components that are self-aligning in that location, size, and spacing of air and/or liquid openings are designed into in a single piece. The air caps comprise a base member comprising: a base member body, at least one pair of exit air openings, a nozzle tip opening; and a face geometry insert comprising a pair of shaping air apertures and being retained to the base member body.

A portable ultrafine nebulizer comprises a housing, an atomizing nozzle located at the front port of the housing, an air turbine deposited inside the housing, an air flow guide device fixed at the front port of the housing, and a water pump for pumping liquid; the air flow guide device is provided with a plurality of air flow guide blades distributed uniformly around the periphery of the atomizing nozzle, and each of the air flow guide blades is provided with a guide surface; in the atomizing nozzle is provided with a spiral channel and a fluid channel communicated with the water pump, the atomizing nozzle is provided with a spray port at the front end, and the spray port is communicated with the fluid channel through the spiral channel; the air turbine, the air flow guide blades and the spray port are distributed successively along the airflow direction.

An air cap arrangement and a spray gun. The air cap arrangement comprises an air cap, an air cap ring and a retaining ring. The air cap ring comprises a groove configured to extend on the circumferential inner surface of the air cap ring. The air cap also comprises a groove configured to extend on the circumferential outer surface of the air cap, and the retaining ring is arranged in the groove of the air cap ring and the groove of the air cap to limit the axial movement of the air cap within the air cap ring.

The present invention relates to a spray dried plasma composition having one or more of the following characteristics: when reconstituted, largely amorphous and has no cholesterol crystals; when reconstituted, the number of large particulates is reduced; has low residual moisture; reconstitutes rapidly in under four minutes; highly stable when stored under refrigeration, at room temperature or at elevated temperatures and allows for storage for longer periods of time; when reconstituted, exhibits recovery of the most fragile of proteins, including von Willebrand's factor; when reconstituted with Sterile Water for Injection (SWFI), reconstituted plasma is at a pH that is near normal plasma pH, and does so without treatment or storage in CO.sub.2 or other pH adjustment; and when reconstituted, has reduced complement activation (C5A, C3A).

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.

A coating device comprises at least one application apparatus to discharge a coating agent from at least one coating agent nozzle. The application apparatus is configured to apply an oscillation to at least one of the coating agent and at least one coating agent jet such that at least one of the coating agent and the at least one coating agent jet break up into droplets.
