Abstract: Nozzles for discharging high velocity air are positioned on either side of an aircraft engine exhaust duct exit. High velocity air is discharged tangential to an outer surface of each nozzle and follows the contour thereof. The nozzles are positioned so that when the high velocity air separates from the outer surface of the respective nozzles, it flows outwardly relative to the aircraft's fuselage structure. The high velocity air from the nozzle closest to the aircraft's fuselage structure impinges on the exhaust gas stream, deflecting the stream away from the fuselage. The high velocity air from the nozzle furthest from the fuselage creates a low pressure area which deflects the exhaust gas stream away from the fuselage. In combination, the two nozzles deflect the exhaust gas stream away from the fuselage to a significant degree.

Abstract: A spray nozzle member jets out paint in a fan-shaped pattern. Air streams are jetted from a conically annular center air nozzle in such a way as to surround the fan-shaped pattern, whereby a conically atomized spray pattern is discharged from a deformed opening. Notches formed on the deformed opening cause the conical pattern to spread, and fan-shaped air streams produced by air from auxiliary air nozzles promote the spreading of the spray pattern to a greater extent. Oblique air streams are forwardly supplied from side air nozzles into that pattern, so that a fan-shaped spray pattern is again produced. Paint under a pressure of several kg/cm.sup.2 is discharged from a spray nozzle. An atomizing air stream, except the part thereof corresponding to the edge of the fan-shaped spray, converges on the front extremely close to the spray nozzle. The atomizing air stream is discharged under a pressure of less than 2 kg/cm.sup.

Abstract: An improvement in reduction of particle size of painting and coating particles is achieved by providing a tapered channel(s) in the cylindrical wall radially of the spray apparatus' nozzle head, which is a wall adjacent the nozzle outlet slit.

The tapered channel(s) extends radially inwardly from an air inlet opening on the exterior face of the wall, fully through the wall, and into a downstream air outlet opening on the interior of the wall face, the tapering of the channel being of a downstream size-reducing nature.

A slot nozzle die has elongated air slots along a vertically oriented slot extrusion opening. A hot melt or wax gun is disposed above the bottle neck to apply a bead of adhesive to the bottle top. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow and is continued beyond that point in time, when the hot melt flow ceases. The air carries a film of coating material horizontally to the bottle neck. Means are provided for spinning the bottle about its vertical axis. The delays between the operations of the air flow and the coating flow are on the order of micro seconds. The merged coatings are heated to smooth the coating finish to produce a traditional neck seal.
