Abstract:
A nozzle spray assembly for insecticide made in two halves that are connected together and define an internal reservoir. The lower half has an arcuate shaped exterior surface and includes an inlet tube in communication with the reservoir. The lower half also has nozzle openings adjacent the arcuate surface so that when air is directed over the arcuate surface past the nozzle openings fluid is sucked into the inlet tube and reservoir and out the nozzle openings to spray insecticide onto the surrounding area.

Abstract:
A fluid mixing device includes a nozzle having a first element mounted therein, and connected to a hollow, tubular element having a series of openings formed therein adjacent the first element. The hollow, tubular element extends outwardly from the nozzle, through an exit opening and may have a second element mounted thereon. The second element may take various shapes, including having a number of protrusions thereon, to vary the atomization of fluid flowing from the nozzle exit. An outer end of the hollow, tubular element may be free to suck in atmosphere, or may be attached to a tube immersed in a container, to draw in a second fluid to mix with the first fluid through the nozzle.
Abstract:
The micro-atomizing device of the present invention creates high energy vortices. These high speed vortices are generated simultaneously and synchronously and then merged into a three dimensional force field. When the high energy vortices are brought together, a large vacuum is produced in a resultant stable vortex force field in a vortex accumulation zone. The high vacuum draws the fluid to be atomized through a delivery tube into the vortex accumulation zone. The high energy within the vortex accumulation zone either breaks up the fluid to be atomized into very small droplets or gasifies the fluid by the combination of high energy density cold boiling, shockwave generated ultrasound, and centripetal forces.
Abstract:
Systems, methods and apparatus are provided through which in some implementations a pneumatic ported atomizing fluid delivery manifold includes a fluid delivery housing, the fluid delivery housing having a frustum geometry, the fluid delivery housing has a first end and a second end, the first end has a first plane and the second end having a second plane, the fluid delivery housing has at least one chamber through which cleaning solution is operable to pass from the first end to the second end, and a free-floating pneumatic rotating exit tube positioned along a longitudinal center axis of the fluid delivery housing, the free-floating pneumatic rotating exit tube has only air passing through the free-floating pneumatic rotating exit tube, wherein fluid from the fluid delivery housing and the air from the free-floating pneumatic rotating exit tube are mixed together creating a fine mist in a rotational motion.
Abstract:
The method for flame spraying thermoplastic powders provides to heat the article to be coated at a suitable working temperature and to feed the said thermoplastic powders, transported by an inert gas, a flow of compressed air and a flow of liquefied petroleum gas through respective separated discharge chambers (7, 9, 12), shaped inside a mixing device (1) of a spray gun. The thermoplastic powders are then projected, in a resulting flow (30), on the heated surface of the article to be coated, to determine the melting of the same powders at their contact with said heated surface. At least one couple of flows (31, 32) of compressed air is sprayed converging towards the resulting flow (30) flowing out of the mixing device (1), giving the resulting flow (30) a substantially flattened fan shape.
