Abstract: A spray generator has a gas duct (1, 6, 10, 14, 16, 21) from which issues a stream of gas in various configurations according to the shape of the delivery end. Liquid is directed by nozzles (3, 11) or other means (13, 18, 22) transversely into the gas stream, although it may have a directional component going with that stream and/or a component to generate swirl. The relative speeds and amounts of gas and liquid cause the liquid to break up into droplets (9, 24) which form discrete clusters (5, 8) in a compact spray pattern. Secondary gas streams (17, 23) can be applied further to shape the spray pattern.

Abstract: An advantageous improvement (10, 12) as to reduction of particle size of painting and coating particles is achieved by providing a tapered channel(s) (36, 36 x ) in the cylindrical wall (30) radially of the spray apparatus' nozzle head (14), which is a wall adjacent the nozzle outlet slit (34) of prior art apparatus. As a novel application of the "Bernoulli Principle", its venturi feature achieves a movement and acceleration of ambient air to intermix with the paint particles being dispensed through the nozzle outlet slit (34). The tapered channel(s) (36, 36 x ) extends radially inwardly from an air inlet opening (38, 38 x ) on the exterior face of the wall (30), fully through the wall (30), and into a downstream air outlet opening (40, 40 x ) on the interior of the wall face, the tapering of the channel (36, 36 x ) being of a downstream size-reducing nature.

Abstract: The device comprises means (3i, 4) in an enclosure (1) for bringing the liquid to an elongate spray nozzle (7) in the wall of the enclosure, and means for injecting gas into said enclosure to spray the liquid fed to the nozzle by driving it out of said enclosure. An elongate element (5) is provided in the enclosure to receive the liquid from the feed means. Said liquid is spread over a convex surface (51) of said element and is then carried off by the gas and flows to two elongate slits (81, 82) adjacent to the nozzle (7) and converging towards the latter. The width of these slits varies periodically and interdependently over their length to form two sheets of the liquid/gas mixture which come together at the nozzle (7) to form at its outlet a mist of liquid confined within an angle ((alpha)) from the nozzle. Application in cooling steel blooms or aluminum sections.

Abstract: A process and apparatus are provided for injecting dry lightweight particulate material into a stream of catalyzed resin. The particulate material is stored in a fluidizing tank (62). The fluidized dry particles are conveyed from the tank (62) under a controlled vacuum created by a low pressure venturi pump (84) through an anti-static conveying tube (112) to an adjustable delivery tube (36) which terminates with a nozzle (52). The nozzle (52) delivers a low velocity controlled spray pattern (50) which coincides with the stream of pressurized resin. Within the venturi pump (84) and opposite to the main low pressure, low volume inlet (102), is a second pressurized inlet (100). This inlet (100) directly controls the degree of vacuum, thereby precisely determining the amount of particulate material delivered to the resin stream. The degree of vacuum can be sensed by a tube (156) connected to the venturi pump (84), and through electronic circuitry is converted to a visual display (160).

Abstract: A stream of molten metal particles in a metal spraying apparatus is deflected from side to side by gas issuing from two nozzle blocks disposed at diametrically opposite sides of the stream. Gas is supplied to the two nozzle blocks (13) alternately under the control of a rotary valve (19) having a stator (18) and a cylindrical rotor (24). The rotor has two circumferentially extending grooves (26) whose cross-sectional area varies in predetermined manner and each of which serves to provide and cut off communication between an inlet port (21) for gas under pressure and an outlet port (23) which is circumferentially aligned with the inlet port and which leads to an associated one of the nozzle blocks. The areas of the inlet and outlet ports are each greater than the maximum cross-sectional area of the groove, so that the quantity of gas reaching the nozzles at each instant is determined by the instantaneous effective area of the groove (26). The limiting quantity of gas emitted from the nozzles corresponding to maximum deflection of the metal particle spray is however determined by the total area of the nozzles in the block. An increase in the quantity of gas issuing from the nozzles increases the deflection of the metal particle stream.
