Abstract: An apparatus and method for the spray application of solvent-thinned coating compositions whereby optimum coverage of a substrate with a liquid film is consistently achieved without incurring sagging, run-off or surface irregularities, such as orange peeling, in spite of wide fluctuations in the temperature and/or humidity of the surrounding atmospheric environment. In accordance with the invention, a shroud is provided which is disposed in encompassing relationship around the spray nozzle to which air is supplied at a controlled temperature and/or humidity which envelopes and becomes entrained in the spray forming a controlled localized atmosphere and achieving a controlled vaporization of solvent from the liquid droplets during the course of their travel from the nozzle to the surface of the substrate being coated.

Abstract: A spray nozzle for producing a particularly fine spray of liquid and air comprises a mixing chamber for the liquid and the air, a liquid supply duct terminating within the mixing chamber in a minute, pinhole-like opening of sufficiently small dimensions to produce a fine stream of liquid at high pressure, an abutment placed in the path of the stream to cause the latter to disintegrate and to mix with the air flowing from an air supply pipe, and an outlet orifice disposed in a rotatable cap to receive the mixture from the mixing chamber. The air and liquid sources may be in a common container.

Abstract: A spray nozzle in which a plurality of streams of water under pressure are initially broken up mechanically within a chamber by impingement against a deflector therein and by the shearing action of its knife edge, and are then atomized and initially cooled within the chamber by jets of expanding compressed air, the cooled air and atomized water mixture then being discharged from an annular orifice in the form of a hollow cone spray in which the atomized water is further cooled by reason of the temperature drop in the discharged air because of its expansion upon discharge. This results in the formation of snow flakes where the ambient atmospheric temperature is sufficiently low to effect freezing of the discharged atomized water.

Abstract: A nozzle for mixing a high pressure gas, a liquid fuel and water and finely dividing the latter two is connected in fluid communication with another nozzle facing an impact disperser. The mixture spouted through the latter nozzle collides with the impact disperser to be dispersed into a combustion chamber. A stream adjustment disposed around the second nozzle encircles the disperser to determine an angle at which the finely divided fuel and liquid particles are dispersed in the combustion chamber. Also an apertured paraboloidal surface encircling a nozzle can oppose to a cavity resonator to generate an impulsive wave with a high pressure gas spouted through the nozzle to finely divide liquid particles from that nozzle in the form of an emulsion.

The aerator includes conduit means for conveying water from the water pipe to the shower head. The conveyed water and the drawn in ambient air are mixed by the normally occurring water turbulence within the shower head prior to ejection of the mixture through the shower head nozzles.

Abstract: A nebulizer having an elongate housing supporting an air nozzle in aspirating relation to a liquid nozzle in an interior chamber of the housing to vaporize the liquid. Baffle discs each having a chordal section removed therefrom are placed in parallel spaced relation in the chamber substantially transverse to the direction of vapor flow in the chamber. The openings formed by the chordal sections of adjacent discs are non-aligned causing the vapor flow to follow a tortuous path, and impinge upon a baffle surface, collapsing larger liquid droplets in the vapor which collect in the chamber. A liquid flow control valve in one position connects the liquid nozzle to the accumulated liquid in the chamber, or to an external reservoir, and in a second position, to an exterior source of liquid.

Abstract: An atomized fuel-air mixture is obtained in a heartshaped chamber of a rotating member which is mounted in the combustion air inlet duct of an internal combustion engine. Fuel and a gaseous medium are injected into the chamber and are thoroughly mixed by a fuel flow dividing portion formed by the curved walls of the chamber in axial alignment with the fuel injection nozzle, which deflects the fuel flow from the axis of rotation towards the periphery of the chamber. Outlet channels exhaust the fuel-gaseous medium mixture from the chamber and impart a rotational force to the member.

Abstract: A method and an apparatus for the combustion of high viscosity low grade liquid fuel (e.g., residual oil), in which the fuel is directed through an ejector into an impact chamber in which it impinges upon a baffle with the rebounding fuel particles being further pulverized by jets of air introduced into this chamber with an inclination to the axis of the burner. The resulting fuel-air mixture passes around the impingement baffle with a laminar flow of air passing axially along the wall of this chamber and preventing precipitation of fuel droplets thereon. Upon emergence from the chamber the fuel-air mixture encounters a flow of air passing along the exterior of the impact chamber and intercepted by a plurality of inwardly extending steps which furtherpromote pulverization and mixing.

Abstract: A device is provided for moistening the plate cylinders of offset printing machines. The device includes an inner rotatable sleeve having an air passage extending therethrough. Angularly extending passages are provided in the inner sleeve. The inner sleeve is rotatable within an outer fixed cylinder having spaced apertures all directed in the same direction.
