Abstract: A nozzle assembly that produces a cone-shaped spray pattern of entrained liquid droplets is disclosed. The nozzle includes an ultrasonic atomizer for atomizing a liquid on an atomizing surface located at the end of an atomizing stem. The nozzle assembly is supplied pressurized air that is directed to the atomizing surface by intercommunicating ports, chambers and/or channels. To provide the cone-shaped spray pattern, the ports, chambers and/or channels cause or direct the pressurized gas to rotate about the atomizing stem. When the rotating pressurized gas exits the nozzle assembly via proximate the atomizing surface, atomized liquid droplets become entrained in the gas. The rotating pressurized gas propels the droplets forward and moves at least some droplets circumferentially outward in the cone-shaped spray pattern. In various embodiments, the pressure of the gas can be adjusted to control the size and shape of the cone-shaped pattern and the distribution of droplets.

Abstract: The nozzle effects three stages of liquid atomization. The first stage is carried out by means of a single liquid orifice and an expansion chamber containing an impingement pin. A high velocity stream of liquid is discharged through the liquid orifice and is broken-up upon striking the flat end of the impingement pin. The second stage is produced by an air guide which reduces in area to form jets of air into a high velocity annular air curtain, the curtain passing through the liquid orifice in surrounding relation with the liquid stream and striking the broken-up flow of the first stage to atomize the particles. The mixture is then allowed to expand in the expansion chamber to reduce the tendency of the liquid particles in the atomized mixture from commingling together and reforming into larger particles. The third stage is effected by the expansion chamber and by multiple discharge orifices. The mixture is sprayed from the expansion chamber through the multiple orifices and, upon being discharged into the atmosphere, the particles are atomized further due to the release of pressure formed inside the expansion chamber.

Abstract: Apparatus in which water and liquid detergent meet in a venturi chamber to be commingled there, the detergent being drawn into the venturi by the condition of unbalanced (lowered) pressure there resulting from the velocity of the water flowing through the venturi throat. Compressed air is introduced into a nozzle in communication with the venturi, and the commingled water, detergent, and air are then discharged for use in the form of a foam. The water inlet includes a removable insert separate from the venturi, the upstream end of the insert being exposed for direct accessibility for a mounting tool, and an annular chamber located upstream from the discharge end of the venturi outlet initially receives the compressed air which is then caused to be discharged in an annular condition about the commingled detergent and water flow.

Abstract: A spray nozzle assembly that utilizes ultrasonic atomization techniques to atomize a liquid into a cloud of small or fine droplets is disclosed. The nozzle assembly also can use various air or gas atomizing technologies to propel the generally directionless droplet cloud toward a surface or substrate to be coated. The propelled droplet cloud may at this state have a conical or cone-shaped spray pattern. Additional air or gas atomizing technologies can be utilized to shape the propelled droplet cloud into a flattened fan-shaped spray pattern that can be usable in various industrial applications. The shape of the spray pattern and the distribution of droplets within the pattern can be adjusted by manipulation of the gas pressure used in gas atomization.

Abstract: A spray head having a body provided with separate inlets for two fluids, the inlets having a common longitudinal axis and being in end abutting relation. One inlet leads to a chamber for receiving one of the fluids, the chamber being provided with means through which the fluid is discharged, and the other inlet leads to a post, manufactured simultaneously with the manufacture of the chamber and integral with the body. The post is located in the chamber and is hollow so that the other fluid is discharged therefrom by the aspirating action of the first, and the two fluids are commingled, the second fluid being atomized by the first. Various nozzle structures are disclosed from which the commingled discharges flow, the ultimate discharge being in the form of a cone, or a flat fan by the employment of opposed supplemental fluid jets, or non-circular in formation as shaped by appropriate terminus aperturing, or flattened and diverted by impact with an impingement surface in the path of the discharge.

Abstract: A method and apparatus for diminishing display transients and jitter. The method and system disclosed utilizes prior illumination and position histories in displaying and illuminating representations, and elements comprising the representations, on the display. Recognizing repeated representations, finding their prior and current positions, and determining if the difference in position is over a threshold value, diminishes the jitter by displaying the representation in the new position if over the threshold value, or, if it is not over the threshold value, then displaying it in the prior location. The illumination of an element at an intensity, which is based on prior illuminations and/or intensities of the element, diminishes the transients by avoiding flashing or flicker of transient illuminations.
