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 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.

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.

Abstract: An improved system for continuously detecting and correcting the display in a cathode ray tube for errors in size and linearity. The system employs a crystal oscillator as a reference frequency to determine absolute error which is represented as "size" on the display screen, and relative error which is represented as linearity. The error is determined from the index pulse feedback, which is an output of a phase lock loop voltage controlled oscillator which is compared to the reference frequency to provide an error voltage level. This output level is then digitized and processed in terms of general control, interpolation, extrapolation, filtering, etc., testing, and stored in digital memory. The digital error data is converted back to analog levels for insertion into a horizontal auxiliary amplifier circuit for linearity correction. A main horizontal amplifier circuit receives size correction.

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.
