20080314314 | ULTRASONIC SPRAY COATING SYSTEM - Disclosed is an ultrasonic spray coating system comprising an ultrasonic spray head with integrated fluid delivery system (IFDS), which consists of an ultrasonic transducer with a spray forming tip, an ultrasonic generator, an external liquid applicator, a precision liquid delivery system and air directors. The coating liquid is delivered to the spray forming tip on the ultrasonic transducer from an external liquid applicator. The liquid is stored in a pressurized reservoir and fed to the liquid applicator by a precision liquid delivery system. The ultrasonic vibrations of the spray forming tip break up the liquid into small droplets and propel them from the tip in the form of a spray. The spray produced with ultrasonic energy alone is a very narrow “sheet-like” pattern. The width of the spray pattern produced is equal to the width of the spray forming tip (2 mm to 4 mm). Air directors are used to produce air streams to further shape and accelerate the ultrasonically produced spray. Air directors can be used to produce three distinct spray patterns, based upon the nature and placement of the air stream—narrow mode spray pattern; wide mode spray pattern; or side mode spray pattern. | 12-25-2008 |

20110253040 | Apparatus For Forming Composite Membrane With Porous Coating Layer - The present invention discloses a method for forming a composite membrane with a porous coating layer. At first, a filling process is carried out to fill the pores of a porous substrate with a liquid. Next, a raw material is transformed into melt or incomplete melt droplets by a heating source and the droplets are sprayed to the surface of the porous substrate filled with the liquid. The liquid is evaporated by the high temperature droplets and plasma flame to become vapor and the vapor breaks through the droplets to have the droplets sputter into different blocks to thereby form random and dispersed flat particles after cooled. Flat particles are formed and stacked continuously so as to form a composite membrane with a porous coating layer. Moreover, the invention provides an apparatus for forming a composite membrane with a porous coating layer. | 10-20-2011 |
