  • Methods and apparatus for ultrasonic cleaning
    Patent number: 8709338
    Abstract: The present invention relates to a method of cleaning a surface by applying highly propagating ultrasonic energy to said surface, the method comprises immersing at least a portion of the surface into a fluid, wherein said fluid is in contact with an highly propagating ultrasonic energy emitting assembly; and emitting highly propagating ultrasonic energy from the assembly into the fluid to generate cavitation at the surface thereby cleaning said surface.

  • High energy ultrasound extraction method and apparatus
    Patent number: 8343562
    Abstract: The present invention describes a method and apparatus for aqueous extraction of chemical compounds from solid material in which the solid material is entrained in an extraction liquid phase that flowed around immersed sonotrodes emitting radial or focused high energy ultrasonic waves. A significant increase in extracted material and decreases in extraction time is observed.
