Patent number: 6156120Abstract: The present invention relates to an apparatus for the uniform distribution of a small amount of liquid on bulk materials. The method is performed by spraying the liquid with at least one ultrasonic nozzle onto the bulk material, which is finely particulate. The spraying may occur before, during, or both before and during, mixing the particulate solid in a mixing apparatus. Dust may be significantly reduced by the apparatus of the instant invention, and the apparatus is useful for applying not only liquids, but emulsions, solutions, dispersions, or melts. The mixer may be mechanical or pneumatic.Type: GrantFiled: April 29, 1996Date of Patent: December 5, 2000Assignee: AventisInventors: Stefan Heffels, Johannes Hartel, Gerhard Noltner, Peter Mischke

Patent number: 6041020Abstract: The investigation, development and application of a laser-based ultrasonic inspection system to the problems of evaluating polymer/graphite composite materials has been realized. The use of lasers to generate and detect ultrasonic waveforms in materials provides a means to detect material properties remotely. The study consisted of three main aspects: 1) A confocal Fabry-Perot (CFP) based system has been devolved which uses light reflected from the CFP interferometer to derive the ultrasonic signal. This allows higher frequency components of the detected waveforms to be discerned when compared to a CFP-based system using light transmitted through the CFP interferometer. 2) Thermoelastic and ablative laser generation of acoustic pulses in polymer/graphite composite materials has been investigated. Thermoelastic generation of ultrasound occurs when thermal energy deposited by a pulsed laser creates a localized expansion in the material.Type: GrantFiled: April 21, 1997Date of Patent: March 21, 2000Assignee: University of DelawareInventors: James N. Caron, James B. Mehl, Karl V. Steiner
