  • Patent number: 6156120
    Abstract: 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.

  • Patent number: 6110505
    Abstract: The invention provides an essentially translucent liquid antacid composition with dihydroxyaluminum sodium carbonate (DASC) as the active ingredient. The DASC is prepared by co-drying DASC with a polyol, and the resulting co-dried DASC/polyol is mixed with water to form the liquid composition. The antacid composition preferably contains additional polyol to further improve the translucency of the liquid composition.

  • Patent number: 6041020
    Abstract: 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.

  • Patent number: RE36516
    Abstract: A filter for fluids includes a pair of layers or multiple layers or pairs of material joined together to form a laminate having a fluid contacting surface. A plurality of spaced pockets is formed between the layers of material in the contacting surface. The layers of material are fluid permeable at the pockets whereby fluid may flow through the laminate at the pockets. The fluid contacting surface is fluid impermeable except for the pockets to require the fluid passing through the laminate to be confined to flowing through the pockets. Filter members are in the pockets for removing any contaminants from the fluid. Alternatively, additive materials such as powdered cream or sugar in the pockets dissolve in the fluid passing through the pockets to enhance the fluid.
