  • Ultrasonic system for on-line monitoring of pressed materials
    Publication number: 20060266119
    Abstract: A method and apparatus for monitoring the quality of a material during die press manufacture. The material may be powder, a powder and binder mixture, a fluid or melted polymer or other material suitable for press manufacture. The method includes measuring a wave attribute of one or more ultrasonic waves transmitted through the material during or in certain instances before compaction. Information is derived from the measured wave attribute regarding a quality of the compaction of the material. The information regarding the quality of the compaction of the material may include but is not limited to, the density of the material, the uniformity of the material density, changes in the composition of the material, or the degree of consolidation of the material.

  • Ultrasonic monitor of material composition and particle size
    Patent number: 7047809
    Abstract: A method and apparatus for determining the composition of a containerized material, typically a suspension, through which ultrasonic waves are passed. The component ratios and particle sizes of a stationary or flowing material are determined by measuring ultrasonic wave phase and attenuation changes at multiple frequencies and deriving shape features from curves of the phase or attenuation versus frequency. Preferably, the frequency range employed extends below and above the frequency of maximum attenuation of the expected mean particle size in a suspension. The material composition is derived from analysis of the shape features of the derived curves.
