  • Patent number: 7275446
    Abstract: A method and apparatus are provided for measuring the crushing strength of an abrasive, comprising particles, used in a lapping process. Embodiments include a crushing strength tester having a cup for holding the abrasive; a first motor for rotating the cup in a first direction; a piston having a face for rotatably fitting within the cup and contacting the abrasive; a second motor for rotating the piston in a second direction opposite the first direction; and a press for pressing the piston against the abrasive and crushing the particles while the first and second motors are rotating. An initial particle size distribution for the particles is determined, then the abrasive is subjected to a crushing force approximately equal to that of the lapping process using the crushing strength tester. A post-crushing particle size distribution for the particles is determined, and the initial and post-crushing particle size distributions are compared.

  • Publication number: 20060083783
    Abstract: A method of treating metabolic syndrome in a human diagnosed with metabolic syndrome by administering a therapeutically effective amount of fenofibrate over a treatment period. The results can include identifying a human as not having clinical metabolic syndrome after treatment, as compared to having metabolic syndrome before treatment.

  • Patent number: 6602108
    Abstract: A system and method are disclosed for preparing platens to perform lapping operations. The system includes a platter that is rotatably mounted on a base and designed to receive the platen thereon. A main drive motor is provided for rotating the platter and the platen disposed thereon. A plurality of pressure arms are disposed on the base and configured to include a tool receiving portion that can be positioned in alignment with a lapping surface of the platen, and configured to softly touch a tool to a platen. A tool is attached to each tool receiving portion so that predetermined operations can be performed on the lapping surface of the platen. A monitor is provided to monitor predetermined parameters and maintain substantially constant conditions while preparing the platen.
