  • Patent number: 8408049
    Abstract: An apparatus and method to determine fractions of various phases in a multiphase fluid. The apparatus includes main body including an interior configured receive a multiphase fluid and an exterior. The apparatus senses fluid pressure of multiphase fluid received in the interior and senses a fluid temperature of the multiphase fluid. The apparatus transmits an ultrasonic wave into the fluid and detects the transmitted wave to determine its velocity and attenuation. The apparatus may adjust the determined velocity and attenuation based on the temperature and pressure of the fluid to compensate for a difference between the sensed temperature and pressure and a standard temperature and pressure. The apparatus determines a gas fraction, water fraction, and a non-water fluid fraction of the multiphase fluid based on the sensed fluid pressure, the sensed fluid temperature, and the velocity and attenuation of the ultrasonic wave in the multiphase fluid.

  • Patent number: 5228445
    Abstract: The invention involves a treatment process for improving the intrinsic quality of bone in osteoporotic patients. This can reduce the frequency of spinal fractures by inducing formation of bone which is mechanically stronger than that which it replaces. The process preferably comprises: administering an enteral form of sodium fluoride to maintain an individual's serum fluoride level from about 100 to about 200 ng/ml with a circadian fluctuation of less than about 75 ng/ml, and dietarily supplementing said individual with absorbable calcium (preferably calcium citrate). In one embodiment, sodium fluoride administration is interrupted temporarily (for about 30 to about 60 days in a 13 or 14 month cycle) to prevent loss of fluoride effectiveness and avert impaired mineralization of bone. Calcium is preferably maintained by an enteral dose of about 400 mg calcium twice daily. A vitamin D preparation may also be administered to the individual to further enhance bone strengthening.
