Patent number: 7945395Abstract: The actual density of liquids is determined with a flexural oscillator that is excited at two different natural vibrations. The presence of air/gas inclusions or other inhomogeneities in a liquid is detected and their influence can be eliminated. In an initial step, the periods of the inherent vibrations and of at least one vibration damping value of the natural vibrations are determined for liquids having different densities ? and viscosities. Liquid densities as well as the difference between them and between the vibration damping values are determined from this. An inclusion-free curve (KB) which reflects the functional dependence F(??) between the relative density differences and the vibration damping differences is calculated and the exact function determined; i.e. the gas/air inclusion-free curve (KB) is expanded by introducing a deviation bandwidth (ab) to form an inclusion-free curve area (KF), which is stored.Type: GrantFiled: November 13, 2008Date of Patent: May 17, 2011Assignee: LABOR FUER MESSTECHNIK Dr. Hans Stabinger GmbHInventors: Helmut Heimel, Ulrike Rakusch, Klaus Ritzmann, Hans Stabinger

Publication number: 20100185401Abstract: A computer system and method for predicting the aqueous phase CO2 corrosion rate of a pipe useful in the production and transportation of oil and gas. Input parameter values corresponding to water chemistry and physical fluid and pipe properties are received. Based on these input parameter values, the system and method derive current-voltage relationships for multiple cathodic reduction reactions according to an electrochemical model of the corrosion reaction, and a current-voltage relationship for the anodic oxidation reaction of iron dissolution. A current density is obtained, at the intersection of an extrapolation of the anodic current-voltage relationship and an extrapolation of the summed cathodic current-voltage relationships. The predicted corrosion rate is then calculated from the obtained current density. The effects of secondary parameters such as scale and flow regime, and the efficacy of a corrosion inhibitor, can also be evaluated.Type: ApplicationFiled: January 18, 2010Publication date: July 22, 2010Inventors: Sandra E.

Publication number: 20100082264Abstract: A method for providing a more accurate synthetic profiles of temperature, salinity and sound speed of the ocean over an area of interest is provided by using a value of the mixed layer depth in addition to values of surface temperature and surface height in an ocean modeling system such as the Modular Ocean Data Assimilation System (MODAS) system developed for the U.S. Navy. The method of the present invention compares the predicted or observed mixed layer depth for the area of interest, for example, as obtained from remote sensing or upper ocean modeling, to a mixed layer depth estimated from an initial synthetic profile, and determines which is deeper, termed the reference mixed layer depth. The method then derives a modified temperature and salinity synthetic profile by setting the temperature and salinity equal to the surface values at depths less than or equal to the reference mixed layer depth and using an algorithm to estimate temperature and salinity at depths below the reference mixed layer depth.Type: ApplicationFiled: September 29, 2008Publication date: April 1, 2010Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Charlie N.
