Patents by Inventor Mark T. Rubel

Mark T. Rubel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Device to equalize steam quality in pipe networks
    Patent number: 5407274
    Abstract: Steam quality at both outlets of a T junction is equalized by a static mixer immediately adjacent the inlet to the junction causing substantial homogenization of the liquid and vapor phases of wet steam entering the junction so that the steam exiting both legs of the junction will have substantially the same quality as the steam entering the junction.
    Type: Grant
    Filed: February 22, 1994
    Date of Patent: April 18, 1995
    Assignee: Texaco Inc.
    Inventors: Edward A. Woerheide, James R. Stoy, Mark T. Rubel
  • Device to equally distribute the vapor and liquid phases during wet steam flow through branch tee junctions
    Patent number: 5251662
    Abstract: Steam quality at both outlets of a T junction is maintained equal to that of the inlet by variably controlling the pipe cross sectional area according to the ratio of vapor flow rates through the respective outlet legs.
    Type: Grant
    Filed: October 19, 1992
    Date of Patent: October 12, 1993
    Assignee: Texaco Inc.
    Inventors: Mark T. Rubel, James R. Stoy
  • Method and apparatus for controlling phase splitting at pipe junctions
    Patent number: 5250104
    Abstract: Separation of wet steam into its liquid and vapor phases is facilitated prior to encountering a junction. The separated phases are recombined as the steam exits the respective arms of the junction.
    Type: Grant
    Filed: October 16, 1992
    Date of Patent: October 5, 1993
    Assignee: Texaco Inc.
    Inventors: Eric L. Berger, James R. Stoy, Mark T. Rubel, James L. G. Schrodt
  • Method and apparatus for eliminating unequal phase splitting at piping junctions
    Patent number: 5218985
    Abstract: The separation of wet steam into its liquid and vapor phases, prior to encountering a pipe junction, is facilitated. The liquid phase is then recombined by aspiration to effectively behave as a single phase vapor of homogeneous density at the point where the flow stream is divided by the junction.
