Patents by Inventor Robert A. Beddome

Robert A. Beddome 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).

  • Patent number: 5564290
    Abstract: A cryogenic rectification system for producing elevated pressure gaseous oxygen wherein pressurized liquid oxygen is vaporized against pressurized working fluid which is then turboexpanded to form a dual phase stream having both vapor and liquid fractions.
    Type: Grant
    Filed: September 29, 1995
    Date of Patent: October 15, 1996
    Assignee: Praxair Technology, Inc.
    Inventors: Dante P. Bonaquist, John H. Ziemer, Cheryl A. Engels, James B. Wulf, Robert A. Beddome
  • Patent number: 5398514
    Abstract: A cryogenic rectification system wherein feed partially traverses the primary heat exchanger, thereafter is turboexpanded, and then traverses another portion of the primary heat exchanger reducing the temperature differences between approaching streams within the primary heat exchanger and thus the cycle irreversibilities resulting in lower power requirements.
    Type: Grant
    Filed: December 8, 1993
    Date of Patent: March 21, 1995
    Assignee: Praxair Technology, Inc.
    Inventors: Mark J. Roberts, Neil M. Prosser, Robert A. Beddome
  • Patent number: 5386691
    Abstract: A cryogenic air separation system wherein a portion of the feed air is condensed against vaporizing product from the air separation plant and at least some of the vaporized bottom liquid from the higher pressure column is withdrawn from the system, bypassing the lower pressure column thereby increasing the L/V ratio in the upper portion of the lower pressure column to compensate for reduced liquid in that column caused by the feed air liquefaction.
    Type: Grant
    Filed: January 12, 1994
    Date of Patent: February 7, 1995
    Assignee: Praxair Technology, Inc.
    Inventors: Dante P. Bonaquist, Robert A. Beddome, Michael J. Lockett
  • Patent number: 5365741
    Abstract: A cryogenic rectification system wherein compressed feed is further compressed in a compressor coupled to a turboexpander and turboexpanded through the turboexpander to drive the compressor, and a portion of the feed which does not undergo turboexpansion is condensed against liquid oxygen in a product boiler.
    Type: Grant
    Filed: May 13, 1993
    Date of Patent: November 22, 1994
    Assignee: Praxair Technology, Inc.
    Inventors: Mark J. Roberts, Robert A. Beddome, Dante P. Bonaquist
  • Patent number: 5282365
    Abstract: An improved packed column distillation system, which may be particularly advantageous for use with cryogenic distillation such as the cryogenic distillation of air, wherein external heat is provided at the column wall, especially at a stripping section of the column, to vaporize liquid formed on the inner surface of the column wall resulting in improved separation efficiency with lower packed bed height.
    Type: Grant
    Filed: November 17, 1992
    Date of Patent: February 1, 1994
    Assignee: Praxair Technology, Inc.
    Inventors: Richard A. Victor, Dante P. Bonaquist, Robert A. Beddome
  • Patent number: 5231835
    Abstract: Dual turbine-booster compressor units are arranged for advantageous liquefaction operations using high pressure heat exchangers.
    Type: Grant
    Filed: June 5, 1992
    Date of Patent: August 3, 1993
    Assignee: Praxair Technology, Inc.
    Inventors: Robert A. Beddome, Joseph A. Weber
  • Patent number: 4560398
    Abstract: A double column air separation process which enables one to efficiently produce oxygen gas at a pressure exceeding that of the lower pressure column without compression or pumping wherein oxygen liquid hydrostatic head is employed to impart a pressure increase to the oxygen.
    Type: Grant
    Filed: July 6, 1984
    Date of Patent: December 24, 1985
    Assignee: Union Carbide Corporation
    Inventors: Robert A. Beddome, Harry Cheung
  • Patent number: 4443238
    Abstract: Process for separating a hydrogen-containing refinery-type gas mixture into various fractions using reflux condensation, drying and partial condensation and phase separation.
    Type: Grant
    Filed: July 19, 1982
    Date of Patent: April 17, 1984
    Assignee: Union Carbide Corporation
