  • Octamethylcyclotetrasiloxane interacts with lithium ions
    Patent number: 11279626
    Abstract: Provided is a method of extracting a metal ion, which comprises contacting a compound of formula (R2SiO)n with a source of the metal ion, whereby the compound and the metal ion form a complex, wherein each R is independently C1-10alkyl, and n is 3-10.
    Type: Grant
    Filed: June 11, 2019
    Date of Patent: March 22, 2022
    Assignee: Board of Trustees of the California State University
    Inventors: Robert E. Pellenbarg, Kimberley R. Cousins

  • Desalination through gas hydrate
    Patent number: 6158239
    Abstract: In one embodiment, this invention pertains to desalination of seawater by eding methane into seawater at a depth generally exceeding 100 meters to form methane hydrate which rises to where it is decomposed into methane and water, and recoverig water. Methane is recycled to depth to form more buoyant hydrate.
    Type: Grant
    Filed: November 18, 1998
    Date of Patent: December 12, 2000
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Michael D. Max, Robert E. Pellenbarg
  • Inflatable, noncollapsible, personal flotation device
    Patent number: 6066017
    Abstract: The inflatable, non-collapsible, flotation device (INCFD) utilizes foam mng chemicals within a flotation chamber where the materials react and harden to form a layer of pliant foam, such as polyurethane. The foam, during reaction, conforms with the shape of the wearer and hardens to provide both flotation and physical protection from exterior objects.
    Type: Grant
    Filed: January 29, 1998
    Date of Patent: May 23, 2000
    Assignee: The United States of America as represented by the Secretary of the Navy

    Inventors: Michael D. Max, Robert E. Pellenbarg
  • Self moistening composition for deactivating toxic substances and method of use
    Patent number: 4902441
    Abstract: An self-moistening inactivating agent for toxic substances provided in a er-vapor-impervious container. The agent comprises an intimate admixture of at least one hygroscopic material and at least one oxidizing agent. The agent can also contain chelating materials and electrostatic materials. The agent is used to inactivate toxic substances on the ground or on contaminated surfaces. Particularly, the agent inactivates organo phosphorous toxic agents.
    Type: Grant
    Filed: March 31, 1988
    Date of Patent: February 20, 1990
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Robert E. Pellenbarg, Homer W. Carhart
  • Organic vapor assay by Raman spectroscopy
    Patent number: 4886358
    Abstract: A method of and apparatus for analyzing for low concentrations of organic material in the atmosphere without the removal of water wherein an air sample is collected and cooled to form a condensate consisting essentially of water and organic material. The condensate is analyzed by Raman spectroscopy to detect and quantify the organic material.
    Type: Grant
