Patents by Inventor Alexander Pines

Alexander Pines 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).

  • Probe for high resolution NMR with sample reorientation
    Patent number: 4899111
    Abstract: An improved NMR probe and method are described which substantially improve the resolution of NMR measurements made on powdered or amorphous or otherwise orientationally disordered samples. The apparatus mechanically varies the orientation of the sample such that the time average of two or more sets of spherical harmonic functions are zero.
    Type: Grant
    Filed: August 3, 1988
    Date of Patent: February 6, 1990
    Assignee: The Regents of the University of California
    Inventors: Alexander Pines, Ago Samoson
  • Method and apparatus for measuring nuclear magnetic properties
    Patent number: 4710714
    Abstract: A method for studying the chemical and structural characteristics of materials is disclosed. The method includes placement of a sample material in a high strength polarizing magnetic field to order the sample nucleii. The condition used to order the sample is then removed abruptly and the ordering of the sample allowed to evolve for a time interval. At the end of the time interval, the ordering of the sample is measured by conventional nuclear magnetic resonance techniques.
