Patents by Inventor Jonathan Sidney Edelson

Jonathan Sidney Edelson 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).

  • Low work function electrode
    Patent number: 5874039
    Abstract: A substrate is coated with a compound comprised of a cation completed by a heterocyclic multidentate ligand, which provides a surface having a low work-function and facilitates the emission of electrons.
    Type: Grant
    Filed: September 22, 1997
    Date of Patent: February 23, 1999
    Assignee: Borealis Technical Limited
    Inventor: Jonathan Sidney Edelson
  • Low work-function electrode
    Patent number: 5810980
    Abstract: A metal surface is coated with a heterocyclic multidentate ligand compound, reducing work function and facilitating the emission of electrons.
    Type: Grant
    Filed: November 6, 1996
    Date of Patent: September 22, 1998
    Assignee: Borealis Technical Limited
    Inventor: Jonathan Sidney Edelson
  • Method and apparatus for vacuum diode-based devices with electride-coated electrodes
    Patent number: 5675972
    Abstract: Vacuum diode-based devices, including Vacuum Diode Heat Pumps and Vacuum Thermionic Generators, are described in which the electrodes are coated with an electride. These materials have low work functions, which means that contact potential difference between cathode and anode may be set against the effects of space charge, resulting in an improved device whereby anode and cathode may be set at a greater distance from each other than has been previously envisaged.
