  • Process for the electrochemical regeneration of pyridine cofactors
    Patent number: 5538867
    Abstract: The present invention relates to a process for the electrochemical regeneration of pyridine cofactors.The process of the invention is characterized by the use, in a reaction medium subjected to electrolysis, of a cytoplasmic hydrogenase enzyme.
    Type: Grant
    Filed: June 13, 1994
    Date of Patent: July 23, 1996
    Assignee: ELF Aquitaine
    Inventors: Helene Durliat, Maurice Comtat, Jean-Luis Seris
  • Method of using a thermal shock probe, a thermal shock probe usable in the method and application of this method
    Patent number: 4994394
    Abstract: The present invention provides a method of using a thermal shock probe, such a thermal shock probe and application of this method to the control of a heat pump. The method of using a thermal shock probe formed of a thermocouple associated with a heating element, is characterized in that it is used for monitoring, in a solid-gas reactor (1,2), the chemical reaction between a porous mixture and a gas by applying a heat flux variation and processing the response of the thermocouple.
