Klaus Eberle 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).

  • Flat product, such as sheet, made of steel having a high yield strength and exhibiting good ductility and process for manufacturing this product
    Patent number: 6395108
    Abstract: A flat product made of multiphase steel and a method for preparing the steel includes hot rolling at a temperature at which the austenite phase is stable, then tempering to form a C and Mn-enriched phase in a matrix, followed by a heat treatment to form austenite islands and/or enriching in Mn the already formed austenite and cooling down to room temperature so as to obtain a final product with a ferrite matrix containing residual austenite, bainite and/or martensite islands.
    Type: Grant
    Filed: April 30, 2001
    Date of Patent: May 28, 2002
    Assignee: Recherche et Developpement du Groupe Cockerill Sambre
    Inventors: Klaus Eberle, Philippe Harlet, Pierre Cantinieaux
  • Device and method for combined purification and compression of hydrogen containing CO and the use thereof in fuel cell assemblies
    Patent number: 6361896
    Abstract: The invention relates to a device for combined purification and compression of hydrogen containing CO. Said device comprises a polymer electrolyte membrane (PEM) cell with a proton-conducting polymer membrane (3), an anode on one side of the membrane and a cathode (4) on the other side thereof. Said anode is in the form of a two-layer anode (5) which comprises a CO-oxidation-selective catalytic layer (1) on the side facing away from the membrane and an electrochemically active layer (2) for oxidation of the hydrogen to form protons on the side facing the membrane. The PEM cell also has a flat, porous gas distribution layer provided on the anode side and attached to a current collector. Consequently, the PEM cell resists differential pressures of at least approximately 10 bar. The invention also relates to a process for combined purification and compression of hydrogen containing CO using said device.
