Patents by Inventor Laurent ZIMMERMANN

Laurent ZIMMERMANN 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).

  • High-temperature all-metal induction furnace, intended to melt samples of minerals and/or rocks for extracting gases under ultra-high vacuum
    Patent number: 11421936
    Abstract: The application basically comprises supplying a high-temperature ultra-high vacuum furnace, the sole chamber of which is metal, in which an electrically conductive crucible, preferably made of tantalum, is placed onto an insulating support, preferably a ceramic, and is induction heated by a winding wound around the crucible. The insulating tube, preferably made of quartz, that is arranged between the induction winding and the crucible, advantageously acts as a surface on which the condensable species can condense. The quartz insulating tube especially allows the induction winding to be protected.
