  • Process and device for supplying processing gas to a reactor located in a zone subjected to intense electric and/or electromagnetic fields
    Patent number: 5160825
    Abstract: The device described serves to supply processing gas to an ionic implanter isolated from its environment by an electrically conductive enclosure connected to earth.

  • Manual control device for a thermal relay
    Patent number: 5153551
    Abstract: A device for manually controlling a thermal relay associated with a contactor and housed, together with the contactor, in a case having stop and reset push-buttons, comprises levers mounted for rotation in a support fixed to the front of the box of the thermal relay.
