Patents by Inventor Nadine Vidal

Nadine Vidal 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).

  • Patent number: 9275780
    Abstract: A method for manufacturing a coil for generating an intense magnetic field when an electric current passes through it. Turns are formed in a cylindrical tube made of conducting or superconducting material. At least one indentation is formed in an edge of at least one turn. Insulating material is positioned between the turn including the indentation and an adjacent turn. The recess forms with the insulating material a channel between the interior and the exterior of the tube when the coil is stressed.
    Type: Grant

  • Publication number: 20130038331
    Abstract: The invention relates to a method for manufacturing a coil for generating an intense magnetic field when an electric current passes through it, comprising the formation of turns in a cylindrical tube made of conducting or superconducting material, the formation of at least one indentation in an edge of at least one turn of said coil and the positioning of insulating material between the turn comprising the indentation and an adjacent turn, said recess being made in the edge to form with the insulating material a channel between the interior and the exterior of the tube when the coil is stressed.

  • Patent number: 8307536
    Abstract: A method for manufacturing a coil capable of generating a magnetic field known as an intense field when an electric current passes through it. There is formed at least one boss on at least one turn of the coil and at least one recess of a corresponding form in an adjacent turn, such that the boss extends perpendicularly to the recess for absorbing the mechanical stresses caused by the electromagnetic forces and mechanical forces of thermal origin. The coil is capable of generating a magnetic field known as an intense field when an electric current passes through it. The coil includes a tube made of a conductive material and cut out along an overall helicoidal cut-out line. At least one turn of the coil includes at least one boss extending perpendicularly to a recess of a corresponding form in an adjacent turn.

  • Publication number: 20100271165
    Abstract: Coil capable of generating a magnetic field and method for manufacturing said coil. The present invention relates to a method for manufacturing a coil capable of generating a magnetic field known as an intense field when an electric current passes through it, comprising a formation step of turns in a cylindrical tube, wherein it comprises at least one formation step of at least one boss on at least one turn of said coil and at least one recess of a corresponding form in an adjacent turn, such that the boss extends perpendicularly to said recess, for absorbing the mechanical stresses caused by the electromagnetic forces and mechanical forces of thermal origin.
