Hartmut BAUMGART 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: 10344349
    Abstract: A method for treating sheet metal is disclosed. An amorphous mass containing an alloying element is applied onto a first area of a surface of the metal sheet. A second area of the surface is kept free of the amorphous mass. The amorphous mass and at least the first area of the metal sheet are heated in order to alloy the alloying element into the first area of the metal sheet while the second area remains unalloyed.
    Type: Grant

  • Patent number: 10309004
    Abstract: A method for treating sheet metal is disclosed in which a material containing at least one alloying element is applied onto a first area of at least one surface of the metal sheet. A second area of the surface is kept free of the material. The metal sheet is subsequently heat treated in order to diffuse the alloying element into the first area of the metal sheet. The temperature of the first area is lower than the melting temperature of the metal sheet during the diffusion.

  • Patent number: 10297384
    Abstract: A workpiece made of plate is subjected to a treatment which locally modifies its magnetic permeability. Subsequently, the magnetic permeability of the workpiece is examined locally resolved by a probe in order to find at least one surface region which is suitable for intended processing, and the processing is performed locally limited to the selected region.

  • Patent number: 10137942
    Abstract: A workpiece includes a plurality of knots and webs, which are formed in one piece, of a sheet metal, in particular a steel plate. Each web extends between two openings from one knot to another knot, and at least three webs meet at each knot. A plurality of the webs has a cross section, which includes at least one hardened and one unhardened area.

  • Patent number: 9873935
    Abstract: A method for locally treating a plate is disclosed. A pattern formed from a compound containing at least one alloying element is applied onto at least one surface of the plate. At least the surface of a contacting layer including the pattern is covered by adequately heat-resistant material. The plate is subsequently heat treated in order to diffuse the alloying element into the plate.
