Ralf Niemeier 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: 6772499
    Abstract: A method of producing metal sections wherein first a groove is made in a section limb by microstructure-changing deformation, then another section limb is placed in the groove and that material of the first section limb which is situated to the side of the groove is moved onto the side walls of the inserted section limb by pressure to such an extent that an at least force-fitting joint between the two section limbs is made at the contact location. This method of microstructure-changing attachment of section limbs makes it possible to produce metal sections with virtually any desired geometry and using any desired starting materials the strength of which sections is comparable to metal sections produced in a previously known manner.

  • Publication number: 20020116809
    Abstract: The invention relates to a method of producing novel metal sections. In the novel method, firstly a groove is made in a section limb by microstructure-changing deformation, then another section limb is placed in the groove and that material of the first section limb which is situated to the side of the groove is moved onto the side walls of the inserted section limb by means of pressure to such an extent that an at least force-fitting join between the two section limbs is made at the contact location. This method of microstructure-changing attachment of section limbs makes it possible to produce metal sections with virtually any desired geometry and using any desired starting materials in a cost-effective manner, the strengths of which section is comparable to metal sections produced in a previously known manner.
