Martin Von Allmen 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).

  • Method for producing an at least partly amorphous alloy piece
    Patent number: 4797166
    Abstract: An alloy, e.g. a Cr-Ti alloy, is transformed to a metastable crystal modification, e.g., by heating in an electric arc and quenching in water. The metastable crystal modification is annealed at a temperature which is below the glass temperature, e.g. at 600.degree. C. during 48 hours, causing it to vitrify completely.The inventive method provided the production of large pieces of hard and non-porous amorphous alloy with thicknesses in the centimeter range.
    Type: Grant

    Date of Patent: January 10, 1989
    Assignee: Cendres & Metaux, S.A.
    Inventors: Martin Von Allmen, Andreas Blatter
  • Method for ablating metal workpieces with laser radiation
    Patent number: 4114018
    Abstract: A technique for ablating a metal workpiece by the use of laser beam radiation at an efficiency higher than heretofore possible and an improved regulation of the ablation process. Undesired side effects of the ablation process are eliminated by the entire and complete ejection of the molten metal at the point of beam impingement so that no material remains on the workpiece in the areas between contiguous points of ablation. The appropriate selection of beam intensity and the selection of pulse shape provide the inventive technique.
