  • Method for purifying exhaust gas and for regenerating an oxidation catalyst
    Patent number: 9815023
    Abstract: The invention relates to a method for purifying exhaust gas and for regenerating an oxidation catalytic converter, comprising treating the exhaust gas in an oxidation catalytic converter, which comprises a catalytically active material, which contains at least one noble metal and/or at least one base transition metal, wherein the oxidation catalytic converter is operated continuously or at times at a temperature that causes the oxidation of soot particles and/or carbon particles, and/or wherein the oxidation catalytic converter is periodically heated to a temperature that causes the oxidation of soot particles and/or carbon particles.

  • Structuring process that stiffens and protects the surface of thin material webs
    Patent number: 6221299
    Abstract: The present invention provides a profiling process which allows for the material sheet to be profiled so that the surface is minimally affected and only slight plastic deformation of the material occurs, and yet uniform three-dimensional structuring takes place. Additionally, the present invention allows for an improved inherent stability in the plane of the profiled material sheet to be achieved while only minimally affecting the cross-section.

  • Process and apparatus for vault-structuring of thin material sheets
    Patent number: 6217811
    Abstract: According to the invention thin sheets of foil are stiffened in a particular way by means of vault-structuring. The vault-structuring occurs either by self-organizing or following a self-organized design with a spade-shaped or drop-shaped pattern.
