    Abstract: An apparatus for shaping a workpiece made of glass using minimum lubrication is provided. The apparatus includes device for heating the workpiece, a shaping station with at least one forming tool for shaping the workpiece, and at least one spray nozzle for applying an oil as a lubricant onto the surface of the forming tool. The forming tool exhibits heat dissipation such that the temperature on the contact surface of the forming tool during the shaping process is kept below 300° C. The amount of oil dispensed by the spray nozzle per forming step and application instance is less than 0.1 g.

  • Patent number: 7655879
    Abstract: A method for producing permanent integral connections of oxide-dispersed metallic materials by welding. The materials or components to be connected are overlapped to form an overlapping region in a joining region of the overlapping region. The materials or components are heated below the melting temperatures of the materials and are welded to at least partially form a diffusion bond by a welding method. A noble metal foil may be between the components to be connected. The diffusion bond is heated subsequently to a temperature below the melting temperature of the materials or components and the bond is mechanically recompacted by hammering.
