  • Method for producing permanent integral connections of oxide-dispersed (ODS) metallic materials or components of oxide-dispersed (ODS) metallic materials by welding
    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.
    Type: Grant

  • Apparatus for setting and/or monitoring the operation of a shell fuse or detonator
    Patent number: 4495851
    Abstract: Apparatus for setting and/or monitoring the operation of an electronic fuse for shells to be fired from a gun, by transmitting a microwave data signal and a microwave energy signal to a device inside the fuse from a device outside the fuse, the device inside the fuse including an energy receiver with a rectifier for generating a supply voltage, a data receiver, a data processing unit and a fuse electronic system, and the device outside the fuse including an energy transmitter, an input/output unit and a data transmitter, including means for disposing the device outside the fuse so that the transmission of the microwave signals occurs at the latest during loading of the shell carrying the fuse into the gun; means for transmitting the energy signal and the data signal together and simultaneously; a reply signal transmitter additionally included in the device inside the fuse; a reply signal receiver additionally included in the device outside the fuse; the data-signal transmitting means and the reply signal tran
