  • Separation of ammonium chloride from the gas phase of an isocyanate production process
    Patent number: 9029594
    Abstract: Isocyanates are produced in the gas phase and by-products such as ammonium halides are selectively separated from the gas phase by desublimation.
    Type: Grant
    Filed: May 26, 2009
    Date of Patent: May 12, 2015
    Assignee: Bayer MaterialScience AG
    Inventors: Sven Michael Hansen, Ralf Schneider, Bernd Schwethelm, Rolf Schiefer, Jürgen Dreher
  • BRAKE LINING HAVING A BACK PLATE HAVING INCREASED STIFFNESS
    Publication number: 20130277160
    Abstract: A brake pad having increased stiffness comprises a back plate and a friction lining attached to one side of the back plate. Embedded in the lining bed of the back plate facing the friction lining is at least one connecting element having at least one undercut for fastening the friction lining to the back plate, and at least one rib for increasing the stiffness is additionally provided. This arrangement will ensure attachment of the friction lining to the back plate and increased stiffness of the back plate.
