  • Hydraulically controlled pressure relief valve for high-pressure reactors
    Patent number: 7192561
    Abstract: A high-pressure reactor which has a hydraulically controlled pressure-relief valve. The mechanical design of the corresponding hydraulic system in combination with the control technology used facilitates particularly fast opening of the pressure-relief valve in the case of pressure or temperature jumps in the high-pressure reactor.
    Type: Grant
    Filed: June 20, 2001
    Date of Patent: March 20, 2007
    Assignee: Basell Polyolefine GmbH
    Inventors: Georg Groos, Klaus Hammer
  • Electronic component and utilization of a guard structure contained therein
    Patent number: 6714392
    Abstract: An electronic component is described and has a dielectric layer which is constructed on a substrate, conductive surfaces that are constructed on the dielectric layer, and an electrically conductive guard structure. The guard structure is disposed in a plane above the conductive surfaces such that the conductive surfaces are not completely covered by the guard structure.
    Type: Grant

  • Process optimization of peroxide injection during polyethylene production
    Patent number: 6384153
    Abstract: In a process for the high-pressure polymerization of ethylene in a high-pressure autoclave or in a high-pressure tube reactor having one or more metering points for one or more peroxides, no peroxide or a reduced amount of peroxide is metered in during the time interval in which the pressure is lowered by opening a pressure maintenance valve and the original amount of peroxide per unit time is metered in again as soon as the pressure after closure of the pressure maintenance valve has built up again so that it exceeds 90% of the pressure difference between nominal pressure and lowered pressure.
