  • Modularly structured flow conditioning unit
    Patent number: 8950436
    Abstract: A modularly structured unit is comprised of a flow resistance element and an orifice plate adjacent thereto, preferably for use in the main flow duct of a thermal mass flow rate measuring or control device. The flow resistance element can be combined with various orifice plates having different opening diameters.
    Type: Grant

  • Apparatus for providing conditioned fluid flows
    Patent number: 8485227
    Abstract: To provide conditioned fluid flows, a base body has a main flow duct formed therein with a bypass duct that is branched off from and led back to the main flow duct. An exchangeable flow conditioning insert includes a flow resistance element and is adapted to be arranged in the main flow duct relative to the bypass duct in an axial installation position such that the flow resistance element generates a pressure difference between ports of the bypass duct at the main flow duct.

  • Segmented safety aircraft
    Patent number: 5356097
    Abstract: An aircraft includes a cockpit permanently connected to a fuselage base. At least one fuselage segment is detachably mounted to the support. In case of an imminent crash the segment is detachable from the remainder of the aircraft and can float to safety after being detached by having at least one parachute and an airbag secured to the segment.
