  • Patent number: 8881524
    Abstract: The invention relates to a device for opening a passenger door (1) of an aircraft in case of emergency, which is fastened so it is manually pivotable on the fuselage (3) of the aircraft via a hinge and/or support arm configuration (2), an auxiliary-energy-operated emergency opening drive (4) being provided between the fuselage (3) and the passenger door (1), which automatically opens the passenger door (1) in accordance with an emergency control unit (5), the auxiliary energy for the emergency opening drive (4) being pyrotechnic energy, whose gas expanding inside an expansion chamber (6) after triggering by the emergency control unit (5) impinges the emergency opening drive (4) with pressure medium to open the passenger door (1), wherein said emergency opening drive (4) generates a rotational movement.

  • Patent number: 7543394
    Abstract: An exchanging device is for exchangeably holding a sensor, probe element or tool on a machine or on a machine part or a rotation-pivot unit on a machine or a machine part, preferably, a coordinate measuring apparatus. The exchanging device includes a take-up holder having a first bearing part and a counter piece (22) having a second bearing part corresponding to the first bearing part. A releasable clamping unit (42), for example, a magnetic clamping unit, is provided with which a clamping force is generated between the first and second bearing parts when the counter piece is accommodated on the take-up holder. A locking device having a first locking element (29) is provided on the take-up holder and a counter piece corresponding to the locking element (29) of the take-up holder is provided on the counter piece (22), for example, in the form of a slider (30). With the locking device, the counter piece can be mechanically coupled to the take-up holder in the state when it is taken up by the take-up holder.
