  • Patent number: 8839558
    Abstract: A sealing assembly for sealing a gap between a swing door and a floor comprises a sealing member installed to be able to rotate from a closed position to an open position, an elastically deforming member made of an elastomer composition engaged to the sealing member, and a seal driving member to rotate the sealing member from the closed position to the open position when the door is opened. The elastically deforming member is deformed when the sealing member rotates from the closed position to the open position, and the sealing member returns from the open position to the closed position by elastic force of the elastically deforming member when the door is closed.

  • Patent number: 8291644
    Abstract: A locking mechanism (100) for use with a pneumatic cylinder/differential engine for a power-operated door including a locking rod (20), a plunger (24) associated with the locking rod (20) to cause extension and retraction of the locking rod (20) with respect to a door opening/closing gear (46), and a spring member (34) associated with the plunger (24) for maintaining the plunger (24) and the locking rod (20) in an extended position during a door closed position. An aperture (46a) is located through a sidewall portion of the gear hub (46b) which is capable of receiving an end (20a) of the locking rod (20) when the locking rod is in an extended position to lock the door in a door closed position. The invention also includes an emergency door opening mechanism enabling manual opening of the doors in case of an emergency.

  • Patent number: 7603977
    Abstract: The invention relates to a cooling duct piston for an internal combustion engine comprising heat pipes. In order to improve dissipation of heat from the thermally loaded piston areas while preventing thermal tensions, liquid-filled heat pipes that are provided with an evaporator end and a condenser end are disposed in bores of the cooling duct which are oriented towards the bottom of the piston. The heat pipes are arranged such that the evaporator ends terminate at the end of the bores which faces the piston bottom while the condenser ends terminate in the closed cooling duct.

  • Patent number: 7549368
    Abstract: The invention relates to a lightweight piston comprising heat pipes. The aim of the invention is to simplify the structure of such a piston while at the same time allowing for an improved heat dissipation from the piston areas subject to heat load while avoiding thermal stress. For this purpose, a plurality of liquid-filled heat pipes each having an evaporator and a condenser end is used, whereby the evaporator end is configured by short pipe sections that are oriented in the thickness at bottom towards the focal point and that are interlinked by means of a composite heat pipe extending in parallel to the piston head. At least two pipe sections functioning as the condenser end are coupled with the composite heat pipe in such a manner as to configure, by way of a pipe connection arranged on the condenser ends, a closed coolant cycle between the evaporator end, composite heat pipe and condenser end of the heat pipe.
