Abstract:
A solid skirt seal mounted to the bottom edge of a slide-glide door panel hinged to rotate about an axis generally parallel to the bottom edge of the door panel, a spring biasing the hinged skirt seal to rotate the lower edge of the skirt seal in a downward direction, and a flexible cover extending between the lower edge of the skirt seal and the lower edge of the door panel.
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.

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.
Abstract:
The invention relates to a drive control for an electric drive with a secure electrical separation of power element and control element. The aim of the invention is to reduce the number of components such as optic couplers and buffer amplifiers between the power element and a control electronics. To this end, a suitable electrical transformer (U) is inserted in a digital communication interface (K) between the control unit (R) and the control electronics (A) for the purpose of providing a secure electrical separation. To make use of a transformer (U) possible, a non-zero frequency encoding, for example a Manchester encoding, is carried out. Alternatively, an Ethernet physics can be used to provide a suitable communication interface. The transformer electrically insulates the two communication paths from each other that are provided in an Ethernet physics and preferably has little coupling capacity and a low attenuation factor.
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.
