Abstract: The invention relates to a method of actuating a door, in particular of a motor vehicle, wherein an electric drive motor coupled to the door is controlled by a motor control on a manual actuation of the door such that the drive motor exerts a force onto the door by which a system-inherent force countering the manual actuation is at least partly compensated. The invention also relates to an apparatus for the carrying out of a method of this type.

Abstract: A filter having two zones, the first zone having a low electrical conductivity and the second zone having a high electrical conductivity at electrode attachment zones due to infiltration of metal within the second zone.

Abstract: An improved four-bar hinge assembly for attaching a trunk deck lid to a vehicle body in which the control link of the four-bar linkage has its usual vehicle-mounted pivot pin replaced by the rotatably driven output drive shaft of a power drive mechanism that is rigidly and directly coupled to the control link to swing to the same and thereby power actuate the four-bar linkage in order to pivot the deck lid between open and closed positions. The hinge elements are located on the weather side of the vehicle body components and the drive shaft extends through the vehicle sheet metal into the weather sealed trunk compartment so that the electro-mechanical drive components are mounted within the weather sealed trunk.

Abstract: A filter system includes a longitudinally extending housing having a housing inlet and a housing outlet. A plurality of longitudinally extending, cross-sectionally rectangular cassette cases are exchangeably mounted within the housing. Each cassette case has an inlet associated with the housing inlet for receiving a medium to be filtered, and an outlet associated with said housing outlet for supplying filtered medium thereto. A plurality of longitudinally extending, cross-sectionally rectangular apertured filter elements formed of a ceramic filter medium are affixed within each cassette case. Each filter element of each cassette case extends along and is disposed adjacent at least one filter element of the associated cassette case. Each filter element has an inlet for receiving medium to be filtered and an outlet from which filtered medium flows.
