Abstract: A quick-action door includes a flexible door leaf (12; 14) and a rotatable shaft configuration including at least one rotatable shaft (8), which is configured for the winding-on of the door leaf (12; 14). The door leaf (12; 14) is made from a felt material (32; 36). The felt material (32; 36) is provided with a vapor diffusion-proof coating (34) on at least one surface.

Abstract: A quick-action roll-up door (1) for a cold storage room has a flexible door panel (5), which is windable onto a horizontal shaft (4) in a vertical running direction for purposes of closing a door opening (2) bounded by a door frame (3). A winding drive (6) opens and closes the door, together with a pressure application frame (8), subjecting the door panel in a closing position to force, transverse to a planar face of the door panel, in the direction of the door frame. Furthermore, device features are provided, which apply force to the pressure application frame in the direction of the door frame when the roll-up door is closed, and relieve it when it is opened. The device features have a traction drive (14), which is functionally connected to the winding drive for the door panel, and which controls the movement of the pressure application frame.

Abstract: A quick-action roll-up door includes a flexible door leaf (6) with a vertical running direction for closing a door opening bordered by a door frame (1). The quick-action roll-up door includes a drive (7) for the opening and closing of the door and a pressing fixture, with which the door leaf in a door leaf closed position can be pressed against the door frame (1).

Abstract: A door includes a door leaf (1) with a vertical running direction and a drive (7) for opening and closing the door. A braking device (8) is provided, and this is configured such that the door leaf (1) cannot be moved in the closure direction solely by a weight force thereof, but only with the assistance of the drive (7).

Abstract: A method for verifying the plausibility of a measuring device for determining a quality of an aqueous urea solution in a reservoir of an SCR catalyst system comprises determining whether a filling of the reservoir has taken place, determining the quality of the aqueous urea solution in the reservoir and detecting whether an error of the measuring device is present or whether the reservoir was filled with an aqueous urea solution, the quality of which deviates from a default value consisting of a filling status of the reservoir and the quality of the aqueous urea solution in said reservoir.

Abstract: A lock, which is designed as a panic lock for a door of freezing room, includes a chassis (1, 2) and a latch bolt (3), which is displaceably guided into the chassis, impinged upon by a spring force in the direction of extension and beveled at least on one side. A two-part nut is rotationally mounted inside the lock. The inside part is able to be actuated by an inner operating lever, including an inner catch which enables the latch bolt (3) to be actuated at least in the insertion direction. An outer nut part (7), which can be actuated by an outer operating lever, includes an outer catch (10) enabling the latch bolt (3) to be actuated in the insertion and extraction direction. When the operating lever is not actuated, structure (15, 16) places the catch (10) of the nut part (7) in a neutral position in which the catch (10) is not in contact with the latch bolt (3). Structure (21-24) are also provided for locking the outer catch (10) in the neutral position thereof.

Abstract: A method for checking the plausibility of the signals of a tank filling level sensor of a motor vehicle (120) is characterized in that the roadway inclination of the roadway (130) which is traveled on by the motor vehicle (120) is determined, and definitive information about the possibility of using the signals of the tank filling level sensor is obtained as a function of the roadway inclination (N).
