Abstract: In the case of a device for ascertaining a fill level of a medium inside a collection container, having at least one measuring chamber, in which an ultrasonic sensor is arranged, connected to conduct media to the collection chamber, and having at least one antechamber connected upstream from the measuring chamber, which has at least one inlet opening for the medium from the collection chamber, at least one flow damper for the medium, according to the invention, is arranged in at least one subarea of the antechamber. Thereby multiple antechambers, which are connected in series one behind another to conduct media, are connected upstream from the measuring chamber.

Abstract: A mobile locking element and a method for unlocking a mobile element via the mobile locking element interacting with the mobile element, the method comprising the following steps:

Abstract: Given is a formed partition made of displaceable wall elements that are suspended, by means of carrier studs, on two carrier members that are displaceable in guide rails, and movable along their perpendicular interfaces in sealing contact against one another and/or against terminal elements. Situated on the horizontal interfaces of the wall elements are sealing strips that are capable of being extended in contact against the floor and/or the guide rails or the ceiling of the room. On one of the wall elements, one of the carrier studs is journaled in horizontally-displaceable fashion toward the other carrier stud. In order to be able to execute a simple and rapid transport of the wall elements, even diagonally, running in the guide rail is a drivable endless element to which are fixed, at a predetermined interval apart, two followers.
