Abstract: A clamping platform for a mechanical shaker, which allows automated release and fastening of microtiter plates that are subject to tolerances, includes at least two mounts arranged pairwise for the releasable fastening of the microtiter plates. The platform includes clamping jaws, on which a compression spring acts, actuatable with a link control having a linear drive. In conjunction with the compression spring, the geometry of the guide links allows compensation for the dimensional tolerances of the microtiter plates that are to be fixed by clamping. The spring force of the compression spring is determined such that the clamping jaws that are loaded by the compression spring exert the required clamping force in the deployed position onto the microtiter plates to be fixed.

Abstract: A door system for an elevator installation having an elevator car with a car door arranged to travel in an elevator shaft with shaft doors, wherein the car door is spaced from the shaft doors in a closed position of the door system. A primary pivot spindle is coupled to a pivotable door leaf of the shaft door or the car door and a secondary pivot spindle is coupled to a pivotable door leaf of the other of the car door and the shaft door. A drive unit includes a driven, pivotably mounted shaft to which a first entrainer and a second entrainer are fixed. During a pivoting movement of the shaft, the first entrainer engages a first counterpart element on the primary pivot spindle and the second entrainer engages a second counterpart element on the secondary pivot spindle to effect a pivoting movement of the door leaves.

Abstract: A door system for an elevator installation having an elevator car, the door system including a pivotable first car door leaf mounted at a car door opening and a pivotable first shaft door leaf mounted at a shaft door opening of the elevator installation. At least a part of the shaft door opening is closed by the first shaft door leaf in a closed position thereof and a shaft door plane is formed along the shaft door leaf. At least a part of the car door opening is closed by the first car door leaf in a closed position thereof and a car door plane is formed along the car door leaf. The car door leaf, in an open position thereof, extends through the shaft door plane, or the shaft door leaf, in an open position thereof, extends through the car door plane.
