A device for locking a leaf of a door or the like comprising at least one electric motor operated as a generator having a motor shaft which is operatively connected to the leaf via a force transmission unit. The motor terminals of at least one electric motor operated as a generator are connected in this regard to a damping circuit for damping the leaf movements. The motor shaft of at least one electric motor operated as a generator is acted on by a brake unit to lock the leaf.

An oven appliance includes a cabinet that defines a chamber. A pair of doors is rotatably mounted to provide selective access to the chamber of the cabinet. The pair of doors is connected with a linkage assembly such that the doors rotate open and closed simultaneously. The linkage assembly includes a spur gear that engages another gear of the linkage assembly. The spur gear can hinder unwanted rotation of the pair of doors or compress the pair of doors against a seal.

An agricultural harvester includes a chassis and a grain tank carried by the chassis. The grain tank includes a frame having an opening formed therethrough; a pair of tank cover sections movably associated with the frame such that the tank cover sections can switch between an open position and a covering position relative to the opening of the frame; and at least one actuator linked to at least one of the tank cover sections and configured to selectively provide a switching force. The agricultural harvester further includes a force assistor or a brake linked to one of the pair of tank cover sections and configured to apply an assist force or a braking force, respectively, to one of the pair of tank cover sections but not the other of the pair of tank cover sections.
