Abstract: A holding device comprising a soft iron element and a magnet, which are arranged concentrically to one another, wherein the magnet, in operative connection with the soft iron element, exerts a holding torque on a shaft in a static state, wherein the magnet is arranged on the shaft, on the inner circumference of the soft iron element (UE), and forms a second rotating component (K2), and the holding device is in connection with one of the end shield of an electric drive and wherein the soft iron element is arranged on the shaft, on the inner circumference (UM) of the magnet, and forms a first rotating component (K1), and wherein the holding device is in connection with one of the end shield of an electric drive.

Abstract: A lab stirrer comprises a housing, a stirring shaft rotatably supported about an axis in the housing and a drive to drive the stirring shaft to make a rotary movement about the axis. A blocking device is provided to block the stirring shaft against a rotation about the shaft axis.

Abstract: A device (1) maintains a locked and closed state of a space separating device (2) in a releasable manner, in particular a protective device of a machine (4). The device has a first part (6) with an opening and a second part (8). The parts are movable relative to one another. The opening is at least partially closable. The device (1) includes a latch (18) for locking the closed state of the space-separating device (2), a holding element (30) for keeping the latch (18) in the latched position, and a release element (36) for releasing the catch of the latch (18). The catch of the latch (18) may be lifted by a rotational movement of the release element (36) relative to the latch (18).
