Abstract: The mechanical timepiece movement includes an escapement having a pallet-lever arranged to move alternately into abutment with two banking elements in locking periods. The pallet-lever carries at least a first permanent magnet and the timepiece movement further includes a first element and a second element of high magnetic permeability and a second magnet and a third magnet respectively integral with first and second elements of high magnetic permeability and each arranged on an opposite side to a first magnet relative to the respective elements of high magnetic permeability. This magnetic system generates, in a first part of a first half vibration of any vibration of the pallet-lever, an overall force of magnetic attraction, defining a magnetic draw additional to the mechanical draw generated by the escape wheel, and, in a second part of this first half vibration, an overall force of magnetic repulsion.

Abstract: The timepiece mechanism comprises a rotating wheel set, a support element, a pivoting member mounted on the support element and magnetic return means for returning one portion of the pivoting member against a surface of the rotating wheel set. The return means comprise a first magnet carried by the pivoting member and a second magnet carried by the support element. The first and second magnets are arranged such that, in normal operation, the interaction of their respective magnetic fields generates a magnetic force oriented to return said pivoting member portion towards said rotating wheel surface. At least one of the first and second magnets is arranged to permit reversal of its polarity, preferably with the aid of a tool, and thereby of the direction of the magnetic force acting on the pivoting member, said magnetic force then tending to move said pivoting member portion away from said rotating wheel set surface, which makes it easy to handle the various elements of the timepiece mechanism.

Abstract: In this elevator system, a traveling body has arranged upon it a safety gear for braking and holding the traveling body tight on the guiderail, or on a braking rail. The safety gear is connected to a device for actuating the safety gear, which can also actuate the safety gear. The device for actuating the safety gear contains a coupler body, which can be pressed against the elevator hoistway, possibly against the guiderail or braking rail, wherein actuation of the safety gear is effected by a relative movement between the pressed-on coupler body and the safety gear. For this purpose, the coupler body can contain a curved coupler surface, which, in case of need, is brought into engagement with the elevator hoistway, or with the guiderail or braking rail.
