Abstract: A transfer apparatus includes a primary part, and at least one first and one second secondary part, which are each magnetically coupled to the primary part for drive purposes. A regulation device is provided for regulation of a drive of the secondary parts. The regulation device can regulate the drive of the first secondary part in a first zone of the primary part in accordance with a first regulation rule, and can regulate the drive of the second secondary part in a second zone of the primary part in accordance with a second regulation rule. The first and second regulation rules differ hereby from one another. The first zone is separated from the second zone by a boundary which can be varied dynamically by the regulation device.

Abstract: A method is disclosed for producing a pole face of a metal closing elements of a solenoid, especially for electromechanical switchgear. In at least one embodiment, the method includes machining the surface of a crude stamped part of the closing element to give the pole face. A corresponding armature, yoke, solenoid and switchgear are also disclosed.

Abstract: A method for producing a solenoid with a center limb and two outer pole shanks that have one pole surface each and one back resting so that it faces away from it. The back is first at least partially freely formed. The solenoid is then elastically tensioned towards the back by a tensioning device. In the tensioned state, the pole surfaces are ground so that the solenoid, when withdrawn from the tensioning device, has a convex support surface constituted by the pole surfaces.
