Abstract: In a method for treating objects, the objects are transported through a basin by a transporting device. Treatment solution is introduced into the basin by way of at least one feeding device, which is provided with upwardly directed outlet openings. The treatment solution is sprayed upwards by the upwardly directed outlet openings to form jets of treatment solution. The objects are transported through the basin over the upwardly directed outlet openings and a downwardly facing surface of the objects is brought into contact with the jets of treatment solution during the transport of the objects through the basin. There is also described a treatment apparatus for carrying out such a method.

Abstract: A method of producing a forming tool for producing a complex formed part with a target geometry by performing a drawing type of forming pro cess on a workpiece, wherein the forming tool has an active surface that engages the workpiece to be formed including determining an active-surface geometry specification for the active surface; and producing the active surface according to the active-surface geometry specification.

Abstract: A current-compensated choke features several current paths and includes several windings that are connected in parallel and wound around a common core. The windings preferably are alternately wound on the core in such a way that windings of a common current path are not arranged directly one on top of another.
