Abstract: The invention relates to a component that is suitable for use as a sliding bearing. The invention further relates to a method for the production of said component. The design of the component according to the invention provides a layer of a light metal material (13), which is provided with an oxide layer (15) containing pores (16) in the direction of the sliding surface (23) of the component. A hard material (18) is placed in the pores, which greatly increases the firmness of said layer region, thus creating the mechanical firmness for use as a sliding bearing.

Abstract: An auxiliary device and a method for finishing and calibrating preforms that are removed from a multiple tool in an unstable shape, the calibration process being performed with compressed air immediately after removing and withdrawing the preforms from the multiple tool. Nipples that can be inserted into the preforms are provided with expandable press rings or sealing rings in order to seal the interior of the blow-molded part of the preforms. The compressed air is introduced via the nipples, the sealing process being performed by radially expanding the press rings or sealing rings in analogy to the closing process of thermoses, thus protecting the preforms from adverse forces. The sealing point can be randomly selected in the transition zone from the threaded part to the blow-molded part of the preforms. The interior of the blow-molded part is optimally sealed without affecting the form stability and dimensional stability of the preforms.

Abstract: An electrical machine includes a stator coupled to a machine frame and constructed to produce a magnetic field. A rotor which is connected to a shaft magnetically interacts with the stator and is separated there from by an air gap which is arranged such that the magnetic field within the air gap is directed essentially parallel to the shaft axis during operation of the electrical machine. Arranged between the rotor and the stator is an axial bearing which absorbs attraction forces acting between the stator and the rotor in a direction of the shaft axis. An elastic coupling mechanically couples the stator to the machine frame and is made less stiff than the axial bearing with respect to a force acting in the direction of the shaft axis, and constructed such that a force acting on the rotor in the direction of the shaft axis is able to cause the stator to be translated with respect to the machine frame in the direction of the shaft axis.
