Abstract: A method for modifying the mechanical and surface properties of a component. The method involves: removably attaching a component to at least one component support that is located within a vibratory trough of a component treatment apparatus, the at least one component support being a support shaft upon which the component is removably mountable within the vibratory trough; supplying the vibratory trough with treatment media; moving the component support or the vibratory trough so that the component is immersed into the treatment media; vibrating the vibratory trough to provide a substantially uniform surface treatment of the component, the vibratory trough being movable by at least one trough vibrating mechanism whose actuation is controlled by a controller in response to signals received from at least one sensor located on or within the vibratory trough; removing the component from the treatment media; and detaching the component from the component support.

Abstract: A door module for a motor vehicle door having a module carrier which is formed substantially by organic sheet, a longitudinally extending channel which is formed integrally in the organic sheet of the module carrier, an insertion opening which extends along the direction of extent of the channel and via which a reinforcement element of the motor vehicle door is insertable into the channel, and at least one functional element which is fixed to the module carrier and which crosses the channel and thereby partially covers the longitudinally extending insertion opening thereof. In the organic sheet of the module carrier, there is formed an elastically deformable bending region which enables the channel to be bent open at least in sections, and/or enables the channel to be bent away from the functional element, in order to open up the insertion opening of the channel for the insertion of the reinforcement element.

Abstract: With a method for surface strengthening and smoothening of metallic components, in particular of rotors or rotor drums (7) with integral blading for aircraft engines, the components are loaded in a vessel (2) which is filled with strengthening elements (10). A tumbling movement is performed by which the metallic components are strengthened and smoothened by a relative movement between the workpiece surface and the strengthening elements in one process step. The strengthening elements (10) have a circumferential, rounded edge area, or compressive strengthening area (13) for strengthening the surface, and, extending therefrom on both sides, a flatly curved smoothening area (14) for smoothening the surface roughened by strengthening. With low time and apparatus investment, workpieces can be provided that feature high fatigue strength and advantageous aerodynamic properties.

Abstract: A motor vehicle door with a door body includes a door outer shell and a door inner shell between which a window lifter for lifting and lowering a window pane is configured within a door shaft. A component disposed inside the door shaft presents a crosslink between the window pane or the window lifter and at least one door shell. As an antitheft protection the component rests against the window pane or the window lifter under prestress and is swiveled, when the window pane is lifted, from the door shaft into a positive lock position with the door shell by a catch or support disposed on the window pane. In order to improve lateral and front-crash protection, the component is linked with the window pane and establishes a positive or negative lock between the door shells in a defined position of the window pane.
