Abstract: The present invention relates to a method for mounting electrical components on leadframes. A conveyor belt is used, having a holder which is attached to the conveyor belt. A leadframe is placed on the conveyor belt and is adjusted and held in position relative to the holder. The leadframe thus maintains its position relative to the endless conveyor belt throughout the entire period for which it remains on the endless conveyor belt.

Abstract: The present invention comprises a process system and a process method for mounting electrical components on leadframes. An endless conveyor belt is used for this purpose, having a holder which is attached to the conveyor belt. A leadframe is placed on the conveyor belt and is adjusted and locked relative to the holder. The leadframe thus maintains its position relative to the endless conveyor belt throughout the entire period for which it remains on the endless conveyor belt.

Abstract: A test procedure or test station for testing products, especially products completed on an assembly line type production process, performing the following steps: First, testing a parameter of a product with a first testing device using a first input signal to produce a first test result. Second, testing the same parameter of the product with a second testing device using a second input signal that is independent of the first input signal to produce a second test result. Third, deriving a differential value from the test results obtained by the testing devices. Fourth, determining the conformance of the testing station from the differential value and outputting an error message when the differential value deviates from a predetermined range. Fifth, repeating above steps for at least one other parameter.

Abstract: A mounting for the draw rod of the coupling body of a trailer coupling is proposed. The draw rod passes through a cross-piece bore of a cross-piece fast with the towing vehicle. The cross-section of the draw rod at the passage through the cross-piece bore corresponds to the cross-section of the cross-piece bore. A bearing tube secured to the cross-piece for the guidance of the draw rod extends from the cross-piece only in the direction pointing away from the coupling body. Between the end of the draw rod remote from the cross-piece and the end of the bearing tube remote from the cross-piece a support acting in both force directions is provided, that is to say a support for traction force transmission and a support for thrust force transmission. In the solution according to the invention the cross-section of the draw rod can be enlarged compared with conventional forms of embodiment.

Abstract: In a trailer coupling having two independently effective securing arrangements, of which the one is formed by an opener lever and the other by a securing bolt, the opener lever engages in an upwardly partially open slot of the coupling bolt and is reinforced by a disengaging cam which emerges upwards from the slot and co-operates with the securing bolt in the direction of its disengagement.

Abstract: A trailer coupling is proposed which, after transference of the coupling bolt into the non-coupling position, is insensitive to small relative movements of the towing eye, still situated in the coupling body, in relation to the coupling body, that is to say does not drop back into the coupling position, and in which, on the other hand, the coupling bolt can be caused by the entry of the towing eye to return into the coupling position, without a repeated manual action upon the automatic coupling system being necessary.
