Abstract: A rectifier module for an active bridge rectifier having two switching elements, connected in series between two end terminals, and between which a center tap is formed, and a control circuit including a monitoring unit, a synchronization unit, and a control unit, the monitoring unit detecting a measuring voltage and outputting a request signal when the measuring voltage exceeds an upper threshold value. The synchronization unit outputs a synchronization signal to a synchronization terminal as long as the monitoring unit outputs the request signal, and otherwise to monitor the synchronization terminal for a synchronization signal. The control unit switches one of the two switching elements into a conductive state at least in sections during an activation period of time, when the monitoring unit outputs the request signal and/or when the synchronization signal is detected and is optionally recognized as valid by the monitoring.

Abstract: When assembling longitudinal seams, the shells in the region of overlap are moved together over lining-up drill holes, the shells are fastened and subsequently the pilot holes are transferred. Thereafter, these pilot holes are deburred, which involves temporary moving apart of the shells. According to one embodiment of the present invention a rib clamping device is stated that can be used for the longitudinal seam-structure assembly of an aircraft fuselage and that comprises attachment means and fastening means for non-positive and frictionally-engaged fastening of the shells. There is thus no longer any need to temporarily move the components apart.

According to the invention, an underside (6) of the base body (2) is in contact with a surface (13) of a component (12) for protecting said surface (13) and a base diameter (5) of the base body bore (3) is greater or equal to a diameter (15) of a bore (14) to be created in a component (12) or greater or equal to an opening diameter (17) of a countersink bore (16).

Abstract: A timing element for a lubricant supply system is capable of using pneumatics for the time of delivery of lubricant for a preset duration. In one example, the timing element has a cavity having an entrance and an exit, a first piston and a second piston. The first piston and the second piston are disposed in the cavity. The first piston is coupled to the second piston in such that compressed air in the entrance of the cavity is capable of moving the second piston and closing the exit. A pneumatic timing element may be incorporated into a dosing unit that is capable of supplying an amount of lubricant in a mist to a plunger bushing of a machine tool without. The duration of the dosing may be controlled solely by pneumatics and may prevent excess pooling of lubricant in bore holes by shutting off lubricant delivery at a preset time.
