Patent DE-4325050-A1 (DE)
Title: Circuit arrangement for starting a preheatable discharge lamp
Inventor: REISINGER HANS DR
IPC: H05B41/04
Filed: 1993-07-26
Abstract: In order to start a preheatable discharge lamp (LA') which is series-connected with an inductor (L1') and operated with AC voltage, a heating circuit is closed by means of a switching element (TR1') with a temperature-dependent resistance on zero crossing of the half cycles of a first polarity as long as the lamp (LA') does not burn. In a logic section, it is determined during the half cycle of a second polarity, which is opposite to the first, by means of the voltage which is present on the discharge lamp (LA') whether the discharge lamp (LA') burns. By interrupting the heating circuit, as soon as the voltage on the switching element (TR1') falls below a predetermined threshold value, a high-voltage pulse for starting the discharge lamp (LA') is induced in the inductor (L1'). <IMAGE>

Title: Vertically adjustable support for a floor shuttering
Inventor: MUELLER WILLI
IPC: E04G25/06
Filed: 1993-09-04
Abstract: By virtue of the telescopic extension of an upper tube 13 out of a lower tube 10, the support is vertically adjustable. In this arrangement, a plug-in bolt 14a is supported in the upper tube on two supporting surfaces 23b. The supporting surfaces are on a transversely displaceable plate 20. By displacing the plate to the left, the support can be relieved. In this arrangement, the plug-in bolt 14a slides onto the plate surface. The plate is of a U-shaped design and is closed on the open side by a screwed-on lug 24. Upon mounting, the plate is pushed on in the open state and is then closed by screwing on the lug. This design of the plate makes it possible to retrofit existing supports with such a plate without a rapid lowering operation. <IMAGE>

Title: Method for controlling the acceleration and drag torque slip in a motor vehicle
Inventor: DEBES MICHAEL
IPC: F02P5/15
Filed: 1993-10-11
Abstract: In a method for controlling the acceleration and drag torque slip in a motor vehicle in which, through the intervention of a traction control system in the internal combustion engine control system, the internal combustion engine torque is reduced in the event of acceleration slip and the internal combustion engine torque is increased in the event of slip due to the internal combustion engine drag torque, the traction control system intervenes in the form of an internal combustion engine torque demand on the internal combustion engine control system. The internal combustion engine control system then meets the internal combustion engine torque demand from the traction control system by co-ordinated intervention in the ignition control device, injection control device and/or charge control device of the internal combustion engine.

Patent DE-4418303-A1 (DE)
Inventor: HERTELENDI JOSEF
IPC: E01B29/17
Filed: 1994-05-26
Abstract: The flat railcar has a support frame (4) on bogeys (3) to carry lengths of rail. The rails are loaded onto the car via roller blocks (9) which are mounted on guides (10). The movement of the roller blocks is clamped by shear pins, or by limited torque couplings. If the loaded rail jams in the guides e.g. through a thick weld seam, then the shear coupling breaks and allows the block to move. The moving block is attached by a chain to a safety brake for the rail feed mechanism, to block further loading of the rail in the event of a jammed feed. The railcar is self propelled and has a driving cab at one end. Lateral drives swing the rail lengths into position on the bed of the railcar.
