Patent DE-4102075-A1 (DE)
Inventor: HEDDEN KURT PROF DR
IPC: B01D53/86
Filed: 1991-01-24
Abstract: A process is described for removing nitrogen oxides from an exhaust gas by selective reduction with ammonia in a catalyst zone, exhaust gas and ammonia flowing through the catalyst in one direction in one process section and in the opposite direction in a later process section, the ammonia being only fed at intervals, the exhaust gas flow direction being reversed prior to the exit of ammonia at the catalyst end and the process steps mentioned being alternately repeated. The process is characterised in that the site of entry of ammonia into the catalyst is arranged after the site of entry of the exhaust gas. This effects a high NO conversion without ammonia slip. <IMAGE>
Patent DE-4104992-A1 (DE)
Inventor: VORHOFF WERNER DR ING
IPC: E21B7/06
Filed: 1991-02-19
Abstract: To ensure the precise directional control of drilling rods (1), the invention proposes a device in which the drilling rods which transmits the pressure and torque to the bit, are surrounded by loosely fitting outer drilling rods (3). Near the bit, the outer drilling rods are fitted with an eccentric mounting (10) through which the inner drilling rods pass. Rotation of the outer drilling rods thus makes it possible to carry out any correction required to the course of the borehole. This is normally done by simply rotating the outer drilling rods from the borehole mouth. In order to determine the course of the borehole, the longitudinal inclination, transversal inclination and direction of travel of the drilling rods are measured.

Patent DE-4143159-A1 (DE)
Inventor: BUEHL HARRO
IPC: B60S1/34
Filed: 1991-12-28
Abstract: The invention concerns a windscreen-wiper drive unit, in particular a drive unit for vehicle windscreen wipers, in which the wiper drive shaft (1) executes a reciprocating rotational motion. In order that the change in direction does not take place abruptly, but in damped fashion, the inside end of the wiper shaft (1) is fitted, as in prior art wiper systems, with a pinion (2) with a gap (13) in it. Lugs (e.g. 11, 12) on a spring element (e.g. 7) project into this gap. Just before the change in direction, the end tooth (14 or 15) strikes the lug (11 or 12) located on the side nearest to it. This lug is pushed out of its position by the rotational motion of the pinion, thus damping the motion of the pinion. The spring element is preferably attached to the cover (6) over the drive unit.
