Patent DE-19801815-A1 (DE)
Title: Lean-burn i.c. engine exhaust gas cleaning process
Inventor: POTT EKKEHARD
IPC: F01N3/08
Filed: 1998-01-19
Abstract: A lean-burn internal combustion engine exhaust gas cleaning process comprises alternate exposure of catalyst portions to rich and lean exhaust gas in a relatively oxygen-rich exhaust gas. An exhaust gas cleaning process, for a lean-burn,  lambda  regulated internal combustion (i.c) engine with a NOx storage catalyst and a  lambda probe, comprises exposing each volume element of the catalyst at alternating times and locations to rich and lean exhaust gas when the exhaust gas is a stoichiometric or lean exhaust gas with relatively high oxygen concentration. The  lambda  value preferably oscillates about a mean value  lambda m of \-1, the oscillation being a sinusoidal or triangular oscillation of variable amplitude and/or frequency and the frequency being \-0.1 Hz. The mean value  lambda m is generated by cylinder-selective regulation of the engine, in which some of the cylinders are operated with different rich  lambda values and the others are operated with different lean  lambda values. Regulation of the lean exhaust gas is achieved by changing the fuel reduction rate or by varying the dead times of the injected quantity changes.

Patent DE-19808543-A1 (DE)
Title: Patient respiratory compliance, resistance and muscle pressure determination method system and appliance
Inventor: WEISMANN DIETER DR
IPC: A61B5/085
Filed: 1998-02-28
Abstract: The method involves occlusion of the patient's air way for a short period during an inspiration or expiration phase. At the commencement of the occlusion, the patients breath flow and volume of air drawn in or discharged are determined. During the occlusion, pressure in the airway is measured and change in the airway pressure is measured as a function of time.  Within the breathing cycle at different times the occlusion is initiated with several breaths and from the measured values the characteristic as a function of time of the change in muscle pressure is determined. This curve is then integrated with time to obtain the characteristic of the muscle pressure as a function of time.
