Title: Motor vehicle longitudinal oscillation damping by injection correction - is based on difference between measured acceleration and computation from road speed, pedal position and gear ratio
Inventor: BURCKHARDT CHRISTOPH DIPL ING
IPC: F02D41/14
Filed: 1992-01-29
Abstract: An expected acceleration (aErw) is computed (2) by reference to a parameterised vehicle model from operating parameters of the combustion engine. The difference (aDiff) between this and the measured acceleration (aIst) is worked out (5) and a correction (dQ) is derived (6) for the quantity of fuel to be injected. The computer acceleration depends on road speed (vFzg), accelerator pedal position (PW) and engine speed (nMOT) after filtering (3) to suppress effects of irregularity. At starting, and when the engine is idling, such correction is either suppressed or computer from different parameters. ADVANTAGE - Unwelcome oscillations are reduced without detriment to starting and spontaneous gear-changing.

Title: Paper-making inlet correction - uses correlated measurements from start and end of water extraction stage to calculate the settings
Inventor: EGELHOF DIETER
IPC: G05D7/06
Filed: 1992-11-27
Abstract: To measure the effect of adjustment to the flow of fibre suspension from a stock inlet, the lateral layer thickness profile is measured at the start of the initial water extraction stage and the mass lateral profile of the web is measured at the end of the water extraction stage or at a further suitable point. The correlation between the two measurements is calculated. If there is a deviation in the mass without correlation with the layer thickness, then a counter corrective action for the fibre suspension concentration is indicated at the corresponding stock inlet section. With a deviation in the layer thickness without correlation with the mass, then a correction is indicated for the flow volume at the appropraite stock inlet section. It there is a deviation in both measurements, in the same direction, the suspension flow volume is corrected as indicated at the stock inlet section. With a correlated deviation in both measurements, in opposite directions, each deviation is treated as an uncorrelated shift. ADVANTAGE - The method gives a clear indication on a deviation of prod. quality, which of the two parameters has to be adjusted and in which direction.
