Title: IC engine control input voltage error corrected measurement - deriving accurate value of auxiliary parameter and replacement of reference parameter with derived digital ratio
Inventor: HALL DIETER
IPC: G01R19/00
Filed: 1990-04-25
Abstract: A method of error-corrected measurement of analogue electrical parameters as digital values, esp. of a voltage, involves comparing a base parameter of known value with its measured average value and using the deviations for correction. The electrical parameter and then immediately afterwards an essentially drift-free auxiliary value which is not accurately known are measured using the same device and converted to digital form by an ADC with an electrical reference input. A digital value ration is formed to eliminate the reference value and the correction value is determined to enable the exact value of the auxiliary parameter to be found. USE/ADVANTAGE - Accurate measurement of electrical parameter is achieved when the values of other parameter is achieved when the values of other parameters required for measurement are not accurately known.

Inventor: MENGES WILHELM DIPL ING
IPC: C02F3/28
Filed: 1990-12-29
Abstract: In the process, the thickening filtrate arising from the dispersion of waste paper is directly fed to a biological waste water clarification, in order by this means to prevent the excessive accumulation of a COD load in the waste paper dispersion water circuit and other production water circuit, by which means the end product produced can have a lower COD load and, as a consequence thereof, savings can be made, for example, in starch in a possible surface sizing. According to a first embodiment, the biologically clarified waste paper filtrate is immediately reused for waste paper dispersion. However, according to a second embodiment, the clarified waste paper filtrate is discharged as works waste water into the outfall and all of the surplus water from the paper factory is used for waste paper dispersion. It is further proposed to reuse the thickened clarified sludges in the waste paper dispersion.

Title: Multistage fluid cylinder - has fluid chamber between cylinder and primary piston, which forms closed system with secondary piston
Inventor: SUNDERMEYER WILFRIED
IPC: F15B15/16
Filed: 1991-03-14
Abstract: An inlet/outlet (22) connects a cylinder (10) to a hydraulic fluid source. An extending primary piston (14) within the cylinder (10) forms a cylinder for a secondary piston (40).
