Patent DE-19716089-A1 (DE)
Title: Variable displacement compressor for vehicle
Inventor: KAWAGUCHI MASAHIRO
IPC: F04B49/22
Filed: 1997-04-17
Abstract: The compressor has an inclined plate driven by the drive shaft to displace a number of pistons in a reciprocating motion. The displacement of the compressor is controlled by altering the inclination of the drive plate relative to the drive shaft. The displacement is determined by the operating load on the compressor, which is variable as a function of the difference between the inlet chamber and outlet chamber pressures.  The pressure in the chamber (37) where the plate acts on the pistons is coupled back (46,47) to the inlet chamber, and the delivery pressure is coupled back (48) to the drive chamber (37). A valve (49) in this second passage can be selectively opened and closed by a solenoid.

Title: Uni and multivariate method of data analysis in online process control using fuzzy logic
Inventor: ADLER BERNHARD PROF DR
IPC: G05B13/02
Filed: 1997-12-10
Abstract: The method involves allocating uni- and multivariate analysis values to a defined standard, To using fuzzy set algorithms. The data are allocated to a population of a statistical test or alternative hypothesis. The method involves allocating uni- and multivariate analysis values to a defined standard, To using fuzzy set algorithms. The allocation of the analysis data to a population of a test hypothesis or to an alternative hypothesis is met from associated values of one of the two populations. The population of the test hypothesis is obtained from a sample diluted by a matrix or water. The alternative hypothesis is for a sample increased by a predetermined standard value. The diluted sample is obtained by ultraviolet photochemical decomposition of the analyte in an analysis sample, or may be sequestered by a chemical reaction or may be removed from the sample using an absorber. If the defined standard, To, is a detection limit, the distribution of blank values can serve as the test hypothesis. If a measuring unit comprising a number, n, of equal sensors is used, the analytical signal is produced from local mean values, in which case the standard deviation of the device, and with it the population width, is reduced by a factor of 1/ square root of n, and the risk of misinterpretation is reduced. Only three calibration points are required. The continuous sample flow is arranged, so that a ring flow is produced, and the sample increase for the alternative hypothesis is produced in preselected time intervals.
