Title: Method of correcting the center of gravity of a spacecraft involves moving isostatically attached masses parallel to all three axes of the spacecraft, gives high accuracy
Inventor: SCHAFHAUSER ERICH
IPC: B64G1/24
Filed: 1998-08-28
Abstract: The method involves moving masses to correct the center of gravity. Movable masses (1a,1b;2a,2b;3a,3b) are mounted in all three axes of the spacecraft so as to move parallel to the axes.

Title: Titration process to determine the concentration of a substance within samples taken without recalibration of the test instruments
Inventor: SPOHN UWE
IPC: G01N31/16
Filed: 1999-02-01
Abstract: The product flow is monitored by a detector which determines one or more of the reactants or an indicator, establishing the times or volumes at which the reactants and sample substance reach a defined preferably stoichiometric relationship capable of quantification. The concentration of the substances at the given times, the stoichiometric relationship in the reaction, the degree to which the reaction has been completed, and the reagent concentrations, are then calculated.  A continually-operated process generates a fluid flow from which samples are taken at regular intervals. A substance is present within the fluid sample (preferably less than 500 l) is determined without recalibration of the measuring instrument. Each discrete sample is drawn from the main process flow into a holding tube. The subsequent flow reversal generates two respectively inverse and preferably constant-flow samples surrendered to the reagent and dilution solutions. In the subsequent passage, the sample solution is mixed with the reagent.
