    Abstract: A system and method are provided for controlling or automatically controlling the driving dynamics of a two-track, two-axle motor vehicle having only one driven axle, which, for the rolling moment support, has a system for changing the distribution of the wheel contact forces to the left and right wheel respectively of each axle. The fractions of the rolling moment support taken over by the front axle and by the rear axle are changeable as a function of the drive torque provided by the drive assembly of the motor vehicle. For this purpose, a desired wheel contact force for the driven wheels can be determined from the drive torque, and by way of this desired wheel contact force, the distribution of the rolling torque support can be determined. A change of the distribution of the rolling moment support as a function of the drive torque of the drive assembly is preferably carried out only if the otherwise available contact force would otherwise not be sufficient for the transmission of the drive torque to the road. A slip control may be superimposed on this pilot control, which slip control seeks to minimize the deviation between the determined rotational speed difference of the driven wheels and the rotational speed difference corresponding to the respective driving condition.

    Abstract: A nuclear magnetic resonance (NMR) spectroscopy probe has a sample cell into and out of which a room temperature liquid sample may be directed. The cell is surrounded by a radio frequency coil that is used to perform NMR measurements of the liquid sample, and which is maintained at cryogenic temperatures. The coil is separated from the sample cell by a thermally insulative boundary, such as a vacuum. The sample may enter the cell through an input path, and may exit through an output path. The input path, output path and sample cell may be surrounded by a sheath through which flows room temperature gas. The ends of the sample cell may be tapered to promote thorough flow through the cell, and flow diverters may be included in the sample cell adjacent to the input and output paths to force flow to the outer wall of the sample cell.

    Abstract: The invention concerns an NMR sample holder for NMR samples with a short sample tube of constant diameter which is clamped in a largely gas-tight fashion and with a movable plunger and a rotor. The inventive device increases flexibility compared to conventional sample holders, reduces the vapor volume over the sample liquid in the sample tube and prevents deviations from precise orientation. The invention also concerns a method for simple and safe exchange of the sample tube thereby drastically minimizing loss through breakage.
