Abstract: A method for measuring fault locations in high frequency cables and lines. A signal with the frequency f0 and a level a0 is emitted from the source. This signal is split up in the splitter and is routed to the same parts in the test piece (DUT=device under test) and to a sink. The signals of the source and the returning wave of the DUT are added, whereby the result of this addition is a signal with the frequency f0 and an amplitude a1. The value of the frequency f0 is changed, and the amplitude of the newly generated sum signal is, in turn, recorded. An inverse Fourier transformation transforms the signals from the frequency domain into the time domain. The transition point, which appears as the defined peak in the time diagram can thereby be located.

Abstract: L-Menthol is prepared from D,L-menthyl derivatives by enantioselective enzymatic cleavage.

The value of the frequency f0 is changed, and the amplitude of the newly generated sum signal is, in turn, recorded, whereby this is repeatedly carried out in an appropriate frequency domain (Span). An inverse Fourier transformation is applied to the measured values and transforms the signals from the frequency domain into the time domain. The transition point, which appears as the defined peak in the time diagram, can, as a result, be found located while taking the shortening factor into account.

Abstract: Plain oval cigarettes which issue from a maker in such orientation that the minor axes of their oval cross-sectional outlines extend vertically are advanced lengthwise in the spiral groove of a trough toward an outlet where the major axes of their oval cross-sectional outlines extend vertically. The thus reoriented oval cigarettes are attracted to the undersides of receptacles which are pivotably mounted on a rotary carrier and deliver the cigarettes, without any further changes in the orientation of the major and minor axes of their cross-sectional outlines, to successive peripheral flutes of a rotary drum-shaped conveyor which transports the cigarettes in such a way that the minor axes of their oval cross-sectional outlines extend radially of the rotational axis of the drum-shaped conveyor. This ensures that the oval cigarettes are more reliably held in their flutes during advancement with the drum-shaped conveyor.

Abstract: In order to determine the rotor resistance of a rotating field machine, a current is impressed in the stator via a field-oriented control, which current has a harmonic component above the nominal frequency of the machine. From the current, the rotor position and a readjustable parameter value for the rotor resistance, a current model calculates a field-parallel EMF component EF1, the harmonic component EF1.sub..about. of which is isolated. In addition, a voltage model calculates from the current and the voltage, the EMF vector as the current component reference value EF1' and its harmonic component EF1'.sub..about.. A correction control CR1 readjusts the parameter r.sub.R of the rotor resistance until the difference of the two isolated harmonic EMF components disappears. The test signal has practically no influence on the flux and the torque of the machine. At the same time, the stator resistance r.sub.S and the stray inductance x.sub.St can be determined.
