Abstract: The present invention relates to aqueous polyurethane-polyurea dispersions having two discrete maxima in the particle size distribution, wherein the maximum of the fine fraction is between 51 and 150 nm and the maximum of the coarse fraction is between 160 and 700 nm. The present invention also relates to a process for preparing the polyurethane-polyurea dispersions, to coating compositions containing these polyurethane-polyurea dispersions, and to coated substrates prepared from these coating compositions.

Abstract: In a magnet system with two coil systems of different mean diameter arranged coaxially with respect to the longitudinal axis of the system defined by the direction of the field in the homogeneity region, which are rotationally symmetrical and are arranged symmetrically about the transverse median plane of the system perpendicular to the longitudinal axis and can carry exciting currents which result in overlapping magnetic fields that compensate, at least approximately, for the dipole fields of the two coil systems, an operating mode selector switch device (22) configured as a superconducting network is provided, by means of which the magnet system (10) can also be switched, as an alternative to the operating mode which provides considerable dipole-field compensation in the outer space of the magnet system (10), to that operating mode in which the magnetic fields generated by the two coil systems (11 and 12) at the center thereof are aligned in the same direction. In a special configuration, the ratio B.sub.

Abstract: A plurality of sensors are located on one of the bodies, staggered by fixed distances from each other along the direction of relative movement. The sensors are responsive to a characteristic of the other body, for example to surface characteristics of a roadway. A sensed signal, picked up by a first, or leading sensor is time delayed for a predetermined time interval, and compared with signals received from all the other sensors. Upon optimum correlation, and with known time delay and distance between sensors, the relative speed can then be indicated by determining which one of the sensors picked up the signals which matched the time delay signal. The amplitudes of the signals can be dynamically equalized and the time delay itself changed to permit output over wide ranges, or with respect to different scaling units.
