Abstract:
The arrangement controls a friction element for limiting a rotational speed compensation between the axles of a two-axle or all-wheel-driven vehicle as a function of the difference of the medium wheel speeds of both axles (longitudinal speed difference). This longitudinal speed difference is compared with two driving-speed-dependent tolerance bands, the first tolerance band being determining for positive and the second tolerance band being determining for negative longitudinal speed differences. If the values of the longitudinal speed differences are above the first or below the second tolerance band, the limiting is increased; if the values are within the tolerance bands, the instantaneous limiting is maintained; and if the values are between the tolerance bands, the limiting is reduced. This arrangement may also be expanded to include an adaptation device of the limit criteria with respect to different tread radii of the wheels and a cornering correction device.

Abstract:
The invention relates to a process for the preparation of insulins from analogs of preproinsulins, which comprises reacting preproinsulin analogs, at a pH below the isoelectric point of the insulins in the presence of trypsin or a trypsin-like endopeptidase, with an ester of natural amino acids or their derivatives and then cleaving off the ester group and other protective groups which may optionally be present.
Abstract:
