A line routing device is provided in order to allow simple, reliable electrical linking, in particular of a motor-vehicle sliding door to a vehicle power supply system. The line routing device includes a housing having a movement opening which extends in longitudinal direction and an outlet opening. A movement element is movably mounted in the movement opening and the cable as well as a spring strip, which is bent in a U-shape, are attached to the movement element. The cable is routed along the spring strip to the outlet opening and an end of the spring strip, which is remote from the movement element, is fixed to the housing.

An improvement to the phase interface process of preparing aromatic polycarbonate is disclosed. The process is characterized in that the phosgenation is carried out at 0 to 40° C., and in that the temperature of the reaction mixture at the time of addition of the catalyst at 10 to 40° C., and in that the molar ratio of aromatic dihydroxy compounds to phosgene at 1:1.05 to 1:1.20. The polycarbonate thus produced is characterized in its low content of carbamates, making it particularly suitable for the preparation of optical storage media.

A polycarbonate resin comprising fluorescing particles that feature a particular size distribution is disclosed. The size distribution of these particles that fluoresce upon excitation at wavelengths of 400-440 nm, 50× magnification and illumination time of 40 msec per scan was found to be critical in determining the suitability of the resin for optical, particularly optical storage, applications.

A polymeric material suitable for making a substrate for optical data storage disks is disclosed. The material, preferably aromatic polycarbonate is characterized in that the potential on 95 to 100% of the total surface of a disk molded therefrom is from −1.5 to +1.5 kV, and in that the potential on 0 to 5% of the total surface of said disk is between −1.5 and −2.5, and +1.5 to +2.5, and in that the potential on no more than 1% of the total surface of said disk is less than −2.5 kV and more than +2.5 kV. The potential measurements are carried out by means of a Monroe probe at a distance of 3.5 mm from the surface of the disk, the scanning region is in each case 12 cm in the X- and Y-direction, and in each case in steps of 2 mm in the X- and in the Y-directions.
