    摘要： A device is used for generating error signals for regulating the optical alignment of two lightwaves in connection with coherent heterodyne reception and comprises a receiver device (2, 3, 4) arranged focused opposite a front face at the end of a lightwave fiber (7) in order to make possible the transmission of the received information lightwave through the lightwave fiber (7) to an optical waveguide coupler (6), which is connected via a further lightwave fiber (13) with a local laser (12) and via two further lightwave fibers (8, 9) with respectively one detector (10, 11) for generating at least one error signal (Sr). A piezoelectric deflection unit (5) acts on this front face of the lightwave fiber (7) located in the focusing area of the receiving device.

    摘要： In connection with a method and a device for the control of the optical alignment of two lightwaves in the course of a coherent superimposed reception a spatial beam regulation is achieved in that the light of a local laser (5) is superimposed on the received light (1), that then the signal obtained in this manner is divided into two identical beam portions (1A, 1B) by means of a beam splitter (2) and that a respective error signal (14, 16) is generated from the two portions by means of a respective detector arrangement (3, 4), so that the two error signal portions result in a spatial error signal. The original data signal (15) is again obtained by the addition with the correct signs of the error signal portions.

    摘要： A process is described for preparing vinyl chloride polymers. The polymerization is carried out in an apparatus the inside walls and internal fitments of which have been coated with a reaction product which forms on reacting certain silanes with inhibitors for free-radical polymerizations and which contain in the molecule at least one aromatic or at least one quinonoid ring and at least one hydrogen atom which is bonded to an oxygen, sulfur or nitrogen atom with subsequent reaction with water, drying and heat treatment.The wall-deposit formation observed with the new process is markedly smaller, in particular after several polymerization batches, than in the case of known processes.

    摘要： The alignment device (10) is used for aligning an optical transmitting beam with an optical receiving beam. It comprises a rough alignment device and a fine alignment device. The rough alignment device has a first mirror (30.1), which can be rotated by approximately 360.degree. around a first axis (14), in respect to which the first mirror (30.1) is set at 45.degree. to the first axis. The rough alignment device furthermore has a second mirror (32.1), which can be rotated by approximately 180.degree. around a second axis (16), in respect to which the second mirror (32.1) is set at 45.degree.to the second axis. The second axis (16) can be rotated around the first axis (14), so that the second mirror (32.1) can be rotated within a spatial angle of approximately one hemisphere by the cumulative rotations around the axes (14, 16). The fine alignment device is constituted by a tiltable seating device (30.6 to 30.17) for at least one mirror (30.1), by means of which this mirror (30.1) is tiltably seated. The fine alignment device furthermore has an actuator device (30.18 to 30.19), by means of which the mirror (30.1) can be tilted in relation to its center normal line (15) within a spatial angle, which is considerably less than the hemisphere. At least the tiltably fastened one of the two mirrors (30.1, 32.1) is embodied with reduced mass.
