Abstract: The invention relates to a method and device for transmitting light over a fat fiber (1) between optical components (B1; B2) of an optical measuring device, which are provided at a launching end (C) and at an extraction end (R; K; O) of the fat fiber (1). Said measuring device comprises a guiding means for the curved rigid guidance of a first partial section (PQ; FGHI; IJ; FL; LM; MN) of the fat fiber (1). If the radius of curvature of the curved guidance falls below a first limit, the light beam profile of the fat fiber (1) is homogenized by a mode mixing. In order to diminish the effect on the transmitted light caused by a permitted change in position of the fat fiber (1), a stiffening means, which is rigidly connected to the guiding means, is provided for rigidly guiding a second partial section (QR; JK; NO) of the fat fiber (1).

Abstract: A wheeled building and constructional machine of the mechanical shovel, bulldozer or the like type has an articulated steering system and comprises a vehicle chassis, a plurality of wheel axles, a hydraulic suspension system for the wheel axles, and at least one transversely stabilizing valve. The hydraulic suspension system comprises a plurality of fluid cylinders which are disposed between pivoting levers which are rotatably mounted and hold the wheel axles, and the vehicle chassis, and rotatably mounted on these vehicle parts. The fluid cylinders are adapted for action upon both of sides and are connected to the stabilizing valve or valves.
