Abstract: A support system includes supporting legs, adjustable at least vertically in their longitudinal extent, to provide support on a substrate, a controller for controlling drives of the supporting legs using control commands, and an inclinometer for sensing an inclination of a carrier vehicle and/or of a lifting apparatus relative to at least one predetermined or predeterminable spatial direction and/or spatial plane. A method for supporting the carrier vehicle, parked on the substrate, for a lifting apparatus with a support system includes a calculation method step in which a sequence of control commands is calculated, and a levelling method step in which sequential and time-limited control of individual drives of the supporting legs takes place so as to minimize the inclination. The calculation method step and the levelling method step being repeated in a loop.

Abstract: Flame-retardant fibers of regenerated cellulose are produced by adding one or more flame-retardant phosphorus compounds to the viscose, extruding the viscose into a spinning bath and, if desired, stretching and after-treating the resulting filaments or staple fibers. The flame-retardant agent is a compound of the general formulaPN.sub.x O.sub.yin which x stands for a number between 0.9 and 1.7 and y stands for a number between 1.2 and 0, where the y-values converge towards zero as the x-values increase. The flame-retardant agent is more particularly used in a proportion approximately between 5 and 30 weight %, based on the weight of the cellulose.
