Abstract: The present invention relates to an admixture composition for the production of lightweight concretes containing polystyrene beads, which comprises a mixture of organic and inorganic substances which consists of the reaction products of polyurethane resin, tetraethyl orthosilicate, a glycol compound, an aromatic vinyl compound containing an unsaturated double bond, preferably styrene, and an inorganic silicate compound and preferably comprises the following components: glycol copolymer type compounds, in an amount of 15-10 w/w %, glycol polymer-silica type compounds, in an amount of 45-50 w/w %, polyurethane-based resin, in an amount of 13-22 w/w % polystyrene in an amount of 2-3% w/w %, and foam glass beads in an amount of 25-15 w/w %, and a) for the production of a liquid product, based on the total mass of the above composition, organic solvents in an amount of 15-20 w/w %, and water in an amount of 10-5 w/w %; or b) for the production of a solid preparation, based on the total mass of the above compositio

Abstract: The invention relates to an anti-roll torsion bar in a stabilizing arrangement in particular for running gears with rigid axle suspended with coil-plate, and/or pneumatic springs in public road vehicles, having draw bars on both sides of the vehicle, which are pivotally coupled to the chassis and the rigid axle.In accordance with the invention the draw bars have pivoted distance pieces which are lying outside the pivots connected to the chassis, where in the axis of the pin of the pivot is lying perpendicularly to the plane defined by the geometric axis of the torsion bar and the draw bar, respectively, and the torsion bar is supported in said distance pieces in a non-turnable manner, however so, that it could be displaced at least in one of said distance pieces in direction of the bar.
