Abstract: A process for the preparation of organopolysiloxane resins, wherein a silane R3SiOR1 ??(I) or a hydrolyzate thereof, and a silane Si(OR2)4 ??(II) or a partial hydrolyzate thereof, are reacted with acidified water and a portion of alcohol distilled off; the mixture is then reacted in the presence of base and a water-insoluble organic solvent and water, alcohol and optionally a portion of water-insoluble organic solvent are removed; the mixture is then neutralized with acid, and any water, alcohol, and a portion of organic solvent are distilled off; the mixture obtained is then treated with organopolysiloxanes and precipitated salts formed are then removed, and optionally, the mixture is separated from water-insoluble organic solvent.

Abstract: An anti-buckling control system is disclosed for articulated vehicles, especially articulated busses. Two double acting piston-cylinder units are interposed in the pivot connection between the forward and following vehicular units for applying resistance forces against hinged or buckling movement of the vehicular units with respect to one another. A computerized control unit is provided for controlling the hydraulic circuit for the piston-cylinder units so that they apply resistance forces tending to direct the buckling angle towards desired values determined in dependence upon the forward vehicular unit steering angle, the instantaneous buckling angle, and the vehicle velocity. The piston-cylinder units are disposed with their ends at one vehicle side closely adjacent one another and with their ends at the other vehicle side spaced from one another to form a V-shaped configuration.
