    摘要: In order to reduce or avoid the discharge of gaseous pollutants H.sub.2 S and SO.sub.2 to the environment in a process for the production of slag sand (granules) from blast-furnace slag by granulation of the slag by means of a water jet, the propulsion jet interspersed with water vapor, granules and pollutants is injected directly into a water receiver, the residual vapor still remaining and the pollutants H.sub.2 S and SO.sub.2 not yet washed out are cooled down in a condenser in counter-current with spray water and condensed, and the residual gas remaining after the vapor condensation is taken off from the top end of the condenser and recycled via a recycle line back to the injector.

    摘要: A rolling bellows for pneumatic cushioning or shock absorption of a vehicle. Such rolling bellows are stressed particularly severely during telescoping in the pressureless state during assembly and also under emergency condititions. In order to avoid the occurrence of tension cracks from such causes, the rolling bellows are provided in the region of the cylindrical curvature, and on the inner surface, with integrally formed-on raised surface portions.
