    摘要： Silica particles which are substantially spherical, have a particle size of 1 to 100 .mu.m, a very narrow pore size distribution and a low alkali metal content. The particles can be prepared by sol-gel technique using emulsification technique for drop formation. The process comprises a sol growth step in a basic environment based on ammonium or amines and a post-treatment in such an environment. The silica particles are particularly suitable for use in chromatography as they have very good particle and porosity properties and high purity.

    摘要： A motor vehicle clutch is particularly suited for a mechanical multiple-speed automatic transmission. The clutch comprises a pair of alternatingly engageable clutch discs (5,7) mounted on a pair of concentric shafts (8,10). In addition to a centrifugal arrangement (29,30) for engagement when starting, the clutch comprises a hydraulic control system with a piston cylinder device (20) and two three-way magnetic valves (51,52), one (51) of which is capable of presure regulation and the other (52) has merely an on-off function.
