    摘要: Silica sols with a high content of microgel and particles with a specific surface area within the range 300 to 700 m.sup.2 /g, preferably 400 to 650 m.sup.2 /g. The sols can be prepared by acidification or a water glass solution and alkalization at a certain dry content, alternatively to a certain pH. The sols are particularly suitable for use as additives in papermaking in combination with cationic polymers and especially in combination with cationic acrylamide based polymers.

    摘要: In an arrangement for jointing together adjacent pieces of floor covering material, mutually facing edge portions of the pieces in a joint are profiled such that the one piece has a groove-shaped accommodation space in which a corresponding bead-shaped projection on the other piece may be accommodated. The one piece has a flocking which is disposed for holding together adjacent pieces. The profiling has, besides the accommodation space and the projection, mutually facing surfaces on both pieces, at least one of these surfaces being flocked. The flocking or flockings are located outside the defining surfaces of the accommodation space and the projection.
