    Abstract: A process for the production of polyurethane foams by reacting a reaction mixture consisting essentially ofa) a polyisocyanate component, withb) a polyol component free from salt groups, in the presence ofc) at least one blowing agent,d) salts of ester-functional .alpha.,.beta.-unsaturated carboxylic acids and, optionally,e) other auxiliaries and additives typically used in polyurethane chemistry.Component d) the salts of ester-functional .alpha.,.beta.-unsaturated carboxylic acids are the reaction products of (i) monohydric or polyhydric alcohols, with (ii) unsaturated dicarboxylic acids or unsaturated dicarboxylic anhydrides, which contain on a statistical average at least one alkali metal carboxylate group and at most 0.5 alcoholic hydroxyl groups per molecule. The present invention also relates to the composites produced by back-foaming of a plastic film as a surface layer wherein the foam is produced by the process described above.

    Abstract: A suction hose for vacuum cleaner includes a tubular inner part, a jacket part and a locking device. The inner part is variable in length and includes a hose wall having a coil spring integrated therein, the coil spring being configured to automatically return the inner part from an extended position to a shortened position. The jacket part is configured to completely receive the inner part when the inner part is in the shortened position, the jacket part including a tubular shape. The locking device is configured to fix the inner part, in the shortened position, in the jacket part. The locking device includes a tubular member configured to surround the inner part, the tubular member including a first part of a first snap-fit device configured to cooperate with the jacket part so as to connect the tubular member and the jacket part.
