    • Polymers of a poly(meth)acrylic acid main chain in which, based on the main chain, 0 to 30% by weight of the (meth)acrylic acid basic building blocks may be replaced by maleic acid (anhydride) basic building blocks, fumaric acid basic building blocks or mixtures thereof and 0 to 10% by weight of the (meth)acrylic acid basic building blocks may be replaced by other copolymerizable ethylenic basic building blocks,and C1-30-alkylpoly-C2-4-alkylene glycols, bonded to the main chain via ester groups, having an average molecular weight of from 250 to 10 000 as side chains,where, based on the polymer, 1 to 19% by weight of the main chain and 81 to 99% by weight of the side chains are present and this ratio and the average molecular weight of the side chains are chosen such that free carboxyl groups are present in the polymer,are used as controllable dispersants for detergents or cleaners or constituents thereof.

    • A process for producing secondary amines of the formula R1R2N—A—NH—A—NR1R2, where R1 and R2 are linear or branched C1-20-alkyl radicals, optionally substituted with from 1 to 5 phenyl groups; or cyclohexyl radicals; or together with the nitrogen atom to which they are bound, form a 3 to 7 membered saturated ring, optionally containing further hetero atoms selected from the group consisting of N, O and S, and optionally substituted with from 1 to 5 C1-2-alkyl groups. The group A is a linear or branched C2-20-alkylene group, optionally containing from 1 to 5 phenylene groups; or a radical of the formula —CH(R3)—[CH2]k—X—[CH(R3)—[CH2]k—X]m—CH(R3)—[CH2]k—, where R3 is H or CH3, X is O, S or NR4, R4 is H or a linear or branched C1-4-alkyl group, k is 1 or 2, and m is an integer from 0 to 4; or a group of the formula where n, o, p, and q are, independently, integers from 1 to 4. In this process, primary amines of the formula R1R2N—A—NH2 are reacted in the presence of hydrogen and a catalyst comprising at least one element or compound of an element of groups VIII and IB of the Periodic Table, preferably group IB, and in particular, Cu. Through this process, a high selectivity of the desired amines can be achieved.

    • Double closing unit of an injection molding machine has a pair of movable mold mounting plates and a stationary mold mounting plate having a pair of stationary mold faces, aligned between the pair of movable mold mounting plates. Two pairs of bar members and a pair of locking units are provided so that each locking unit couples one of the pair of movable mold mounting plates to one of the pairs of bar members. A pair of pressure cushion systems located in the stationary mold mounting plate are each connected to one of the pair of movable mold mounting plates, the pair of pressure cushion systems being independent of each other. At least one pair of fast-motion cylinders is also provided, at least one cylinder being connected between each movable mold mounting plate and the stationary mold mounting plate. The cylinders hold one of the movable mold mounting plates in a closed position when the other movable mold mounting plate is in an open position.
