    摘要: Aqueous dispersions of polyurethanes which are crosslinkable by the action of high energy radiation contain (a) a polyisocyanate, (b) a polyol having a molecular weight of from 400 to 6,000 g/mol, (c) if required, a polyol having a molecular weight of from 62 to 399 g/mol, (d) if required, a polyamine having two or more amino groups which are reactive to isocyanate, (e) if required, an aminoalcohol having one or more amino groups which are reactive to isocyanate, (f) a compound containing ionic groups or groups which can be converted into ionic groups and one or more hydroxyl or amino groups which are reactive to isocyanate (g) if required, a monofunctional polyetheral and (h) a compound having one or more ethylenically unsaturated groups and one or more hydroxyl groups. The compound having an ethylenically unsaturated group (h) is used in amounts corresponding to 0.02-0.08 gram equivalent, based on the polyisocyanate (a), of OH, and the polyurethane, dissolved in dimethylformamide, has a Fikentscher K value greater than 40 or is insoluble in dimethylformamide.

    摘要: The invention relates to a hydraulic drive, especially for two-cylinder thick matter pumps. Said hydraulic drive comprises at least one main pump (10) embodied as a hydraulic variable displacement pump, and two hydraulically actuatable drive cylinders (20,22) that are each connected to a connection line (16,18) of the main pump (10) by means of pump connections mounted on one end thereof, forming a closed hydraulic circuit, and communicate with each other at the ends thereof opposing the pump connections (24,26) by means of a swinging oil line (28). The hydraulic drive also comprises a feed pump (42), by which means pressurized oil is fed from an oil tank to the current low-pressure side into the hydraulic circuit, and a flushing branch (52), by which means a flushing oil flow is branched off from the current low-pressure side under a limited pressure into the oil tank (44). In order to avoid low-pressure influxes during the reversal process of the main pump (10), the flushing oil flow is blocked and then released in a time-delayed manner during each reversal process of the main pump (10), independently of the differential pressure in the connection lines.
