Abstract: Disclosed is a method for producing an aqueous polymer dispersion, according to which unsaturated monomers are first polymerized by means of suitable catalysts, whereupon the obtained polymers that are swelled with all or some of the remaining unreacted monomers are added to surface-active substances and water in a last step in which the obtained polymers are not entirely separated from the remaining monomers.

Abstract: Transition metal complexes having bulky ligand systems and the formula (I) where R2, R4 are C4-C16-heteroaryl or C6-C16-aryl bearing C4-C16-heteroaryl or C6-C16-aryl substituents in the two vicinal positions relative to the point of linkage to Na or Nb and M is a metal of group VIIIB of the Periodic Table of the Elements, are described.

Abstract: An air inlet conduit for a cooler of a vehicle has an air conduction scoop inserted into an opening of a vehicle body skin part on its air inlet side. The air inlet conduit is supported by way of a surrounding collar section on an exterior side of the vehicle body skin part, a scoop section extending away from an outer collar section of the air conduction scoop, which scoop section projects into a hollow space of the vehicle body skin part situated behind the latter. The air conduction scoop is connected to an adjoining closed flow-through conduit. So that, during the mounting of the air conduction scoop and/or of the flow-through conduit without any gauge and independently of worker skills, a constant gap is always ensured between the air conduction scoop and the adjoining vehicle body skin part, several trim lugs, which are arranged in pairs on the edge of the opening and project into the opening, are provided.

Abstract: An aerodynamically constructed covering part for the underside of a motor vehicle, particularly a passenger car, is provided with an inflow opening and an air guiding element arranged adjacent to the inflow opening. In the driving operation, a partial flow of the cooling air flowing through between the covering part and the roadway is guided through the inflow opening and the air guiding element situated at least in areas above the covering part to an assembly and/or a chassis part situated above. In order to simplify the fastening between the covering part and the air guiding element, it is provided that the air guiding element is inserted into a receiving opening of the covering part and is separably connected with the covering part by way of slide-detent connections.

Abstract: A bumper for vehicles, particularly motor vehicles, includes a dimensionally stable member and an elastic covering forming an end region of the vehicle body. At least one light respectively is inserted into laterally exterior receiving pockets of the covering and is held in position at the covering. The light has a light-transmitting covering element on the side facing the end region. It is provided that, on each covering element, a guard is provided locally which projects slightly with respect to the adjacent elastic covering and is constructed in one piece with the covering element. In the area of the guard, in the event of a 30° pendulum crash, the covering element is supported on a member structure of the vehicle body situated behind the covering element.

Abstract: A motor vehicle has at least one radiator which, on an input side, has a first air guiding duct with a cooling-air inlet opening and, on an output side, has a second air guiding duct with a cooling-air outlet opening. In order to be able to reduce the mounting expenditures and the fastening devices in the case of a radiator arrangement, it is provided that the at least one radiator is accommodated by a supporting frame fastened to the adjoining body, and in that an air guiding element is constructed in one piece with the supporting frame, which air guiding element, together with the radiator, forms at least one of the two air guiding ducts.

Abstract: A machine for cutting plate-shaped workpieces, incorporates a tool guide (7), an operating handle (13), and a cutting tool (6) which revolves along the tool guide (7). By moving the operating handle (13), the tool guide (7) with its cutting tool (6) can be shifted from an idle position into an active position. In its idle position the cutting tool (6) is disengaged from, and, in its active position it is engaged in, the workpiece to be processed. Provided between the operating handle (13) and the tool guide (7) is a gearing mechanism (14, 18) with a transmission ratio which varies with the movement of the operating handle (13) as a function of the position of the tool guide (7) and its cutting tool (6) relative to the workpiece.

Abstract: A method of correcting deformed turbine components (1) in an incompressible medium (4) is achieved via means of a pressure wave (6). The turbine component (1) is rigidly fixed to a matrix (3) containing a specified mold (2) and is put into the incompressible medium (4). The method may advantageously work at ambient temperature. It is quick, reproducible and cost-effective.
