Abstract: The present invention relates to an exhaust gas treatment system for reducing ammonia emission from a gasoline engine comprising a three-way conversion catalyst (TWC) or a four-way conversion catalyst (FWC), further comprising an ammonia oxidation catalyst (AMOx) or a selective catalytic reduction catalyst (SCR), and a method of treating exhaust gas from a gasoline engine with an exhaust gas treatment system capable of removing ammonia.

Abstract: A blow molding tool (1) for producing a plastic article, in particular a fuel tank, comprising at least one clamping frame (2) with mold clamping devices (3) and at least two blow mold halves, which are formed such that they can be moved together and apart by means of an opening and closing movement of the clamping frame (2) and which respectively have at least one cavity (8) for the forming of the plastic article, the blow molding tool (1) being distinguished by the fact that the mold clamping devices (3) respectively have at least one tool holder (6), in which a mold insert (7) is in each case exchangeably inserted, and in that the tool holders (6) respectively form a peripheral sealing edge (10).

Abstract: The invention refers to a method for the production of hollow bodies from thermoplastic, in particular for the production of motor vehicle tanks, in which the plastic is shaped as an extruded preform in the still plastic state or as a semi-finished product into at least two shells with the aid of at least one molding die (3), with the use of heat, and the subsequently cooled and then dimensionally stable shells are placed one on the other and joined together into an essentially closed hollow body. As molding die (3) is used at least one positive die which has essentially the contour of the shells. The shells are shaped by the plastic being laid against the positive die. The apparatus for carrying out the method is also disclosed.

Abstract: The invention relates to a construction machine, especially a road construction machine, comprising a machine frame and a chassis carrying the machine frame with several wheels, with at least one of the wheels being connected with the machine frame via a height-adjustable lifting column and the lifting column comprises a distance measuring device for measuring the adjustment of the lifting columns with a sensor. The invention further relates to a method for controlling and/or monitoring the working depth of a working device for processing the ground arranged on a height-adjustable construction machine, especially a road construction machine.

Abstract: The present invention relates to a process for the continuous production of a multi-layer web comprising an exterior covering and a nonwoven material disposed underneath. According to the present invention, a nonwoven material which has been prebonded is used as the starting product, and the steps of additional bonding, calibrating, and smoothing of the nonwoven material and of laminating the nonwoven material and the exterior covering are combined in a single process. The present invention, in addition to achieving a cost advantage, also produces a covering material that provides better sitting conditions, equivalent to the foam backed covering materials with respect to physical textile values yet being easier to recycle and. In addition, recycled textile products can be worked into the covering material of the present invention as reprocessed fibers without losing any advantage.
