Abstract:
A tensioner for a power transmission element of a traction drive, includes a housing, a swivel arm having a free end for connection to a rotatable tension roller which rests on the power transmission element, and a swivel bearing, including an axle for connection to the swivel arm and a bushing forming part of the housing and supporting the axle, for rotatably supporting the swivel arm in the housing. A spring is positioned in a peripheral zone of the swivel bearing between the swivel arm and the housing. Mounted in fixed rotative engagement to the axle and supported by the housing via a friction lining is a friction disk, with a disk-shaped first dampening element positioned between the friction lining and the housing.
Abstract:
A linear induction motor, particularly for levitation-type vehicles (e.g., magnetic-suspension vehicles), has a stator juxtaposed with a reaction rail and formed with a plurality of longitudinally spaced windings or coils interdigitated with damping bars forming a damping cage with a pair of longitudinal conductors flanking the stator core. The latter is constituted by a lamination stack and is formed, in the region facing the reaction rail, with a plurality of slots in which portions of the coils are received. The slots increase in depth outwardly and the coils have portions which progressively recede from the reaction rail outwardly.
Abstract:
An arrangement for closing an opening in a vehicle and method for producing such an arrangement. In an arrangement for closing an opening in a vehicle, comprising a pane and an anti-shatter film attached to the pane, in the border region of the pane, the pane and the anti-shatter file are provided with a foam encapsulation. The foam encapsulation is arranged at least particularly spaced apart from an edge of the anti-shatter film, which edge is formed on the pane.
Abstract:

The pane (14) is a plastic pane and the frame is formed by in situ foaming (20) of a foam material onto the periphery of the pane, the shape of the pane, in at least one partial area of a connecting region between the pane and the peripheral foam, is configured such that a permanent mechanical, positive interlocking connection is created between the pane and the peripheral foam.
Abstract:
An exhaust gas aftertreatment device, including a bent exhaust pipe, a mixing pipe having a closed end at the exhaust pipe bend and a bell-shaped widened portion in at least partial contact with the exhaust pipe at its opposite end, and a nozzle connected to a receptacle in the mixing pipe closed end for injecting an additive into the exhaust gases, with a mixing one in the exhaust pipe between the urea nozzle and the exhaust pipe outlet in which the exhaust gases flow around the mixing pipe symmetrically and form a double eddy in the mixing pipe.
Abstract:
The invention relates to a method for mixing an exhaust gas flow with a fluid in an exhaust gas pipe 40 of an exhaust gas system 4, in which the fluid is injected by means of an injection device 5 into the exhaust gas pipe 40. The exhaust gas flow is guided in the exhaust gas pipe 40 in the area of the injection device 5 in a direction of flow S parallel to the exhaust gas pipe 40. The fluid is injected directly onto a deflection element 6 which is arranged in the exhaust gas pipe 40 in a central direction of injection E which deviates from the direction of flow S by an angle se, wherein by means of at least one sheet metal part 60 which is provided on the deflection element 6 and which is raised at least partially at an angle sv with reference to the direction of flow S, the exhaust gas flow is diverted with reference to the direction of flow S from its direction of flow S into a central direction of distribution V. Before and after it impacts the deflection element 6, the fluid is carried along at least partially by the diverted part of the exhaust gas flow into the direction of distribution V and is diverted into the direction of distribution V by the raised sheet metal part 60.

Abstract:
The invention relates to a method for preparing metallic workpieces for cold forming by contacting the metallic surfaces thereof with an aqueous acid phosphating solution so as to embody at least one phosphate coating and then coating the phosphate-coated surfaces with at least one lubricant in order to embody at least one lubricant layer. According to the inventive method, the phosphating solution essentially contains only calcium, magnesium, or/and manganese as cations that are selected among cations of main group 2 and subgroups 1, 2, and 5 to 8 of the periodic table of chemical elements in addition to phosphate. Furthermore, an alkaline earth metal-containing phosphating solution is free from fluoride and complex fluoride while the phosphating process is carried out electrolytically. The invention further relates to a metallic workpiece that is coated accordingly as well as the use of workpieces coated in said manner.
Abstract:
An injection molding machine is proposed, especially for injection stamping of large-area plastic moldings, comprising at least a first injection mold (13) which has two mold halves (15, 16) and which forms a first cavity (17) with a first projected area, and a second injection mold (14) which has two mold halves (18, 19) and which forms a second cavity (20) with a second projected area, one mold half (15, 18) of the two injection molds (13, 14) respectively being fixed on a common carrier unit (21) and for the two injection molds (13, 14) there being support means (22A to 25A; 22B to 25B) acting in the opening direction. In order to limit the force acting on the respective cavity, the support means (22A to 25A; 22B to 25B) depending on the respective projected area of the respective cavity (17, 20) partially take up the clamping force so that a holding pressure force acting on the material which has been injected into the respective cavity (17, 20) is set.
Abstract:
In view of the miniaturization of semiconductor components, the prevention of particles and other defects on the wafer surface during production is of great importance. The inspection should proceed as process-oriented as possible. For this purpose, devices are needed which on the one hand, are of very compact construction, while on the other hand, they still are equipped with measuring systems meeting the highest requirements.The device according to the invention for measuring surface defects, comprising a sample holder, a rotation drive for the sample holder, wherein the rotational axis runs perpendicular to the sample surface to be measured, an optical measuring system (10) for measuring scattered light, as well as at least one linear drive (23) for the measuring system, wherein the rotational direction is radial to the rotational axis of the sample holder, is capable of scanning the entire sample surface (16). By moving not only the sample, but also the measuring system, the need for space as a whole is reduced and the total device can be constructed with a more compact design.
