A wiper blade is proposed which is a part of windshield wiper systems of motor vehicles and is used for cleaning windshields of motor vehicles. The wiper blade has a multi-link elongated support bow system for a wiper strip resting against the windshield and has at least one upper support bow, on whose at least one end a lower support bow is hinged by means of a hinge bolt disposed transversely to the long extension of the support bow, wherein the upper bow of a U-shaped cross section in the area of the hinged connection extends with its U-shaped legs over a section of the lower bow of a U-shaped cross section in such a way, that the U-shaped legs of the two support bows essentially lie parallel with each other. The hinge bolt fittingly projects through the U-shaped legs in openings which are coaxial in respect to each other and the hinge bolt is provided with means for securing it against axial displacement in its center area located between the U-shaped legs of the lower bow. The securing means are connected in one piece with the hinge bolt made of an elastic material and can be deflected against a spring force at least as far as the surface area of the bolt, wherein the securing means have detent shoulders located between the U-shaped legs of the lower bow and facing away from each other, which cooperate with counter-shoulders of the lower bow facing them. It is assured in this way that the lower bow as well as the upper bow are always smoothly pivotable in respect to the hinge bolt.

A variable dashpot for motor vehicles A cylinder (2) full of vibration-suppressing fluid accommodates a piston (3). The piston is provided with vibration-suppressing valves, is fastened to a piston rod (8), and separates the cylinder into two compartments. The compartments communicate through a bypass. The cross-section of the bypass can be adjusted with a component (11) comprising a stator (12) with windings (13) and an electric motor (10) with a rotor (17). The improvement comprises making it possible to continuously and highly dynamically vary the cross-section of the bypass in a dashpot of the same size. This is attained in that the stator windings are accommodated directly in a recess (9) in the piston rod, which is made out of a material that can be magnetized, and the rotor is provided with permanent magnets (22), activates the adjusting component (11), and is accommodated in a bore in the stator (12).

The present invention refers to an electric motor including a tubular housing member and at least one cover secured thereto, said cover having an insertion area, which is inserted in the housing member in an essentially tight-fitting manner and which is connected to said housing member by means of at least one deformed portion of an end face area of said housing member. This kind of connection between the cover and the housing member is to be improved. This improvement is achieved by the features that the cover abuts on an end face of the housing member via a flange and that it has at least one opening in the transition region of the insertion area and the flange, said opening being accessible from outside via an access opening and forming an undercut portion at the insertion area, a respective portion of the end face area of the housing member being deformed into engagement with said undercut portion by moving the ram into said access opening, whereby the cover is locked in position on said housing member. One advantage of the present invention is to be seen in the fact that only the housing member has to be deformed for establishing the connection. In addition, the cover itself acts as a stop member so that the housing member can have a very simple structural design.

In a windshield wiper device each wiper blade has a wiper element with a lip applied to a windshield to be wiped and a back portion held in an elastic rail made from elastic plastics. The wiper element is secured on the elastic rail against mutual displacement in the direction of elongation of the rail. A two-part yoke system which engages the elastic rail provides for a uniform distribution of contact pressures exerted on the wiper elements.

A method for assembling a stator for an electric machine having a permanent magnet for generating a magnetic field in an air gap. Assembly of the stator is performed with the aid of a plunger, the cross section of which corresponds to the cross section of the air gap. The permanent magnet is slid into the interior of the plunger, whereas the flux return ring is slid over the same. The so formed sub-assembly is put into a casting mold adapted to be filled with a plastic material, which in its cured or hardened state forms a casing intimately surrounding the outer surface of the flux return ring and forming a face plate, to which the permanent magnet adheres. When the plastic material has set, the casting mold is opened and the plunger is retracted from the sub-assembly, resulting in a close toleranced cylindrical air gap space. After insertion of a bell-shaped rotor, a brush cover is assembled opposite the face plate. The flux return ring may be longitudinally slotted and biased so as to more intimately contact the calibrated tube during assembly in order to reduce the air gap tolerances. Instead of a plastic casing, a cup-shaped casing of malleable or deformable material may be used.

The invention relates to a management method for radio resources in a radio telecommunication system, in which a first radio telecommunication system has a first decentralized functional unit (serving RRM function) for managing radio resources, and a second radio telecommunication system has a second decentralized functional unit (neighbouring RRM function) for managing radio resources. The first and the second decentralized function unit signal information with respect to a work load (load measurements) of the radio resources to a central functional unit for common radio resource management (CRRM function). The central functional unit (CRRM function) evaluates this information (load measurements) and signals information with respect to load targets to at least one of the decentralized functional units, said information being taken into consideration by the decentralized functional unit in an intersystem handover (ISHO).

The present invention refers to an electric motor comprising a stator with an internal permanent magnet and a tubular magnetic return sleeve surrounding said permanent magnet whereby an annular air gap is formed therebetween, said magnetic return sleeve being held at its axial and radial positions relative to said permanent magnet by a frame of plastic material injected around these two components and being connected to said permanent magnet by said plastic frame. The present invention aims at improving the manner in which the two structural components are attached to and positioned on one another. This is achieved on the basis of the features that said plastic frame extends approximately up to the outer circumference of said magnetic return sleeve, and that one end portion of said magnetic return sleeve has provided therein recesses having each at least two edges which extend towards each other in the direction of the interior of the sleeve, the plastic frame being anchored on said magnetic return sleeve by means of said recesses.

The present invention refers to a dc motor, in particular a micro dc motor, comprising a shaft and a collector element arranged on said shaft and consisting of a collector plate and a collector which projects from said collector plate beyond the shaft end, the collector element being extended beyond the collector so as to form a shaft section on the side facing away from the collector plate, said shaft section being adapted to have attached thereto an additional component part. In accordance with a preferred embodiment, the dc motor is provided with an incremental angle-position encoder comprising an encoder element, the encoder element being fixedly attached to the collector element, which is extended so as to form a shaft section, and constituting the additional component part.
