Abstract: A device for an internal combustion engine includes a cell wheel and a blade wheel, which is mounted in the cell wheel so as to be relatively moveable and is actuated hydraulically by oil and via pressure chambers. The oil flows through axial lines into the pressure chambers, which are designed, on the one hand, between a shaft of an axial fastening screw, inserted from one face side of the camshaft, and a control sleeve, which envelops the shaft and rests in at least one receiving borehole, and is designed, on the other hand, between the control sleeve and a borehole, which is arranged coaxially to the latter and belongs to a hub. For an optimal design of the lines by the control sleeve and a simple assembly of the control sleeve, the control sleeve and the fastening screw, exhibiting the shaft, are inserted starting from the same face side, which control sleeve rests in corresponding receiving boreholes of the hub.

Abstract: An air guiding system is provided for an internal-combustion engine of a piston-type construction and includes an air filter and a feeding device for a suction system connected with cylinders of the internal-combustion engine. A receptacle, through which air flows, is arranged in a pipe between the air filter and the feeding device for influencing resonances. For optimizing the sound characteristics of the internal-combustion engine, the pipe is interrupted in the area of the receptacle, and a cross-section of the receptacle is larger than the cross-section of pipe sections of the pipe extending to the receptacle.

More particularly, the present invention relates to novel &bgr;-aryl-&agr;-oxysubstituted alkylcarboxylic acids of the general formula (I), their derivatives, their analogs, their tautomeric forms, their stereoisomers, their polymorphs, their pharmaceutically acceptable salts, their pharmaceutically acceptable solvates and pharmaceutically acceptable compositions containing them.

Abstract: A positional encoder assembly including a positional encoder, an interface unit releasably connectable with the positional encoder for connecting the positional encoder with a data bus, and connection elements providing for connection of the interface unit with the positional encoder and for disconnection of the interface unit therefrom upon displacement of the interface unit relative to the positional encoder.

Abstract: A system is described for reliable monitoring of clock rates, where a first processor which receives a first clock rate causes a counter to count using this first clock rate. A second processor which receives a second clock rate also causes another counter to count using the second clock rate. The readings of the counters are stored by the processors at predefined intervals in a common memory. Subsequently each of the processors loads the counter reading of the other processor, and compares it with its own counter reading. If both readings are within a tolerance range, one of the counter readings is used as a reference for all the other counters and the other counter readings are made equal to this reference value, so that subsequent monitoring of the processors is based on this reference value for the respective counters. If a reading is outside the tolerance range, an error is triggered.

Abstract: A device is provided for controlling the light distribution of a headlamp installation of a motor vehicle, with a first light source for an additional lamp and a second light source for a driving lamp. In order to provide a better device for controlling(the light distribution of a headlamp installation of a vehicle, it is provided that a light source for an additional lamp be mounted so that it can swivel. In this process, the light source for an additional lamp will illuminate part of the vehicle's own lane lying outside the edge of the roadway, while, in its second position, it illuminates the vehicle's own lane, preferably at a greater distance. The light source for the additional lamp is mounted in such a way that it has, at least, one common light passage area with, at least, one other light source.

Abstract: A reamer for the fine machining of surfaces of drilled holes in metal workpieces has a reamer body and at that body has at least one main blade and at least one auxiliary blade, a chip surface adjoining the blades at one side and a chip deflector step limiting the chip surface. That deflector step falls away in the zone of the auxiliary blade, exhibiting an increasing distance from the auxiliary blade. The chip deflector step rises in the zone of the main blade, exhibiting a decreasing distance from the main blade. The blades, chip surface and deflector step may be on a cutter plate attached to the reamer body or be part of the body itself. The invention also concerns that cutter plate.

Abstract: The present invention concerns a method and a system for feeding a reducing agent into a catalyst device. A first reservoir is provided and has a solid reducing agent, a second reservoir is provided and has a solvent for the solid reducing agent, and a reducing agent solutions is produced from the solid reducing agent and the solvent. The reducing agent solution is intermittently stored in a third reservoir, and the reducing agent solution is fed from the third reservoir into the catalyst device.

Abstract: A combustion engine cylinder head has at one wall of the cylinder head at least one hot site produced by the radiant heat of a combustion space. The hot site is cooled by a cooling duct, through which cooling water is flowing. To optimize the cooling of the hot site, an additional flow channel is provided, for a concerted flow of cooling water and for carrying additional cooling water in the cooling duct and for cooling of the hot site in the wall of the cylinder head.

Abstract: An underside of a motor vehicle, for example, a passenger car having cross-country mobility, is equipped with a covering device which has a covering part and a fastening system for the covering part which can be mounted on the underside, the fastening system having at least one spring element. In order to protect the covering part from damage when driving over an obstacle, the spring element is arranged between the underside and the covering part, the spring forces of the spring element acting approximately at a right angle with respect to the underside.

Abstract: The tobacco product carries on its surface catalytically active material for improving the burning process. The catalytically active material is selected from the group of crystalline and non-crystalline oxides and hydroxides of aluminium, e.g. gibbsite, having a particle size of 1 to 100 &mgr;m and a specific surface of 75 to 250 m2/g. With the use of the catalyst in the tobacco, the amount of noxious compounds in the mainstream and sidestream smoke can be considerably reduced in the combustion process of the smokers' article during its consumption.

Abstract: An optical position-measuring device is described, that includes a scale and a scanning unit movable relative thereto, a light source, one or more scanning graduations, at least one opto-electronic detector element and a mirror lens arranged downstream of the light source. The mirror lens includes a plane reflector surface and two partial surface areas having different radii of curvature. The beams entering through a first partial surface area impinge on the reflector surface and are reflected from the reflector surface in the direction of the second partial surface area. A collimated beam exists subsequent to exiting the second partial surface area.
