Abstract: An apparatus is described for needling a non-woven (2) with at least one support (6) for a needleboard (4) held in a frame (12) and with two parallel eccentric drives (7, 8) which are disposed between the frame (12) and the needleboard support (6) and are made of two parallel eccentric shafts (9 and 10) each for the needleboard drive in the needling direction on the one hand and in the direction of passage of the non-woven on the other hand. In order to provide advantageous constructional conditions it is proposed that an intermediate support (13) is provided between the needleboard support (6) and the frame (12) and that the intermediate support (13) is guided with respect to the frame (12) and the needleboard support (6) with respect to the intermediate support (13) in circular paths by way of the two eccentric drives (7, 8) which are disposed on the one hand between the frame (12) and the intermediate support (13) and on the other hand between the intermediate support (13) and the needleboard support (6).

Abstract: A friction body of porous carbon, which is infiltrated with silicon and reinforced with carbon fibers, includes at least one separate friction layer on a core body. In order to protect the friction layer against damage by outbreaking, carbon fibers in the friction layer are shorter than carbon fibers of the core body. Accordingly, different possibilities for producing a friction body with short fibers in the friction layer are possible.

Abstract: The invention relates to effervescent compositions containing a dry extract of ginkgo biloba and an effervescent mixture. By dissolving the mixture in water a virtually clear and almost neutral solution is produced which is stable during the period of use.

Abstract: The invention concerns a method for preparing phosgene from diphosgene and/or triphosgene, by reaction on a catalyst comprising one or several compounds with one or several nitrogen atoms with a pair of deactivated electrons. The invention further concerns a device for preparing phosgene from diphosgene and/or triphosgene, for implementing said method.

Abstract: A multi-cylinder internal combustion engine with at least one cylinder row is equipped with a cylinder head housing containing intake and exhaust valves that feed combustion air to the cylinders and release combustion exhaust gases through an exhaust system via control devices in dependence of the position of the crankshaft. Devices for generating differing exhaust valve lift progressions of at least two cylinders arranged in one cylinder row are incorporated to reduce overlapping opening phases of these exhaust valves. The intake valve and the exhaust valve of one of the two cylinders are themselves in an overlapping opening phase. Thereby, a uniform filling rate of the cylinders with new gas is achieved, particularly on a V-8 engine with a 90°-bent crankshaft.

Abstract: A mounting for a shock absorber or a pneumatic spring of a wheel suspension at the body of a vehicle is supported by bearing bolts, which are held in a bearing element. The shock-absorber strut is set at an angle and, with its free upper end and with interposing the supporting element, is held in a bearing bushing, which has two bearing bolts, which lie opposite to one another on a swiveling axis and which are supported cardanically and/or pivotably in a support fastened to the vehicle. The air spring is mounted only over the bearing element, the supporting element being omitted.

Abstract: There is provided a composition for the care and maintenance of water-resistant surfaces, which contains the following components:

Abstract: An internal-combustion engine is equipped with a ventilation system which is used for ventilating the crankcase. The ventilation system cooperates with an oil separator, is connected with an intake pipe and, furthermore, is provided with throttles. For expanding the application range and optimizing the effect of the ventilation system, the latter comprises the crankcase ventilation and a turbocharger ventilation, the crankcase ventilation and the turbocharger ventilation being connected to a distributor unit assigned to the oil separator. The distributor unit has a first throttle and a second throttle. In this case, with the insertion of the oil separator, the first throttle is connected with a first pipe connected to the intake pipe; the second throttle is connected with the intake pipe by way of a second pipe. In the suction operation, the ventilation system operates by way of the second pipe and, in the charger operation, it operates by way of the first pipe.

Abstract: A tool having a base body is proposed, on which at least one cutter holder, preferably a rocker-type cutter holder, is mounted such that it can be adjusted transversely with respect to the axis of the tool. The cutter holder carries a cutter and rests via a pressure piece on a control chamfer, which is provided on a control sleeve which is mounted in the base body such that it can be displaced axially in relation to the pressure force. The tool is defined in that the movement of the cutter holder (35) is controlled by at least one centrifugal force-actuated element (44, 66).

Abstract: A device for changing the angle of rotation of a camshaft of an internal combustion engine relative to a driving wheel. The device includes an inner part, which is provided with bridges or wings, and is disposed rotationally movable in a cell wheel. The driven cell wheel has several bridges, which are distributed over the periphery and divided by bridges or wings of the inner part into in each case two pressure spaces. The change in the angular position is caused by applying pressure on or relieving pressure from the two pressure spaces. As an end position is approached, the adjusting movement is damped hydraulically by integrated damping means. These damping means are formed by the interaction of the mutually approaching bridges of the inner part and of the cell wheel.

Abstract: A scanning unit for an optical position measuring device that includes a detector system that has a first reference pulse signal detector region disposed along a measuring direction and a second reference pulse signal detector region disposed along the measuring direction. The relative disposition of the reference pulse signal detector regions in the measuring direction is selected as a function of the structuring of a reference marking field on a scale for generating a reference pulse signal. An incremental signal detector region is disposed along the measuring direction and between the first and second reference pulse signal detector regions to generate at least one incremental signal.

Abstract: The description relates to a facility for needling of fleece with at least one needle board driven to and fro in stitching direction, which can be additionally driven in pendulum fashion in fleece feed direction (15) by means of an eccentric drive, which is provided with a connecting rod (3) articulated to a rocker arm (4) and a connecting pitman (8) to the needle board effective on this connecting rod assembly. To be able to easily adjust the rocking amplitude of the needle board in fleece feed direction (15) it is suggested that the swivel bearing (5) of the rocker arm (4) is seated on a rotatable crank arm (6) and that, for adjustment of the rocking amplitude of the connecting pitman (8), the neutral rocking position of the rocker arm (4) is adjustable via the crank arm (6) between an end position essentially running in the direction of the connecting pitman (8) and an end position running transverse thereto.

Abstract: A brake disk made of a fiber-reinforced material includes two assembled friction rings. The friction rings, on interior sides, are provided with ribs. The two friction rings are supported with respect to one another along at least a portion of the ribs. In order to provide a suitable shaping of faces of the ribs, faces used as coupling faces are constructed such that a coupling of the friction rings is caused in precisely one rotating direction and, in a particular case, such that the coupling faces are arranged in an alternating manner.

Abstract: An apparatus for the control of a machine tool includes, for the processing of a workpiece, several separate processing units that can execute definite tasks simultaneously and independently of one another. Furthermore, a display unit, as well as at least one assigned input unit, is provided. On the display unit side at least one display window, which can be activated selectively and in which corresponding information can be presented visually, is assigned to each processing unit. The display window active at the moment is thus shown uncovered and/or marked for emphasis.
