Title: Ignition device for a piston internal combustion engine with applied ignition, especially of motor vehicles
Inventor: HEUSER EDGAR
IPC: F02P7/02
Filed: 1988-08-06
Abstract: An ignition device for a piston internal combustion engine with applied ignition and cylinders arranged in banks, especially of motor vehicles, has an ignition coil generating the required high voltage and an ignition distributor electrically connected thereto, the rotor of which is driven by the camshaft. The ignition distributor has a tubular distributor housing composed of a high-voltage insulating material running in the direction of the cylinder bank of the internal combustion engine with electrical junctions corresponding to the number of cylinders and arranged one after another in series on a level with the individual cylinders. A distributor shaft supported in the distributor housing functions as rotor of the ignition distributor, which shaft on its circumference has contacts staggered according to the number of cylinders and the firing order, which are electrically interconnected and connected to the ignition coil and interact with the electrical distributing poles of the distributor housing. This elongated ignition distributor results in electrical connections of equal length from the distributing poles to the individual cylinders of the internal combustion engine.

Title: Brake disc for rail vehicles
Inventor: GEBHARDT HANS DIPL ING
IPC: B61H5/00
Filed: 1989-01-30
Abstract: Brake discs for rail vehicles have, in their design as axle-mounted brake discs, in each case one friction ring (13) which can be attached to a hub (5) and can be acted on on both sides by brake clips (15, 17), it being possible to pull onto a shaft (13) of the rail vehicle a hub (5) which bears the friction ring, or to attach it to the shaft in some other way. Clamping sleeves (19) which serve to attach the friction ring to the hub extend radially in receiving holes both in the friction ring (3) and in the hub (5) such that the braking torque can be transmitted from the fraction ring to the hub (5) and thus to the shaft (13). In order to replace the friction ring (3), the clamping sleeves (19) can be pulled out radially from their receiving holes with the aid of an extraction tool; in each case an extraction sleeve (29) which is secured in a rotationally fixed and axially non-displaceable fashion is provided at the preferably radially inner end of the clamping sleeves (19), which extraction sleeve (29) has an internal thread (35) for turning in the extraction tool. <IMAGE>
Patent DE-3904525-A1 (DE)
Title: Process for lining pipelines
Inventor: KLEMM GUENTER DR ING
IPC: F16L55/165
Filed: 1989-02-15
Abstract: In order to repair a buried pipe (10), a hose (11) is introduced in the deformed state into the pipe. The deformation is obtained in that the hose, closed at its ends, is evacuated. After laying, the vacuum is removed and, due to its restoring capacity, the hose assumes its original state by coming to bear against the pipe wall and forming a dimensionally stable lining. A second variant of the process provides that the hose is stretched when it is drawn into the pipe and that the hose circumference is consequently reduced temporarily. <IMAGE>

Title: Rotor for helicopters and model helicopters having controllable backpressure compensation, while at the same time increasing the forward propulsion speed
Inventor: DIETZ WERNER
IPC: B64C27/46
Filed: 1989-05-02
Abstract: A rotor is described for helicopters and model helicopters, in the case of which rotor ram air, which is required specifically in each case, is produced in the rotor region by mechanical and/or electronic control, which ram air not only compensates for the difference in effect between rotor blades which are moving forwards and those which are moving backwards, but at the same time also makes it possible to increase the forward propulsion speed of the helicopter. These technical and design improvements and simplifications, by overcoming the asymmetric backpressure in the rotor region, but especially as a result of the additional capability to increase the forward propulsion speed as well, open up a considerably extended operational capability for helicopters in comparison with powered fixed-wing aircraft.
