Title: Device for the metrological registration of the strip tension in strip rolling mills
Inventor: KAMM THOMAS DIPL ING
IPC: G05D15/01
Filed: 1993-06-25
Abstract: In a known device for strip tension measurement in a strip rolling mill, a measuring roller bears on the strip to be rolled, being deflected against the strip by means of a piston-cylinder arrangement. The force exerted by the strip onto the measuring roller is measured with a measuring device. To simplify the device and increase the measuring accuracy, the measuring device has pressure pick-ups (16, 17) to register the hydraulic pressures (P1, P2) on both sides of the piston, with a computing device (18 to 25), connected downstream, to determine the strip tension (Fz) from the measured pressures (P1, P2). <IMAGE>

Title: Air suspension system
Inventor: GEIGER WINFRIED DIPL ING
IPC: B60G17/052
Filed: 1993-08-18
Abstract: An air suspension system is proposed which is provided with a lifting axle control. For operation of the lifting axle (3) individual valves (12, 13) can be operated merely by a pulse and precautions are taken in the form of one or more slide valves in combination with main valves so that the valve position attained at any one time is maintained even in the absence of current.

Title: Device for repairing a pipeline
Inventor: GRUENEWALD CLAUS
IPC: E03F3/06
Filed: 1993-10-26
Abstract: In the case of devices which have been known hitherto, a cylindrical basic body, whose outer surface consists of an elastic material and exhibits three chambers arranged axially one behind the other, is pushed into the pipeline and inflated until it butts against the pipe inner wall. These devices require a high outlay in terms of maintenance. Moreover, it is not ensured that the central chamber butts uniformly against the pipe inner wall over its axial length. The invention provides a device which, with high functional reliability, ensures that the pipe defect is completely filled. The device is easy to maintain and can also be quickly repaired on site. The device comprises three axially continuous hose sections which can be inflated independently of one another and are separated from one another by closure plates. The sealant introduced into the repair zone is pressed uniformly into the pipe defect. Device for repairing a pipeline, in particular a sewer line or the like.
