Patent DE-3809789-A1 (DE)
Title: Crankshaft
Inventor: MAASS HARALD PROF DR
IPC: F16C9/02
Filed: 1988-03-23
Abstract: Known crankshafts have the disadvantage that their individual elements (main bearings, big-end bearings, fillet radii, crank webs) have different life expectancies due to the difference in loading. The crankshaft according to the invention is distinguished by the fact that the maximum stresses on the material at all the offsets of the crankshaft are essentially equal and that, at the same time, the minimum lubricating-film thicknesses of all the sliding-contact bearings are essentially equal.
Patent DE-3810445-A1 (DE)
Title: Brake pressure modulator for a hydraulic brake system
Inventor: KLEIN HANS CHRISTIAN
IPC: B60T8/42
Filed: 1988-03-26
Abstract: The pressure modulator piston (6), which defines the modulator chamber (5), interacts with a compressive force by way of a lever mechanism, the lever mechanism having a variable transmission ratio so that, irrespective of the position of the modulator piston (6), the force acting on the modulator piston is always in equilibrium with the compressive force. Only a small actuating force is necessary, therefore, in order to control the pressure in the modulator chamber. The invention relates to the provision of a counter-force, which is represented as compressive force, which acts on a pressure piston (20). The pressure in the chamber (19) is the master cylinder pressure, so that, providing that the master cylinder pressure is not varied during brake pressure control, the force acting on the modulator piston (6) and that acting on the pressure piston (20) are constantly balanced, so that only small actuating forces are ever required. <IMAGE>

Title: Text station
Inventor: JOERG PAUL-GERHARD
IPC: G06F3/0489
Filed: 1988-05-27
Abstract: In a text station, for instance a teleprinter, to guide the operator, processing menus for processing functions to be carried out and contents lists for documents to be processed are displayed.
