Patent number: 6936666Abstract: Continuous gas-phase polymerization process for preparing ethylene and propene homopolymers and copolymers, in which ethylene, propene or mixtures comprising ethylene or propene and C3-C8-?-monoolefins are polymerized in the polymerization zone of a gas-phase polymerization reactor at from 30 to 125° C. and pressures of from 1 to 100 bar in the gas phase in a bed comprising finely divided polymer in the presence of a catalyst. To remove the heat of polymerization, the reactor gas is circulated and firstly passes through a cyclone after leaving the reactor. To prevent polymer deposits in the circulating gas system, a catalyst poison having a boiling point above the maximum temperature within the circulating gas system is fed into this circulating gas system at a position between the reactor and the cyclone.Type: GrantFiled: October 29, 2002Date of Patent: August 30, 2005Assignee: Babell Polyolfine GmbHInventors: Shahram Mihan, Rainer Karer, Manfred Hecker, Philipp Rosendorfer, Kasper Evertz, Armin Lange

Patent number: 6068077Abstract: A power steering system, in particular for motor vehicles, includes a steering valve (15), for controlling a pressure medium for a servomotor, has two inlet seat valves (23, 24) and two outlet seat valves (25, 26), each with one closing body (31; 36). The closing bodies (36) of the outlet seat valves (25, 26) are actuatable via an actuating device as a function of a rotary motion of a steering-wheel shaft connected to an input member (10) of the steering system. The closing bodies (31) of the inlet seat valves (23, 24) are hydraulically pressure balanced with reference to a pressure of a pressure source, and by the force of locking springs (32) they keep the inlet seat valves (23, 24) closed in the neutral position of the steering valve. Each locking spring (32) is supported at one end on a closing body (31) of one of the inlet seat valves (23, 24) and on the other on the actuating device. The outlet seat valves (25, 26) are opened in the neutral position of the steering valve (15).Type: GrantFiled: June 10, 1998Date of Patent: May 30, 2000Assignee: ZF Friedrichshafen AGInventors: Armin Lang, Wolfgang Abele, Stefan Frohlich, Helmut Knodler
