Abstract: A process is provided for mounting a joint arrangement, especially for a driven axle of a motor vehicle, as well as, furthermore, to a joint arrangement, especially for a motor vehicle axle. The joint arrangement has a joint fork (1), which can be arranged in the area of a vehicle axle, and a steering knuckle (2), which carries the wheel bearing (3) and is pivotable in relation to the joint fork (1) by two mounting points (4, 5). One of the mounting points is designed as a fixed bearing (4) and the other mounting point is designed as a movable bearing (5) with an outer ring element (8) and an inner ring element (9), wherein the movable bearing (5) has an axial degree of freedom as well as an additional pivot angle degree of freedom. The mounting process provides that the joint fork (1) and the steering knuckle (2) can be designed as one-piece components thanks to a bolt (20) and a space-maintaining auxiliary mounting element (18).

Abstract: The present invention relates to a catalyst composition and a method for making the catalyst composition of a polymerization catalyst and a static charge modifier. The invention is also directed to the use of the catalyst composition in the polymerization of olefin(s). In particular, the polymerization catalyst system is supported on a carrier. More particularly, the polymerization catalyst comprises a bulky ligand metallocene-type catalyst system.

Abstract: The present invention is directed to various methods and systems for detecting at least one impurity in a bulk fluid. In certain embodiments, the methods are performed in conjunction with a polymerization reactor system such as a gas-phase reactor system.

Abstract: In some embodiments, a method of monitoring a resin-producing polymerization reaction in a fluid bed reactor system to generate reaction parameter data in on-line fashion, determining an indicator of at least one of entropy and complexity (for example, Kolmogorov or Shannon entropy) of each of at least two subsets of the reaction parameter data, and optionally also determining from at least one value of the indicator (for example, from a time series of Kolmogorov or Shannon entropy values) an indication of at least one of degree of resin stickiness, an approach to or imminence of resin stickiness, and an approach to or imminence of an unsafe or undesired reactor operating condition (e.g., that can result in sheeting or chunking). Optionally also, the reaction is controlled in response to at least one value of the indicator, for example, in an effort to prevent the occurrence of sheeting or another discontinuity event or to maintain the reactor in a stable, non-sticking condition.

Abstract: A joint arrangement is provided for a wheel guide, especially for a driven, steerable axle of a motor vehicle. The joint arrangement includes a joint fork (1), which can be arranged at a vehicle axle or at a wheel carrier, and a steering knuckle (2), which carries the wheel bearing (3), wherein the joint fork (1) and the steering knuckle (2) are pivotably connected to one another via two mounting points (4), (5). At least one of the two mounting points (4), (5) of the joint arrangement has a toroidal roller bearing. Especially the wheel guiding and the axle geometry of driven, steered axles is improved with the present invention. While the mounting properties are improved, both the design effort for the wheel suspension and the space needed for the installation of the joint arrangement can thus be reduced.

Abstract: Embodiments of the present invention relate to operating a gas-phase reactor at or near maximum production rates and to measuring and controlling polymer stickiness in a gas phase reactor polymerization. In particular, embodiments relate to monitoring acoustic emissions in a reactor during gas phase polymerization to determine the onset of reactor stickiness and possibly discontinuity events such as chunking and sheeting resulting from that stickiness. Embodiments also relate to monitoring acoustic emissions to determine the need for effective control of parameters that minimize reactor stickiness and thereby preventing discontinuity events. The emissions are processed by arithmetic averaging.

Abstract: Processes for transitioning among polymerization catalyst systems, preferably catalyst systems that are incompatible with each other. In particular, the processes relate to transitioning from olefin polymerizations utilizing metallocene catalyst systems to olefin polymerizations utilizing traditional Ziegler-Natta catalyst systems.

Abstract: Embodiments of the present invention relate to measuring and controlling static in a gas phase reactor polymerization. In particular, embodiments relate to monitoring carryover static in an entrainment zone during gas phase polymerization to determine the onset of reactor discontinuity events such as chunking and sheeting. Embodiments also relate to monitoring carryover static to determine the need for effective additions of continuity additives that minimize reactor static activity and thereby preventing discontinuity events.
