Abstract: The present invention is directed to a monomer for chain growth polymerization, in particular anionic polymerization, said monomer having the general formula (EFL) wherein: Ra is a C1-C30 alkyl, C3-C30 cycloalkyl, C6-C18 aryl or C2-C12 alkenyl group. The present invention is further directed to a process for the anionic polymerization of at least one compound (EFL) as defined above, wherein said anionic polymerization is conducted in the presence of an initiator selected from the group consisting of: alkali metal organyls; alkali metal alkoxides; alkali metal thiolate; alkali metal amides; and compounds of an element of group 3a of the Periodic Table of the Elements. The process of anionic polymerization yields a homo- or co-polymer (p-EFL) having pendant lactone functional groups in its repeating units.

Abstract: A scheme for ultrafast magnetization reversal in an in-plane magnetized layer (3) is disclosed. For that, an external magnetic field {right arrow over (H)}ex is applied such that the magnetization {right arrow over (M)} precesses around the external magnetic field {right arrow over (H)}ex and the external magnetic field {right arrow over (H)}ex is maintained until the precession suffices to effect the magnetization reversal. The external magnetic field {right arrow over (H)}ex is applied approximately perpendicular to the magnetization {right arrow over (M)}.

Abstract: A rolling bearing arrangement for an anti-locking brake system has a pulse ring with projections directed toward the fixed ring. The surfaces of the projections that activate the pulse generator are cut during the hard working of the bearing ring. The pulse generator is integrated in the rolling bearing arrangement. Thereby, on one hand, tolerance limited operational differences in the amplitude and shape of the pulses are avoided, especially during slow rotational speeds of the bearing ring. Furthermore, external influences on the pulse generator and pulse ring caused by rough roads do not occur due to the hermetic encapsulation of the sensitive components.

Abstract: A rolling bearing assembly capable of withstanding large vibrations especially adapted for use in heavy construction equipment such as steam rollers. The assembly comprises inner and outer rings, one of which is detachable or removable. The rings have guide flanges adjacent opposite ends on either side of the space for the rolling elements. A groove for an O-ring is formed in at least one of the confronting surfaces of the guide flanges. The groove is preferably the same or greater cross section as the cross section of the elastic O-rings positioned with initial stress between the surfaces.
