Abstract: A sealed anti-friction bearing, consisting of an inner bearing ring with a raceway arranged on its outer shell surface, of an outer bearing ring with a raceway arranged on its inner shell surface, and of a multiplicity of rolling bodies which roll between the bearing rings on the raceways, wherein two circumferential annular grooves are machined into the inner shell surface of the outer bearing ring axially on both sides next to the raceway in the outer bearing ring, in which annular grooves two seals are fastened which consist in each case of a circularly annular reinforcement and of an elastomer coating and which, on their inner circumference, comprise in each case one first radial sealing lip which bears against axial surfaces of two undercuts arranged on both sides next to the raceway in the inner bearing ring, in each case one second axial sealing lip which bears against radial surfaces of the undercuts in the inner bearing ring, and in each case one third sealing lip which forms a sealing gap together w

Abstract: A bearing element for two spatial directions, including a series of first rolling bodies (1), which roll on a first side (2) of an intermediate part (3) in a first direction, and a series of second rolling bodies (4), which roll on a second side (5) of the intermediate part and on a fastening part (6) in a second direction that differs to the first direction, the fastening part having a shaft (7), and a spring element (8) being arranged around the shaft. This bearing element addresses the problem of providing a bearing element for two spatial directions, which can absorb great forces perpendicularly to the two spatial directions and which is of compact design.

Abstract: A bearing arrangement for the rotatable mounting of a shaft (7) in relation to a housing (8), including a back-up bearing (9) which is designed as a rolling contact bearing, wherein the rolling contact bearing can absorb forces in the axial and radial direction and is designed in particular as an angular rolling bearing, especially as a two-row angular ball bearing, wherein the rolling contact bearing (9) is substantially left open in the radial direction. The object addressed by the invention is that of providing a bearing arrangement with a back-up bearing for a shaft, which bearing arrangement can better absorb in particular the forces occurring in the mounting of rapidly rotating, solid shafts.

The problem addressed by the invention is that of providing a bearing arrangement with a back-up bearing for a shaft, which bearing arrangement can better absorb in particular the forces occurring in the mounting of rapidly rotating, solid shafts.

Abstract: This invention relates to methods and compositions useful for delivering antigens to dendritic cells which are then useful for inducing T antigen specific cytotoxic T lymphocytes. This invention also provides assays for evaluating the activity of cytotoxic T lymphocytes. According to the invention, antigens are provided to dendritic cells using a viral vector such as influenza virus which may be modified to express non-native antigens for presentation to the dendritic cells. The dendritic cells which are infected with the vector are then capable of presenting the antigen and inducing cytotoxic T-lymphocyte activity or may also be used as vaccines.
