Abstract: Disclosed is a planetary traction drive for a driven turbocharger that utilizes angular contact ball ramps to provide variable clamping depending on torque throughput. The ball ramps are located between ring rollers and a ring gear, and function to locate the ring gear concentrically to the ring rollers. The angled contact axes of the ball ramps allows use of a low conformity contact between the balls and ball races in the ball ramps to provide efficient movement, while simultaneously locating ring gear concentrically to the traction rings.

Abstract: A wedge loading mechanism for an eccentric planetary traction drive in which a roller having a flexibly mounted shaft is positioned between two raceways forming a convergent wedge. Rotation of either of the two raceways wedges the roller within the convergent wedge squeezing the roller between the two raceways thereby transmitting rotational motion and torque between the two raceways. The flexibly mounted shaft generates differences between an effective supporting stiffness of the roller and an contact effective stiffness at the points where the roller contacts the two raceways. The difference in the effective stiffness allow the roller to operate efficiently at smaller convergent wedge angles.

Abstract: Nucleoproteins comprising overlapping homologous DNA sequences coated with a recombinase are employed for introduction into cells to produce double D-loop structures. The sequences may be modified with various moieties which result in modification of DNA. Formation of the D-loops results in inhibition of replication and transcription, where the moieties can be employed for permanent scission or modification of the DNA. The methods and compositions can be used for investigating physiological processes, for producing animal models, and for inhibition of an undesirable phenotype in vivo.

The two cups have tapered raceways which are presented inwardly toward the cone raceway. The transfer rings on their peripheral surfaces are tapered and slightly crowned. The cage includes end disks which lie beyond the ends of the transfer rings and studs which connect the end disks and further serve as journals for the transfer rings, thus maintaining the rings at equal circumferential intervals. The two cups are held together, and springs, either at the rollers or along the cups, urge the tapered raceways of the cone and cups and the tapered peripheral surfaces of the transfer rings snugly together.
