Abstract: Bearing systems for high speed rotating shafts, such as turbocharger shafts, include a first ball bearing in one end of an elongated cylinder capable of carrying axial thrust in both directions and a second ball bearing in the opposite end of the elongated cylinder with its outer race slideably mounted in the cylinder against the biasing force of a preload spring. The second ball bearing is free to move axially with the shaft upon axial expansion of the shaft when exposed to high temperature. The inner races of the ball bearings are clamped to and rotate with the shaft as part of the rotating assembly.

Abstract: The performance of a computer system displaying polygonal forms is improved by method and apparatus including a cache storage device and related control hardware operating in conjunction with a pipeline graphics display system to reduce or eliminate the redundant matrix transformation of shared vertex data, thereby reducing the processing time required to generate the graphics images displayed for out-the-window simulation.
