20120148386 | Turbocharger With Divided Turbine Housing and Annular Rotary Bypass Valve for the Turbine - A turbocharger includes a turbine wheel mounted within a turbine housing and connected to a compressor wheel by a shaft. The turbine housing defines an exhaust gas inlet connected to a divided volute that surrounds the turbine wheel, and an axial bore through which exhaust gas that has passed through the turbine wheel is discharged from the turbine housing. The turbine housing further defines a pair of concentric annular bypass passages surrounding the bore and arranged to allow exhaust gas to bypass the turbine wheel as two separate bypass streams. An annular bypass valve is disposed in the bypass passage. The bypass valve comprises a fixed annular valve seat and a rotary annular valve member arranged coaxially with the valve seat. The valve member is disposed against the valve seat and is rotatable about the axis for selectively varying a degree of alignment between respective orifices in the valve seat and valve member. | 06-14-2012 |
20130247560 | Turbocharger Cartridge and Engine Cylinder Head Assembly - An turbocharger cartridge and engine cylinder head assembly includes a turbocharger cartridge that includes some but not all of the components of a turbocharger, while the engine cylinder head provides the components of the turbocharger that are not included in the cartridge. The cartridge includes a center housing rotating assembly having a shaft that joins a turbine wheel to a compressor wheel, the shaft passing through bearings housed in the center housing. The engine cylinder head defines a receptacle that receives the cartridge. The head also defines a diffuser and volute for the compressor, and a turbine volute. The cartridge defines a turbine nozzle and turbine contour, and further includes a wastegate unit as a part of the cartridge. | 09-26-2013 |

20120066760 | ACCESS CONTROL IN A VIRTUAL SYSTEM - A method comprises determining a set of one or more authorizations associated with a role of a user responsive to the user entering a command with a parameter, wherein the command with the parameter is to be implemented via a first virtual partition that is configured to control access to a plurality of virtual input/output (I/O) devices by a plurality of other virtual partitions. The first virtual partition and the plurality of other virtual partitions are instantiated on a same system. The method includes determining that the role is authorized to execute the command based on the set of one or more authorizations. The method also includes determining that the role is authorized to execute the command with the parameter responsive to determining that the role is authorized to perform the command. The method includes executing the command with the parameter via the virtual partition. | 03-15-2012 |
