20100158666 | OPPOSED FLOW HIGH PRESSURE-LOW PRESSURE STEAM TURBINE - An opposed flow high pressure-low pressure steam turbine balances thrust of the high pressure steam turbine with the thrust of the low pressure steam turbine allowing a reduction in size of thrust bearings. Higher stage reactions in both turbines may be incorporated since they are offset with the opposed flow, allowing a higher steam path efficiency. Opposed flow may be established through a cross-over pipe or utilizing a double high pressure shell. | 06-24-2010 |

20130022449 | Radial-Flow Turbomachines Having Performance-Enhancing Features - A turbomachine that includes a radial-flow impeller and one or more of a variety of features that enhance the performance of machinery in which the turbomachine is used. For example, when the turbomachine is used in a dynamometer, the features enhance the useful shaft horsepower range of the dynamometer. One of the features is a variable-restriction intake that allows for adjusting flow rate to the impeller. Other features include a unique impeller shroud and a shroud guide each movable relative to the impeller. Yet another feature is an exhaust diffuser that facilitates an increase in the range of shaft power and the reduction of deleterious vibration and noise. The turbomachine can also include a unique impeller blade configuration that cooperates with the adjustable intake and the exhaust diffuser to enhance flow through the turbomachine. | 01-24-2013 |

20100158667 | CENTRIPETAL PUMPING STAGE AND VACUUM PUMP INCORPORATING SUCH PUMPING STAGE - A molecular spiral-type vacuum pumping stage comprises a rotor disk having smooth surfaces cooperating with a stator. The stator is provided with a plurality of spiral channels at least on the surface facing the rotor disk, wherein the gas to be pumped flows in centripetal direction. The cross-section area (σ) of the channels is reduced from the center towards the outer periphery of the stator. Due to this arrangement, it is possible to avoid the reduction of the internal gas flow velocity along the pumping stage and the related risk of internal compression or re-expansions, this limiting the power losses. The present invention also refers to a vacuum pump comprising at least one pumping stage as described above. | 06-24-2010 |
