20100303627	TURBINE STAGE - A turbine stage includes a circumferentially distributed row of adjacent airfoils between which there is a flow passage. The passage has a surface, which in its unmodified form, defines a datum plane. A channel, located in the passage, extends in the direction of an airfoil pressure face from a point towards a leading edge line to a point towards a trailing edge line. The channel includes two channel walls angled relative to the datum plane. Relative to the datum plane, the channel has a low point, two high points, and a channel height, which is measured between the low point and the highest one of the high points. The channel provides a means to reduce secondary flow losses.	12-02-2010

20100221095	STEAM TURBINE AND METHOD FOR EXTRACTING MOISTURE FROM A STEAM TURBINE - A steam turbine is disclosed which includes a casing containing a plurality of expansion stages, each including stator and rotor airfoils. Downstream of the stator airfoils of one or more expansion stages, the casing includes a slot arranged to receive moisture that concentrates on an end wall of the stator airfoils and discharge it to the outside. Each end wall has a side portion facing the slot having a variable radial obstruction in a tangential direction, in order to define with the slot a passage through which the moisture may pass that is smaller or closed at the suction side and larger at the pressure side of the stator blades, to at least partially prevent the dry steam from entering the slot at the suction side of the blade.	09-02-2010

20110146437	Gearing - A gearing having a shaft that projects from the gear interior into the environment, the shaft being sealed with the aid of at least one contactless seal, and the opening of the contactless seal, which is oriented toward the interior of the gearing, i.e., the spatial region of the gearing that contains the lubricating oil, being disposed above the lubricating oil level that comes about when the gearing is not in operation, a tin piece being disposed between the opening and the gear-tooth piece situated closest to this opening and generating lubricating oil waves and/or lubricating oil foam from the lubricating oil bath.	06-23-2011
