The invention is characterized in that the stationary component provides for each vane a radially orientated through-hole designed and arranged for a radial insertion and removal of the vane, and each of said vanes comprises an airfoil having at its one end directed radially outwards a contour being adapted to close the through-hole airtight by a detachable fixation means. | 2014-01-30 |
20140030078 | STATOR AND METHOD OF MANUFACTURING STATOR - In a stator, segment coils each consisting of a pair of straight portions connected with a connecting portion in a U-like shape are set in slots of a stator core. Each straight portion has distal end parts protruding on an opposite side to the connecting portions. The distal end parts in odd-numbered positions from an outer or inner circumferential side in a radial direction are twisted in one direction and shaped radially outward and the distal end parts located in even-numbered positions are twisted in an opposite direction to the one direction and shaped radially inward to be joined to each other on the same circumference by welding. | 2014-01-30 |
20140030079 | LOCKING DEVICE WITH MECHANICAL DETECTION OF CLOSURE AND OPENING - A locking device between a first structure and a second structure includes a bolt to lock the first and second structures, an indicator as to whether the bolt has locked/unlocked the structures, and a connecting system. The bolt includes a lock bolt attached to the first structure and able to engage a hook which is attached to the second structure. In particular, the connecting system connects the bolt with the lock bolt to the indicator, and the hook is mounted such that it can move between a first position in which it is engaged with the lock bolt and allows the indicator to be locked, and a second position in which the hook is free of the lock bolt and allows the indicator to be unlocked. | 2014-01-30 |
20140030080 | TURBINE HOUSING FOR AIR CYCLE MACHINE - A turbine inlet housing has a main housing body extending about a central axis. An inlet duct delivers air into a cavity within the main housing body. Bolt hole bosses are formed on a downstream face of the inlet housing to receive bolts to secure an outlet housing to the inlet housing. A plurality of the bosses have a ramped surface which extends radially outwardly for a greater extent than a second plurality of bosses. The plurality of ramped bosses extend between the downstream face and the duct. The ramped bosses have a forward boss portion, and a ramped surface at an angle of between 50 and 54 degrees extending from an upstream end of the forward boss portion. A curved surface curves from an upstream end of the ramped surface to merge into the duct. A turbine stage and air cycle machine are also disclosed and claimed. | 2014-01-30 |
20140030081 | ADJUSTABLE CENTRIFUGAL GOVERNOR SPEED CONTROL - A rotational speed governor for an air motor comprises a housing, a valve, a shaft, a cross-bar, a plate and a pair of weights. The housing has an air inlet and an air outlet. The valve is disposed between the air inlet and the air outlet. The shaft extends along an axis within the housing. The cross-bar is connected to the shaft. The plate intersects the shaft between the valve and the crossbar. The weights are rotatably connected to the crossbar at pivot points. Each weight comprises an arcuately profiled edge extending beyond the crossbar to engage the plate. The arcuately profiled edges are shaped to increase a moment arm on the plate as the weights pivot away from the shaft. | 2014-01-30 |
