A method and apparatus for balancing the rotor in the low pressure stage of the turbine in a jet engine comprises attaching at least one balance clip to the shroud of the rotor. The balance clip comprises a clip body formed with a forward hook portion adapted to extend over the forward rail of the shroud and an aft tab which is crimped over the aft rail of the shroud onto its outer surface so that the clip body is retained against the interior face or diameter of the shroud. The balance clip is formed of sheet material such as AMS 5596E/5597B whose weight can be varied by altering the thickness or width of the clip body, or by drilling holes in the clip body to remove material therefrom.

A method of securing an workpiece for machining the trailing edge. The workpiece has a platform from which extends an airfoil, the airfoil including a leading edge and a trailing edge, and a pressure side and a suction side. A fixture with at least one locating datum that relates to the platform and at least one locating datum that relates to the leading edge is provided. The fixture does not contact the trailing edge of the workpiece. The workpiece is positioned so that the platform is against the related locating datum and the leading edge is against the related locating datum. The workpiece is secured within the fixture, and the trailing edge of the workpiece is machined.

A power regulation scheme includes a first voltage regulation portion having a first voltage regulator, a second voltage regulator, and a switching system. The first voltage regulation portion is connected in parallel with a second voltage regulation portion. The second voltage regulation portion regulates an input voltage if an open condition occurs within the first voltage regulation portion. The switching system forces the second voltage regulator to regulate the input voltage if a short condition occurs within the first voltage regulator.

The invention relates to novel cytotoxic agents comprising taxanes and their therapeutic use as a result of delivering the taxanes to a specific cell population in a targeted fashion by chemically linking the taxane to a cell binding agent.
摘要:
A method for coating a nozzle segment, the method comprising separating an outer shroud and an inner platform of the nozzle segment along pathways that bisect a first stator vane and a second stator vane of the of the nozzle segment, coating the first stator vane and the second stator vane after separating the outer shroud and the inner platform, and rejoining the separated outer shroud and the separated inner platform after coating the first stator vane and the second stator vane.
摘要:
A system and method for automatically determining a physical location of one or more units in a rack, including: using one or more physical cables between rack units; cascading a first signal through the one or more units located in the rack, the first signal being encoded with a unit number and a physical parameter; and creating a rack ID by utilizing hardware parameters, the hardware parameters being determined by: detecting a second signal that exists from a bottom unit, the bottom unit located at the bottom of the rack; and using a third signal to send data between the one or more units in the rack by manipulating void spaces within the rack, the third signal being either cabled or an optical signal.
