  • Patent number: 6402459
    Abstract: The invention relates to a device (1), including an elongated tubular body (3) arranged to be located in water in an essentially vertical position. The tubular body (3) includes an open end (6) at the bottom and a narrowing portion (7) at the top, which ends in an opening (8) arranged to be located above the level of the surrounding water (2). The device (1) is arranged to establish a water level in the narrowing portion (7) of the tubular body (3), which is lower than the level of the surrounding water and to intermittently level out this level difference in such a way that the water in the tubular body (3) is transported up to a higher level than the level of the surrounding water by the action thereon of the narrowing portion (7).

  • Patent number: 6382908
    Abstract: A nozzle vane includes a row of trailing edge apertures and cooperating inboard slots joined in flow communication with a mid-chord cavity. An outboard slot is spaced outwardly from a respective last one of the inboard slots, and outboard of a respective last one of the trailing edge apertures. The outboard slot extends behind a fillet between the vane and a supporting band and is effective for backside cooling thereof.

  • Patent number: 6375410
    Abstract: A frangible cover is provided for a recess in a containment case for turbofan engine blade removal and access. The recess provided in the containment case allows outward radial movement of the engine fan blade when the engine fan blade is to be removed from the containment case. The present invention proposes a frangible component to cover the recess. A plurality of initiation points, notched in the frangible cover at intersections of surfaces encourages brittle fracture of the frangible component.

  • Patent number: 6354795
    Abstract: A cooling shroud segment for a high pressure turbine that provides improved cooling in the region of the side panels from the midsection thereof forward to the leading edge and particularly in the midsection of the side panel. A shroud subassembly can be formed from a pair of such adjacent shroud segments with opposed adjacent side panels where the spacing of the outlets of the cooling air passages exiting from each of these adjacent side panels are staggered and where the adjacent panels have a spline seal slot with a humped section in at least the midsection of the side panel above and across the outlets of the cooling air passages exiting from the midsection of the side panel, in combination with a spline seal positioned in the gap between the opposed adjacent side panels. This shroud subassembly provides more uniform impingement cooling coverage and localizes more of the cooling air exiting the outlets from these passages in the midsection of the opposed side panels.
