Abstract: A gas turbine engine component has an axial seal pin assembly for sealing between adjacent platform regions where the seal pin assembly design provides a seal pin damper slot extending to a forward axial stop in a forward buttress region. The forward axial stop includes a relief slot to interrupt the loadpath from the airfoil into the blade neck and attachment regions to reduce the stress concentrations in these regions.

Abstract: A system for storing and deploying fire hoses to combat a fire on a selected floor of a high-rise building. The system includes an underground storage area directly beneath the building, a plurality of reel assemblies located inside the storage area, an underground pump, an integrated piping network, a plurality of mechanical tracks and a station located on the roof that has a pair of roof standpipes extending therefrom. Each reel assembly has a reel, a fire hose and an underground standpipe. Each track extends vertically along side walls of the building. In use, an operator uses an electronic control panel in communication with the reels and the rollers to specify the floor of the fire. The hoses unravel from their reels and are propelled up the tracks by rotating rollers. The pump turns on and transports water from an independent source, through the piping network and to the hoses.
