Abstract: A process of forming a turbine engine seal includes the steps of: providing a flat strip of material; roll forming the flat strip of material forming an asymmetric profile in the flat strip of material; coiling the formed asymmetric profile into an overlapping ring shape; cutting the circular shape to a predetermined length; and joining ends of the predetermined length forming the seal. The seal includes at least two peaks that are formed on opposing sides of a gap. The at least two peaks contact opposing sides of a U shaped profile at a zero radius. The asymmetric profile includes a circular shape and the ends are joined.

Abstract: A sliding window assembly for a vehicle includes a window frame having a top rail portion coupled to a bottom rail portion by side rail portions. The top rail portion has a shorter length than the bottom rail portion. A fixed window is attached to the window. A sliding window is mounted in a sliding sash. The sliding sash is moveable relative to the fixed window. The sliding sash includes a top sash portion coupled to a bottom sash portion by side sash portions. The top sash portion has a shorter length than the bottom sash portion. A removable track assembly is attached to the top rail portion. At least one bearing is attached to the top sash portion of the sliding window sash. The at least one bearing is slidingly engaged with the removable track supporting the sliding sash over an entire travel range between open and closed positions preventing tilting of the sliding sash relative to the window frame.
