F01D 904

US Classification:

415189, 415119, 4152093, 4152094

Abstract:

A stator assembly for a rotary machine having a shroud for a stator vane is disclosed. Various construction details are developed which limit movement of the stator vane into the flowpath by reason of the stator vane being restrained by the shroud. In one particular embodiment, a clip member extends through an opening in the tip of the vane and is disposed at a location adjacent a nonflowpath surface of the shroud to restrain the tip of the vane against inward movement through the shroud.

Abstract:

A hand-warmer assembly and method of using the same. According to one embodiment, the hand-warmer assembly includes a hand-warmer and a leash connector. The hand-warmer may include a sleeve or a mitt having an open end for receiving a user's hand and a closed end. A pocket for holding personal effects may be provided on the exterior of the hand-warmer. A closure mechanism, such as a drawstring, may be provided to close the open end around the user's wrist or arm. The leash connector may include a strap and a clasp. The strap passes through the closed end of the hand-warmer, with a first end external to the hand-warmer and a second end within the hand-warmer. The first end of the strap is coupled to the clasp, which may be secured to a pet collar or leash. The second end of the strap forms at least one loop.
