摘要： A packing ring assembly for use between a rotating and a stationary component in a turbomachine is disclosed, the assembly including an arcuate packing ring casing, an arcuate packing ring segment positioned at least partially within the packing ring casing, and a resistance component configured to allow movement of the packing ring segment in an axial direction, relative to the rotating component, between a first and second position in response to a pressure condition. In one embodiment, the resistance component allows movement when the pressure condition comprises approximately 30% of the turbomachine load. Also disclosed is an altered surface topography of the rotating component to accommodate variable length teeth extending from the packing ring segment, such that when the packing ring segment is in the first position, a clearance between the packing ring segment and the rotating component is larger than when the packing ring segment is in the second position.

摘要： A computer readable storage medium includes executable instructions to provide a scripting language framework. A script is run within the scripting language framework. The script defines an application characterized by a hierarchy of frames in a user interface window. A sub-frame log for a sub-frame in the hierarchy of frames is captured. The log is stored in a top log of a top frame of the hierarchy of frames.
