Vane platform rail configuration for reduced airfoil stress

Publication number: 20060013685

Abstract: A vane assembly for a gas turbine engine is disclosed having lower thermally induced stresses resulting in improved component durability. The stresses in the vane assembly airfoils are lowered by increasing the flexibility of the vane platform and reducing their resistance to thermal deflection. This is accomplished by placing an opening along the vane assembly rail that reduces the effective stiffness of the platform, thereby lowering the operating stresses in the airfoils of the vane assembly. A removable seal is then placed in the opening in order to prevent undesired leakages, while maintaining the benefit of the increased platform flexibility.

Facilitating management of resources by tracking connection usage of the resources

Publication number: 20050267958

Abstract: The amount of resources utilized by one or more connections of a communications environment is obtained. A determination is then made as to whether one or more of the connections is using a predominant amount of the resources. If a particular connection is using more of the resources than desired, then action is taken with respect to that connection.

Apparatus and methods for repairing tenons on turbine buckets

Publication number: 20050214124

Abstract: Bucket tip tenons requiring refurbishment are removed from the bucket tips by grinding. Groups of buckets are clamped on a rotatable table in positions adjacent an induction heating coil and a robotic welding arm, respectively. While one group is preheated, the other group of buckets is in a welding location, enabling the welding head on the robotic arm to sequentially apply weld buildup material to the bucket tips. After applying weld buildup material in multiple passes and sequentially to the bucket tips, the buckets are removed, stress-relieved and the weld buildup material machined to provide refurbished tenons. Upon removal of the buckets from the table, the table is rotated to locate the preheated buckets in welding locations and additional buckets are clamped to the table for preheating.

Methods for inducing T cell tolerance to a tissue or organ graft

Publication number: 20050152897

Abstract: Methods for inducing T cell tolerance to a tissue or organ graft in a transplant recipeint are disclosed. The methods involve administering to a subject: 1) an allogeneic or xenogeneic cell which expresses donor antigens and which has a ligand on the cell surface which interacts with a receptor on the surface of a recipient T cell which mediates contact-dependent helper effector function; and 2) an antagonist of the receptor which inhibits interaction of the ligand with the receptor. In a preferred embodiment, the allogeneic or xenogeneic cell is a B cell, preferably a resting B cell, and the molecule on the surface of the T cell which mediates contact-dependent helper effector function is gp39. A preferred gp39 antagonist is an anti-gp39 antibody. The allogeneic or xenogeneic cell and the gp39 antagonist are typically administered to a transplant recipient prior to transplantation of the tissue or organ.

Light with a clip

Publication number: 20050128738

Abstract: A portable light intended for mounting on a garment as support includes two LED light sources spaced apart towards the rear of the portable light. A clipped base below on anchor facilitates locating a garment between the anchor and the base, and a spring action urges the base toward the anchor. A hingedly movable head for the LEDs is mounted on the housing to move to and form the housing. An opening of the housing causes a switch in the housing to move between an opened and closed position such that a circuit actives or de activates the LED lights when the head opens or closes relative to the housing.

TURBINE SPRING CLIP SEAL

Publication number: 20050062237

Abstract: An improved turbine spring clip seal for directing gases to be mixed with fuel in a combustor basket. The turbine spring clip seal is composed of inner and outer housings and a center sealing member disposed between the inner and outer housings. The center sealing member is flexible and prevents a fluid, such as air, from leaking through the seal. In operation, the center sealing member flexes and is sealed against the outer housing by a pressure differential that is created by the relatively higher pressure on the inner housing side and the relatively lower pressure on the outer housing side.
