A sealing arrangement at an interface between a combustor and a turbine of a gas turbine. The turbine can include deflecting vanes at its inlet, which deflecting vanes are each mounted within the turbine so as to define an inner or outer diameter platform and are in sealing engagement via an inner or outer diameter vane tooth with a seal arranged at the corresponding inner or outer diameter part of the outlet of the combustor. The seal is movable and is pressed on the inner or outer diameter vane tooth by a differential pressure such that the pressure of the mainstream hot gas flow is a lower pressure.

A seal assembly and methods of use, wherein the seal assembly is formed of an elastomeric enclosure within which a primary cavity is defined. A second cavity in the form of a crushable container is deployed within the primary chamber. An elastomeric compound is contained in one cavity and an elastomeric hardener contained in the other cavity. Upon application of an external force to the elastomeric enclosure, the enclosure is elastically deformed from a first shape to a second shape, wherein the second shape positions the elastomeric enclosure into a sealing configuration between adjacent annular surfaces. The external force also crushes the container, to cause mixing of the elastomeric compound and elastomeric hardener. Once the reaction is complete, the hardened compound retains the deformed shape of the elastomeric enclosure to maintain a seal between the annular surfaces.

A seal for sealing between an inner member and an outer member includes an annular seal body formed of an elastomeric material, disposed on one of the inner and outer members having an annular groove and has first and second circumferential surfaces. An annular actuator lug extends radially from the body second circumferential surface and is disposed within the annular groove. An annular sealing bead extends radially from the body first circumferential surface and circumferentially about or within the lug. An activation surface section of the first circumferential surface is defined adjacent to the sealing bead and extends circumferentially about or within a portion of the lug. The lug is configured to bias the sealing bead radially toward the circumferential surface of the other one of the inner and outer members when fluid pressure is exerted on the activation surface section.

The telescoping joints (110,114) of an articulating aircraft passenger boarding bridge are sealed airtight by an expandable seal (202) in the overlapping and concentric portion between the outer circumference of an internal structure (106) and the interior circumference of an external structure (108). The preferred embodiment is an inflatable bladder (202) with an air outlet (412) and an air inlet (406) to accept compressed air. The bladder (202) expands to seal the gap between the concentric structures when the telescoping structures are immobilized and deflate to allow movement of the telescoping structures. The embodiment may be comprised of a plurality of expandable seals geometrically shaped to form a whole seal.

A locomotive sanding system is described for conveying sand from a sand tower to a sand box mounted on a locomotive. The invention is designed to prevent personnel from being subjected to sand and sand dust during the sand box being filled with sand from the sand tower. The system includes a universal sealing nozzle which may be used with the locomotive sanding system or other devices. The universal sealing nozzle includes an expansion seal extending therearound which may be moved from a retracted position to an expanded position. When the nozzle is inserted into the fill pipe of the sand box, the expansion seal is expanded to sealably engage the inside surface of the fill pipe.
