摘要:
A seal ring (14) for sealing a container (12). The seal ring has a base (32) including a longitudinal axis (B) extending therethrough and having a top surface (38), an undersurface (40) opposite the top surface, and a projection (42) extending from the undersurface in an axial direction. The projection is configured to be received by a complementary opening (28) in the container. The seal ring may be part of a package (10) that also includes a container (12) having a mouth (24), an axially-facing sealing surface (26), and an opening (28) in the sealing surface, and a foil (16) sealingly and removably coupled to the base of the seal ring.
摘要:
A system and method for detecting, marking and/or sealing building envelope leaks in buildings or any enclosed structure. Fogs of aerosolized sealant particles that have a surface tackiness that diminishes over time are introduced into the interior of prepared rooms. The surface properties of the aerosol particles can be controlled with the selection of sealant composition, including the presence and concentration of solvents, the range of produced particle sizes, and the relative humidity and temperature within the enclosure. A pressure differential is created and the micron scale particles adhere to the leak edges and to other particles as they are brought to the leaks and then leave the gas streamlines. Control of particle size, drying rate and particle residence time in the building interior allows control over the treatment area so that leaks are sealed without leaving a tacky residue.

The present application and the resultant patent provide improved gas turbine component sealing. In one example embodiment, a gas turbine segment seal assembly 100 may include a first tapered segment seal 120 with a first tapered portion 140 having a first tapered surface and a first taper angle 142. The gas turbine segment seal assembly may include a second tapered segment seal 150 with a second tapered portion 170 having a second tapered surface and a second taper angle 172. The gas turbine segment seal assembly may include a seal pin 180 positioned in between the first tapered segment seal and the second segment seal and adjacent to the first tapered surface and the second tapered surface.
