摘要:
A cap (100) for sealing pressure vessels is disclosed. The present invention permits a nominal closure to be formed by hand tightening and a substantially higher force to be applied to a cap by a separate clamp mechanism, thereby forming a pressure seal. In certain preferred embodiments, means for providing a process flow through a hole (120) in the seal and filtering means (130) are also provided as part of the cap assembly. A preferred application of the cap of the present invention is for the sealing of sample vessels used for supercritical fluid extraction of compounds from a solid matrix for subsequent chemical analysis. Methods of supercritical fluid extraction are also disclosed. The present invention thus provides methods and apparatus whereby the placement of a sample into a pressurized system may be automated and monitored to ensure adequate seals have been created and maintained within such pressurized systems.

Die Dichtung (104) ist insbesondere für den Einbau zwischen einem Magnetkopf und einer Gerätesteckdose (105) vorgesehen, wobei elektrische Stecker (103) die Dichtung (104) durchsetzen. Die Flachdichtung (104) weist einen aus einer elastischen Dichtungsmasse vorgeformten Schnapp- oder Klapprahmen (126,127) auf, in dem eine mit elektrischen Bauteilen (112) versehene Leiterplatte (108) gelagert ist.
摘要:
In a gas turbine in which a seal member 6 seals a gap between a transition piece 16 and a nozzle end wall 17 in a turbine first stage, the transition piece 16 and the nozzle end wall 17 has a seal groove 21. The seal member 6 includes a hook portion 7 that slides in the turbine radial direction with respect to the flange 19 and a seal plate portion 8 inserted in the groove 21. The groove 21 and the portion 8 are configured to include a surface contact region 31 in which a surface 21a of the groove 21 and the portion 8 are in surface contact with each other, a noncontact region 32 disposed on a side closer to the transition piece 16 than the region 31, and a hole 23 provided at the portion 8 so as to face the surface 21a in the groove 21 across a gap in the region 32.
摘要:
The present invention relates to a cosmetic container comprising a refill container having a sealing ring and, more specifically, to a cosmetic container comprising a refill container having a sealing ring, the cosmetic container having a refill container holder embedded in an outer case, and having the refill container, which contains cosmetics, used by being coupled to the refill container holder, and improving refill convenience since after the cosmetics are completely used, a user easily separates the refill container from the refill container holder by pressing the refill container on the top thereof, and then can couple a new refill container to the refill container holder from the bottom of the outer case, thereby easily replacing the refill container.
摘要:
A seal ring (14) for sealing a container (12). The seal ring has a base (30) and a longitudinal axis (B) extending therethrough, a radially outer portion (32), and an inner seal (36). The radially outer portion has a locking band (34) that is configured to lock beneath an external engagement element (28) of a container (12) so as to secure the seal ring thereto. The inner seal is configured to be biased into sealing engagement with an inner finish surface (29) of the container. The seal ring may be part of a package (10) that also includes the container having a finish (22) that comprises a sealing lip (26), the external engagement element (28), and an inner surface (29), and a foil (16) sealingly and removably coupled to the base of the seal ring.
