Abstract: A mixed rope used for oceanographic buoy mooring system, comprises mixed core rope of metal and fiber and cover rope, wherein, the mixed core rope of metal and fiber comprises metal coil spring and fiber supporting core inside the metal coil spring; the cover rope is woven of several number of twisted strand; the mass content of the mixed core rope of metal and fiber is not greater than 20% of the mass of mixed rope, the mass content of the cover rope is not less than 80% of the mass of the mixed rope. Mixed rope used for oceanographic mooring system disclosed in present embodiments has small linear density and high fracture strength, may be used as data communication channel from under-water sensor to the over-water receiver, being soft, light and easy to deploy, the mixed rope can be used as the upper part of the oceanographic buoy mooring system with prospective application.

Abstract: The present disclosure relates to a turbomachine that includes a first component and a second component coupled to another and a seal assembly between the two components. The seal assembly may include a first intersegment seal, a second intersegment seal, and a rope seal that are configured to block a flow of gas between the two components.

Abstract: A compressible sealing ring assembly seals an annulus between a radially outer member and a radially inner member. The sealing ring comprises one or more sealing ring members (28), a radially outer wall for sealing with the inner wall of the radially outer member and radially inner wall for sealing with the outer wall of the radially inner member. A compression ring member (10) having a concave lower surface and a convex upper surface exerts an axial force on a sealing ring member to deform the sealing ring member to maintain a seal.

Abstract: A gland packing which is made of a material configured by windingly laminating an expanded graphite tape into a spiral shape. In the gland packing, ring-like projected parts are disposed on end faces of a die mold packing part made of an expanded graphite tape windingly laminated into a spiral shape so as to be integrated with the part. Ring-like seal members are brought into tight contact with the end faces of the die mold packing part excluding the ring-like projected parts in such a manner that the ring-like projected parts are projected in an axial direction beyond the outer faces of the respective ring-like seal members.

Abstract: A method of manufacturing a leaf seal for use between rotating components comprises forming corrugations within a metallic strip and feeding the corrugated strip into a seal guide. The corrugated strip is then pressed into the guide by an angled ram such that the corrugations lie at an acute angle to the perpendicular axis. The strip is then secured in a seal carrier, the free ends of the corrugations thus forming the angled sealing leaves of a leaf seal.

Abstract: The present invention relates to a gland packing which is made of a material configured by laminating an expanded graphite tape into a spiral shape by winding. The gland packing can prevent penetration leakage through minute gaps existing in the laminated parts, from occurring, can be sufficiently deformed so as to exhibit sure sealing properties even at a low tightening force, and has properties which result in a small amount of wear so as to ensure high sealing properties, so that high sealing performance can be maintained for a long term. In the gland packing, circumferentially projected parts are disposed on end faces of a die mold packing part made of an expanded graphite tape laminated into a spiral shape so as to be integrated with the part.

Abstract: A split sealing member for a rotary shaft comprising a coiled body, with non-adjoined ends, having a plurality of turns about a central axis, bent along the course of the body such that the body is divided into a radially-inner portion and a radially-outer portion wherein the radially-inner portion defines a first plane and the radially-outer portion defines a second plane which is substantially transverse to the central axis.

Abstract: A resilient braided rope seal for use in high temperature applications includes a center core of fibers, a resilient canted spring member supporting the core and at least one layer of braided sheath fibers tightly packed together overlying the spring member. The seal provides both improved load bearing and resiliency. Permanent set and hysteresis are greatly reduced.
