A composite torque pipe to metal fitting joint including concentric inner and outer shells formed with respective smooth annular surfaces projecting distally to form an annulus of a predetermined configuration for receipt of a composite connector ring of the predetermined configuration.

A mounting head (T) for mounting a pump or a valve on a neck (22) of a reservoir (2), the mounting head (T) having a mounting member (3) for imparting an axial mounting movement from an axial arrangement placed on the neck (22). The mounting member (3) has a centering mechanism (35, 36, 4) bringing the dispenser member (1) into an axial arrangement on the neck (22) if offset. The mounting head (3) has mounting tabs (31) movable axially so as to bring the dispenser member (1) from the axial arrangement towards the final position, and movable radially inwards so as to return the dispenser member (1) into an axial arrangement. An outer clamping collar (4) simultaneously moves the mounting tabs (31) radially inwards from a spaced-apart rest position.

The present invention is for sealing gaskets applicable to pipes, valves and boiler equipment. In this context, the present invention provides a sealing gasket for piping systems comprising (i) a core (10) formed by a plurality of concentric metal rings (10a), each ring (10a) comprising a substantially rectangular cross-section, wherein the height of the rectangular cross-section is the same for all the rings (10a), and (ii) surface coating (12) of flexible material applied to the upper and lower surfaces of the core (10). The present invention also provides the manufacturing process of said sealing gasket. Thus, the present invention provides a sealing gasket (i) that eliminates the need for an external rigid ring, (ii) that is easy to conform for reduced-diameter sealing gaskets and (iii) can be easily formed into different shapes, such as an oval shape, which is particularly useful for sealing between the body and the gate valve bonnet.

A closure assembly includes a section of duct, a duct coupler assembly, a closure load plug, and an end cap. The duct coupler assembly is fit against the section of duct. The closure load plug is mechanically connected to the duct coupler assembly. The end cap is mechanically connected to the closure load plug.

An aseptic coupling device for a tube, the device comprising: a tubular insert defining a channel and having an end segment provided with means for connecting it to the tube, the tubular insert being provided with a cantilevered rod extending axially inside the channel; and an annular body having an end segment mounted on the insert and co-operating therewith to define a housing for receiving an annular sealing element that is deformable from a first state in which it defines a flow section greater than the cross section of the rod and a second state in which it tightly surrounds the rod, and that is arranged to be taken from its first state to its second state under the effect of axial compression exerted by the insert.

A coupling assembly for coupling two tubes together.

A method for installing pipeline segments within a conduit. The method includes a step of securing a first pipe segment of the pipeline segments at a top end of the conduit, a step of aligning a main axis of a second pipe segment of the pipeline segments with the main axis of the pipeline, a step of lifting the second pipe segment from a first position associated with a bottom end of the conduit to a second position adjacent to the first pipe segment, a step of abutting a top rim of the second pipe segment against a bottom rim of the first pipe segment, and a step of attaching the top rim of the second pipe segment to the bottom rim of the first pipe segment.

A turbine shroud for incorporation in a turbine of a gas turbine engine has a plurality of butted shroud segments circumferentially arrayed to form a ring. Each of the shroud segments has an arcuate main shroud body portion, a radially inward extending annular flange attached to a first end of the main body portion, and a radially outward extending flange with a plurality of mounting apertures attached to a second end of the main shroud body portion. A first mounting aperture is sized smaller than an adjacent second mounting aperture in the radially outward extending flange.

A plug unit for connecting capillary tubes includes a plug housing that has an axial borehole, a plug capillary tube that projects through the axial borehole, and a sealing element that surrounds the plug capillary tube. The front end of the plug capillary tube is sealed by an elastic and/or plastic deformation of the sealing element against the capillary tube receptacle opening of a bushing unit. A hollow cylindrical pressure piece is provided that surrounds the sealing element in an axial region facing away from the end surface of the plug capillary tube, and the pressure piece has a rearward end side that faces away from the end surface of the plug capillary tube and that can be loaded by the plug housing with an axial pressure force when the plug unit and bushing unit are connected.

Methods and systems for metal-to-metal sealing and, in particular, to the use of sintered parts to create metal-to-metal sealing joints is disclosed. In one example, a metal-to-metal sealing joint may comprise: a first mating surface and a second mating surface; wherein the first mating surface is formed on a first assembly having an annular projection with one or more annular grooves and the second mating surface is formed on a second assembly; wherein the projection is configured such that when the first and second surfaces are brought into mating contact, the annular projection on the first mating surface deforms the second mating surface to form a sealing joint. In this way, the metal-to-metal sealing joint between the first and second mating surfaces may minimize oil leakage between two assemblies, thereby improving engine fuel economy while simplifying part manufacturing.

A metal to composite tube joint including selecting an elongated interior fitting constructed with an exterior barrel, reduced in exterior diameter to form a distally facing annular shoulder and then projecting still further distally to form an interior sleeve having a radially outwardly facing bonding surface. A metal outer sleeve formed proximally with a collar constructed for receipt over the barrel and increased in interior diameter and projecting distally to form an exterior sleeve having a radially inwardly facing bonding surface cooperating with the first bonding surface to form an annulus receiving an extremity of a composite tube and a bond bonding the extremity of the tube to the bonding surfaces.
