Provided is an annular gasket for sealing a gap between opposed surfaces of two members, the gasket including a core body including a plurality of split components, a sealing unit fixed to the core body, and an elastic member, in which: ends of the plurality of split components are mated together in such a manner as to have a gap between the ends; the ends mated together are joined by the elastic member; and edges of the joined ends are inclined relative to a longitudinal direction of the split components in plan view.

A thermal processing apparatus (20) includes a spiral conveyor system (22) configured into an ascending spiral stack (26). An inner mezzanine (40) is disposed within the circular interior of the stack (26) and an exterior mezzanine (42) encircles the spiral stack. The mezzanines divide the processing chamber (32) into a plurality of processing zones. A sealing system (90) seals the interior mezzanine (40) relative to the spiral stack (26). A sealing system (130) seals the outer mezzanine (42) relative to the exterior of the spiral stack, and a seal system (132) seals the outer mezzanine relative to the walls (56, 58) of the housing, thereby to limit the leakage of the processing fluid between the mezzanines and the spiral stack (26) and housing walls so that as much as the thermal processing medium is possible is forced through the spiral stack for processing work products carried on the conveyor system (22).

A back-up ring (1) for a gland seal includes at least two part ring portions (2,4). Each part ring portion comprises first (6, 10) and second (8, 12) ends. Each end has an undulating surface (22, 24) for overlapping in engagement with a corresponding undulating surface on an end of another part ring portion, to form the back-up ring (1). When the part ring portions (2,4) are assembled to form the back-up ring (1) and are held together by axial and/or radial compression, the engagement of the undulating surfaces (22, 24) restricts relative movement between the part ring portions. A seal assembly (34) including the back-up ring (1) is also disclosed.

A sealing assembly and a turbomachine including the sealing assembly are provided. The sealing assembly includes a sealing body configured to be inserted into an insertion hole of a second component adjacent to a first component, and a sealing protrusion, formed on one circumferential side of the sealing body, protruding toward one circumferential direction from the sealing body and configured to be inserted into a sealing groove formed on the other circumferential side of a sealing body of the first adjacent sealing assembly, the sealing body of the first adjacent sealing assembly being adjacent to the sealing body in a circumferential direction.

A plate heat exchanger comprising a top head, a bottom head, four side panels and four corner girders. The side panels and the corner girders extend along a longitudinal direction from the bottom head to the top head, and each side panel is associated with two corner girders. The top head, the bottom head, the four side panels and the four corner girders are joined together to form a sealed enclosure for housing a plate pack of stacked heat-exchanging plates. A continuous gasket assembly is arranged in a contact region between at least one side panel and two corner girders, the top head and the bottom head. The gasket assembly is located in a groove. Moreover, the gasket assembly is a segmented gasket assembly composed of plural gasket segments, and each gasket segment is made of graphite material. Also disclosed is a method for assembling such a plate heat exchanger.

In order to provide a seal arrangement, in particular for sealing a first fluid space from a second fluid space or a plurality of fluid spaces, which on the one hand can be produced in a simple and cost-effective manner and also allows reliable sealing of a first fluid space from a second fluid space, it is proposed that the seal arrangement comprises the following: A sealing element for arrangement between a first object and a second object, the sealing element comprising two or more sealing element components which can be or are connected directly or indirectly to one another and which each comprise a base body part and a resilient sealing body part arranged on the base body part, the base body parts of the sealing element components preferably forming a dimensionally stable base body of the sealing element, and the resilient sealing body parts of the sealing element components forming a resilient sealing body for providing a sealing function of the sealing element.

The present disclosure relates to a seal for sealing an inner chamber of a housing from an exterior of the housing, comprising at least one sealing layer that has: at least two rigid sealing layer portions having a respective support element, wherein the rigid sealing layer portions are interconnected by a flexible sealing layer portion, which consists of or comprises at least in part an elastomer; and at least one sealing contour, which extends continuously over the different sealing layer portions, wherein the support elements each comprise, in an end region adjoining the flexible sealing layer portion, at least one through-opening, through which the elastomer of the flexible sealing layer portion extends, and the end region of each support element is coined in at least one first end-side coining region and is enclosed by the elastomer in the first end-side coining region at least in some regions.

A seal assembly for a gas turbine engine includes first and second split-ring seals. The first split-ring seal includes circumferentially separated first and second ends, laterally separated first and second edges, a first sealing lobe adjacent the first edge, and a first integral clip portion adjacent the second edge. The first sealing lobe has a curved surface extending laterally outward from the first edge. The second split-ring seal is slidably received and nested in the first seal. The second split-ring seal includes circumferentially separated third and fourth ends and laterally separated third and fourth edges.

A seal for a gas turbine engine may include a first cartridge, a second cartridge, and a wave spring. The wave spring may be located between the first cartridge and the second cartridge. The first cartridge may contact a first component to form a seal. The second cartridge may contact a second component to form a seal. The first cartridge may contact the second cartridge to form a seal. The wave spring may force the first cartridge to contact the first component, and the wave spring may force the second cartridge to contact the second component.

A sealing unit used to block liquid comprises a sealing block, a receiving hole, a wire-through hole, and a sealing piece. The receiving hole penetrates the sealing block. The sealing piece is received in the receiving hole. A surface of the sealing block is in contact with the receiving hole. A material of the sealing piece is elastic material. The sealing piece is penetrated by the wire-through hole and forms an open penetrating structure. The present disclosure also provides a wireless intercom device using the sealing unit.
