CAST-IN TUNNEL GASKET AND JOINING METHOD
A tunnel segment gasket and a method for making and using a tunnel segment gasket (1, 1) comprising a shaped profile (3, 3) having at least two anchoring legs (5, 5) for casting in to a tunnel segment (6, 6); a plurality of longitudinally extending bores (7, 7); a shot film joint (43) and a strengthening element (11, 4) at the base (9) of the gasket (1, 1).
Systems and methods for sealant injection molding
A mold tool is provided that includes plural mold sub-volumes configured to receive a sealant, a mold channel in fluid communication with the mold sub-volumes, a sealant injection port in fluid communication with the mold channel, vacuum application ports in fluid communication with the mold sub-volumes, and an air control system. The air control system is operably coupled to the mold sub-volumes and the mold channel, and is configured to apply a vacuum to the mold sub-volumes via the vacuum application ports.
Shaker Flask Stand with Composite Legs
A flask stand is configured to support a flask and includes a base ring and a plurality of legs. The base ring is configured to support a lower portion of the flask. Each leg is secured to the base ring and extends outward from the base ring. Each leg includes a body, a lattice, and an elastomeric foot. The body includes a first end portion that is secured to the base ring with the foot portion being opposite the first end portion. The lattice is formed within the foot portion and includes a plurality of members that form an open-mesh frame that defines a plurality of voids between adjacent members of the frame. The elastomeric foot is formed of an elastomer and is disposed about the lattice and within the voids of the lattice. The foot is configured to engage a surface to support the body relative to the surface.
RING DAM AND METHOD FOR MANUFACTURING A RING DAM
A ring dam, fitting between a fluid container and a housing for the fluid container, may include an extruded Polyethylene (EPE) foam having an Ethylene-Vinyl Acetate (EVA) additive.
Gasket and method for mounting same
A gasket is provided which is configured so that a gasket body is easily separated from a carrier film and the positional shift of the gasket body in stacking can be prevented. The gasket has a combination of a gasket body which contains only a rubber-like elastic body and which, in order to seal a gap between one member and the other member, is mounted in the other member and a carrier film separably stuck to one surface side in the thickness direction of the gasket body, in which an engagement portion is formed in the other surface in the thickness direction of the gasket body at a position corresponding to a portion to be engaged formed in the other member, and the gasket body is mounted in the other member by engagement of the engagement portion and the portion to be engaged.
Method of manufacturing plate-integrated gasket
To effectively prevent a breakage of a plate when a gasket body formed of a rubber-like elastic material is integrally molded at both faces of the plate formed of a brittle material such as carbon. In order to attain this object, there is provided a method of manufacturing a plate-integrated gasket in which a gasket body formed of a rubber-like elastic material is integrally formed at both sides of a portion along a peripheral edge of a plate in the thickness direction, where an area located between gasket molding cavities defined by clamping the plate between split dies of a metal mold in the plate is formed to be a relatively thick portion at a position, facing an opening of a gate through which a molding material is injected into the cavities, and in the vicinity thereof.
SYRINGE GASKET
Provided is a syringe gasket including a first member, and a second member connected to the first member and coupled to a plunger rod of a syringe. The first member includes a top face contacting with the liquid, and a first side circumferential face that faces an inner circumferential face of a barrel of the syringe. The first side circumferential face has, at an end portion thereof close to the second member, a ring-like trimmed face. An inert film is laminated on the top face and the portion of the first side circumferential face other than the ring-like trimmed face. The second member includes a second side circumferential face that faces the inner circumferential face of the barrel, and a ring-like protruding portion that projects outward in the radial direction from the second side circumferential face. The ring-like protruding portion at least partially covers the ring-like trimmed face.
NON-METALLIC HIGH PRESSURE HIGH TEMPERATURE HIGH CHEMICAL COMPATIBILITY FLANGE ISOLATION GASKET
A non-metallic flange isolation gasket kit sealing flanged pipeline connections and flanged vessel connections while providing electrical isolation protection between flanges suited for high-pressure and high-temperature cathodic protection applications is presented. The invention protects flange faces from media induced corrosion and mitigates flange rotation induced fatigue and failures. The invention comprises of a retainer, a seal, and a seal pre-load structural ring. The seal pre-load structural ring is inserted into the seal, and seal outer diameter surface is joined to the retainer inner diameter surface. A second embodiment comprises of a composite gasket blank, comprising of a retainer and a seal, and a seal pre-load structural ring. The seal outer diameter surface and the retainer inner diameter surface are joined by thermal fusion bonding. The invention may further comprise one or more gasket seating stress stabilizers and/or a centering ring. Tapered retainer upper and lower surfaces decrease flange rotation.
SYSTEMS AND METHODS FOR SEALANT INJECTION MOLDING
A mold tool is provided that includes plural mold sub-volumes configured to receive a sealant, a mold channel in fluid communication with the mold sub-volumes, a sealant injection port in fluid communication with the mold channel, vacuum application ports in fluid communication with the mold sub-volumes, and an air control system. The air control system is operably coupled to the mold sub-volumes and the mold channel, and is configured to apply a vacuum to the mold sub-volumes via the vacuum application ports.
METHOD OF FORMING SEALING ELEMENTS FOR USE IN A MECHANICAL SEAL
A system and method for forming sealing elements for a mechanical seal that are shaped so as to fill substantially completely the groove that seats the sealing elements. The mechanical seal includes a holder assembly, sleeve assembly, balance piston or any other rotary or stationary part having one or more grooves formed therein and a sealing element that seats within the groove.
