Sealing structure using gasket
FEATURE PATENTS Resilient seal Applicant: American Seal and Engineering Co Inc, USA This invention is a metal seal that is intended as an improvement on a metal C-seal or similar geometries for either high temperature or cryogenic duties, where a radial seal is required that also has to accommodate relative axial motion of the sealed components
Seal profile or successive re-assembly. It takes the form of a J or hooked shape cross-section. This design provides improved sealing where there is lateral offset, angular or axial misalignment. A number of potential profiles are discussed. Patent number: WO 2006/085853 Inventor: H.P. Halling Publication date: 17 August 2006
J-section metal seal that is designed to provide a more resilient seal to improve performance in misaligned conditions, from WO 2006/085853.
of the profile, a chamber is provided for a sensor in the middle and front region of the seal profile. Sealing lips extend outwards from the front region of the profile, near to the transition from the face to the sensor chamber, at an angle. Patent number: WO 2006/087131 Inventor: T. Katzensteiner Publication date: 24 August 2006
Cross-section of a seal for train doors that contains a sensor to monitor for trapped objects, from WO 2006/087131.
Sealing structure using gasket
Fluid-activated shaft seal Applicant: Midé Technology Corporation, USA This patent describes a seal that is intended for rotating shafts that pass through bulkheads, such as ship propeller shafts. It is concerned with avoiding excessive wear that may occur if the shaft is rotated when the seal is not in contact with liquid. The seal is designed to be a clearance when no liquid is present. When liquid is present a gel material that expands in
Applicant: Knorr-Bremse GmbH, Austria This invention relates to a seal profile for the main sealing edges of sliding doors, swinging-sliding doors and compartment doors on motor vehicles, in particular rail vehicles. The design simultaneously provides sensitivity to trapped objects and sealing efficiency. In the cross-section
the presence of a liquid energizes the seal into contact with the shaft. Patent number: WO 2006/086039 Inventor: M. van Schoor Publication date: 17 August 2006 Editor’s note: The patent discusses a seal that energizes in the presence of a fluid, but I have presumed in my synopsis that it actually means liquid. Unless it is stored in a vacuum it must always be in contact with a fluid.
Applicant: NOK Corporation, Japan An integral seal for providing a radial seal on the lid of a container is described in this patent. It may be integral with either the
container or the lid, and will not cause deformation of a relatively thin container. Patent number: WO 2006/087948 Inventors: E. Isono et al. Publication date: 24 August 2006
Seal material for semiconductor production apparatus Applicant: Nippon Valqua Industries Ltd, Japan This seal material is particularly suitable for a semiconductor production apparatus, as it provides good resistance to cracking in plasma environments. It comprises 50–80% ethylene tetrafluoride-perfluoroalkyl vinyl
ether perfluoroelastomer (FFKM), with the remaining 20–50% of fluorocarbon (FKM). The type of fluorocarbon is not specified in the English abstract. Patent number: WO 2006/087942 Inventor: M. Okazaki Publication date: 24 August 2006
Flame-retardant EMI shielding gasket
Example of the gel energized shaft seal intended for marine applications, from WO 2006/086039.
Sealing Technology December 2006
Applicant: Parker-Hannifin Corporation, USA A flame-retardant, electromagnetic interference (EMI) shielding gasket is described. It includes a resilient core of foamed elastomer with an electrically conductive fabric outer
layer. The seams of the fabric are bonded to the core with a layer of a cured, thermoset, flame-retardant film adhesive. Patent number: WO 2006/088565 Inventors: B.R. Cloutier et al. Publication date: 24 August 2006 13
