Method of manufacturing seal-integrated type membrane electrode assembly
PATENTS provide an improved and comfortable fit to the face of the patient. Patent number: WO/2007/104042 Inventor: P.C.F. Ho Publication date: 13 September 2007
Sliding ring seal Applicant: Federal-Mogul Burscheid GmbH. Germany A development of the duo-cone type of face seal that is used for applications such as earthmover wheel bearings is described. This design uses a single coned seal ring and is intended for higher speed applications such as pinion shafts where lip seals are currently often used because of the speed limitations of duo-cone seals. The other major difference is that the lubricating oil is exposed to the outer diameter of the seal. It is arranged in a cartridge unit with the hub components such that access for contaminant to the seal is restricted. Patent number: WO/2007/104272 Inventor: H-H. Zutz Publication date: 20 September 2007
Seal ring Applicants: NTN Corp. Japan A piston ring with a stepped butt joint is described that is designed to allow the passage of contaminant particles from the pressure side to the low pressure side without damaging the counter-faces. Patent number: WO/2007/105589 Inventor: K. Kakehi Publication date: 20 September 2007
Seal for the flow switch valve housing outlet Applicant: Axial Technologies Ltd. New Zealand A cap for disposable drinks bottles is described that contains a switched valve to retain the contents. A ball valve is illustrated and a key feature of the design is the inclusion of a seal. A labyrinth seal and induction seal are mentioned in the text. Patent number: WO/2007/105968 Inventors: M.R. Kessell et al. Publication date: 20 September 2007
Cover for culinary article with silicone gasket Applicant: SEB SA. France A seal for the lid of a casserole dish or similar culinary equipment is described. A feature claimed is that the seal extends beyond the perimeter of the lid. The purpose of this includes the possibility of including a vent to allow the escape of steam during the cooking. Patent number: WO/2007/107656 Inventors: N. Bergeret, C. Lorthioir and P. Cuillery Publication date: 20 September 2007
Waterproof gasket An earth mover bearing seal modified to a single cone face to achieve higher speeds.
Method of manufacturing seal-integrated type membrane electrode assembly Applicant: Toyota Jidosha Kabushiki Kaisha, Japan This patent involves the design of a fuel cell membrane to ensure that it contains sufficient holes to allow circulation of seal material to both sides of the membrane during the moulding of the seals. Patent number: WO/2007/105073 Inventor: T. Sasaoka Publication date: 20 September 2007 14
Sealing Technology
Applicants: NOK Corp. Japan A waterproof gasket for the body of a mobile phone case is described. It is intended to provide easy handling during assembly and maintain desirable sealing capability. The gasket is manufactured from elastomer and it has as surface layer of a reactive surface treatment agent. Patent number: WO/2007/108560 Inventors: H. Kanagae and D. Shojima Publication date: 27 September 2007
Cannula stabilization seal Applicant: Applied Medical Resources Corp. USA An inflatable stabilization seal is described that can be used with existing cannulas for forming
a gas-tight seal with tissue in a body wall during a surgical operation. Patent number: WO/2007/109700 Inventors: C.C. Hart, G.Au and K. Pravongviengkham Publication date: 27 September 2007
Surgical sealing element, surgical seal, and surgical sealing system Applicant: Aesculap AG & Co. KG, Germany The invention relates to a surgical sealing element for a trocar and/or for sealing the shafts of elongate surgical instruments during insertion into a human or animal body. To improve the surgical sealing an undulated shape seal that folds without kinks is used. Patent number: WO/2007/110371 Inventors: T. Schweitzer and R. Mayenberger Publication date: 4 October 2007
General purpose fluid-tight gasket Applicant: Belgicast Internacional, s.l.u. Spain A circumferential clamp type of pipe connector is described that is intended to provide the capability to connect pipes of different sizes. One of the U-section seals is of increased section with additional sealing lips to accommodate variations in pipe diameter. Patent number: WO/2007/110453 Inventor: J.A. Azpiazu Núñez Publication date: 4 October 2007
Adjustable seal Applicant: Krausz Metal Industries Ltd. Israel This invention relates to external sealing of pipe joints. A single strip of seal with U-section at both ends is used in conjunction with a circumferential clamp. It is easily cut to length to suit individual pipe sizes. Patent number: WO/2007/110856 Inventors: E. Krausz and A. Chiproot Publication date: 4 October 2007
Scroll machine using floating seal with backer Applicant: Emerson Climate Technologies, Inc. USA This patent is concerned with the internal sealing of hermetic scroll type compressors used in refrigeration systems. A floating plate that seals the scroll also has an internal and external lip seal for dynamic sealing. Patent number: WO/2007/111903 Inventor: Z. Wang Publication date: 4 October 2007
