Seal guard
PATENTS Duckbill seal with fluid drainage feature Applicant: Ethicon Endo-Surgery Inc, USA A duckbill seal in a trocar assembly has an inner surface of the seal body configured to selectively promote movement of fluid away from the central portion of the seal. Publication number: WO/2009/005986 Inventors: P.T. Franer et al. Publication date: 8 January 2009
Seal guard Applicant: The Timken Company, USA An improved method of sealing wide inner ring bearings such as those used in the food industry is described. It is designed to provide improved resistance to washing down etc. An elastomer seal is fitted to the outer seal guard and includes an angled external surface (22A) adapted to deflect external contaminates away from direct impingement upon the seal components (18). Publication number: WO/2009/006279 Inventors: A.S. Kulkarni et al. Publication date: 8 January 2009
Seal for valve or pump Applicant: Valois SAS, France This invention relates to a seal for a valve or a pump, intended for a fluid product dispensing device. The seal includes an elastomer obtained by metallocene catalysis and at least one basic mineral filler. Publication number: WO/2009/007651 Inventor: P. Léoné Publication date: 15 January 2009
A cylinder head gasket that has individual seal elements for all openings and also a flexible mounting element (4), WO/2009/010109.
novel feature is the use of an adhesive in the form of a spray to bond the layers. This is said to be an improvement over the adhesive normally used. Publication number: WO/2009/008022 Inventor: A. Fenaroli Publication date: 15 January 2009
Mechanical seal device Applicant: Eagle Industry Co Ltd, Japan A dual seal arrangement is described that appears to be intended for applications with high solids content. The product side seal and the housing are designed to avoid clogging around the seal. The seal cover plate includes a tapered extension that protrudes into the seal housing of the pump. The product side seal is designed with a smooth exterior and springs away from the product. Publication number: WO/2009/008288 Inventor: H. Takahashi Publication date: 15 January 2009
Mechanical seal device Magnetically-controlled rotary seal Applicant: Eaton Corporation, USA A non-contacting rotary face seal assembly designed for hydrostatic or hydrodynamic mechanical face seals is described. To ensure that the faces are separated on start up, before the hydrodynamic or hydrostatic separation is generated, magnets oriented to provide a repulsion force are built into the seal face components. Publication number: WO/2009/007826 Inventors: Z. Xiaoqing et al. Publication date: 15 January 2009
Applicant: Eagle Industry Co Ltd, Japan This patent describes a small-sized seal, but this may wish to indicate a compact housing arrangement. Both a narrow bore housing and a very short length dual seal arrangement are shown. In both cases flow diverters and a pumping ring are used for buffer circulation. The pumping ring includes a series of either radial or angled holes. Publication number: WO/2009/008289 Inventor: H. Takahashi Publication date: 15 January 2009
Packing for food processing plant Layered metallic gasket Applicant: Seval SrL, Italy Although this patent uses the term head gasket, this appears to be due to the translation as it discusses the manufacture of industrial multilayer gaskets of profiled metal sheet and gasket material. The
May 2009
Applicant: Aram Corporation, Japan A seal for use in food processing plant is described. The seal is a flanged O-ring to fit hygienic flanges and is composed of rubber and black iron oxide powder. Publication number: WO/2009/008369
Inventor: S. Yoshitomi Publication date: 15 January 2009
Outer pin seal Applicant: Deere & Co, USA This seal is designed for the pivot joints of agricultural and earthmoving machinery and fits circumferentially around the external gap of the joint. It has a wedge shaped cross section to self adjust over a range of gap widths. Publication number: WO/2009/008941 Inventors: T.A. Klousia et al. Publication date: 15 January 2009
Radial seal and method of making Applicant: Federal-Mogul Corporation, USA A method of manufacturing a radial shaft seal which includes both elastomer and PTFE components directly moulded to the casing is described. The design and manufacturing method is claimed to provide a full length lay down contact of the PTFE and overcome fitting problems experienced with existing types. Publication number: WO/2009/009410 Inventor: F.R. Hatch Publication date: 15 January 2009
Cylinder head seal having individual sealing elements Applicant: Federal-Mogul Sealing Systems GmbH, Germany This describes a cylinder head gasket that has individual sealing elements for combustion chambers (2) and fluid passages (6). An elongated flexible mounting element (4) encloses the individual seal elements and also contacts them (20 and 22). A number of different detail designs are illustrated. Publication number: WO/2009/010109 Inventor: R. Prehn Publication date: 22 January 2009
