Device provided with a movable seal system
PATENTS
Device provided with a movable seal system Applicant/Inventor: A. Gaide (Switzerland) This patent describes a moveable seal that is an essential component of a rather complex sounding device. It may be operated by
either a mechanical, hydraulic or pneumatic arrangement. The function is the cleaning of toilet seats. Patent number: WO 2006/046208 Publication date: 4 May 2006
Pipe joint and male joint Applicant: Nitto Kohki Co Ltd, Japan This is a patent for a self-seal coupling that has two separate pressure supplies. One will operate at 25 MPa and the other at 90 MPa. The design
includes specific provision to prevent the O-rings becoming dislodged during operation of the coupling. Patent number: WO 2006/046406 Inventor: K. Matsumoto Publication Date: 4 May 2006
Metal gasket for cylinder head Applicant: Nippon Leakless Industry Co Ltd, Japan This patent describes a multilayer laminated type metal gasket for a cylinder heads. The specific feature discussed is a claw-like projection (3a) formed on either of an outer side step adjusting sheet (3) which extends from the position of the cooling water jacket to the outer edge. An
Shaft seal dustproof structure of turbo molecular drag inner side step adjusting sheet (4) is pump thicker than the outer adjusting sheet. The claw connects the inner and outer adjusting sheets. The step between the sheets is used to control the balance of pressure between the various sealing beads of the gasket. Patent number: WO 2006/046662 Inventors: Y. Matsushita et al. Publication Date: 4 May 2006
Applicant: Osaka Vacuum Ltd, Japan A shaft seal dustproof structure of a turbo molecular pump is described. The seal is required to prevent intrusion of corrosive gas or fine particles into the motor housing of the pump. There is a purge gas supply port in the motor housing, a shaft seal consisting of a
clearance seal portion at the outer circumferential part of boss projecting to the central part the rotor and a centrifugal blade in the purge gas passage leading to pump chamber. Patent number: WO 2006/051675 Inventors: T. Ohbayashi and M. Iguchi Publication date: 18 May 2006
Seal for holes in car bodies Applicant: Tesa AG, Germany The invention relates to a stamped product which is used to provide a durable seal for holes in car bodies. It comprises a base layer with a thermo-activable adhesive at least
partially on one side and a heatresistant layer. It is intended for use on both steel and plastic panels. Patent number: WO 2006/053827 Inventors: F. Kolmorgen et al. Publication date: 26 May 2006
Mechanical seal device
Plan of the gasket described in WO 2006/046662, showing the position of the claw features and a section showing the detail of the claw.
Applicant: Eagle Industry Co Ltd, Japan A mechanical seal design is described that will suppress vibration of the rotating seal ring and avoid contact of the seal faces to minimize generation of debris. The rotary seal ring (10) has circular arc-like annular grooves (12) arranged on the face. The arcs are
divided by partition walls (13). The stationary seal ring has a port for the supply of pressurized fluid to the grooves. The geometric relationship of the grooves and port is described. Patent number: WO 2006/051702 Inventors: T. Yanagisawa, K. Akiyama and M. Ito Publication date: 18 May 2006
Filter element with canted seal support and frame Applicant: Baldwin Filters Inc, USA This patent describes a seal arrangement for filter elements used as engine or compressor air inlet filters. The purpose is to provide an improved filter element that can be manufactured more economically. A filter element complete with seal
is described. The second patent covers the support frame for the filter and the attachment of the seal. Patent numbers: WO 2006/049701 and 049702 Inventors: G.W. Brown and S.J. Merritt Publication date: 11 May 2006
Gasket assembly Applicant: Federal-Mogul Corporation, USA This invention is a gasket assembly which permits the incorporation of multiple seals of potentially different elastomer types in a single gasket assembly without the need for
Sealing Technology September 2006
co-molding of the seals on the gasket carrier. The gasket comprises a stack of seal carriers each of which has a sealing aperture that has a sealing bead. Patent number: WO 2006/052432 Inventor: G.A. Boeve Publication date: 18 May 2006
Cross-section of the mechanical seal with pressurized feed to the seal face described in WO 2006/051702, and a detail of the annular face grooves.
