Piston with hardened ring grooves
FEATURE PATENTS
Patents Roll type gasket of LCD panel, and manufacturing method Applicants/Inventors: Y.B. Namkung and K.T. Park (Korea) A gasket for sealing and protecting an LCD panel is described. In particular, it is easily fitted in position and will not slide, which makes
assembly more economical. It also provides shielding and protection from vibration. Patent number: WO 2006/095948 Publication date: 14 September 2006
Rotary sealing joint Applicant: Siemens Automotive Hydraulics SA, France The invention concerns a safety device for preventing overpressure occurring in the oil-lubricated section of an engine-driven, highpressure gasoline transfer pump. It is important to ensure that overpressure of the oil does not rupture the pump casing, causing an escape of gasoline. In the event of overpressure in the lubricant chamber
it is permissible to vent the oil back into the engine oil gallery. In order to avoid the additional cost of a relief valve, the shaft seal is designed to fail. The seal has an outer annular area that is both thinner and of a lower hardness elastomer than the remainder of the seal. Patent number: WO 2006/103330 Inventors: F. Sellas and D. Veret Publication date: 5 October 2006
Piston with hardened ring grooves Applicants: MAN B&W Diesel AG, Germany The piston is manufactured from a nitride-forming base alloy. The fire land and at least the top piston ring groove are then provided with an additional wear-protective and anti-corrosive layer nitride layer. This is produced
Device for separating gasket of refrigerator doors Applicant: LG Electronics Inc, Korea A device for separating the gaskets on a two-door refrigerator is described in this patent. The device acts to separate the gaskets of the pair of doors when one of the doors is opened. A gasket arrangement with improved seal-
Gasket for cylinder head cover
Joint member for pipe joint
Applicant: NOK Corporation, Japan This patent describes a gasket or grommet type device that may be used for sealing an opening in components such as a cylinder head cover where a tube passes through. To avoid damage on assembly the outside diameter is similar to or
Applicant: Nitto Kohki Co Ltd, Japan This patent describes the sealing of a self-seal, quick-release type fitting which is designed to prevent the seal being dislodged by the fluid flow. The seal arrangement is such
less than the diameter of the hole. Provision is made for radial expansion of the gasket after assembly. The gasket can then be used to seal orifices that are not manufactured to precise dimensions. Patent number: WO 2006/077677 Inventor: T. Yanagi Publication date: 27 July 2006
Method for testing a seal Applicant: Patent-TreuhandGesellschaft für Elektrische Glühlampen mbH, Germany This patent describes a test to measure the mechanical properties of the ceramic stopper used in high pressure gas discharge lamps. The
stopper is compressed between a pair of plates, and the loading required to create cracks in the ceramic is observed. Patent number: WO 2006/079309 Inventor: S. Lampenscherf Publication date: 3 August 2006
by plasma-nitriding or plasmanitrocarburising in a nitrogen or nitrogen and carbon atmosphere. Patent number: WO 2006/097265 Inventors: A. Lüpfert and S. Knobloch Publication date: 21 September 2006
ing is achieved when the doors are closed, and the positive separation improves the operating lifetime of the door seals. Patent number: WO 2006/101291 Inventors: J.H. Oh et al. Publication date: 28 September 2006
that the seals are located by the housing during disengagement of the fitting. Patent number: WO 2006/077716 Inventors: H.Kitagawa, M.Imaizumi and K.Matsumoto Publication date: 27 July 2006
Sealing ring for universal joint bush Applicant: Schaeffler KG, Germany This invention relates to a seal for the needle bearing bush for a universal joint. The seal is designed with a vent flap (14), which allows
trapped air to escape when the bearing is fitted to the journal of the joint. Patent number: WO 2006/079381 Inventors: F. Jauernig et al. Publication date: 3 August 2006
Gasket assembly for plate heat exchanger Applicant: Alfa Laval Corporate AB, Sweden This invention relates to the gasket assembly of a plate heat exchanger, and particularly for semi-welded designs used in the food industry. The gasket seals between the welded pairs of plates. The design minimizes
dead zones that can cause accumulation of bacteria, and facilitates ease of cleaning the plates, while the semi-welded construction reduces the number of seals required. Patent number: WO 2006/080874 Inventor: M. Svensson Publication date: 3 August 2006
Metallic flat seal Applicant: Reinz-DichtungsGmbH, Germany This patent is concerned with the design of spacers for multilayer

steel cylinder head gaskets. Patent number: WO 2006/079452 Inventors: G. Egloff et al. Publication date: 3 August 2006
Universal joint bearing with a seal that vents trapped air as the joint is assembled, from WO 2006/079381.
