Sealed threaded joint for oilfield pipes
PATENTS Cosmetics case having structure of dual seal Applicant/Inventor: S.-I. Kim, Korea A cosmetics case having a dual sealing structure is designed to retain the volatile solvents in the cosmetic and hence ensure a longer life for the cosmetics. Both the foldable mirror and the lid, containing the make-up tools are sealed. Publication number: WO/2008/100025 Publication date: 21 August 2008
retainer that is designed as an alternative to various metal seal designs such as C, V and O-rings. It is supported in a retainer which appears to be to prevent damage prior to assembly. The flanges for use with the seal also have a bead protrusion presumably to increase contact stress. Publication number: WO/2008/100540 Publication date: 21 August 2008
Gasket, a bipolar battery and a method for manufacturing a gasket Applicant: Nilar Int. AB, Sweden This invention relates to gaskets for use in a starved electrolyte bipolar battery. The bipolar battery has a gasket made from a hydrophobic material with a built- in gas channel arranged between adjacent biplates, with gas channels within the gaskets that create a common gas space within the battery and at the same time electrolyte is prevented from migrating between cells. Currently gaskets with a high pre-load are required. This patent describes a gasket comprising a frame with elastomer beads to provide the required deformation with lower pre-load. Publication number: WO/2008/100207 Inventors: D. Hock et al. Publication date: 21 August 2008
Ring seal and retainer assembly Applicant/Inventor: M. Doyle, USA This patent describes a metal seal and
(28) is mounted in the stationary section. Publication number: WO/2008/102579 Inventors: A. Torii et al. Publication date: 28 August 2008
Sealed threaded joint for oilfield pipes Applicant: Obschestvo S. Ogranichennoj Otvetstvennost’yu ‘Tmk-Premium Servis, Russia A variation on the threaded pipe connections for oil well casing pipes is described. The sealing section comprises a tapered female section with an angle of 5–25°, which mates with a spherical end section to the male pipe end. The thread is non symmetrical in profile with a negative angle on the bearing face. Publication number: WO/2008/103069 Inventors: A.V. Emelianov et al. Publication date: 28 August 2008
Gas diffusion layer with integrated seal for use in a fuel cell A cross-section of the bearing seal with integral sensor, WO/2008/102579.
Sensor-equipped seal device and wheel bearing Applicant: NTN Corporation, Japan A wheel bearing seal with integral sensor is described. The pulser ring (27) is included in the seal cassette sleeve assembly and the sensor
Applicant: Freudenberg-NOK GP, USA A membrane electrode assembly is provided for use in a proton-exchange membrane (PEM) fuel cell. An external manifold and seal are moulded directly to the gas diffusion layers. The integrated manifold and gas diffusion layers are formed as duplicate components which can be oriented 180° offset to one another to create the MEA assembly. Publication number: WO/2008/103217 Inventor: J.J. Heystek Publication date: 28 August 2008
Flexible cannula with seal
A metal ring seal with retainer designed as an alternative to regular metal seal designs, WO/2008/100540.
December 2008
Applicant: Tyco Healthcare Group LP, USA A flexible cannula including a sealing device that is intended for microsurgery procedures is described. It is intended to provide an improved flexible self- sealing cannula which is compact in size and prevents the loss of insufflation gas while providing a user with the ability, and manoeuvrability, to perform endoscopic procedures. Publication number: WO/2008/103305 Inventor: R.C. Smith Publication date: 28 August 2008
