Method for the production of flat seals, and flat seal
PATENTS Hose joint Applicant: Toyox Co Ltd, Japan This connector for flexible hoses has an indicator to show that the fitting is fully engaged. As the cap is slid over the grip ring it engages with a lug holds it in position and indicates that the cap is in the correct position to energise the grip ring. Publication number: WO/2008/117745 Inventor: K. Horiichi Publication date: 2 October 2008
used in series if required with certain cavities being exposed to the down-hole fluids for pressure equalisation if required. The seal is achieved by elastic deformation across the seal between points 140 and 144. The control system for the valve and actuator are also described in the patent. Publication number: WO/2008/118916 Inventors: D.E. Bane et al. Publication date: 2 October 2008
Device for supporting substrate and examiner for seal pattern of LCD cell Applicant: Snu Precision Co Ltd, Korea Equipment for supporting and examining the seal pattern of an LCD cell is described. It includes a correction device coupled to the bridge to examine and repair a seal pattern of a substrate. Publication number: WO/2008/117953 Inventors: H.Y. Lee et al. Publication date: 2 October 2008
Pitch bearing containment seal Applicant: The Boeing Co, USA A flexible, resilient seal that is designed to protect the bearing in a pitch joint of a helicopter blade assembly from contaminants is described. These are typically a dry bearing subject to oscillating load as the blades rotate. Previous designs have incorporated a seal directly on surfaces of the pitch joints which makes it difficult to add this type of seal after the joint has been assembled, such as in a retrofit application. A number of seal arrangements that include a bellows to accommodate relative movement and a seal lip of the bearing housing are illustrated. Publication number: WO/2008/118236 Inventor: S.R. Carbaugh Publication date: 2 October 2008
Device for positioning a fitting in a vehicle door seal groove The all metal seal as used in the actuator for control of a subsurface safety valve, WO/2008/118916.
Method for the production of flat seals, and flat seal Applicant: Federal-Mogul Sealing Systems GmbH, Germany A method for mechanically connecting multilayer metal gaskets is described. A punch with approximately circular cross-

Applicant: Renault sas, France A seal assembly for a vehicle door that is plastically deformed to assemble it in the groove. There are also a series of guides which engage with locating elements to secure the seal in position. Publication number: WO/2008/119898 Inventor: S. Mossu Publication date: 9 October 2008
Gasket for food-batching device Applicant: Bisio Progetti SpA, Italy This patent describes a gasket that is used to seal between a retaining collar and a volume measuring cup of a food batching device. A feature of the gasket is that it is retained on the retaining plate. Publication number: WO/2008/120254 Inventor: S. Bisio Publication date: 9 October 2008
Seal member and brush for image forming apparatus
Subsurface safety valve with metal seal Applicant: Baker Hughes Inc, USA A metal seal is proposed to improve the reliability of the hydraulic actuator used to operate in hostile down-hole environments for the operation of subsurface safety valves. This design allows a number of seals to be
section (13) partially cuts the layers at defined points (14), and at least some of the remaining material is deformed outside the respective cut zone (7, 8, 9) to form what are defined as bent zones (4, 5, 6). The cut zones are circular and the bent zones are straight. Burrs (7’) of at least one of the layers (10–12) are effectively connected to the material of at least one other layer (10–12) in order to form a removable clamping connection.
