Hot runner nozzle having split ring seal
PATENTS Oil seal Applicants: Toyota Jidosha Kabushiki Kaisha and Arai Seisakusho Co., Ltd. Japan An oil seal is described that has a pair of concentric seal lips contained in a rotating housing and a stationary flange between them. The inner lip does not contact the stationary flange when the shaft is stationary but moves to close the gap, presumably due to centrifugal force. A wide selection of geometries is illustrated. Patent number: WO/2007/097320 Inventors: T. Suzuki et al. Publication date: 30 August 2007
Method and system for applying a seal to a door of a motor vehicle Applicant: ThyssenKrupp Drauz Nothelfer GmbH, Germany The application takes place in two stages. In the first stage, a stationary roll-on head is used to place a seal, which is cut to size from an endless sealing band, onto plug-on and press-on elements of a clamping plate. The clamping plate with seal is brought up to the door and is pressed on to the adhesive surface by means of press-on elements. Application is exclusively with mechanical means. Patent number: WO/2007/082915 Inventor: N. Fenger Publication date: 26 July 2007
Electroconductive gasket material Applicants: Seiren Co., Ltd. and KB Seiren, Ltd. Japan This invention provides an electro-conductive gasket material which is easy to manufacture in any desired shape, has cushioning properties, can significantly reduce the amount of cut chips produced in punching and, at the same time, can significantly reduce the occurrence of loosening or fuzzing. The electro-conductive material can comprise a laminated integrated composite sheet of a nonwoven fabric of a self-bonded continuous organic fibre and an organic fibre structure sheet, the lamination integrated composite sheet having been metalized. Patent number: WO/2007/083822 Inventors: K. Takebayashi et al. Publication date: 26 July 2007
Surface seal and method for producing sealed joints Applicant: Airbus Deutschland GmbH, Germany This patent refers to the sealing of a pressurised aircraft structure such the fuselage and is designed to ensure that a sealing layer with some damping properties remains between the mating surfaces 14

after they have been riveted or screwed together. A surface seal is formed with a pressure resistant plastic film that is provided with a pressure sensitive adhesive layer on both sides. Due to the presence of the pressure resistant film any displacement of the surface seal in the region of the bore is largely prevented during the tightening of a joint and fretting corrosion that can lead to premature fatigue cracks in the joint is avoided. Patent number: WO/2007/085421 Inventors: H. Stehmeier and T. Beumler Publication date: 2 August 2007
Multistage brush seal Applicant: Siemens Aktiengesellschaft, Germany This patent describes a multistage brush seal for steam turbines which is designed to overcome the conservative configuration of conventional multistage brush seals. The aim of the invention is to design a brush seal that allows a more precise prediction in respect of the pressure difference in a single stage and thus provides a more precise dimensioning of the brush seal and achieve possible savings. The invention proposes that the adjacently arranged brushes have varying configurations to optimise sealing of different parameters. Patent number: WO/2007/085587 Inventors: M. Neef, N. Sürken and K. Urlichs Publication date: 2 August 2007
Hot runner nozzle having split ring seal Applicant: D-M-E Co. USA An injection moulding machine is described in which a split ring seal is fitted in a groove on the exterior of the nozzle body. The seals maintain separation of the periphery of the nozzle body from the surface of the recess with the outlet positioned within the recess. The seals have overlapping end segments abutting at the outlet positioned within the recess. Patent number: WO/2007/086945 Inventors: J. Adas and C.V. Kovacic Publication date: 2 August 2007
Seal for a prefilled medical jet injection device Applicant: Novo Nordisk A/S. Denmark A sealing membrane for the nozzle of a jet injection device is described. It is intended to maintain sterile conditions within the nozzle. Both primary and secondary membranes and the potential use of a back up sealing plug are discussed. Patent number: WO/2007/088112 Inventor: J.U. Poulsen Publication date: 9 August 2007
Trapping detection seal for opening leaves of vehicles
Radial seal filter with multi-component housing
Applicant: Renault s.a.s. France This patent describes a sealed capacitive sensor fitted in the top of a window frame on a vehicle. It is part of the safety system to sense for trapping in an electric window and is designed to overcome problems of contamination of the sensors by debris and water. Patent number: WO/2007/085762 Inventors: H-G. Nguyen, C. Seyranian and J. Jost Publication date: 2 August 2007
Applicant: Cummins Filtration, Inc. USA This patent covers a method of manufacturing a filter body housing in which three different components of the assembly form the three sides of the O-ring groove. The components are all plastic and may be co-moulded or spun welded. Patent number: WO/2007/089662 Inventor: C.M. Thomas Publication date: 9 August 2007
