Improved sealing system for vehicles
PATENTS Seal for use in a dispensing apparatus Applicant: Consort Medical Plc, UK This invention relates to a seal for a valve used in a dispensing device for pharmaceuticals. The seal is formed from an composition comprising one or more elastomers; and a cross-linking agent that is consists of an aliphatic dialkyl peroxide and/or an aliphatic perketal peroxide. The seal may be used for dispensing pressurised fluid in the form of an aerosol. It is particularly suitable for use in dispensing devices such as pressurised metered dose inhalers (PMDIs) and in medical check devices suitable for dispensing pharmaceuticals. The required material properties necessary for good seal performance, required by pharmaceutical applications, include chemical compatibility (swell); tensile strength; permanent compression set; stress relaxation; elastic modulus; regulatory compliance; low permeability to fluids and gases; low levels of extractables and leachables; and stable properties after extraction. Patent number: WO/2011/067574 Inventor: D.S. Ohbi Publication date: 9 June 2011
Mechanical seal Applicants/Inventors: P.N. Hughes, A.M. Hughes, R.A. Hughes and P.A. Hughes, UK A seal is disclosed for an opening between a movable object and a road surface. It is designed to seal between the road surface and an apparatus – below or level with the road surface. It is specifically designed for equipment below the road surface that may be actuated by a vehicle. The seal in line with the road surface is designed to be elastic and is configured to be subjected to wear. A second seal, below the surface, typically has a bellows structure in order to absorb movement and will continue to provide sealing action while the upper seal is being replaced. Patent number: WO/2011/067609 Publication date: 9 June 2011
Oil seal Applicant: NOK Corp, Japan The oil seal detailed by this patent is configured in such a manner that even after wear of the seal lip progresses, a reduction in the proportion of a coating occupying the contact width of the seal lip is minimised in order to suppress, to a low level, an increase in torque. The patent describes an oil seal that has a lip which consists of an elastic body and also a coating (affixed to the seal lip). The seal

lip and the coating are adapted so that they make contact with the shaft at the same time. The shape of the coating has a thickness that increases gradually from the tip of the seal lip. The coating is formed using a mould. A hollowed-out section is provided in the ‘‘coating-affixing’’ surface of the seal lip. The coating is embedded in the hollowed-out section. Screws which perform a pumping action are formed on the surface of the coating. Details of the material coating are not provided in the English abstract. Patent number: WO/2011/067990 Inventors: T. Nakagawa, H. Nagahamaya, T. Nishigaki and M. Tanida Publication date: 9 June 2011
Gasket and structure for an exhaust pipe connection Applicant: Isuzu Motors Ltd, Japan Details are provided of a gasket and a structure for an exhaust pipe connection. According to the patent, even if a liquid reducing agent leaks from the main bead of the gasket, this design prevents it from spilling onto the bolts. In this way it prevents deterioration and breakage of the bolts. Apart from the sealing beads used for the exhaust flange, additional sealing beads are provided around the bolt holes. Patent number: WO/2011/068202 Inventors: I. Ohara, N. Hiraki and T. Mashiko Publication date: 9 June 2011
Improved sealing system for vehicles Applicant: Guardian ,QGXVWULHV&RUS86$ In specific embodiments of this invention, improved sealing systems that include flexible seals which are integrally formed (for example, co-extruded) with other vehicle components (and/or methods of making these) are provided. All sealing system components may be integrated into the trim and/or other components of the vehicle (for example, structural elements of the vehicle). For instance, in certain embodiments, the current U-shaped seal that typically is used to receive the glass for a window may be replaced with seal members attached to elements of the overall vehicle construct. Other embodiments discussed accomplish this integration by forming seal members together with the trim components, for example, as a part of the roll form and/or extruding processes. Patent number: WO/2011/068532 Inventors: D. Prater and T. Belliston Publication date: 9 June 2011
Boiler thermal insulation and sealing device Applicant: Shanghai Boilier Works Ltd, China A thermal insulation and sealing device, between a boiler platen heating surface tube bundle and furnace ceiling tubes, is provided. This is used to seal a junction between the furnace ceiling tubes and the platen heating surface tube bundle. The device includes a sealing box, which is sleeved on the outside of the junction, between the platen heating surface tube bundle and the furnace ceiling tubes. The device also includes: a second thermal insulating layer, sleeved outside of the sealing box; a first thermal insulating layer, sleeved outside of the upper part of the platen heating surface tube bundle; and a non-metal expansion joint that is set between the first thermal insulating layer and the second thermal insulating layer. Patent number: WO2011069333 Inventors: Y. Liu, H. Tao and J. Liu Publication date: 16 June 2011
Seal unit incorporating sensor technology Applicant: AB SKF, Sweden This invention relates to a radial seal that is provided with one or more sensors for measuring a parameter (or parameters) of interest and/or for detecting leakage of a lubricant. Several sensor designs are described that may be moulded onto the air-side of the lip or on the flexible element area in the oil space. They may include an antenna for radio telemetry. Patent number: WO/2011/069519 Inventors: S. Ziegler, R. Herdier and F. de Wit Publication date: 16 June 2011
Sealing compounds with scavenger materials Applicant: ACTEGA DS GmbH, Germany This patent covers a non-polyvinyl-chloride (PVC) polymer compound for use in the manufacture of scavenger-containing seals for bottle screw caps. It is used, in particular, for oxygensensitive beverages and foodstuffs to ensure that these fillings remain unchanged for as long as possible. In particular, it is applicable to twist crown corks. According to the patent, the Shore A hardness of the polymer compound lies between 50 and 90, and its compression set falls between 30% and 90% after it has been left for 22 hours at 70ºC under a compression of 25%. Compression set tests were carried out according to the ASTM D395-97 (Method B) standard.
