Sealing device for universal joint
PATENTS Filter element having V-seal Applicant: Mann+Hummel GmbH, Germany A replaceable filter element that is fitted with a seal moulded on a cylindrical collar at the base of the element. The seal has radial sealing beads and a more extended seal lip that contacts the radius on the base of the filter housing. Publication number: WO/2009/047204 Inventors: O. Steins et al. Publication date: 16 April 2009
Filter element having serrated seal Applicant: Mann+Hummel GmbH, Germany This version of a filter seal has a U section seal with sealing beads moulded around the two inner surfaces of the U section. When the filter body is assembled these beads seal either side of a cylindrical collar in the end of the filter body housing. Publication number: WO/2009/047205 Inventors: O. Steins et al. Publication date: 16 April 2009
in excess of the combustion chamber pressure in the sealing gas channel during the firing and power strokes of the engine. Publication number: WO/2009/047566 Publication date: 16 April 2009
Mat seal joint for electrical connector Applicant: FCI; France A mat seal joint for an electrical connector is designed particularly for automotive applications. Since, in most connectors, not all the channels are meant to receive an electrical connection member, membranes are provided in the channels to avoid the need for separate plugs to seal those of the channels which are unused. The membranes remain not pierced in the unused channels, thus avoiding the sealing of the joint to be impaired. This design provides a leakage channel which provides an indication that an unused membrane has been damaged and it will fail a factory sealability test. Publication number: WO/2009/047589 Inventors: O. Yahya et al. Publication date: 16 April 2009
Shaft seal for down-hole tools Applicant: Caledyne Ltd. UK A dynamic seal for either reciprocating or rotary applications down-hole that is designed so that the seal is only actuated when required, which may be a small proportion of the installed lifetime. A moveable housing (11) can slide relative to the seal (10). This axial movement can change from a non-energised seal 10A to compress the seal to an energised position 10B. The switching means may be either mechanical or hydraulic. The spring bias illustrated will provide a failsafe seal energisation, in the event of system failure. The system can be designed to provide either power to energise or de-energise as required. The seals may be polymeric or other suitable materials. Publication number: WO/2009/047552 Inventor: M. Murray Publication date: 16 April 2009
Seal for a rotary valve for an internal combustion engine Applicant/Inventor: G. McNally, UK This rotary valve design comprises a cylindrical valve that extends the length of the cylinder head. It has a gas channel surrounding the ports which can pressurize the seal to provide

Sealing device for universal joint Applicant: NOK Corporation, Japan A sealing for a universal joint has an L section metal casing and a series of seal lips. These include radial lips to seal on the inside diameter of the outer ring of the needle roller bearing and an axial lip to seal on the boss of the spider. The design permits fitting without damage to the seal lips and is effective in muddy water conditions. Publication number: WO/2009/047991 Inventor: N. Kobayashi Publication date: 16 April 2009
The down-hole seal that can be energised by activating a sliding housing, WO/2009/047552.
Composite multilayer seal for PEM fuel cell
Washing machine having a gasket
Applicant: Ames Rubber Corporation, USA A composite seal having a multilayer elastomeric construction is applied by cure in place or mould in place methods. It comprises a soft and compliant silicone layer coated with a protective fluoroelastomer layer. The seal is moulded directly onto the fuel cell components. Publication number: WO/2009/048991 Inventors: J.W. Brush et al. Publication date: 16 April 2009
Applicant: BSH Bosch und Siemens Hausgeräte GmbH, Germany The purpose of this invention is to mitigate the varying gap between the tub and the drum while the washing machine is in operation. A flexible seal of varying cross section is provided to absorb the movements. A shock absorber may also be fitted. Publication number: WO/2009/050095 Inventors: U. Ackermann et al.
