Sealing element for an electrical connector
PATENTS Sealing strip for a motor vehicle’s window Applicant: Peugeot Citroën Automobiles Sa, France This invention relates to an assembly, including an outer window sealing strip, for a motor vehicle’s side door. It is intended to be attached along the upper edge of the outer panel of the side door. The assembly is characterised in that one end of the sealing strip includes an attachment that engages with a complementary attachment (provided on the trim) so as to be able to reference the end relative to the trim along the longitudinal, transverse and the vertical axes of the vehicle. The end of the outer sealing strip includes an elongate recess along its length that leads to the end point. The trim also has – in the attachment at end of the sealing strip – a tab that projects relative to an outer surface of the trim. This recess engages with the tab (of the trim). Patent number: WO/2011/135220 Inventors: G. Grunchec and X. Guilly Publication date: 3 November 2011
Piston ring Applicants: X. Li and S. Wang – China Inner and outer tooth-type piston rings for sealing a gas are described by this patent. The ring has a vertical stepped butt joint. A feature claimed is that the steps in the butt are located on an arc that is based on the same centre as the piston-ring radius. The actual application and whether or not this is a pure, gas piston ring are not obvious. Patent number: WO/2011/137747 Inventor: X. Li Publication date: 3 November 2011
Sealing element for an electrical connector Applicant: Tyco Electronics Amp GmbH, Germany This invention relates to a component for sealing electric cable glands on connectors. The sealing element has an elastically expandable inner sleeve. The gland has separate inner and outer sealing components so that the size of cable fitted has less of an effect on sealing the outside diameter of the gland, and permits a wide range of cable sizes to be used. Patent number: WO/2011/138182 Inventors: S. Hein, M. Szelag and A. Herrmann Publication date: 3 November 2011

EMI shielding gasket assembly Applicant: Molex Inc, USA This patent provides details of a gasket assembly for use in an angled electromagnetic interference (EMI) shielding cage. A problem associated with most connectors and their shielding cages is that they are mounted perpendicular to the face plate so that when plug connectors are inserted (in a ‘‘straight-on’’ manner) into the cages – to mate with the internal connectors – the cables extend straight outwards from the device. The gasket frame described has guides disposed on one side of it that make contact with the cage and orient it at an angle to the gasket frame. The gasket frame further includes at least a pair of clips that retain a conductive, compressible component in place around the frame opening. Patent number: WO/2011/140064 Inventors: D.P. Cantrell and K. Janota Publication date: 10 November 2011
A cryo-preservation device for storing reproductive biological material forms the subject of this patent. A concentric tube-shaped device is described. This may be slid together once a sample has been added. Two or more ‘‘bulge portions’’, or a flared portion, create the seal between the respective tubes. Patent number: WO/2011/140299 Publication date: 10 November 2011
Vacuum dynamic seal Applicant: Dongguan Anwell Digital Machinery Co Ltd, China A device for transmitting an optically encoded rotary signal into a vacuum chamber forms the subject of this patent. The details of the actual seal are not described in the English abstract. Patent number: WO/2011/137689 Inventors: M. Yeung, Y. Wang, H. Liu, K. Fan, Y. Wang, M. Wang >`Ê°Ê< >} Publication date: 10 November 2011
Tunable floating seal insert Applicant: Cameron International Corp, USA The seal detailed by this patent is part of an assembly used in an oil well to attenuate shock waves in the system. An installation is provided in which a floating restrictor device may be fitted – with the bore of the restrictor selected to achieve the flow control that is required. The restrictor is allowed to float axially over a limited stroke and is sealed on the outside diameter by the seal discussed, which is described as an O-ring. Patent number: WO/2011/139399 Inventor: J. Kotrla Publication date: 10 November 2011
Brush ring seal Applicant: Elliott Co, USA The brush seal described by this patent is manufactured in segments and retained as a unit by a garter spring. It is designed to replace carbon segmented rings used in steam turbines. The rear face of the brush seal carrier is coated with an anti-friction coating. This enables movement of the brush ring seal device within its packing case. Patent number: WO/2011/139741 Inventor: M.A. Mindock (III) Publication date: 10 November 2011
Carrier incorporating a seal for cryogenic storage applications Applicants/Inventors: B.K. Butler, T.W. Wingler, J.M. Carlson and S.K. Philhower – USA
Rolling bearing with integrated seal Applicant: Schaeffler Technologies Ag & Co Kg, Germany This invention relates to a rolling bearing (2) containing an integrated seal which consists of an annular sealing disc (10) that has elastic properties, and which is inserted, with a first edge (14), into a retaining groove (16) in one (4) of the bearing rings, while the other second edge (18) engages slidably in a sealing groove arrangement (20) on the other bearing ring (6). In order to protect the sealing disc (10) against deformation, while at the same time retaining the elastic properties – enabling it (the sealing disc), in the case of self-aligning bearings, to follow a tilting motion of the outer bearing ring and optionally allow for axial play and/or radial play of the bearing rings relative to each other – it is reinforced and stiffened at an edge region (b) adjacent to the first edge (14) by a
This seal – for self-aligning bearings – has a structure that combines both a reinforced section, to resist deformation, and a flexible section to enable relative movement of the inner and outer race. Patent WO/2011/138107 has further details.
