PATENTS 14 Sealing Technology April 2014 Junction seals for a double door Applicant/Inventor: C. Glachet, France This invention relates to a double door struc- ture for leak-tight transfer action. The design described comprises a cell flange on which a cell door is fitted, and a container flange in which a container door is fitted. A first seal is fitted in the cell door, whilst a second seal is fitted in the container flange. At least one of these seals contains a cavity in which a quan- tity of air is trapped in a leak-tight manner. Patent number: WO/2013/167612 Publication date: 14 November 2013 Method for forming a seal on an opening of a vehicle body Applicant: CQLT Saargummi Technologies Sarl, Luxembourg This invention concerns a method for form- ing a seal, or cover, at an opening in the body of a vehicle. It is based on the reali- sation that it is not possible to achieve a secure connection between an elastomeric material and the support surface at a con- stant supply of adhesive. The support sur- face is preferably the rim of a vehicle door or other opening in the body. An extruded strand (1), made from an elastomer mate- rial, is applied (and adheres) to the body support surface. The support surface and/or a strand (1) surface is supplied with adhe- sive material (5) prior to the adhesion pro- cess. The supply of the adhesive material is controlled according to an adhesive material quantity requirement based on the strand length. This requirement changes in the longitudinal direction of the support surface because of the presence of depressions and/ or steps. Patent number: WO/2013/167257 Inventors: C. Kast, F. Michaely and K. Morawski Publication date: 14 November 2013 Flinger oil seal for a turbocharger Applicant: Borgwarner Inc, USA A compressor oil seal forms the subject of this patent. It discusses a thrust bearing adapted in such a way that it can be inserted into a turbocharger housing cavity – concen- tric with the turbocharger’s compressor-wheel shaft. An insert is adapted to enable it to be placed or fitted into the cavity adjacent to the thrust bearing. The latter and insert are configured so as to create an oil drain cav- ity between them. The seal also includes an oil flinger that has a flinger flange and from which extends a sleeve portion. The flange extends between the thrust bearing and the insert. A plurality of spiral vane segments are circumferentially spaced about the flinger flange. Each spiral vane segment extends from a first end to a second end. These seg- ments are disposed between the flinger flange and the insert. They may extend into a recess formed in the insert. This recess also may include at least one discharge port. Patent number: WO/2013/173054 Inventor: D.G. Grabowska Publication date: 21 November 2013 Jacketed resilient metal seal Applicant: Technetics Group Llc, USA A resilient metal seal is described that includes a polytetrafluoroethylene (PTFE) jacket or liner which aims to improve sealing performance and provide a near chemically inert surface to protect the seal from com- ing into contact with potentially damaging media. In some embodiments of this patent the seal possesses an E-shaped, U-shaped, C-shaped or V-shaped resilient metal struc- ture. A jacket made from PTFE, or a similar material, can be included on the interior or exterior surface of the seal. The jacket also may include a locking feature to prevent it from becoming dislodged from the metal seal. The accompanying figure shows the resilient metal seal (200) and exterior jacket (210) – primarily protecting the exterior surface of the resilient metal seal. The seal generally includes a plurality of apexes (201) where the metal bends to double over onto itself. Two divergent sealing arms (202) extend from one or more of these apexes. The sealing arms are divergent and biased away from each other such that compres- sion of the arms by the flanges (not shown) form the sealing surface. The jacket has a C-shape – and the depth and height is slightly greater than the depth and height of the resilient metal seal – (200) so that it can fit snugly around the seal. In particular, the jacket (210) has a wall (212) and two arms (214). These abut the sealing arms (202). As shown in the illustration the jacket protects the exterior surface as well as the upper and lower surfaces of the resilient metal seal. By covering these surfaces (the surfaces of the seal that will contact the flanges) it provides a layer of material that can conform to the surface of the flanges and creates a seal with enhanced properties.

Garrison Publication date: 21 November 2013 Seal-ring assemblies for use with rotary valves Applicant: Fisher Controls International Llc, USA Seal-ring assemblies for use in rotary valves and methods of manufacturing them form the subject of this patent. A seal-ring assembly is described that includes a ring-shaped seal that is to be fixed within the rotary valve. Its design results in sealing engagement of a control mem- ber with a flow-control aperture. The seal is compressed between two seal clamps by a force that is maintained by a plurality of fasteners. Patent number: WO/2013/173271 Inventors: T.R. Parrie, W.D. Hutchens and S.D. Cherry Publication date: 21 November 2013 Door sealing system Applicant: Planet Gdz Ag, Switzerland This invention relates to a door sealing sys- tem. It consists of component for sealing upper and lower sides of a building door leaf (T), and an air channel which enables – when the door seal is in the sealing position – air to circulate from a longitudinal side of the door seal to an opposite longitudinal side. This Patent WO/2013/167257 provides details of a system for forming a seal at an opening in the body of a vehicle. The process described is based on the realisation that it is not possible to achieve a secure connection between an elastomeric material and the support surface at a constant supply of adhesive material. Patent WO/2013/173467 provides details of embodiments of a resilient metal seal that includes a polytetrafluoroethylene jacket that is capable of improving sealing performance and providing a near chemically inert surface to protect the seal from coming into contact with potentially damaging media. 230 200 202 201 214 210 212
