FEATURE/PATENTS to ozone, debris and ageing resistance over long operating periods. A method for vulcanising the end faces of profiled strands enables the economical production of sealing rings of any diameter required.
Guaranteed quality Schaeffler recently introduced a Wind Power Standard (WPOS) for its bearings for wind power applications. This standard for products and processes means that the company is ensuring the outstanding quality and reliability of its bearings and offering customers the same high standards of quality as it is already successfully providing in the automotive and aerospace industries.
PATENTS Combustor seal system for a gas turbine engine Applicant: United Technologies Corp, USA A system for providing a seal between a combustor and a turbine vane is described. It includes a flange configured to extend radially from the combustor and seal. The flange includes a surface configured to face, in an axial direction, towards a surface of the vane. The seal is configured to be axially loaded between the flange surface and the surface of the vane. Patent number: WO/2014/052949 Inventors: K.J. Low and J. Wong Publication date: 3 April 2014
Connection system and method Applicant: Entegris Inc, USA This disclosure relates to a connection used in a system that conveys fluids. In particular, some embodiments of this invention relate to connections for use with fluids used in semiconductor manufacturing processes. The system described uses a nut that seals fluid fittings. By making use of multi-start threads embedded in the nut, a rotation of less than 360° is required. According to one embodiment, the connection nut creates at least 360° of “threaded engagement” with a rotation of less than 360°. Other embodiments provide details of connection systems that can seal multiple ports simultaneously. Patent number: WO/2014/055452 Inventors: M. Laverdiere, J.P. Puglia, B.M.P. Lee, K. Madhavaram, C.W. Martland, D. Menn and J.K. Niermeyer Publication date: 10 April 2014 12
Sealing Technology
In all phases of product development, Schaeffler focuses on very high quality. An example of this is in the requirements for material approval. Even during the development process, these ensure that all components, such as greases and seal materials, are compatible with one another, the required performance characteristics are reliably achieved and the guidelines relating to prohibited substances are observed. All suppliers must fulfil stringent quality requirements. The seals are checked and approved by Schaeffler in accordance with stringent guidelines before they are fitted. These standards lead to optimally matched bearing units comprising bearings, lubricant and sealing systems.
Advantages of the optimised bearing seal include: UÊ UÊ UÊ UÊ

Downhole cable termination system Applicant: Siemens Aktiengesellschaft, Germany This patent covers a downhole apparatus for terminating a cable. The cable extends downhole, from a tubing hanger, to electrical equipment. The apparatus described comprises: a first seal, for sealing the apparatus uphole of the first seal from the downhole environment; a second seal for sealing the apparatus uphole of the second seal from the downhole environment; and a sleeve, arranged around the cable and attached to it. This sleeve provides a radially outward facing engagement portion for the first seal and a radially inward facing engagement portion for the second seal. The sleeve has two parts – the first is attached to the cable and provides the radially outward facing engagement portion, whilst the second part (separate from the first) provides the radially inward facing engagement portion. The sleeve is arranged such that when the apparatus is assembled on the cable the first and second parts are joined together. Patent number: WO/2014/053259 Inventors: C. Burrow and M. Simmonds Publication date: 10 April 2014
Gasket Applicants: Uchiyama Manufacturing Corp, and Toyota Jidosha Kabushiki Kaisha – Japan A gasket (10) forms the subject of this patent. It has a planar core material (11) with an opening (11a); an inner seal part (12), composed of an elastic material and formed along the inner peripheral part of the opening (11a); and an outer seal part (13) that consists of an elastic material and formed along the outer peripheral part of the planar core material (11). The gasket (10) is characterised by the planar core material (11), which is provided with: seal-forming thin

parts (11c & 11d) for forming the inner seal part and the outer seal part on the inner peripheral part and the outer peripheral part; and a “deformation-easing” part (15) that makes the deformation of the planar core material (11), between the inner and outer seal parts (12 & 13), easier.

Sealing device Applicant: NOK Corp, Japan The main objective of this invention is to create a sealing device that is equipped with a resin seal-ring, a support ring manufactured from a hard material, such as metal, and a spring means. It is designed and constructed so that a tapered surface, provided on the support ring, presses against the seal ring in such a way that a gap does not easily form between the pressing surface and the seal ring, which means pressure resistance and sealing performance are improved. To achieve this objective, this sealing device – which is located in a mounting groove provided in one of two members that move relative to one another, and which makes close contact with the other member and the side walls of the mounting groove, thereby providing a seal between the two members – has: a seal ring; a support ring equipped with a tapered pressing surface that
