Seal sub-system
PATENTS Improved rotating sleeve engine hydrodynamic seal Applicant: Rotating Sleeve Engine Technologies Inc, USA An improved sealing system for a poppet valve, rotating sleeve internal combustion engine with rotating liners has been developed. A hydrodynamic face seal assembly is described that includes a spring preloaded assembly – providing uniform loading on a primary sealing ring. A secondary seal is located between the primary sealing ring and the cylinder head. Hydrodynamic face-seal features are created either on the mating face of the primary sealing ring or on the annular face of the rotating liner. These features include an inner sealing zone and an outer loading zone with a plurality of hydrodynamic lift pads, and dam features that create converging surfaces. A lubricant, applied to the annular face of the rotating liner, can be maintained between the primary sealing ring mating face and the rotating liner. Patent number: WO/2013/152214 Inventor: D. Dardalis Publication date: 10 October 2013
Device for sealing between the coaxial shafts of a turbo-machine Applicant: SNECMA, France This invention relates to a device for sealing between the coaxial shafts of a turbo-machine. It comprises an annular structure that is able to perform sealing action when in contact with the outer shaft. A characteristic of this device is that it incorporates a means of lubrication that can be applied to the region of contact between the annular seal and outer shaft. Patent number: WO/2013/150198 Inventors: A.J.-M. Pierrot and S.R. Morreale Publication date: 10 October 2013
Watertight seal for an electrical system Applicant: Continental Automotive GmbH, Germany The objective of this invention is to create an electrically conductive connection (sensor contact) between an electronic control unit circuit board and motor contacts that is waterproof. A watertight and tolerance-insensitive signal contacting sealing device is described. It is designed to create a sealed electrical contact between two electrical components. A body seal (containing at least one passage) has an opening arranged between the electrical components. It is characterised by at least one electrically conductive and elastically deformable conducting unit that 12

is arranged in the passage, sealing it off. Patent number: WO/2013/150104 Inventors: A. Bermel, R. Jentsch, U. Kirchhoff, K.-P. Rathmann and H. Zuber Publication date: 10 October 2013
Seal sub-system Applicant: Cameron International Corp, USA A seal sub-system is described for the connection of fluid lines, including first and second lines, each with a terminal end. It has been developed for use in the offshore oil and gas industry. The seal sub-system includes an inner channel and first and second pin-ends. One pin-end is insertable into the fluid-line terminal end. The other pin-end extends from the fluidline terminal end. A seal is formed between the seal sub and the inner diameter of the first fluid-line terminal end. The extending pin-end is configured to be inserted into the terminal end of the second fluid-line in order to establish a sealed fluid connection between the first and second fluid-lines.

Energised bushing seal
optimise the shape of the seal. It is formed into a circular structure with a through-hole (110), the shape and size of an outer circumferential surface (120) of which follow standards, and the thickness from the outer circumferential surface to an inner circumferential surface (130) is controlled in the circumferential direction of a vertical cross-section so as to increase resilience. The thickness gradually decreases as it circumferentially approaches upper and lower portions from both sides, in the circumferential direction of the vertical cross-section. Raised protrusions (140) project towards the centre of the vertical cross-section at the inner circumferential surface (130) of the upper and lower portions, and grooves (141) are formed at both sides of the protrusions (140).

Well-site connector with floating seal member Applicant: National Oilwell Varco Lp, USA A connector for joining components used by a well-site forms the subject of this patent. The well-site has a wellbore extending into a subsurface formation. The connector includes a body component and a floatable seal. The body has
Applicant: Array Holdings Inc, USA This invention generally relates to bushings. More specifically, it covers bushings used in well heads within a casing or tubing spool in which mechanical seals are used. The design detailed by this patent eliminates the need for two ports through which sealing media is injected to energise mechanical seals on oilfield casing and/or tubing. Instead it is injected through one port. This enables the media to energise the seals to a specific pressure against the casing or tubing OD to contain the pressure of the oil or gas well. This modification results in time savings in the field during the installation of equipment. It also avoids the problem of locating two ports (one for each of the seals) when the flange thickness is insufficient to support two ports. Patent number: WO/2013/152033 Inventor: J.

Highly resilient metal O-ring seal Applicant: Korea Basic Science Institute, Korea This patent provides details of a metal O-ring seal (100). The objective of this invention is to increase the flexibility of the structure and
Patent WO/2013/151358 provides details of an O-ring seal with an optimised geometry, which enables it to be used in applications involving harsh operating conditions.
