Sealant and transition seal bodyfor protecting a down-hole cable
PATENTS Tank cover for a petrol engine Applicant: Chongqing Zongshen General Power Machine Co Ltd, China A tank cover for a petrol engine forms the subject of this patent. It comprises an outer casing; an inner casing; and a seal cap, located on an upper end-surface of the inner casing. The outer casing is connected to the inner casing through ratchet and limiting mechanisms. A first baffle plate and a second baffle plate are disposed in an upper chamber of the inner casing to divide it into a first adsorption cavity, a second adsorption cavity and a third adsorption cavity (from the outside inwards). Carbon particles are contained by the first and second adsorption cavities, and foam is placed in the third one. A first vent hole, linking the third adsorption cavity to the tank, is located in the bottom of the first baffle plate. A second vent hole, linking the first adsorption cavity to the outside atmosphere, is located in the bottom of the first adsorption cavity. The purpose of this cover is to prevent evaporated gas, from the fuel, from being discharged directly into the surrounding environment. Patent number: WO/2012/163077 Inventors: Y. Wang, H. Li and J. Pei Publication date: 6 December 2012
perforated and moves (in the direction shown (25) in the accompanying figure) within a machine which is used to make paper, tissue or cardboard. At least one sealing element (10) is described. It lies opposite the moving surface (4) and is arranged in a receptacle (8) that can be moved to change the format of the negative or positive pressure zone (7). To maintain the adjustability of the receptacle – in order to position the sealing element – a signal transmitter (11) is connected directly (or indirectly) to the sealing element. A transmitted signal is received on the side of the moving surface (4) that faces away from the sealing element (10). Patent number: WO/2012/168034 Inventors: P. Schotge, S. Berger, K. Hermann, A. Schäfer and D. Gronych Publication date: 13 December 2012
Seal assembly Applicant: Voith Patent GmbH, Germany This invention relates to an assembly (1) for sealing at least one negative or positive pressure zone, which adjoins a surface (4) that is

Applicant: Quick Connectors Inc, USA This patent relates to a new and an improved method of sealing a continuous cable – through a well-head – for providing power to equipment, such as a submersible pump, or a heating system, that is in use underground. Specifically, applicants claim a well-head penetrator system that seals against excessive pressure and high temperatures and, thereby, maintains the integrity of the electrical cable system. A combination of elastomeric and epoxy seals are used as the primary sealing agents. The use of epoxy – completely surrounding the transition seal body within the penetrator mandrel – permits safe and effective field installation of continuous electrical conductors from the well-bore through a pressure sealing well-head to the surface. According to the patent, this approach provides better protection than that provided by a mechanical connection. Patent number: WO/2012/170894 Inventors: T.D. Emerson, J.L. Reeves, L. Cantu and M. Daugherty Publication date: 13 December 2012
Improved seal
Expandable seal with conforming ribs Applicant: Baker Hughes Inc, USA The expandable seal detailed by this patent uses one or more conforming ribs to create a seal with a well surface. The ribs consists of a core material either capped, partially covered by (or entirely covered by) a ring. The ring is formed from metal that is softer than the metallic core material of each rib. Suitable metals for producing this ring include copper. Disposed adjacent to the ring is one or more sealing elements. By moving each ring into the sealing surface during expansion of the seal, extrusion gaps are closed between the internal surface of the casing and the expanded tubular member ribs. The rings better conform to the sealing surface of the casing, and as a result create an effective seal between the surface and each of the sealing elements.

Sealant and transition seal body for protecting a down-hole cable
Patent WO/2012/168034 provides details of a seal assembly for machinery which is used to make paper, tissue or cardboard. It is used to seal two pressurised zones.
Brush-seal cover Applicant: Sealeze – a unit of Jason Inc – USA This invention concerns a brush-seal cover assembly. According to the patent, it not only covers and protects the bristles of the brush – which is part of the brush seal assembly attached to a piece of equipment – while maintenance work is carried out, but it also protects the brush holder whether or not a brush is installed. In use it maintains structural integrity and preserves brush-seal location, which helps to maintain brush-seal integrity once the equipment starts operating again (when maintenance has been completed). The brush-seal cover assembly constructed in accordance with this patent includes a brush cover that has a shroud which encloses the seal brush. Patent number: WO/2012/170750 Inventors: R.

Applicant: Aktiebolaget SKF, Sweden The main objective of this invention is to create an enhanced seal. The aim is to produce a seal that has a low-friction surface and is hard wearing under normal operating conditions. This patent provides details of an elastomeric lip seal. It has a contact surface which has been coated with a compound that consists of a polymerised diallylamide or diallylamine. Patent number: WO/2012/168354 Inventor: S. Barbera Publication date: 13 December 2012
Seal ring Applicant: Kabushiki Kaisha Riken, Japan The objective of this invention is to produce a seal ring which has excellent dimensional stability and fit, with respect to an opposing member; is able to effectively prevent leakage of oil, even at very low hydraulic pressure; and has excellent sliding properties. The seal ring described is produced from a resin composition containing polyphthalamide and at least one species selected from among an elastomer, a cross-linked rubber and a dynamically cross-linked resin. To the resin composition also may be added at least one type of filler material selected from among carbon, alumina, potassium titanate, boron
