The telephone cable seal with an interlocking segment to enable assembly without cutting the cable (WO/2009/055668).
casing of an aircraft gas turbine that are susceptible to relative axial and/or radial movement. The seal includes mounting flanges to match the ducting passages. It can be manufactured from a silicone material that may contain either a ceramic fibre or aramid fibre reinforcement. Publication number: WO/2009/056698 Inventor: S. Bunel Publication date: 7 May 2009
Seal with a large compression range Applicant: Aircelle, France This invention relates to a seal (1) designed to be inserted between a cowl (51) of a rear section of a nacelle and a turbojet of an aircraft propulsion unit. The seal (1) includes a hollow cylindrical portion (2) and at least one lip (3) extending radially from the cylindrical part (2). It is manufactured from an elastic material such as silicone, reinforced with glass or aramid fibres. Publication number: WO/2009/056699 Inventor: S. Bunel. Publication date: 7 May 2009
from parallel tubular sections. This patent also discusses the geometry of these tubular sections. Publication number: WO/2009/056700 Inventor: S. Bunel. Publication date: 7 May 2009
Gasket for an electric cable Applicant/Inventor: L. Kovacs, UK This invention relates to gaskets, but in particular to a gasket used in an electrical ‘back box’ in the wall of a building. The electrical cable trunking or apertures in a cavity wall are potentially weak points in providing fire protection and/or audio conduits for sound. The gasket is composed of a pad incorporating a composite of inert fibres along with an intumescent material portion. The pad is encapsulated with an insulating layer with a lateral portion to provide a location bias. The pad has a density to provide a desired level of acoustic attenuation and/ or damping when encapsulated in the insulat-
Applicant: Garlock Sealing Technologies Llc, USA Various gasket release agents and methods of providing and using these are discussed in this patent. The coating may be provided as a mixture of constituents, including hexagonal boron nitride. Other constituents may include a release agent and a binding material that enhances the adhesion of the release agent to the surfaces of the gasket body. A binding material may include, for example, organic or inorganic materials. Surfactants may be added to the gasket release agent dispersion in addition to binder materials and fillers.

Lubricating film Applicant: Sumitomo Metal Industries Ltd, Japan A lubricating film for oilfield tubular joints, which has excellent seizing resistance, gas tightness and rust-preventive properties, can prevent the yield of a screw-free metal contact part, even at a high torque. Free from any harmful heavy metal such as lead, this lubricant contains one of (or both) a rosin and calcium fluoride, a metallic soap, wax and a basic aromatic organic acid metal salt, and preferably further contains a lubricating powder, magnesium carbonate and/or carbohydrate, particularly cyclodextrin.

Double seal Applicant: Aircelle, France This invention concerns a seal that is designed to isolate an area in a propeller aircraft – particularly a turboprop – where there is the potential for a fire to start. It is a barrier seal between the nacelle and the turbine. The seals are composed of a matrix of silicone with a high loading of glass or carbon fibres to provide the fire resistance. To make the seal more flexible, and able to conform to the nacelle radius, it is made
