  • Patent number: 10611930
    Abstract: The invention relates to methods of bonding and a conductively bonded joint, provided by high loadings of conductively coated nano scale particulate fillers in a conductive adhesive in combination with a conductive intermediary structure, more particularly to a lightning strike resilient bonded joint between fibre reinforced polymer composites. A method of joining a first fibre reinforced polymer composite surface and a second fibre reinforced polymer composite surface, comprising the steps of providing a conductive intermediary structure between said first and second surfaces, filling the void between said surfaces and enveloping said intermediary structure with a conductive adhesive, curing the conductive adhesive to form a bonded first and second surface. A conductive adhesive comprising a curable binder and a high aspect ratio nanoscale carbon particulate filler present in the range of from 0.1 to 40% wt, wherein said particulate filler comprises a metal coating.

  • Patent number: 9952137
    Abstract: A sensor (1) and a method of manufacturing the sensor (1), the sensor (1) including a number of metallic strips (5,6,7) mounted on a non-conducting substrate (4) and a module (3) for forming electrical connections to the strips (5,6,7) whereby to enable communication between the strips (5,6,7) and monitoring equipment for the sensor (4), the module including a number of wire connections (16), the method including the steps of encapsulating the wire connections within a flexible chemical and heat resistant sealing compound, and subsequently, encapsulating the flexible sealing compound within a second sealing compound (34) by an injection molding process.

  • Patent number: 8894925
    Abstract: A method and device are provided for treating flammable materials, fuels for example, by irradiation of the materials with ultra-violet radiation. In one embodiment, the apparatus suited for connection to a fuel line includes a body with centrally-formed duct and UV light sources mounted outside of the duct at upper and lower sides. It is to be appreciated that the invention has utility for many different fuel system applications, for example in aircraft, boats and in other motive vehicles. Further, the device can be conveniently mounted, if desired, on different fuel platforms including on bowsers.

  • Patent number: 8596462
    Abstract: A separator is disclosed for separating particles of at least first and second mass/size ranges from an ambient fluid (e.g. gaseous) medium in which they are present, particles of the first range being of generally larger size/mass than particles of the second range. The separator is especially designed for use in an air monitoring device which is designed for rapid detection of micro-organisms such as bacteria, viruses, pathogens and the like, and is designed to be portable so that it can be readily and rapidly deployed in both civilian and military environments and can be used indoors and outdoors; it can also be designed for personal use.

  • Publication number: 20110226675
    Abstract: A particle separator stage in a particle separator includes an inflow passage of generally annular, axially facing form. In other embodiments, an asymmetric geometry is disclosed in which the major flow is taken from one side only. These features combine to allow compact, multi-stage separators to be produced. Also disclosed an arrangement in which the flow rate at a location within the separator stage is measured and used to control the flow rate there or elsewhere.
