20090050812 | Detection of Ionising Radiation - A detector for detecting ionising radiation comprises a scintillator | 02-26-2009 |
20090121121 | Fibre Structure for the Identification of Defects In the Structure - This invention is concerned with means for detecting potential fracturing, such as stress fractures, or damage to, a fibre based structure, by incorporating either hollow fibres containing coloured fluids, or solid fibres, or hollow fibres containing coloured fluids or fluids, which are capable of changing their visual appearance when exposed to external forces, and/or by incorporating fibres within the structure which can change a property such as electrical resistance, capacitance or inductance so that there is an indication whenever and wherever and the extent when a fracture occurs. Where coloured fluids are used, detection is by leakage of the fluid around the fracture. Where colour changing fluids are employed, detection is by observation of change of colour of the fluid. Different fluids can be used for different levels in the strata of tubes in the structure and where these are embedded within the structure, they can be observed where the fibres emanate from the body of the structure. Where fibres are incorporated into the structure that rely on electrical properties to sense a fracture, these fibres may be solid and formed from electrically conductive material and may be coated with such material. Alternatively, though used together with solid fibres, hollow fibres may be used where those hollow fibres contain and/or are coated with electrically conductive material. Appropriate detector means are associated with these fibres to detect the occurrence of a fracture. | 05-14-2009 |
20090208684 | Self-Reparing Structure - This invention relates to a structure which comprises hollow and solid fibre material embedded in a resin matrix where a repair facility is provided for repairing fractures in the fibres and in the resin matrix by the use of curable two-part adhesive compositions in some of the fibres of the structure. Dedicated hollow fibres carry separate parts of the adhesive compositions under pressure so that in the event of fracture of any fibres, the component parts of the adhesive composition can combine and cure in situ to fill and “heal” the fracture. The invention has particular but not exclusive application to in “flight” repair of aircraft components which are formed by such structures, and can also be used in the manufacture of fabric materials. | 08-20-2009 |
