Abstract: The links, which are hinged together constituting the bracelet, comprise a core (2) formed from machinable metal and provided with hinges (14), sandwiched between two protection parts (4, 6). The protection parts are maintained in place by at least one stud (10) fixed to one of the protection parts (6) and extending through piercings (12, 13) formed respectively in the core (2) and in the other protection part (4), the stud (10) being retained in said piercings by a swaged rivet head at its distal end (10a). Two lateral portions (8) of one of the protection parts (6) extend opposite the lateral faces of the link.

Abstract: An arrangement for venting a destructive internal pressure generated by an explosion within an enclosure, such as aircraft fuselage. The arrangement includes a pressure venting device for venting an exterior boundary, fuselage skin, of the enclosure; and an explosion sensitive sensor located within the enclosure. In response to an explosion within the enclosure, the sensor will send a signal to the pressure venting device. The pressure venting device creates a pressure relieving vent in the exterior boundary in advance of build up of destructive internal pressure within the enclosure.

Abstract: A method of progressively molding and curing/homogenising a composite material component assembly including a skin panel and a series of spaced structurally reinforcing members therefor. The method includes the steps of placing a composite material layer (18) on support (13), clamping same to the support by a mold including first and second tools (14/16), the second tool being separated from the first tool by a pre-determined amount, slidably moving the second tool (16) towards the first tool (14) to cause the material to fold in an upwards direction until clamped between datum faces (15, 17) of the tools to define the structural member, heating the support (13) and tools (14, 16) to cure/homogenise the skin panel and structural members, then slidably moving the component along the support (13) a pre-determined amount to draw a further quantity of composite material layer (18) from a source and repositioning the tools (14, 16) for further processing of the material.
