Abstract: There is provided a modular storage rack comprising flat panels each comprising one or more flat segments and cross panels each comprising one or more cross segments. Each flat segment comprises a slit extending partway through it. Each cross segment comprises: a first and a second planar portion each terminating in a first and second lip respectively. The first lip faces the second lip, and they define a slot for receiving the flat segment. Each cross segment also comprises an island joining the first planar portion to the second planar portion, the island disposed in the slot and between the first and second lips. The island is configured to be received in the slit. Each flat segment is matingly connected to a corresponding cross segment such that the flat segment is received in the corresponding slot and the corresponding island is received in the corresponding slit.

Abstract: A flexible annular coupling made of composite material and an even number of relatively thicker fixing portions (10) spaced apart circumferentially around the coupling for connection to two rotary members to be coupled by the coupling and a flexible leaf (11) extending lengthwise between each two adjacent fixing portions. Each leaf includes a relatively thinner central part (11a) and a transition portion (13) of gradually increasing thickness between the ends of the central part and the thicker fixing portions. The coupling is constructed such that the central part (11a) of at least each circumferentially alternate leaf will always be displaced axially in the same predetermined direction (A) transverse to its length when the leaf is caused to buckle by compressive force(s) acting between the fixing portions at the ends of the leaf. The displacement may be obtained by curving the central part, by suitably shaping the transitional portions or by making the central part of two layers of different stiffness.

Abstract: A joint disc made of a fiber composite material with a plurality of flexible leaf elements and a plurality of angular fixing elements which are composed of laminations of fiber composite material, with the leaf elements, at each of their ends, having an increasing thickness extending at least over 10% of their length.

Abstract: Assembly comprising a spring in the form of a zig-zag strip of fibre reinforced plastics material with limbs (10-16) connected by reflex portions (17,22), wherein end limbs (10,16) of the spring are mounted at an attitude they would adopt when loaded if they were pin-jointed so as to be free to move as the spring is loaded so that over-stressing of the reflex portions (18,21) of the spring is thereby avoided when the spring is loaded. In modifications of the invention, a spring end limb (39) may be progressively engaged by a surface (42) of a mounting to be supported at a range of attitudes corresponding to a range of spring loads; or a spring mounting may be associated with pivotable members so that end limbs of the spring move arcuately therewith and change their relative attitude as if they were pin-jointed.

Abstract: A suspension for a pair of wheels of a motor vehicle, comprising a spring (10,30) extending tranversely of the vehicle and supported by two mountings (11,12) spaced between the spring ends and which ends are connected, directly or indirectly, to wheel carrier members, wherein the spring has a portion (22,24) displaced out of the general line of adjacent parts of the spring to give a clearance from a part of the vehicle. The displaced part of the spring may be the entire central portion (40,50,60,100) thereof between its mountings (45,46,101) and end portions of the spring may be inclined to such central portion, so that the space directly between the wheels is clear of suspension parts.
