Abstract: Vibration mounts (1) for automotive engines comprise spaced metal mounting brackets (2,4) are bonded to a MDI polyurethane cushioning medium (6) cast therebetween. The brackets (2,4) are marine grade stainless steel and are grit blasted before coating with a primer surfacing before the cushioning medium (6) is cast therebetween. After removal from a casting mould, the cushioning medium (6) in the brackets is subject to postcuring at 75°-150° C. for from 12-24 hours and thereafter is conditioned by storage at 15°-35° C. for a period of from 15-45 days to maximize the strength of the cushioning material.

Abstract: A coin pick up wheel for a coin receiving and validating apparatus, said pick up wheel comprising a disc-like body having a plurality of circumferentially spaced coin receiving recesses each recess including a chamfered edge portion extending at least partially about an upper edge thereof, said disc-like body having a central hub portion and an annular outer portion, said pick up wheel characterized in that said disc-like body is formed from a cross linked high molecular weight polyethylene polymer or co-polymer and further characterized in that said annular outer portion tapers convergently towards an outer edge of said disc-like body.

Abstract: A frangible boom assembly for vehicular tollway barriers is mounted to a boom actuating apparatus for pivotal movement between a barrier position transverse to a direction of traffic flow and a generally upright position to allow an authorised vehicle to pass. The frangible boom assembly is pivotally mounted to the actuation apparatus whereby in use, contact between a vehicle and the boom, when in a barrier position, causes said boom to swing away from the vehicle in the direction of traffic flow to reduce the possibility of damage to the boom member and/or the vehicle.
