Abstract: The invention relates to the use of particles of sulfated lime (containing up to 80% CaSO.sub.4) as a polymer filler which can be derived from dry desulfurization of flue gas. Such sulfated lime can advantageously be incorporated into an elastomer such as ethylene propylene diene monomer rubber (EPDM) or styrene-butadiene rubber (SBR).

Abstract: A powered vehicle for loading, transporting and unloading heaped materials comprises a chassis having a first fixed part mounted on running gear and a second movable part pivotally mounted on the front of the fixed part which is substantially vertically aligned with the front axis of rotation of the running gear, the front of the movable part projecting beyond the front of the fixed part and having pivotally mounted on it a skip. The skip is moved between loading, transportation and unloading positions by two elements, one of which bears on the fixed and movable chassis parts for pivoting the movable chassis part relative to the fixed chassis part and the other of which bears on the movable chassis part and the skip for pivoting the skip relative to the movable chassis part.
