Abstract: A carrier for carrying rectangular items is disclosed, the carrier including: a generally elongate handle portion which can be grasped by a user; holding portions are provided at either end of the handle portion; each holding portion includes at least one aperture arranged to receive and support respective opposite corners of an item so that the item may be carried by way of the handle portion.

Abstract: The amount of limonene produced during pyrolysis of scrap tire carcass or polyisoprene rubber can be increased by decreasing residence time of the isoprene gas produced during the thermal degradation of polyisoprene rubber in the high temperature reactor region of an oven. This is achieved by using a novel oven design which permits rapid expansion of the isoprene gas away from the high temperature reactor region of the oven to a cooler region where the gas forms limonene and condenses. This pyrolysis method also decreases the amount of soot produced while increasing the amount of limonene produced. Furthermore, this system readily enables separation of the solid, liquid and gas phases produced during pyrolysis.
