Abstract
A device suitable for recovering viscous material derived from petroleum, comprises a plurality of pairs of blades (1 and 2, 3 and 4, 5 and 6) each blade (1, 2, 3, 4, 5, 6) being pivotally mounted at either end, and the pivots on at least one end being connected to an actuating rod or rods, (11, 12, 13, 14). The blades and rods are arranged so that in a first position the pairs of blades are vertical, in a second position they form V-shaped containers (21, 23, 25) and in a third position the blades are again in pairs, which are either the same or different pairs from the original position.
