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.
Claims4
A device suitable for recovering viscous material derived from petroleum comprises a plurality of pairs of blades, each blade being pivotally mounted at either end, and the pivots on at least one end being connected to an actuating rod or rods, so that the position of the pivots can be moved substantially at right angles to the width of the blades, the blades and rods being arranged to operate in such a manner that in a first position, the pairs of blades are in a vertical position, adjacent to one another but remote from other pairs, in a second position the blades form a series of V-shaped containers and in a third position the blades are again in vertical pairs, either in the same or in different pairs from the original position.
