ABSTRACT:
The present disclosure is directed to material recovery apparatus comprising a rope of an adsorbent material arranged for floating on the surface of a liquid contaminated by a contaminating material preferentially adsorbed by the rope, the rope being in the form of a continuous loop extending between a desorption station through which the rope is advanced to remove adsorbed material and a floating rope guide structure at which the rope is guided around guide means. The rope guide structure is so constructed as automatically under the pull of the rope during relative movement between the desorption station and the liquid to bring the rope into a disposition in which a part at least of the length thereof has a component of motion over the surface of the liquid and relative thereto which is transverse to the longitudinal direction of the said part. The rope guide structure furthermore includes steering means responsive to deviations in the tension of the rope from a predetermined tension so to steer the rope guide structure as to maintain or tend to maintain the tension of the rope at said predetermined tension.
