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.

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, a floating desorption station and at least one floating rope guide structure remote from the desorption station, the rope being in the form of a continuous loop extending between the desorption station through which the rope is advanced to remove adsorbed material and the floating rope guide structure which includes a hull and a guide means around which the rope is guided, said rope guide structure further comprising means mounted on said hull and adapted to being disposed in the liquid for directing the floating rope guide structure into a substantially predetermined position relative to the floating desorption station in response to the tension 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, said rope guide structure including steering means having a rudder which is positioned in response to deviations in the tension of the rope from a predetermined tension to steer the rope guide structure to at least tend to maintain the tension of the rope at said predetermined tension, the steering means including tension sensing means for providing an output in response to changes in tension in the rope at the rope guide structure, and means coupling the output of the sensinG means to the rudder, whereby the rudder steers the rope guide structure. 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, a floating desorption station and at least one floating rope guide structure including rope guide means comprising a guide pulley, the rope being in the form of a continuous loop extending between the desorption station through which the rope is advanced to remove adsorbed material and the floating rope guide structure at which the rope is guided around the guide pulley, said rope guide structure including means mounted on said hull and adapted to being disposed in the liquid for directing the floating rope guide structure into a substantially predetermined position relative to the floating desorption station in response to the tension of the rope during relative movement between the desorption station and the liquid to automatically 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, said rope guide structure including steering means having a rudder which is positioned in response to deviations in the tension of the rope from a predetermined tension so to steer the rope guide structure as to at least tend to maintain the tension of the rope at said predetermined tension, said steering means including resilient biasing means assoCiated with said pulley, said pulley being displaceable under the tension of the rope from the predetermined tension against the action of the resilient biasing means for controlling the rudder in dependence upon displacements of the pulley.
