Abstract
Abstract An apparatus for the recovery of oils or other similar pollutants floating on bodies of water, including the open seas, and a related support vessel, including a conveying apparatus and a recovery unit for the floating oils which both float autonomously and independently of each other and from the support vessel. The conveying apparatus includes two self-buoyant arms disposed in the shape of a V, flexible with respect to a vertical plane to ride the waves, and towed by the support vessel by means of two swinging forks. The recovery unit comprises two large rotating, horizontal axis drums, surrounded on the lateral and the rear sides by an apron to contain the floating oils, and is towed by the support vessel to float independently. Pumping means for the recovered oils is provided.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
240 words
An apparatus for the recovery of fluid substances or the like floating on water and even in open seas, comprising: (a) a conveying apparatus adapted to be moved on the water by a support vessel, the conveying apparatus including two flexible floating arms which are more flexible in a vertical plane than in a longitudinal plane, the floating arms being linked to each other in their rear parts by a rod and assuming the shape of a V; (b) swinging forks for connecting the conveying apparatus to the support vessel, the swinging forks allowing the conveying apparatus and the support vessel to float independently of each other; (c) a self-floating recovery unit adapted to be moved on the water by said support vessel, the recovery unit including a rotating horizontal drum for recovery of said floating fluid substances, an apron around the sides and rear of the drum for containing a layer of the floating fluid substances directed towards the drum by the floating arms of the conveying apparatus, and means for removing fluid substances from the drum after being recovered by the drum; and (d) means for connecting the recovery unit to the support vessel, the means including a swinging fork which allows the recovery unit and the support vessel to float independently of each other, and the means further including a hinge which allows the recovery unit to rotate about its longitudinal axis independently of the support vessel.
Claim 2
Independent Claim
240 words
An apparatus for the recovery of fluid substances or the like floating on water and even in open seas, comprising: (a) a conveying apparatus adapted to be moved on the water by a support vessel, the conveying apparatus including two flexible floating arms which are more flexible in a vertical plane than in a longitudinal plane, the floating arms being linked to each other in their rear parts by a rod and assuming the shape of a V; (b) swinging forks for connecting the conveying apparatus to the support vessel, the swinging forks allowing the conveying apparatus and the support vessel to float independently of each other; (c) a self-floating recovery unit adapted to be moved on the water by said support vessel, the recovery unit including a rotating horizontal drum for recovery of said floating fluid substances, an apron around the sides and rear of the drum for containing a layer of the floating fluid substances directed towards the drum by the floating arms of the conveying apparatus, and means for removing fluid substances from the drum after being recovered by the drum; and (d) means for connecting the recovery unit to the support vessel, the means including a swinging fork which allows the recovery unit and the support vessel to float independently of each other, and the means further including a hinge which allows the recovery unit to rotate about its longitudinal axis independently of the support vessel.
Claim 3
Dependent Claim
28 words
An apparatus according to claim 1, wherein the flexible arms on the conveying apparatus are more flexible at their tip in a vertical plane than at their base.
Claim 4
Dependent Claim
42 words
An apparatus according to claim 1, in which the recovery unit includes two hollow rotating drums, which contribute to the buoyancy of the recovery unit, and wherein the apron includes collecting well means to receive the fluid substances recovered by the drums.
Claim 5
Dependent Claim
45 words
Apparatus as in claim 3 wherein the collecting well means includes two wells, one in each side of the apron, the wells being connected to each other by a horizontal pipe, which is connected to a pumping unit to pump away the recovered fluid substances.
Claim 6
Dependent Claim
48 words
An apparatus according to claim 3, wherein the floating arms of the conveying apparatus and the oil recovery unit are towed by the support vessel through hinged forks which allow the conveying apparatus, the recovery unit and the support vessel to float autonomously and independently of each other.
