Abstract
Abstract A device for receiving water suface floating impurities in the collecting receptacle of an oil and garbage skimmer craft comprises a gate installed at the inlet to the collecting receptacle. The upper horizontal edge of the gate forms a weir above which the upper layer of water together with floating impurities is overflowing. The gate is rigidly connected to a float, whereas both the gate and the float are fixed with a possibility for free rocking around a horizontal axis, thus providing for a constant depth of immersion of the upper horizontal edge of the gate in relation to the water level in a basin being cleaned. The gate has an outside surface facing a water basis being cleaned and is given the shape of a portion of a cylinder whose axis coincides with a horizontal axis around which the gate and the float are rocking.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
198 words
A device for receiving water surface floating impurities in the collecting receptacle of an oil and garbage skimmer craft, comprising: a gate installed at an inlet of the collecting receptacle and having an upper horizontal edge forming a weir, the upper layer of water together with flowing impurities being adapted to overflow the weir, said gate being located adjacent to the walls of said collecting receptacle; means supporting said gate for free rocking movement about a horizontal axis, said gate having an outer surface facing a water basin which is being cleaned, said surface comprising a portion of a cylinder having a longitudinal axis coextensive with the rocking axis Of said gate; at least one float fastened for rocking movement about said horizontal gate rocking axis; a link forming a pivotal connection between said gate and said float, said link providing a rigid connection therebetween; a hydraulic cylinder having a hydraulic lock positioned in said link, said cylinder providing for variation and setting in the length of said link whereby the immersion depth of said upper horizontal edge of said gate can be controlled with respect to the water level in the water basin which is being cleaned.

A device for receiving water surface floating impurities in the collecting receptacle of an oil and garbage skimmer craft, comprising: a gate installed at an inlet of the collecting receptacle and having an upper horizontal edge forming a weir, the upper layer of water together with flowing impurities being adapted to overflow the weir, said gate being located adjacent to the walls of said collecting receptacle; means supporting said gate for free rocking movement about a horizontal axis, said gate having an outer surface facing a water basin which is being cleaned, said surface comprising a portion of a cylinder having a longitudinal axis coextensive with the rocking axis Of said gate; at least one float fastened for rocking movement about said horizontal gate rocking axis; a link forming a pivotal connection between said gate and said float, said link providing a rigid connection therebetween; a hydraulic cylinder having a hydraulic lock positioned in said link, said cylinder providing for variation and setting in the length of said link whereby the immersion depth of said upper horizontal edge of said gate can be controlled with respect to the water level in the water basin which is being cleaned.
Claim 3
Dependent Claim
16 words
A device as claimed in claim 1, said gate having a streamlined body configuration in cross-section.
Claim 4
Dependent Claim
38 words
A device as claimed in claim 1, comprising a seal between said gate and the walls of said collecting receptacle adjacent thereto, said seal preventing water leakage into said collecting receptacle while permitting rocking movement of said gate.
Claim 5
Dependent Claim
30 words
A device as claimed in claim 1, said gate being located in an open-bottomed enclosure, said enclosure protecting said float against hydrodynamic effects caused by surrounding water of said basin.
