Abstract
Abstract A floating containing vessel or dam for confining slicks of liquid pollutants. The vessel or dam comprises a flexible skirt connected at its upper portion to a float which provides buoyancy to the vessel, and at its lower portion to a ballast. The skirt forms an enclosure wherein the pollutants collect and the depth of the skirt varies from a maximum at the maximum interior position of the enclosure to a minimum at the towing ends of the vessel which define the entrance to the enclosure. The ballast is utilised as a towing means for towing the containing vessel or dam.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
Floating boom apparatus for collecting liquid floating on the surface of a body of water, said apparatus comprising elongate float means with an elongate strap member located along the length of said float means at the underside thereof, depending skirt means suspended from said float means, said skirt being constructed and arranged to be of substantially greater depth in the region between its ends than at each of its opposed ends, ballast means connected to the lower edge of the length of said skirt said ballast means comprising means extending beyond each end of said skirt for towing each end of said apparatus through said body of water, means connected to each end of said elongate strap member for adjustable connection of each end of said strap member to an adjacent portion of said towing member extending beyond each end of said float whereby said adjustable connection of each end of said strap to its adjacent towing member is effective to control the inclination of said downwardly depending skirt.
Claim 2
Dependent Claim
169 words
Floating boom apparatus for collecting liquid floating on the surface of a body of water, said apparatus comprising elongate float means with an elongate strap member located along the length of said float means at the underside thereof, depending skirt means suspended from said float means, said skirt being constructed and arranged to be of substantially greater depth in the region between its ends than at each of its opposed ends, ballast means connected to the lower edge of the length of said skirt said ballast means comprising means extending beyond each end of said skirt for towing each end of said apparatus through said body of water, means connected to each end of said elongate strap member for adjustable connection of each end of said strap member to an adjacent portion of said towing member extending beyond each end of said float whereby said adjustable connection of each end of said strap to its adjacent towing member is effective to control the inclination of said downwardly depending skirt.
Claim 3
Dependent Claim
42 words
A floating boom as claimed in claim 1, wherein the lower portion of the downwardly depending skirt is delimited by a straight line interconnecting the portion of maximum depth thereof with the portions of minimum depth at the ends of said skirt.
Claim 4
Dependent Claim
60 words
A floating boom as claimed in claim 1, wherein the lower portion of the downwardly depending skirt is delimited by a curvilinear line which interconnects the portion of maximum depth thereof with the portions of minimum depth at respective ends of the skirt; the portions of maximum and minimum depth lying rearwardly and forwardly in respectively of the containing vessel.
Claim 5
Dependent Claim
43 words
A floating boom as claimed in claim 1, wherein the ballast means is a chain, which is slidably movable in a guide, rigidly connected to the lower portion of the skirt, said guide having a length substantially equal to that of the skirt.
Claim 6
Dependent Claim
54 words
A floating boom as claimed in claim 1, wherein said float means comprise a plurality of inflatable float members and wherein at least one auxiliary bladder is arranged in each of the inflatable float members, the auxiliary bladder having a separate inflation orifice than that of the float member in which it is arranged.
Claim 7
Dependent Claim
21 words
A floating boom as claimed in claim 5, wherein the skirt comprises a plurality of elements assembled together by connecting means.
Claim 8
Dependent Claim
92 words
A floating boom as claimed in claim 6, wherein said connecting means comprises two profiled elements, each of which has two shoulders and are fixed to the ends of two adjacent elements of the skirt, said profiled elements each receiving two flexible curved plates, and attachment members which engage at least two holes provided in each of the profiled elements and corresponding holes in the flexible plates to connect the two profiled elements with the flexible plates together said attachment members being also attached to the strap and to the ballast means.
Claim 9
Dependent Claim
41 words
A floating boom, as claimed in claim 7, wherein the attachment members are screws, which are proviDed with nuts, said attachment members each having a ringed portion to which the strap and ballast means are respectively attached by means of snap-hooks.
