Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
67 words
An artificial seaweed array comprising of loops of strands arranged in the form of a plurality of loops lying in generally vertical planes, the apexes of the loops being free floating within a body of water and the legs of each loop being horizontally spaced apart but forming a series of interconnecting U-shaped loops with adjacent legs touching each other and attached to a reticular base structure.
Claim 2
Dependent Claim
67 words
An artificial seaweed array comprising of loops of strands arranged in the form of a plurality of loops lying in generally vertical planes, the apexes of the loops being free floating within a body of water and the legs of each loop being horizontally spaced apart but forming a series of interconnecting U-shaped loops with adjacent legs touching each other and attached to a reticular base structure.
Claim 3
Dependent Claim
12 words
An array according to claim 1 wherein the loops are self buoyant.
Claim 4
Dependent Claim
26 words
An array according to claim 2 wherein the material comprising the loops is selected from the group consisting of polyethylene, polypropylene or a cellular thermoplastic polymer.
Claim 5
Dependent Claim
22 words
An array according to claim 1 wherein the loops are denser than the water into which the array is to be laid.
Claim 6
Dependent Claim
25 words
An array according to claim 4 wherein the loops comprise strands of a material selected from the group consisting of a polyester or a polyamide.
Claim 7
Dependent Claim
30 words
An array according to claim 1 wherein at least part of the reticular base structure is a cable comprising a bundle of substantially parallel filaments encased in a thermoplastic sheath.
Claim 8
Dependent Claim
15 words
An array according to claim 1 wherein cross-over points of the base structure are joined.
Claim 9
Independent Claim
107 words
A method for influencing the sedimentation and movement of solid particles of material in seas, lakes and other bodies of water wherein an array of artificial seaweed comprising a plurality of loops of strands arranged in the form of a plurality of loops lying in generally vertical planes, the apexes of the loops being free floating within a body of water and the legs of each loop being horizontally spaced apart but forming a series of interconnecting U-shaped loops with adjacent legs touching each other and attached to a reticular base structure is placed at the bottom of a body of water and secured by anchoring means.
Claim 10
Independent Claim
107 words
A method for influencing the sedimentation and movement of solid particles of material in seas, lakes and other bodies of water wherein an array of artificial seaweed comprising a plurality of loops of strands arranged in the form of a plurality of loops lying in generally vertical planes, the apexes of the loops being free floating within a body of water and the legs of each loop being horizontally spaced apart but forming a series of interconnecting U-shaped loops with adjacent legs touching each other and attached to a reticular base structure is placed at the bottom of a body of water and secured by anchoring means.
Claim 11
Dependent Claim
61 words
A method according to claim 8 wherein one end of the array wound on a beam or drum mounted on a floating behind a boat or barge is secured to the bottom of a body of water and the array is placed thereon by moving the boat or barge in the required direction and allowing the beam or drum to unwind.
Claim 12
Dependent Claim
107 words
An installation for influencing the sedimentation and movement of particles of material in seas, lakes and other bodies of water comprising strand material submerged within the body of water and arranged in the form of a plurality of loops lying in generally vertical planes, the apexes of the loops being free floating within the body of water and the legs of each loop being horizontally spaced apart but forming a series of interconnecting U-shaped loops with adjacent legs touching each other and said loop being directly attached to a reticular structure constructed of ropes or cables; and means for anchoring the reticular structure to the submerged bottom.
Claim 13
Dependent Claim
107 words
An installation for influencing the sedimentation and movement of particles of material in seas, lakes and other bodies of water comprising strand material submerged within the body of water and arranged in the form of a plurality of loops lying in generally vertical planes, the apexes of the loops being free floating within the body of water and the legs of each loop being horizontally spaced apart but forming a series of interconnecting U-shaped loops with adjacent legs touching each other and said loop being directly attached to a reticular structure constructed of ropes or cables; and means for anchoring the reticular structure to the submerged bottom.
Claim 14
Dependent Claim
27 words
An installation as in claim 10 wherein each loop is formed of a bundle of strand material the strands of which lie generally parallel to each other.
