Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
An installation for influencing the sedimentation and movement of particles of materials in seas, lakes, and other bodies of water comprising anchoring means anchored to the submerged bottom and secured to said anchoring means are threads, tapes or filaments arranged in the form of a plurality of loops lying in generally vertical planes, the apexes and the legs of each loop being horizontally spaced apart linearly along the length of said anchoring means, wherein said loop arrangement comprises a series of interconnecting U-shaped loops with adjacent legs touching each other.
Claim 2
Dependent Claim
