Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
25 words
The invention of claim 1 including fastening means on said free ends whereby said ends may be fastened together to form a circumscribing impounding device.
Claim 2
Dependent Claim
22 words
The invention of claim 1 wherein said strap is flexible to permit said web to undulate horizontally normal to its longitudinal axis.
Claim 3
Dependent Claim
35 words
The invention of claim 1 wherein said strap is flexible to thereby permit said web undulation in the plane of said barrier as limited by the ability of said upper and lower portions to fan.
Claim 4
Independent Claim
149 words
A device for impounding oil or other substances floating on or near the surface of a body of water comprising an elongated weblike barrier of semirigid material having an elongated top edge and an elongated bottom edge, said barrier comprising hollow segments spaced longitudinally of said barrier and extending transversely thereof, said segments being expansible and collapsible to increase and decrease the length of said barrier, means connecting said segments, and a substantially constant fixed-length strap joined to and extending longitudinally of said barrier along a plurality of points intermediate said top and bottom edges whereby when said hollow segments expand and collapse, the portions of said barrier between said edges and said strap are permitted to fan about horizontal axes extending through said points and normal to said barrier, said barrier being of sufficient buoyancy to maintain said top edge above the surface of said body of water.
Claim 5
Dependent Claim
19 words
The invention of claim 5 wherein said bArrier comprises opposed semirigid corrugated sheets joined to define said hollow segments.
Claim 6
Dependent Claim
25 words
The invention of claim 5 wherein said barrier has two free ends and including fastening means on said free ends for joining said free ends.
Claim 7
Dependent Claim
22 words
The invention of claim 5 wherein said strap is flexible to permit said barrier to undulate horizontally normal to its longitudinal axis.
Claim 8
Dependent Claim
36 words
The invention of claim 5 wherein said strap is flexible to thereby permit said barrier to undulate in the plane of said barrier as limited by the ability of said upper and lower ends to fan.
Claim 9
Dependent Claim
23 words
The invention of claim 6 wherein said corrugated sheets are joined at abutting lands, and said hollow segments are hexagonal in cross section.
Claim 10
Dependent Claim
22 words
The invention of claim 5 including ballast means and buoyant means affixed to the lower and upper portions of said barrier respectively.
Claim 11
Dependent Claim
11 words
The invention of claim 5 wherein said barrier is of aluminum.
Claim 12
Dependent Claim
11 words
The invention of claim 5 wherein said barrier is of plastic.
Claim 13
Dependent Claim
32 words
The invention of claim 7 wherein said fastening means includes a U-shaped channel extending along the edge of each free end and a locking means insertable in said channels joining said ends.
