Abstract
Abstract Floating device to remove refuse situated on and under a water surface, comprising a first and a second floating body and a hose-type duct with which the two floating bodies can be connected together via connecting openings, a water inlet feature and a mixing feature to mix the polluted water with a flocculation agent being installed on the first floating body and the hose-type duct forming a resting zone to calm the water and flocculate the refuse in the water and a feature to remove the flocculated sludge from the water being arranged on the second floating body.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
248 words
In combination with a body of water apparatus for purification of said body of water, said apparatus comprising a first floatable chamber constructed and arranged to be located at least partially beneath the surface of said body of water, inlet means located at a first end of said chamber and fluid pump means supported by said floatable chamber for introducing liquid with solid particles suspended therein from said body of water into said first chamber through said inlet, chemical flocculation means supported by said first chamber for introducing chemical flocculation agents into said first chamber, mixing means located in said first chamber for mixing chemical flocculation agents with the liquid in said chamber, elongate flexible duct means with a first end connected to an outlet in said chamber spaced apart from said inlet means, said flexible duct means being constructed and arranged to be of such a length for providing a residence zone for liquid introduced into said duct from said first chamber, a second inlet end of said duct connected to a second floatable chamber with a first end, said chamber being constructed and arranged to be located at least partially beneath the surface of said body of water, parallel plate separators located within said second chamber, outlet means located in a second end of said second chamber spaced apart from said inlet end whereby liquid introduced into said first chamber from the body of water by said pump means is returned to the body of water.

Claim 3
Dependent Claim
46 words
The floating device of claim 1 wherein a folding means is mounted on one of said first and second floatable chambers for folding and supporting said flexible duct, said folding means comprising an articulated arm which is adapted to engage the bottom of said flexible duct.
Claim 4
Dependent Claim
36 words
The floating device of claim 2 wherein said folding means further comprises a plurality of frames mounted on said one of said first and second floatable chambers each having means for inserting and fixing horizontal rods.
Claim 5
Dependent Claim
24 words
The floating device of claim 1 wherein said first and second floatable chambers each include means for sealing said liquid inlet and outlet means.
Claim 6
Dependent Claim
65 words
The floating device of claim 1 wherein winch means are mounted on said first and second floatable chambers, a cable is stretched between said winch means and adapted to be paid in and out as the distance between said first and second floatable chambers decreases and increases, respectively, and a float is attached to said cable and to said flexible duct to support the same.
Claim 7
Dependent Claim
43 words
The floating device of claim 1 wherein said parallel plate separators comprise plate divider means having a plurality of upwardly extending channels in the liquid flow direction and having suction pipe means positioned at the inlets of said channels for removing flocculated sludge.
Claim 8
Dependent Claim
22 words
The floating device of claim 1 wherein means for mixing chemical flocculation agents with liquid is mounted on said first floatable chamber.
Claim 9
Dependent Claim
15 words
The floating device of claim 1 wherein said flexible tubular duct is made of plastic.
Claim 10
Dependent Claim
32 words
The floating device of claim 1 wherein suction pipe means is mounted in said first chamber near said inlet means of said first floatable chamber to suck liquid into said first chamber.
Claim 11
Dependent Claim
16 words
The floating device of claim 1 and further comprising means for anchoring said first floatable chamber.
