Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
A device for recovering floating matter from water surface, comprising a floating frame body, a downwardly-directed bucket secured to the frame body and having an inlet opening disposed at a level below the water surface, a feeding means secured to the frame body in the proximity of said bucket, so as to feed the floating matter to the inlet opening of the downwardly-directed bucket, said bucket keeping water comparatively calm therein while causing the floating matter to move to top portion of the inside space of the bucket, and a suction means mounted on said frame body for removing the floating matter from the top portion of the bucket.
Claim 2
Independent Claim
109 words
A device for recovering floating matter from water surface, comprising a floating frame body, a downwardly-directed bucket secured to the frame body and having an inlet opening disposed at a level below the water surface, a feeding means secured to the frame body in the proximity of said bucket, so as to feed the floating matter to the inlet opening of the downwardly-directed bucket, said bucket keeping water comparatively calm therein while causing the floating matter to move to top portion of the inside space of the bucket, and a suction means mounted on said frame body for removing the floating matter from the top portion of the bucket.
Claim 3
Dependent Claim
22 words
A device for recovering floating matter according to claim 1 and further comprising a whirl-generating means which is disposed in said bucket.
Claim 4
Dependent Claim
46 words
A device for recovering floating matter according to claim 1 and further comprising a passage which is formed within said floating frame and has an opening communicating with outside water and another opening communicating with said bucket, wherein said feeding means is disposed within said passage.
Claim 5
Dependent Claim
49 words
A device for recovering floating matter according to claim 3 and further comprising a plurality of anti-reverse-flow boards which are disposed in said passage in parallel with each other below water level therein, each of said boards extends at right angles to direction of water flow toward said bucket.
Claim 6
Dependent Claim
68 words
A device according to claim 3, wherein said feeding means consists of an endless belt having an adsorptive member secured to outer surface thereof, a driving means causing rotation of said endless belt, and at least one squeezing roller engagiNg said endless belt, said endless belt moving along a closed loop extending from a point above water level to the proximity of said inlet opening of said bucket.
Claim 7
Dependent Claim
39 words
A device for recovering floating matter according to claim 4 and further comprising a wave-suppressing filter which is disposed at bottom portion of said passage and allows passage of water therethrough but inhibits passage of said floating matter therethrough.
Claim 8
Dependent Claim
74 words
A device according to claim 3, wherein said feeding means consists of an endless belt made of an elastomer, a driving means causing rotation of said endless belt so as to produce a flow of water and the floating matter along the outer surface thereof, and at least one rake-like member which faces said endless belt in such a manner that the flow caused by the endless belt is diverted toward the downwardly-directed bucket.
