Abstract
Abstract The lower portion of an oil salvage intensity separation chamber is supported in a body of fluid, such as sea-water, upon which a contaminent, such as oil, is floating and in such a manner that there is relative movement between the chamber's lower portion and the oil contaminated sea-water; so that the contaminent oil moves into the chamber and, because of its lighter density the oil in globs or globlets, floats up through a column of sea-water collected in the chamber to be separated into a layer floating on top of the sea-water column. The relative movement is accomplished by mounting the chamber between the pontoons of a catamaran type vessel. A positionable scoop directs the oil into an inlet opening provided in the lower portion of the chamber; while a deflector directs the oil up into the column of sea-water. Positionable sea gates are provided to either open the bottom of the chamber to the sea-water, or to close same off therefrom. A sea-water opening is also provided in the lower portion of the chamber, but removed from the inlet; with a set of valves and a pump in communication therewith to either facilitate accumulating the column of sea-water in the chamber, or the withdrawal of sea-water therefrom as the oil/sea-water separation process continues. An oil outlet and pump are provided in the upper portion of the chamber to draw off the separated oil; which may then be pumped through a suitable conduit to a collecting facility, such as a barge.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
283 words
A contaminent salvager; comprising: (a) chamber means of a size and configuration to receive and hold a predetermined quantity of fluid having a contaminent, said contaminent being of a lesser density and immiscible with said fluid, and wherein said chamber is sized to permit separation of said fluid and contaminent into immiscible layers. (b) carrying means for positioning said chamber means in a body of fluid which may have a contaminent floating upon its surface, wherein said carrying means is a water-going vessel of the catamaran type having a pair of pontoons disposed one to each side of said chamber means; (c) means to fill said chamber means to an operating level; (d) buoyancy regulation means comprising the elements of contaminated fluid inlet means leading directly into said chamber means proximate a lower portion thereof and being disposed between said pontoons; fluid outlet means leading directly from said chamber means proximate said lower portion thereof and spaced from said contaminated fluid inlet means; contaminent outlet means disposed proximate an upper portion of said chamber means; atmosphere communication means connecting said upper portion of said chamber means to the atmosphere above said position of said contaminent outlet mean; means for creating relative movement between said chamber means and the contaminated fluid so that contaminated fluid enters said inlet means; the contaminent floating up through said predetermined quantity of fluid to form a layer thereupon; and at least one fluid door means disposed below the level of said inlet and outlet means, and being openable and closable to the body of fluid to permit selective communication therewith, said elements functioning singly or in any combination thereof to maintain said salvager at a substantially constant buoyancy.
Claim 2
Dependent Claim
283 words
A contaminent salvager; comprising: (a) chamber means of a size and configuration to receive and hold a predetermined quantity of fluid having a contaminent, said contaminent being of a lesser density and immiscible with said fluid, and wherein said chamber is sized to permit separation of said fluid and contaminent into immiscible layers. (b) carrying means for positioning said chamber means in a body of fluid which may have a contaminent floating upon its surface, wherein said carrying means is a water-going vessel of the catamaran type having a pair of pontoons disposed one to each side of said chamber means; (c) means to fill said chamber means to an operating level; (d) buoyancy regulation means comprising the elements of contaminated fluid inlet means leading directly into said chamber means proximate a lower portion thereof and being disposed between said pontoons; fluid outlet means leading directly from said chamber means proximate said lower portion thereof and spaced from said contaminated fluid inlet means; contaminent outlet means disposed proximate an upper portion of said chamber means; atmosphere communication means connecting said upper portion of said chamber means to the atmosphere above said position of said contaminent outlet mean; means for creating relative movement between said chamber means and the contaminated fluid so that contaminated fluid enters said inlet means; the contaminent floating up through said predetermined quantity of fluid to form a layer thereupon; and at least one fluid door means disposed below the level of said inlet and outlet means, and being openable and closable to the body of fluid to permit selective communication therewith, said elements functioning singly or in any combination thereof to maintain said salvager at a substantially constant buoyancy.
Claim 3
Dependent Claim
17 words
The salvager of claim 1, wherein said chamber means is in the configuration of a cylindrical tank.
Claim 4
Dependent Claim
10 words
The salvager of claim 1, wherein the contaminent is oil.
Claim 5
Dependent Claim
52 words
The salvager of claim 1, wherein pump means are provided in communication with said fluid outlet means, to either pump fluid into said chamber means to facilitate disposition therein of said predetermined body of fluid; or to pump fluid from said chamber means while the salvager is separating contaminent from the fluid.
Claim 6
Dependent Claim
249 words
The salvager of claim 4, wherein said pump means includes: (a) first pipe means extending out from said fluid outlet means; (b) second pipe means extending from said first pipe means in a direction to be immersed into the body of fluid within which said chamber means is to be disposed, and dividing said first pipe means into a first pipe portion, extending from said fluid outlet from said chamber means to the place of inter-connection of said second pipe means and said first pipe means, and a second pipe portion extend from said place of inter-connection of said second pipe means to said first pipe means; (c) second pipe valve means disposed in said second pipe means; (d) first valve means disposed in said first pipe portion of said first pipe means; (e) said pump means communicating with said first pipe means in said second portion thereof; (f) by-pass pipe means leading from said first portion of said first pipe means, between said fluid outlet from said chamber means and said first valve means, to a place in said second portion of said first pipe means to the side of said pump means opposite to that where said second pipe means is disposed; (g) second valve means disposed in said second portion of said first pipe means at a location opposite to said place where said by-pass pipe communicates therewith from where said pump means is located; and (h) by-pass pipe valve means disposed in said by-pass pipe.
