Claim 4

The oil concentrator as defined in claim 1 wherein said tank has a bottom and an upper edge; said first baffle means includes a first vertical baffle having a bottom portion fixed in spaced relation to said tank bottom and extends to said upper edge of said tank; and said second baffle means includes a second vertical baffle having an upper portion fixed in spaced relation from said upper edge and extending to said bottom of said tank.

Claim 5

The oil concentrator as defined in claim 3 wherein said means for agglomerating material includes an agglomeration baffle plate affixed to an upper portion of said second baffle and extends toward said first baffle a distance greater than one half the distance between said first and second vertical baffles and lies in a plane descending from said upper portion of said second baffle approximately forty-five degrees below a horizontal plane.

Claim 6

The oil concentrator as defined in claim 2 wherein said flow quietener baffle extends in a direction generally toward said second chamber at least to intersect a horizontal plane passing through said upper portion of said second baffle.

Claim 7

The oil concentrator as defined in claim 1 wherein said means for aerating the contents of said first chamber includes means for dispersing air into said mixture within said first chamber in the form of fine bubbles which rise slowly through said fluid and substantially permeate the contents of said chamber.

Claim 8

The oil concentrator as defined in claim 6 wherein said means for aerating further includes a metal strainer forming a multitude of aeration holes.

Claim 9

The oil concentrator as defined in claim 1 wherein said means for allowing fluid to ingress said first chamber includes a trumpet like flange affixed to the open end of a vertically positioned transport vessel.

Claim 10

The oil concentrator as defined in claim 1 further comprising means for draining the contents of said third chamber located within said third chamber.

Claim 11

The oil concentrator as defined in claim 1 further comprising means for adjusting the effective level of said light fluid outlet affixed to said light fluid outlet.

Claim 12

The oil concentrator as defined in claim 10 wherein said means for adjusting the effective level of said light fluid outlet includes an elbow threadably engaged within said tank to said light fluid outlet.

Claim 13

A waste oil concentrator for receiving and separating a mixture of oil and machine coolant comprising: a fluid tight tank having a bottom, a first end wall joined to said bottom and ascending vertically therefrom to an upper limit defining an upper edge, said upper edge encircling said tank a uniform distance from said bottom, a front side wall joined to said bottom and said first end wall and ascending vertically to said upper edge, a second end wall joined to said front side wall and said bottom and ascending vertically to said upper edge, a back side wall joined to said first and second end walls and to said bottom, and ascending vertically to said upper edge; a first chamber defined by an angled baffle plate affixed in fluid tight contact to said front and back side walls near said first end wall and having an upper portion positioned parallel to said first end wall, said upper portion of said baffle plate depending vertically from said upper edge for a predetermined distance, said angled baffle plate having a lower portion extending in a plane approximately forty five degrees below a horizontal plane and making a fluid tight contact with said upper portion and said first end wall; ingress means for introducing fluid containing oil and coolant into said first chamber said ingress means including a mounting plate extending between said front and back side walls near said first end wall; said angled baffle plate having means for egressing said fluid and means for quietening said egressing flow positioned adjacent said means for egressing; a first vertical baffle, extending between said front and back side walls and depending parallel to said second end wall, from said upper edge a distance less than the distance between said upper edge and said bottom near said second end wall; a second vertical baffle extending between said front and back side walls and ascending parallel to said second end wall from said bottom a distance less than the distance between said upper edge and said bottom, said second vertical baffle located between said first vertical baffle and said second end wall and having an upper edge; an agglomeration baffle affixed to said upper edge of said second vertical baffle and extending in a direction generally toward said first vertical baffle, said agglomeration baffle extending from said front wall to said back wall; means for allowing light fluid to egress said tank positioned in one of said side walls, between said first vertical baffle and said angled baffle plate, and; means for allowing heavy fluid to egress said tank positioned in said second end wall near said bottom.

Claim 14

A waste oil concentrator for receiving and separating a mixture of oil and machine coolant comprising: a fluid tight tank having a bottom, a first end wall joined to said bottom and ascending vertically therefrom to an upper limit defining an upper edge, said upper edge encircling said tank a uniform distance from said bottom, a front side wall joined to said bottom and said first end wall and ascending vertically to said upper edge, a second end wall joined to said front side wall and said bottom and ascending vertically to said upper edge, a back side wall joined to said first and second end walls and to said bottom, and ascending vertically to said upper edge; a first chamber defined by an angled baffle plate affixed in fluid tight contact to said front and back side walls near said first end wall and having an upper portion positioned parallel to said first end wall, said upper portion of said baffle plate depending vertically from said upper edge for a predetermined distance, said angled baffle plate having a lower portion extending in a plane approximately forty five degrees below a horizontal plane and making a fluid tight contact with said upper portion and said first end wall; ingress means for introducing fluid containing oil and coolant into said first chamber said ingress means including a mounting plate extending between said front and back side walls near said first end wall; said angled baffle plate having means for egressing said fluid and means for quietening said egressing flow positioned adjacent said means for egressing; a first vertical baffle, extending between said front and back side walls and depending parallel to said second end wall, from said upper edge a distance less than the distance between said upper edge and said bottom near said second end wall; a second vertical baffle extending between said front and back side walls and ascending parallel to said second end wall from said bottom a distance less than the distance between said upper edge and said bottom, said second vertical baffle located between said first vertical baffle and said second end wall and having an upper edge; an agglomeration baffle affixed to said upper edge of said second vertical baffle and extending in a direction generally toward said first vertical baffle, said agglomeration baffle extending from said front wall to said back wall; means for allowing light fluid to egress said tank positioned in one of said side walls, between said first vertical baffle and said angled baffle plate, and; means for allowing heavy fluid to egress said tank positioned in said second end wall near said bottom.
