Abstract
Abstract Mobile apparatus and a method for reprocessing waste crank case oil product and mixing this product with fuel oil in preselected proportions to render said product useful as a fuel. The apparatus is designed to be mounted on a vehicle so that processing is done in situ with the waste oil product being withdrawn, reprocessed, mixed, and discharged into the fuel oil tank taking place at the same time.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
A compact mobile system for reprocessing on a continuous basis a waste oil product for use as a fuel comprising means for withdrawing said waste oil product until exhausted or otherwise terminated from a first reservoir means in which said product is collected, means for filtering on stream said product to remove foreign particulate matter, means for simultaneously withdrawing fuel oil from a second reservoir means in which said oil is stored for use, means for mixing on stream the filtered product and said oil, means for filtering on stream the mixture to remove water and additional foreign particulate matter, means for simultaneously supplying said mixture to said second reservoir means while fuel oil is being withdrawn from said second reservoir, and manifold means which includes said means for withdrawing fuel oil from, and said means for supplying said mixture to, said second reservoir means as a unitary structure.
Claim 2
Dependent Claim
149 words
A compact mobile system for reprocessing on a continuous basis a waste oil product for use as a fuel comprising means for withdrawing said waste oil product until exhausted or otherwise terminated from a first reservoir means in which said product is collected, means for filtering on stream said product to remove foreign particulate matter, means for simultaneously withdrawing fuel oil from a second reservoir means in which said oil is stored for use, means for mixing on stream the filtered product and said oil, means for filtering on stream the mixture to remove water and additional foreign particulate matter, means for simultaneously supplying said mixture to said second reservoir means while fuel oil is being withdrawn from said second reservoir, and manifold means which includes said means for withdrawing fuel oil from, and said means for supplying said mixture to, said second reservoir means as a unitary structure.
Claim 3
Dependent Claim
73 words
The mobile system of claim 1 in which said unitary structure consists of first and second pipes, said first pipe extending the full length of said manifold means and having an inlet opening at the bottom thereof for said fuel oil, said second pipe terminating at its bottom with an opening at a point above the bottom of said first pipe inlet opening for the discharge of mixture into said second reservoir means.
Claim 4
Dependent Claim
32 words
The mobile system of claim 2 in which said second pipe is slidably adjustable with respect to said first pipe for adjusting the height at which said second pipe discharges said mixture.
Claim 5
Dependent Claim
16 words
The mobile system of claim 3 in which said system is mounted on a powered vehicle.
Claim 6
Dependent Claim
23 words
The mobile system of claim 4 having means for measuring the volumetric flow of said product being withdrawn from said first reservoir means.
Claim 7
Independent Claim
108 words
A method for the in situ reprocessing of waste oil product for use as a fuel comprising continuously and simultaneously carrying out the steps of withdrawing said waste oil product from a first reservoir means in which said product has been collected, filtering said product to remove foreign particulate matter, withdrawing fuel oil from a second reservoir means in which said oil is stored for use, mixing the filtered product and said oil, adjusting the volumetric ratio of said product to said oil to obtain a preselected mixture, filtering the mixture to remove water and other foreign particulate matter, and supplying said mixture to said second reservoir means.
Claim 8
Independent Claim
108 words
A method for the in situ reprocessing of waste oil product for use as a fuel comprising continuously and simultaneously carrying out the steps of withdrawing said waste oil product from a first reservoir means in which said product has been collected, filtering said product to remove foreign particulate matter, withdrawing fuel oil from a second reservoir means in which said oil is stored for use, mixing the filtered product and said oil, adjusting the volumetric ratio of said product to said oil to obtain a preselected mixture, filtering the mixture to remove water and other foreign particulate matter, and supplying said mixture to said second reservoir means.
Claim 9
Dependent Claim
36 words
The method of claim 6 in which the fuel oil is withdrawn and the mixture is discharged into said second reservoir means through a unitary structure to render efficient and quick the application of said method.
Claim 10
Dependent Claim
31 words
The method of claim 7 in which all of the apparatus required for carrying out the steps of the method is carried on a vehicle for facilitating the in situ reprocessing.
Claim 11
Dependent Claim
17 words
The method of claim 8 in which the volumetric flow of said waste oil product is measured.
