Abstract
Abstract A human conveyance has a fuel-burning engine and a toilet which discharges to a waste storage tank. Effluent from the storage tank is fed to an evaporating device where the effluent is subjected to a first temperature which evaporates the effluent to form effluent vapor. The effluent vapor is directed to a second heating device which subjects the waste temperature to a second temperature substantially greater than the evaporating temperature. The heating device which subjects the effluent vapor to the second temperature may be defined by the intake or exhaust ports of the fuel-burning engine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
34 words
The device of claim 1 wherein said engine has an intake manifold and an exhaust manifold and said conduit means is connected to deliver vapor from said vaporizing means to one of said manifolds.
Claim 2
Dependent Claim
27 words
The device of claim 1 wherein said conduit means is connected to deliver vapor from said vaporizing means to said exhaust system upstream of said vaporizing means.
Claim 3
Dependent Claim
25 words
The device of claim 1 and further including air feed means for feeding air through said conduit means along with vapor from said vaporizing means.
Claim 4
Dependent Claim
34 words
The device of claim 4 wherein said air feed means includes an air inlet in said vaporizing means whereby air flows into said air inlet and through said vaporizing means to said conduit means.
Claim 5
Dependent Claim
102 words
A waste-disposal system including a heat-producing fuel-burning engine having an exhaust system for discharging hot gases from said engine, waste tank means for receiver liquid and organic waste material, vaporizing means for vaporizing said waste material, flow means for feeding waste material from said waste tank means to said vaporizing means, heat transfer means for transferring heat from hot gases flowing through said exhaust system to said vaporizing means to vaporize waste material in said vaporizing means, said vaporizing means having an outlet for vapor produced therein, and air feed means for feeding air through said vaporizing means and out said outlet.
Claim 6
Independent Claim
127 words
A method for disposing of liquid and organic waste material with a system including a heat-producing fuel-burning engine having an exhaust system, a waste tank for receiving waste material and vaporiZing means for vaporizing said waste material, comprising the steps of; feeding waste material from said waste tank to said vaporizing means, transferring heat to said vaporizing means from hot gases flowing through said exhaust system to vaporize waste material in said vaporizing means and reduce the temperature of hot gases flowing through said exhaust system downstream of said vaporizing means, and directing vapor from said vaporizing means to a heat source produced by said engine at a temperature substantially greater than the temperature of hot gases flowing through said exhaust system downstream of said vaporizing means.
Claim 7
Dependent Claim
37 words
The method of claim 7 wherein said engine includes an exhaust manifold and an intake manifold and said step of feeding vapor from said vaporizing means is carried out by feeding vapor to one of said manifolds.
Claim 8
Dependent Claim
24 words
The method of claim 7 and further including the step of feeding air to said heat source along with vapor from said vaporizing means.
Claim 9
Dependent Claim
26 words
The method of claim 9 wherein said step of feeding air to said heat source is carried out by first feeding air through said vaporizing means.
Claim 10
Independent Claim
81 words
A method for disposing of liquid and organic waste material with a system including a heat-producing fuel-burning engine having an exhaust system, a waste tank for receiving waste material and vaporizing means for vaporizing said waste material, comprising the steps of; feeding waste material from said waste tank to said vaporizing means, transferring heat to said vaporizing means from hot gases flowing through said exhaust system to vaporize waste material in said vaporizing means, and feeding air to said vaporizing means.
Claim 11
Dependent Claim
45 words
The method of claim 11 wherein said vaporizing means has an outlet connected with said exhaust system and said step of feeding air to said vaporizing means is carried out by feeding air through said vaporizing means and out said outlet to said exhaust system.
