Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
247 words
A system for generating an emulsified fuel, comprising: (a) first reservoir means for containing a quantity of fuel component; (b) second reservoir means for containing a quantity of a non-combustible emulsion component; (c) chamber means defining an output and a mixing chamber having an input for receiving said fuel component and said non-combustible emulsion component and outputing both of said components at its output; (d) first means for providing said non-combustible component to said chamber means; (e) second means for providing said fuel component to said chamber means; (f) emulsifier means for receiving at its input both of said components from the output of said chamber means, and providing an emulsion at its output; (g) third means for providing both of said components from the output of said chamber means to the emulsifier means; (h) fourth means for providing at least a portion of the output of said emulsifier means to a device which consumes the emulsion of said fuel component an said non-combustible component; (i) recirculation means for receiving that portion of said emulsion not provided to said device and returning it to said chamber means, allowing said portion not provided to said device to be returned to the emulsifier means; (j) measurement means for measuring the ratio of the amount of said fuel component to the amount of said non-combustible component in said recirculation means; and (k) control means responsive to said measurement means to vary the flow of said components to control said ratio.
Claim 2
Independent Claim
247 words
A system for generating an emulsified fuel, comprising: (a) first reservoir means for containing a quantity of fuel component; (b) second reservoir means for containing a quantity of a non-combustible emulsion component; (c) chamber means defining an output and a mixing chamber having an input for receiving said fuel component and said non-combustible emulsion component and outputing both of said components at its output; (d) first means for providing said non-combustible component to said chamber means; (e) second means for providing said fuel component to said chamber means; (f) emulsifier means for receiving at its input both of said components from the output of said chamber means, and providing an emulsion at its output; (g) third means for providing both of said components from the output of said chamber means to the emulsifier means; (h) fourth means for providing at least a portion of the output of said emulsifier means to a device which consumes the emulsion of said fuel component an said non-combustible component; (i) recirculation means for receiving that portion of said emulsion not provided to said device and returning it to said chamber means, allowing said portion not provided to said device to be returned to the emulsifier means; (j) measurement means for measuring the ratio of the amount of said fuel component to the amount of said non-combustible component in said recirculation means; and (k) control means responsive to said measurement means to vary the flow of said components to control said ratio.
Claim 3
Dependent Claim
88 words
A system as in claim 1, wherein said measurement means comprises a conduit portion for receiving and transmitting said portion of said emulsion not provided to said device, said conduit portion including a pair of conductive members insulated from each other and positioned in facing relationship to each other with the flow of said portion of said emulsion not provided to said devices between them and capacitance measurement means for measuring the capacitance between said pair of conductive members and providing a control signal to said control means.
Claim 4
Dependent Claim
30 words
A system as in claim 2, wherein said device is an internal combustion engine and wherein said control means varies said ratio in response to the output of said engine.
Claim 5
Dependent Claim
33 words
A system as in claim 2, wherein said device is an internal combustion engine and said control means varies said ratio in response to the amount of emulsion being consumed by the engine.
Claim 6
Dependent Claim
32 words
A system as in claim 2, wherein said fuel component is hydrocarbon and wherein said second reservoir means is a condensation device which removes water from the combustion products of said device.
Claim 7
Dependent Claim
19 words
A system as in claim 2 wherein said conductive members are separated by a distance greater than one cm.
Claim 8
Independent Claim
15 words
A system as in claims 1 or 2 wherein said emulsifier means is a pump.
Claim 9
Independent Claim
212 words
A system for generating an emulsified fuel, comprising: (a) first reservoir means for containing a quantity of a fuel component; (b) second reservoir means for containing a quantity of a non-combustible emulsion component; (c) chamber means defining an output and a mixing chamber having an input for receiving said fuel component and said non-combustible emulsion component and outputing both of said components at its output; (d) first means for providing said non-combustible component to said chamber means; (e) second means for providing said fuel component to said chamber means; (f) emulsifier means for receiving at its input both of said components from the output of said chamber means, and providing an emulsion at its output; (g) third means for providing both of said components from the output of said chamber means to the emulsifier means; (h) fourth means for providing at least a portion of the output of said emulsifier means to a device which consumes the emulsion of said fuel component and said non-combustible component; (i) measurement means for measuring the ratio of the amount of said fuel component to the amount of said non-combustible component exiting said fourth means; and (j) flow control means responsive to said measurement means to vary the flow of said components to control said flow.
