Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
A SOLID FUEL CAPABLE OF DELIVERING A HIGH THRUST FOR PROPULSION IN TORPEDO, ROCKET AND RAM-JET ENGINE SYSTEMS COMPRISING ABOUT 50 TO 90 PARTS BY WEIGHT OF FINELY DIVIDED HIGH ENERGY PARTICLES OF A METAL-CONTAINING FUEL DISPERSED AND ENCASED WITHIN ABOUT 10 TO 50 PARTS BY WEIGHT OF A METALLIC MATRIX WHICH ALSO BURNS TO PROVIDE ENERGY FOR PROPULSION SAID FUEL PARTICLES BEING SELECTED FROM A MEMBER OF THE GROUP CONSISTING OF A METAL, A METAL HYDRIDE AND A METAL CARBIDE IN WHICH THE METAL IS SELECTED FROM A MEMBER OF THE GROUP CONSISTING OF ALUMINUM, MAGNESIUM, TITANIUM, LITHIUM, SILICON, BORON AND BERYLLIUM AND SAID METALLIC MATRIX IS SELECTED FROM A MEMBER OF THE GROUP CONSISTING OF LITHIUM, MAGNESIUM, ALUMINUM, BORON, A MAGNESIUM-ALUMINUM ALLOY, A MAGNESIUM-LITHIUM ALLOY, A MAGNESIUM-LITHIUM-ALUMINUM ALLOY AND AN ALUMINUM-LITHIUM ALLOY, THE METALLIC MATRIX FUSED AROUND THE SURROUNDING EACH FUEL PARTICLE TO DISPERSE THE FUEL PARTICLES SUBSTANTIALLY UNIFORMLY THROUGHOUT THE SOLID FUEL.

Claim 3
Independent Claim
162 words
A METHOD OF USING A FUEL COMPOSITION COMPRISING METAL-CONTAINING FUEL PARTICLES AND A METALLIC BINDER THEREFOR IN WHICH EACH OF THE FUEL PARTICLES IS ENCASED AND SURROUNDED BY THE METALLIC BINDER IN AN UNDERWATER VEHICLE POWERED BY INERTIAL PROPULSION, THE METHOD COMPRISING THE STEPS OF OXIDIZING SAID FUEL COMPOSITION TO OBTAIN HYDROGEN GAS IN WHICH THE FUEL PARTICLES ARE SELECTED FROM A MEMBER OF THE GROUP CONSISTING OF A METAL, A METAL HYDRIDE AND A METAL CARBIDE IN WHICH THE METAL IS SELECTED FROM A MEMBER OF THE GROUP CONSISTING OF ALUMINUM, MAGNESIUM, TITANIUM, LITHIUM, SILICON, BORON AND BERYLLIUM AND SAID METALLIC BINDER IS SELECTED FROM A MEMBER OF THE GROUP CONSISTING OF LITHIUM, MAGNESIUM, ALUMINUM, BORON, A MAGNESIUM-ALUMINUM ALLOY, A MAGNESIUM-LITHIUM ALLOY, A MAGNESIUM-LITHIUM-ALUMINUM ALLOY AND AN ALUMINUM-LITHIUM ALLOY, AND FILLING A CONTAINER WITH SAID HYDROGEN GAS TO PROVIDE A BUOYANT UPWARD FORCE FOR SAID VEHICLE AND REMOVING SAID GAS FROM SAID CONTAINER TO PROVIDE A DOWNWARD FORCE FOR SAID VEHICLE.
