Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
IN A METHOD OF OPERATING A THRUST PROPELLANT MOTOR, WHEREIN FUEL COMPRISING METAL AS A COMPONENT IS BURNED IN A COMBUSTION CHAMBER AND THE PRODUCTS OF COMBUSTION ARE ALLOWED TO ESCAPE THROUGH A JET, THEREBY PRODUCING A DRIVING FORCE, THE IMPROVEMENT WHICH COMPRISES UTILIZING, A METAL SELECTED FROM THE GROUP CONSISTING OF BERYLLIUM, ALUMINUM, ZIRCONIUM, MAGNESIUM, TITANIUM, CHROMIUM, MIXTURES AND ALLOYS OF THE FOREGOING AND MIXTURES AND ALLOYS CONTAINING AT LEAST ONE OF THE FOREGOING, SAID METAL HAVING A SURFACE COATING WHICH IS AN AMALGAM OF SAID METAL, CHARACTERIZED BY AN IGNITION TEMPERATURE WHICH IS LOWER THAN THE IGNITION TEMPERATURE OF SAID METAL ITSELF.
Claim 2
Dependent Claim
104 words
IN A METHOD OF OPERATING A THRUST PROPELLANT MOTOR, WHEREIN FUEL COMPRISING METAL AS A COMPONENT IS BURNED IN A COMBUSTION CHAMBER AND THE PRODUCTS OF COMBUSTION ARE ALLOWED TO ESCAPE THROUGH A JET, THEREBY PRODUCING A DRIVING FORCE, THE IMPROVEMENT WHICH COMPRISES UTILIZING, A METAL SELECTED FROM THE GROUP CONSISTING OF BERYLLIUM, ALUMINUM, ZIRCONIUM, MAGNESIUM, TITANIUM, CHROMIUM, MIXTURES AND ALLOYS OF THE FOREGOING AND MIXTURES AND ALLOYS CONTAINING AT LEAST ONE OF THE FOREGOING, SAID METAL HAVING A SURFACE COATING WHICH IS AN AMALGAM OF SAID METAL, CHARACTERIZED BY AN IGNITION TEMPERATURE WHICH IS LOWER THAN THE IGNITION TEMPERATURE OF SAID METAL ITSELF.
Claim 3
Dependent Claim
98 words
IN A METHOD FOR PREPARING A FUEL COMPOSITION CONTAINING A HIGH ENERGY METAL SELECTED FROM THE GROUP CONSISTING OF BERYLLIUM, ALUMINUM, ZIRCONIUM, MAGNESIUM, TITANIUM, CHROMIUM, MIXTURES AND ALLOYS OF THE FOREGOING AND MIXTURES AND ALLOYS CONTAINING AT LEAST ONE OF THE FOREGOING THE IMPROVEMENT WHICH COMPRISES CONTACTING THE METAL WITH A MEMBER SELECTED FROM THE GROUP CONSISTING OF MERCURY AND SALTS OF MERCURY UNDER CONDITIONS SUCH THAT AN AMALGAM OF SAID METAL, CHARACTERIZED BY AN IGNITION TEMPERATURE WHICH IS LOWER THAN THE IGNITION TEMPERATURE OF SAID METAL ITSELF, FORMS AS A COATING ON THE SURFACE OF SAID METAL.
