Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
59 words
AS A NEW COMPOSITION OF MATTER, A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM AND MAGNESIUM IN A CONTINUOUS PHASE, PARTICLES OF URANOSIC OXIDE UNIFORMLY DISPERSED AND EMBEDDED IN SAID METAL, SAID PARTICLES HAVING A SURFACE LAYER OF URANIUM DIOXIDE AND SAID METAL HAVING A LAYER OF THE OXIDE OF SAID METAL AT THE INTERFACE WITH SAID PARTICLES.
Claim 2
Dependent Claim
59 words
AS A NEW COMPOSITION OF MATTER, A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM AND MAGNESIUM IN A CONTINUOUS PHASE, PARTICLES OF URANOSIC OXIDE UNIFORMLY DISPERSED AND EMBEDDED IN SAID METAL, SAID PARTICLES HAVING A SURFACE LAYER OF URANIUM DIOXIDE AND SAID METAL HAVING A LAYER OF THE OXIDE OF SAID METAL AT THE INTERFACE WITH SAID PARTICLES.
Claim 3
Independent Claim
84 words
A METHOD OF MAKING FUEL ELEMENTS COMPRISING MIXING POWDER PARTICLES OF A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM AND MAGNESIUM WITH POWDER PARTICLES OF URANOSIC OXIDE; SHAPING THE MIXTURE AT ELEVATED TEMPERATURE UNDER PRESSURE WHEREBY SAID METAL REDUCES URANOSLIC OXIDE ON THE SURFACE LAYER OF SAID PARTICLES TO URANIUM DIOXIDE, OXIDE OF SAID METAL IS FORMED ON THE SURFACE LAYER OF SAID METAL PARTICLES AND SAID METAL OXIDE-COVERED METAL PARTICLES AND SAID URANIUM DIOXIDECOVERED PARTICLES OF URANOSIC OXIDE ARE INTEGRALY BONDED TOGETHER.
