Process of making a bonded exothermic composition

Claim 1

THE PROCESS OF MAKING AN EXOTHERINE REACTION BLOCK FOR USE IN ADDING AN ALLOYING METALLIC CONSTITUENT TO BASE METALS, COMPRISING: MIXING IN PULVERULENT FORM UNTIL INTIMATELY AND UNIFORMLY BLENDED AN ALLOYING METALLIC CONSTITUENT, A REDUCING MATERIAL, AN OXIDIZING AGENT, AND A THERMOLPLASTIC RESINOUS MATERIAL HAVING A SOFTENING POINT WELL BELOW THE IGNITION POINT OF A MIXTURE OF SAID REDUCING MATERIAL AND SAID OXIDIZING AGENT; CONFINING THE RESULTING MIXTURE IN A METALLIC CONTAINER; HEATING THE MIXTURE TO A TEMPERATURE ABOVE SAID SOFTENING POINT BUT WELL BELOW SAID IGNITION POINT TO CONVERT SAID RESINOUS MATERIAL TO A LIQUID SUFFICIENTLY VISCOUS THAT THE REMAINING PULVERULENT INGREDIENTS WILL NOT STRATIFY THEREIN, SAID VISCOUS LIQUID SOLIDIFYING ON COOLING TO FIRMLY BOND THE MIXTURE OF ALLOYING METALLIC CONSTITUENT, REDUCING MATERIAL AND OXIDIZING AGENT, AND MAINTAIN THE UNIFORMITY THEREOF.
