Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
96 words
A METHOD OF FORMING FIBERS FROM MOLTEN MINERAL MATERIAL WHICH INCLUDES ESTABLISHING A HIGH VELOCITY BLAST; OF FLOWING A STREAM OF MOLTEN MINERAL MATERIAL INTO THE BLAST; OF DIRECTING THE PATH OF MOVEMENT OF INDUCED AIR AT ONE SIDE OF THE BLAST TOWARD THE SOURCE OF THE BLAST WHEREBY THE INDUCED AIR AIDS IN MOVING THE MOLTEN STREAM OF MATERIAL INTO THE HIGH VELOCITY ZONE OF THE BLAST TOWARD THE SOURCE OF THE BLAST FOR CONTINUOUSLY ATTENUATING THE STREAM OF MATERIAL INTO FINE FIBERS, AND OF COLLECTING THE FIBERS IN A ZONE REMOTE FROM THE BLAST.

Claim 3
Dependent Claim
106 words
APPARATUS FOR FORMING FIBERS FROM A BODY OF FIBERFORMING MATERIAL, IN COMBINATION, A MEMBER HAVING AN ORIFICE FORMED THEREIN; MEANS FOR ESTABLISHING A HIGH VELOCITY BLAST ADAPTED FOR DISCHARGE THROUGH SID ORIFICE; SAID MEMBER HAVING A WALL PORTION ANGULARLY DIRECTED TOWARD THE ORIFICE; MEANS FOR FORMING A MOVING BODY OF FIBER-FORMING MATERIAL; MEANS FOR FORMING A MOVING BODY THE MEMBER AND DISPOSED AT ONE SIDE OF THE BLAST FOR DIRECTING THE PATH OF MOVEMENT OF AIR CURRENTS INDUCED BY THE VELOCITY OF THE BLAST TO ESTABLISH A FORCE BIASING THE MOVING BODY OF FIBER-FORMING MATERIAL TOWARD THE ANGULARLY DIRECTED SURFACE INTO THE BLAST ADJACENT THE ORIFICE.
