Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
A METHOD FOR FORMING A HIGH DENSITY FIBROUS GLASS MASS INCLUDING FIBERS HAVIG WIDELY VARYING LENGTHS AND DIAMETERS, SAID METHOD COMPRISING CENTRIFUGING PRIMARY STREAMS OF MOLTEN GLAS OUTWARDLY ITO AN ANNULAR, DOWNWARDLY MOVING, EXPANDIG BLAST OF GASES, ENTRAINING THE STREAMS IN AND ATTENUATING THE STEAMS BY THE GASES OF THE BLAST, CREATING TURBULENCE ADJACENT AND IN THE OUTER MARGIN OF THE BLAST FOR FRACTURING AND INTERRUPTING THE ATTENUATION OF SOME OF THE FIBERS BEING ATTENUATED BY THE BLAST, APPLYING A SETTABLE ADHESIVE TO THE FIBERS, COLLECTING THE FIBERS IN THE FORM OF A LOOSE, LOW-DENSITY BLANKET, SUBJECTIG THE BLANKET TO A SEIRES OF COMPRESSIONS WITH INTERMEDIATE RELEASES OF PRESSURE AND RESULTING EXPANSION OF THE BLANKET FOR FRACTURING FIBERS AND ORIENTING SHORTER FIBERS GENERALLY NORMAL AND LONGER FIBERS GENERALLY PARALLEL TO THE MAJOR FACES OF THE BLANKET AND FINALLY COMPRESSING THE BLANKET TO THE DESIRED APPARENT DENSITY AND SETTING UP THE ADHESIVE WHILE RETAINING THE BLANKET AT SUCH DESIRED APPARENT DENSITY.
Claim 2
Independent Claim
160 words
A METHOD FOR FORMING A HIGH DENSITY FIBROUS GLASS MASS INCLUDING FIBERS HAVIG WIDELY VARYING LENGTHS AND DIAMETERS, SAID METHOD COMPRISING CENTRIFUGING PRIMARY STREAMS OF MOLTEN GLAS OUTWARDLY ITO AN ANNULAR, DOWNWARDLY MOVING, EXPANDIG BLAST OF GASES, ENTRAINING THE STREAMS IN AND ATTENUATING THE STEAMS BY THE GASES OF THE BLAST, CREATING TURBULENCE ADJACENT AND IN THE OUTER MARGIN OF THE BLAST FOR FRACTURING AND INTERRUPTING THE ATTENUATION OF SOME OF THE FIBERS BEING ATTENUATED BY THE BLAST, APPLYING A SETTABLE ADHESIVE TO THE FIBERS, COLLECTING THE FIBERS IN THE FORM OF A LOOSE, LOW-DENSITY BLANKET, SUBJECTIG THE BLANKET TO A SEIRES OF COMPRESSIONS WITH INTERMEDIATE RELEASES OF PRESSURE AND RESULTING EXPANSION OF THE BLANKET FOR FRACTURING FIBERS AND ORIENTING SHORTER FIBERS GENERALLY NORMAL AND LONGER FIBERS GENERALLY PARALLEL TO THE MAJOR FACES OF THE BLANKET AND FINALLY COMPRESSING THE BLANKET TO THE DESIRED APPARENT DENSITY AND SETTING UP THE ADHESIVE WHILE RETAINING THE BLANKET AT SUCH DESIRED APPARENT DENSITY.
Claim 3
Dependent Claim
208 words
APPARATUS FOR FORMNG A HIGH DENSITY FIBROUS GLAS MASS INCLUDING FIBERS HAVING WIDELY VARYING LENGTHS AND DIAMETERS, AND APPARATUS COMPRISING A CENTRIFUGE FOR PROJECTING PRIMARY STREAMS OF MOLTEN GLASS OUTWARDLY THEREFROM, MEANS FOR DIRECTING AN ANNULAR, DOWNWARDLY MOVING, EXPANDING BLAST OF GASES COAXIALLY WITH AND SPACED FROM SAID CENTRIFUGE, SAID BLAST HAVING SUFFICIENT KINETIC ENERGY FOR ENTRAINNG THE STREAMS AND ATTENUATING THE STEAMS BY THE GASES OF THE BLAST, MEANS FOR CREATING TURBULENCE ADJACENT AND IN THE OUTER MARGIN OF THE BLAST FOR FRACTURING AND INTERUPTING THE ATTENUATION OF SOME OF THE FIBERS BEING ATTENUATED BY THE BLAST, MEANS FOR APPLYING A SETTABLE ADHESIVE TO THE FIBERS, A CONVEYOR FOR COLLECTING THE FIBERS IN THE FORM OF A LOOSE LOW-DENSITY BLANKET, A PLURALITY OF SPACED COMPRESSION MECHANISMS FOR SUBJECTING THE BLANKET T A SERIES OF COMPRESSIONS WIT INTERMEDIATE RELEASES OF PRESSURE AND RESULTING EXPANSION OF THE BLANKET THEREBETWEEN FOR FRACTURING LARGER FIBERS AND ORIENTING SOME F THE SHORTER FIBERS GENERALLY NORMAL AND THE LONGER FIBERS GENERALLY PARALLEL TO THE MAJOR FACES OF THE BLANKET, MEANS FOR COMPRESSING THE BLANKET TO THE DESIRED APPARENT DENSITY AND A FURNACE WITH MEANS FOR FEEDING SAID BLANKET THERETHROUGH FOR SETTING UP THE ADHESIVE WHILE RETAINING THE BLANKET AT SUCH DESIRED APPARENT DENSITY.
