Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
78 words
THE METHOD OF MANUFACTURE OF GLASS FIBERS OF A FINELY CONTROLLED DIAMETER, WHICH COMPRISES SPINNING BY GRAVITY A PLUTALITY OF THIN FIBER STREAM IN FILAMENTARY FORM FROM A MASS OF MOLTEN GLASS AT A PREDETERMINED TEMPERATURE INTO AN ENCLOSING HOOD WHEREFROM THE FIBRS ARE DRAWN, BLOWING A GASEOUS FLUID INTO SAID HOOD FOR INTERACTION WITH SAID FIBER STREAM, AND VARYING THE CHARACTERISTICS OF SAID GASEOUS FLUID TO CONTROL THE DIAMETERS OF THE GLASS FIBERS ISSUING FROM SAID HOOD.
Claim 2
Independent Claim
78 words
THE METHOD OF MANUFACTURE OF GLASS FIBERS OF A FINELY CONTROLLED DIAMETER, WHICH COMPRISES SPINNING BY GRAVITY A PLUTALITY OF THIN FIBER STREAM IN FILAMENTARY FORM FROM A MASS OF MOLTEN GLASS AT A PREDETERMINED TEMPERATURE INTO AN ENCLOSING HOOD WHEREFROM THE FIBRS ARE DRAWN, BLOWING A GASEOUS FLUID INTO SAID HOOD FOR INTERACTION WITH SAID FIBER STREAM, AND VARYING THE CHARACTERISTICS OF SAID GASEOUS FLUID TO CONTROL THE DIAMETERS OF THE GLASS FIBERS ISSUING FROM SAID HOOD.
Claim 3
Dependent Claim
141 words
IN AN APPARATUS FOR THE MANUFACTURE OF MINERAL THERMOPLASTIC MATERIAL, IN PARTICULAR GLASS FIBERS, THE COMBINATION OF A BUSHING HAVING IN ITS LOWER PART OF PLURALITY OF NIPPLES THROUGH WHICH THE MOLTEN GLASS ISSUES IN CONES, MEANS FOR DRAWING THE FIBERS AS FORMED, A HOOD DISPOSED UNDER SAID BUSHING FOR INSULATING THE NIPPLES FROM AMBIENT AIR AND SURROUNDING THE FIBERS IN THE COURSE OF THEIR FORMATION, SAID HOOD HAVING IN ITS LOWER PART AN ORIFICE FOR THE PASSAGE OF THE FIBERS, BLOWERS DISPOSED INSIDE SAID HOOD IN THE VICINITY OF THE NIPPLES AND CONES SO AS TO CREATE A CONTROLLED CIRCULATION OF FLUID FOR SECURING AN IDENTICAL COOLING FOR ALL THE NIPPLES AND CONES, AND MEANS FOR CONTROLLING THE FLUID IN RESPECT TO COMPOSITION, TEMPERATURE AND/OR QUANTITY, TO VARY THE DIAMETER OF THE FIBERS ISSUING FROM THE ORIFICE IN SAID HOOD.
