Patent number: 9061936Abstract: Methods for substantially improving the stability of a melting furnace system including bushings and cooling apparatus for converting molten mineral material to continuous fibers is disclosed. Apparatus and methods for maintaining the molten material throughput and the electrical power load on fiberizing bushings substantially constant are disclosed. The orifice plate, with or without tips or nozzles, is subjected to a more rapid rate of heat removal after the bushing breaks out than it did while the bushing was in a desired fiberizing mode. Apparatus for blowing cooling air upward onto the orifice plate during the time the bushing is breaking out and/or hanging to provide additional cooling is disclosed along with optional additional or alternative apparatus to use for optional additional or alternative cooling is also disclosed.Type: GrantFiled: February 24, 2010Date of Patent: June 23, 2015Assignee: Johns ManvilleInventors: Terry Joe Hanna, Thomas Kent Thompson, Russell Donovan Arterburn

Patent number: 8820123Abstract: Fiberizing bushing assemblies, usually of rectangular shape, for fiberizing molten inorganic material like glass require cooling members located in the proximity of the orifices or tips forming the fibers. Cooling tubes carrying a cooling fluid like water are used by some fiber manufacturers and the cooling tubes have always been oriented with the length dimension of the bushing. It has now been discovered that orienting the cooling tubes to be substantially parallel to the width dimension, though more costly to fabricate because of the greater number required per bushing assembly, significantly reduce fiber break out rate and significantly increase productivity because they are easier to keep properly adjusted and result in a more uniform temperature of the fiberizing tips.Type: GrantFiled: October 12, 2006Date of Patent: September 2, 2014Assignee: Johns ManvilleInventor: Terry Joe Hanna

Patent number: 8056371Abstract: This invention involves apparatus and methods for making fibers by passing a molten material like glass, polymer, etc. through orifices or tips in a fiberizing bushing and then cooling the molten material coming from the tips and newly formed fibers using cooling tubes. The cooling tubes are made from precious metals and various alloys comprising precious metals, nickel and one or more of titanium, chromium, molybdenum, etc. The one or more fins attached to the top surface of a hollow tube to make the cooling tubes contain spaced apart gaps, notches and/or slots extending from the top edge of the fin to prevent warping of the fins and to make the cooling tube more bendable, adjustable during the operation of making fibers from molten material.Type: GrantFiled: April 5, 2010Date of Patent: November 15, 2011Assignee: Johns ManvilleInventors: Terry Joe Hanna, Thomas K Thompson, Walter Alexander Johnson, Russell Donovan Arterburn
