| Number | Title | Issue Date |
| 6367288 | Method and apparatus for preventing burner-hole build-up in fused silica processes In furnaces for producing high purity fused silica glass boules, glass particles have a tendency to build-up adjacent the burner hole rim. It was discovered that unburned furnace gases containing silica particles where re-circulated in the furnace close t... | 04/09/2002 |
| 5810902 | Method and apparatus for making air products In a process of making gas laid products by entraining particles including fibers at least partially coated with a binder in a gaseous stream, passing the stream through a forming chamber and through a permeable collecting surface where the particles incl... | 09/22/1998 |
| 4889546 | Method and apparatus for forming fibers from thermoplastic materials Method and apparatus for attenuating glass fibers. Primary glass is delivered into a primary, high temperature, high velocity gaseous blast to produce fibers that are attenuated while carried by said primary blast. While the fibers are above the minimum g... | 12/26/1989 |
| 4838917 | Process and apparatus for the production of very fine mineral fibers, in particular glass fibers The streams of melt issuing from the melt outlet apertures (18) at the bottom of a melting crucible (14) are broken up into fibers in a drawing nozzle by means of a blast medium directed substantially parallel to the streams of melt. The blast medium is p... | 06/13/1989 |
| 4818218 | Internal combustion burners This invention relates to internal combustion burners. In the burners according to the invention, the combustible mixture flows in counter-current to the combustion gases while in contact with the same, and the introduction of the mixture into the combust... | 04/04/1989 |
| 4553996 | Process for producing mineral wool fibers while reducing the velocity of flowing media A method for the reduction of the velocity of dispersions of fine particles in gas is described, in which the dispersion is divided into a plurality of mass flows M which are conveyed each to a subsonic diffuser to reduce the velocity from V1 t... | 11/19/1985 |
| 4487622 | Method and apparatus for forming fiber webs The invention concerns the improvement of the fiber distribution in a web or mat, the attenuation of the fibers being effected by means of gas currents. The material delivered in the form of filaments is attenuated in a channel between two gas jets. At th... | 12/11/1984 |
| 4268293 | Stabilization of glass feed in fiberization by toration Method and apparatus are disclosed providing both for separation of the components of a toration fiberizing center, including separation of both the glass stream supply means and of the secondary or carrier jet from the blast, and at the same time further... | 05/19/1981 |
| 4194897 | Method for making fibers from glass or other attenuable materials Method and apparatus for the production of fibrous materials from attenuable substances, particularly molten glass, are disclosed, along with the fiber products which result. In the disclosed system the material to be fiberized flows into a region establi... | 03/25/1980 |
| 4146378 | Fiber formation by use of gas blast attenuation Method and equipment are disclosed for forming fibers from attenuable material, such as molten glass, by the use of a jet penetrating transversely into a blast and by the of a structural element positioned adjacent to the path of the jet for establishing ... | 03/27/1979 |
| 4140509 | Method and apparatus for making fibers from thermoplastic materials Method and equipment are disclosed for forming fibers from attenuable material such as molten glass, by the use of high velocity whirling gas currents or tornadoes. Attenuation is preferably effected in two stages, the first of which utilizes a pair of hi... | 02/20/1979 |
| 4137059 | Method and apparatus for making fibers from attenuable materials The attenuation technique disclosed utilizes high velocity whirling currents or tornadoes formed in a toration zone i.e., a zone of interaction of a principle blast or current of gases and a gaseous carrier jet directed transversely into the blast. The ar... | 01/30/1979 |
| 4102662 | Method and apparatus for making fibers from thermoplastic materials Method and apparatus for the production of fibrous materials from attenuable substances, particularly molten glass, are disclosed, along with the fiber products which result. In the disclosed system the material to be fiberized flows into a region establi... | 07/25/1978 |
