| 20100313606 | METHOD FOR PRODUCING FIBERS FROM ROCKS AND A PLANT FOR CARRYING OUT SAID METHOD - The invention relates to a method and a plant for producing fibers from molten rocks such as basalt, diabase, amphibolite, andesite, dacite, granite and rhyolite. The inventive method involves rock crushing for producing grains of a specified size, charging the crushed rock into a melting zone and drawing fibers from the melt. The melting zone is extended along the vertical axis. The sized grains successively fall under gravity into the melting zone and the fibers are drawn from each sized grain melt. The drop rate of each sized grain into the melting zone is limited by the upward flow of a hot gas-air mixture. The plant comprises a rock crushing device and melting device with a melting zone whose outlet is connected to the discharge orifice with a bushing assembly and a device for fiber winding at the output. The plant includes a funnel at the outlet of the rock crushing device rotatable around the vertical axis. | 12-16-2010 |
| 20110100065 | Terminal Clamp for Horizontal Ear Bushing - A terminal clamp assembly for a fiberizing bushing includes a clamp body having a firsts end face and a lower jaw, an auxiliary heat sink body selectively displaceable with respect to the clamp body, a contact assembly carried on the auxiliary heat sink body and an actuator to displace the heat sink body toward or away from the face of the clamp body. The invention also includes a bushing assembly incorporating the terminal clamp assembly and an expansion compensating mounting bracket for the clamp assembly. | 05-05-2011 |
| 20120297838 | TRANSVERSE ROW BUSHINGS AND METHODS WITH FREEDOM OF MOVEMENT - An exemplary bushing systemutilizes a bushing having a bottom plate having a plurality of holes from which filaments are drawn, and a plurality of support-receiving elements that are each configured to receive an elongated support. The support-receiving elements extend through the bushing generally along a longitudinal axis. A frame supports the bushing and includes a pair of horizontal rails upon which the supports rest. The horizontal rails comprise a treated surface that permits movement of the elongated supports relative to the frame in the longitudinal direction as the bushing expands and contracts due to thermal heating and cooling. | 11-29-2012 |

| 20090193852 | Automatic Strand Take-Up Installation - The automatic strand take-up installation comprises at least one gripping member ( | 08-06-2009 |
| 065481000 | Cooling of molten glass at forming area (e.g., cooling fins, etc.) | 4 |
| 20100186454 | COOLING MEMBERS FOR FIBERIZING BUSHINGS AND METHOD - 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. | 07-29-2010 |
| 20110079051 | HIGH EFFICIENCY FIN ASSEMBLY FOR MAKING GLASS FIBERS - Cooling fin assemblies constructed of materials suitable for use in manufacturing glass filaments are provided. The cooling fin assemblies include a manifold having a first end, a second end and an internal passage therebetween. The internal passage is configured for a flow of cooling fluid. A plurality of baffles is positioned within the internal passage. A plurality of blades is connected to the manifold. The blades are configured to conduct heat to the manifold. The baffles are configured to create a serpentine flow path for the cooling fluid within the manifold. | 04-07-2011 |
| 20110185771 | ADJUSTABLE POSITIONING APPARATUS FOR COOLING MEMBERS AND METHOD - An apparatus for adjusting the cooling members located beneath fiberizing bushings is disclosed having the capability of moving each cooling member, or one portion of each cooling member, in a generally vertical direction, and/or in a lateral and/or tilting direction. Also disclosed is a process of using the apparatus to make fibers from molten material including molten glass. | 08-04-2011 |
