20080236722 | Fibrous product and method and apparatus for making the product - A nonwoven fibrous insulation product has at least a bi-modal fiber diameter distribution designed to provide the product with selected thermal insulating and physical performance properties that are affected by fiber diameter such as rigidity and recovery properties. The product is made by: forming two or more fiber groupings that each have a selected fiber diameter distribution with a selected mean fiber diameter wherein the selected fiber diameter distributions of the fiber groupings differ from each other. The fibers of the fiber groupings are intermingled and entangled together in selected percentages by weight to form a product with a selected density and thickness that exhibits selected product performance properties based on the properties of the fiber groupings and the relative percentages by weight of the fiber groupings. | 10-02-2008 |
20080250818 | Fiberizing bushing and method for fiberizing molten material - Fiberizing bushings for fiberizing molten materials including molten glass are heated by applying a voltage drop across the bushings wherein molten material flows through an array of hollow tips attached to, or integral with, a tip plate having orifices therein that generally align with channels through the hollow tips to form fibers. The uniformity of the diameter of the fibers produced is much improved by using tips of different lengths and/or tips having channels of differing ID's to compensate for unequal electrical heating and/or cooling effects of drawn-in ambient air that cools the tips on the extreme outer periphery and/or cooling or heating effects of external supports or cooling members running through the array of tips that cools or heats adjacent tips more than the interior tips. | 10-16-2008 |
20100064734 | Transverse row bushing support - According to the invention, a system for forming glass fiber from molten glass is disclosed. The system may include a tip plate, a plurality of tips, and a plurality of support members. The plurality of tips may include a plurality of rows of tips. Each of the plurality of support members may support the tip plate. Each of the plurality of support members may be located between two of the plurality of rows of tips. | 03-18-2010 |

20120000250 | TRANSVERSE ROW BUSHING SUPPORT - According to the invention, a system for forming glass fiber from molten glass is disclosed. The system may include a tip plate, a plurality of tips, and a plurality of support members. The plurality of tips may include a plurality of rows of tips. Each of the plurality of support members may support the tip plate. Each of the plurality of support members may be located between two of the plurality of rows of tips. | 01-05-2012 |
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 |
20120297839 | TRANSVERSE ROW BUSHINGS HAVING CERAMIC SUPPORTS - A bushing system includes a bushing having a bottom plate with a plurality of holes from which filaments are drawn. At least one elongated support extends through the bushing generally along a longitudinal axis to hold and stabilize the bushing. To handle the harsh conditions under which the bushing is subjected, the support comprises an alumina-based ceramic that generally resists sagging or excessive expansion and contraction during heating and cooling. | 11-29-2012 |
