  • Patent number: 8056371
    Abstract: 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.

  • Patent number: 8057881
    Abstract: A fungi resistant asphalt is combined with a base sheet to form a fungi resistant asphalt containing sheet material. Typically, the base sheet is a fibrous base sheet that, by itself, may or may not be fungi resistant. The fungi resistant asphalt is at least partially absorbed by the base sheet to form the fungi resistant asphalt containing sheet material and typically forms one or both major surfaces of the fungi resistant asphalt containing sheet material.

  • Patent number: 8006519
    Abstract: 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.

  • Patent number: 8003170
    Abstract: A system for controlling the residual moisture in pre-cured binder coated glass fibers. The moisture of the binder coated glass fibers is measured after the process water is extracted in a collection box. Based on the level of moisture found in the coated glass fibers, adjustments are made to the process upstream of the moisture measurements. The adjustments include, but are not limited to, adjusting the amount of water used to make the binder composition; adjusting the amount of heat applied to the binder composition as it is applied to the glass fibers and adjusting the vacuum conditions used to extract the process water from the binder coated glass fibers. Control of the residual moisture in the precured binder coated glass fibers helps ensure proper curing of the binder during the subsequent curing step.
