| 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 |
| 20090277126 | Rolled sheet product - A rolled sheet product, the sheet product comprising a top layer and a bottom layer, the top layer being less ductile than the bottom layer, and the top layer facing outward in the rolled sheet product. A method of packaging a sheet product comprising a top layer and a bottom layer, the top layer being less ductile than the bottom layer, comprising winding the sheet product into a roll such that the top layer faces outward. | 11-12-2009 |
| 20100001422 | Method of measuring extent of cure of binder in products - A method for determining the extent of cure of binder in a product comprising heating a sample of the product to vaporize free moisture in the sample and expel vaporized free moisture from the sample, measuring cure moisture content of the product, measuring binder content of the product, calculating a product ratio of cure moisture content to binder content, and comparing the product ratio of cure moisture content to binder content to a predetermined desirable ratio of cure moisture content to binder content. | 01-07-2010 |
