Abstract: A coating composition resistant to heat, flame and molten metal when applied as coating to a substrate. The composition includes an elastomeric binder and a particulate filler dispersed in the binder. The filler comprises particles of high aspect ratio in two dimensions relative to a third that co-operate when in a coating to provide a barrier within the binder. Also disclosed are an assembly comprising a substrate with a coating thereon, a fabric assembly resistant to spills and splashes of molten metal and a flame resistant building product.

Abstract: A yarn is spun by dividing a traveling fiber assembly into a plurality of fiber sub-assemblies, causing the sub-assemblies to traverse different paths and then recombining them, wherein the paths are sufficiently proximate for fibers to continuously transfer from one or more of the sub-assemblies and be drawn onto or into another or other sub-assemblies. Also disclosed is a method for forming a yarn comprising twisting a plurality of fiber sub-assemblies together at a convergence point to form a fiber assembly being a yarn, and further including cyclically altering the relative twist propagation in and/or into the sub-assemblies upstream of the convergence point. Still further disclosed are alternative methods involving cyclic variation of paths traversed by the sub-assemblies, and cyclic alteration of the relative positions of the sub-assemblies. Apparatus is described for carrying out each method.
