Abstract: Fibrous material webs and methods of making the fibrous material webs. Binderless webs can be formed in a continuous process where fiber material, such as glass is melted and formed into fibers. The fibers are formed into a web of binderless glass fibers or a web with a dry binder. The binderless web or the web with dry binder can be layered and/or the fibers that make up the web can be mechanically entangled, for example, by needling.

Abstract: Mechanically entangled, in-line formed, packs of glass fibers are mechanically entangled differently at different portions of the web. In one exemplary embodiment, in-line formed glass fibers are mechanically entangled by any combination of two or more entangling devices. The two or more entangling devices may be the same or different. In one exemplary embodiment, the glass fibers are mechanically entangled from at least a first side of a web by a first entangling device and are mechanically entangled from a second side of the web by a second entangling device.

Abstract: Cobalt based alloys which include chromium, nickel, tungsten, tantalum, zirconium, carbon and boron are provided which are suitable for forming spinners to be used in forming glass fibers. The alloys contain critically important amounts of carbon which maximizes the stress rupture life of the spinner alloy and minimizes the creep rate thereby making the alloy outstandingly adapted for glass manufacture.

Abstract: A mechanically alloyed composition of matter or alloy containing 30-40% chromium, 5-25% cobalt, 0.5-10% iron, 0.2-0.6% aluminum, 0.3-1.2% titanium, up to 0.15% carbon, about 0.2-1% yttria, up to about 0.3% nitrogen, the % titanium being at least about 1.4 times the % nitrogen, minor amounts of optional elements, the balance being essentially nickel. The consolidated and hot worked alloy with coarse grains produced by heat treatment at about 1300.degree. C. is useful in service requiring hot strength along with extraordinary resistance to oxidation, sulfidation and hot corrosive media. Specific utilization of the alloy of the invention is contemplated in handling molten glass and in utensils adapted to be used in contact with molten glass, e.g. spinners.
