Abstract: A reactor for continuously coating tow fibers has an outer tubular member, an inner support member spaced from the outer tubular member, a reactant flowing through a space defined by the outer tubular member and the inner support member, and at least one flow promotor located on an outer surface of the inner support member for directing the reactant towards an inner surface of the outer tubular member. A system and a method for coating tow fibers are also described.

Abstract: A powder processing apparatus includes a vessel. The vessel has an interior chamber that includes top and bottom regions, and a gas outlet to the exterior of the vessel. A wall divides the bottom region into first and second sub-regions, with the top region extending above the wall. First and second porous plates divide the first and second sub-regions such that there are first and second manifold regions below the first and second porous plates. The first and second gas manifold regions include first and second gas inlets from the exterior of the vessel.
