    Abstract: Metal strip may be cast directly from molten metal (18) in an open tundish (16) onto a chill roll (10). Strip thickness is controlled by contouring the tundish lip (32) with an offset near the casting wheel. This can be used remedially to offset the natural tendency for the strip to be thicker near the edges, which is undesirable for cold rolling, or it may be used creatively to produce contoured strip.

    Abstract: Method and apparatus are described for producing a fine, narrow size distribution metal powder. The method involves the two stage breakup of a liquid metal stream (4). A first stage breaks the liquid into moderate size droplets or ligaments (6) and delivers them, still in the liquid state, to a second stage. The second stage is a rapidly spinning cup (7) having a rotating water wall (8) which shears the droplets or ligaments from the first stage into very fine powder.

    Abstract: Metal strip may be directly cast by deposit of a melt layer onto a chill surface. Quality of both the upper and lower surfaces of strip cast in this manner may be substantially improved according to the invention by casting on a chill roll (2) having fine, circumferential, surface grooving (32, 33, 41, 42) of a particular geometry.

    Abstract: Process for producing high purity aluminum nitride by reacting aluminum sulfide with gaseous ammonia or gaseous nitrogen and hydrogen at a temperature above 1100 C. When using gaseous ammonia the preferred reaction conditions are at about 1200 C to 1500 C and at about atmospheric pressure for about 2-30 hours. When gaseous nitrogen and hydrogen are used the preferred reactin conditions are at about 1200 C to 1750 C and at pressures above atmospheric for about 2-30 hours. A high purity, low oxygen containing, free flowing powder is produced.

    Abstract: Molten material, especially metals, can be formed directly into fiber by allowing a stream of molten material to flow across a ramp member (12), thereby forming a thin layer (20) of molten material, under sustantially no hydrostatic pressure. At an outlet end of the ramp member, a wheel (24) bearing a plurality of ridges passes through the thin layer (20) of molten material thereby drawing out a plurality of filaments. The apparatus avoids the problem of strip formation encountered in prior art apparatus using a plurality of closely spaced ridges.
