Abstract: Catalyst support systems for ammonia oxidation burners comprising a top flange and an inner wall. The top flange comprises a planar section, a rounded outer edge, and a rounded inner edge, the rounded outer edge and the rounded inner edge being separated by the planar section. The inner wall comprises a carrier plate, a gauze shelf, and a bottom plate shelf, the gauze shelf and the bottom plate shelf being attached to the carrier plate. The carrier plate is attached to the top flange by means of the rounded inner edge.

Abstract: A method for producing a weldable titanium alloy and/or composite wire. The method includes: a) forming a green object by blending particulates of titanium sponge with one or more powdered alloying additions and cold compacting the blended mixture and subjecting the blended mixture including lubricant to pressure; b) forming a work body of alloyed titanium by heating the green object in a protected atmosphere and holding the temperature for a period of at least 4 hours, and then hot working the green object at a temperature of less than 200° C. apart from the beta transition temperature of the titanium alloy and shaping the green object to obtain an elongated profile; and c) forming the welding wire by placing the elongated profile of the work body in a rolling mill having one or more rolls disposed in series.

Abstract: A process for producing a weldable titanium or titanium alloy wire characterized in that full consolidation of the wire is achieved via solid-state processing entailing compaction, extrusion, and rolling, whereby melting of the constituent titanium sponge particles does not occur.

Abstract: This invention describes a method of producing a metal, M1, in an electrolytic cell consisting of a molten electrolyte, MZY-MZO, at least one anode and at least one cathode, characterised in that the passage of current between said anode(s) and cathode(s) through said electrolyte, produces a metal, M1, from a raw material, M1X, containing a non-metallic species, X, under conditions such that the potential at the cathode causes the reduction of the MZ cation and the formation of MZ at activities less than one, and the potential at the cathode is insufficient to cause formation of MZ metal as a discrete solid or liquid phase, and the MZ so produced reduces the raw material, M1X, at the cathode, to M1.
