Abstract: A method of fabricating intermetallic compounds of TiAl and TiAl.sub.3 into shapes including a foil utilizing an arc spray process in which bimetalic titanium aluminum or low titanium aluminum and low aluminum titanium wires of the proper proportions are used to form an intermetallic compound overlay, which is densified to form the shape.

Abstract: A method of making a tungsten tantalum material comprising generally 80 percent by weight tungsten and 20 percent by weight tantalum and forming the material into a high strength full density round bar, which can be utilized in a high velocity armor penetrator.

Abstract: A method of improving an arc spray process for making metal matrix composite monotapes by providing an AC power supply and individually controlled wire feeds to promote even melting of the wires particularly wires formed of metals and alloys having high temperature melting points.

Abstract: An improved waste heat boiler having a front, back and two side walls that cooperate to form a flue with a rotary combustor for burning municipal solid waste extending through the front wall and an asymmetrical bull nose protuberance disposed on the back wall above the rotary combustor and a plurality of nozzles disposed in the side walls or the front wall aligned with the tip of the protuberance to direct jets of air inwardly and downwardly into the flue to reduce the CO content of the exhaust gases from the waste heat boiler.

Abstract: A process for recycling steel belted tires by shredding the tires in multiple stages and separating the rubber from the rubber encrusted steel until the rubber encrusted steel is about 50% steel and charging a plasma fired cupola with the rubber encrusted steel, coke, and limestone, melting the steel and adding dolomite as a desulfurizing agent in the plasma torch feed nozzle to make a low sulfur iron.

Abstract: An inclined combustion barrel for a rotary combustor utilized to burn municipal solid waste wherein the combustion barrel is formed from a plurality of parallel cooling pipes disposed in a circular array with a plurality of spaced apart flat plates disposed between adjacent cooling pipes in descending order with overlapping ends and side margins welded to the cooling pipes to form a web between the cooling pipes which provide influent air flow and extends the life of the web.

Abstract: A method of fabricating irregular shapes wrapped with metal matrix composite monotape utilizing a cylindrical deposition drum wrapped with a spiraling array of evenly spaced strands of high strength fibers and overlaid with a metal matrix, which is cut into a narrow ribbon which is transferred to a spool and then wound on the irregular shape in a helical manner so that the opposite side margins are adjacent each other in adjacent turns.

Abstract: A method of desulfurizing iron in a plasma fired cupola having a plurality if feed nozzles each of which have a particulate feed and a plasma torch connected thereto; a fluxing agent such as CaO, MgO, CaCO.sub.3, MgCO.sub.3 or CaCO.sub.3 MgCO.sub.3 is fed to the feed nozzle and melted by the plasma torch; the molten fluxing agent mixes directly with the molten iron in the cupola and reacts with the sulfur in the iron; the reacted and unreacted fluxing agent combine with the slag reducing the viscosity making the slag flow better and producing a low sulfur iron in the cupola.

Abstract: A damping system for a fabricated gear comprising a plurality of viscoelastic sheets sandwiched between damping plates and side plates, the side plates having circumferential rings which act as mode converters to change in-plane vibration to bending mode vibrations and are fixed to one margin of the damping plate to provide effective vibration damping within the gear.

Abstract: A plasma-fired cupola may be operated at very low gas flow levels in the range of 0.9 SCFM per sq. inch of cupola cross-sectional area and with recirculated off-gas substantially reducing the rate at which coke is burned thus reducing the sulfur content of the iron produced also alloying elements may be added as ferrous-alloys or as alloy oxides through the plasma torch with or without recirculated off-gas and/or pulverized coke to rapidly change the chemical composition of the iron being formed.

Abstract: A method of determining the runout of a shaft which includes combining the signals from two linear variable differential transformers and a resolver in a computer to provide a visual or machine readable representation of the deviation of the outer peripheral portion of a shaft from that of a true cylindrical portion.

Abstract: A redundant locking system for the closing blades of a circular array of curved Christmas tree-shaped roots of side entry freestanding steam turbine blades which have registering holes in the platform of the closing blades and the blades adjacent to the closing blades which receive pins, the pins fit tightly into the through holes and loosely into the hole in the adjacent blade to lock the closing blades in place and allow each blade to vibrate independently.

Abstract: A circular array of rotatable blades formed from blades having an integral shroud with a leading planar surface and a trailing planar surface, the leading planar surface being generally parallel to an axial radial plane passing through the center of the root of the blade and the trailing planar surface, if extended, intersecting the axial radial plane passing through the center of the root of the blade to form an angle generally equal in degrees to 360 divided by the number of blades forming the circular array.

Abstract: A moisture separator which incorporates an inner cylinder disposed in coaxial relation with an exhaust pipe of a steam turbine utilizes the spiral secondary flow of a gas stream to remove liquids which are entrained therein. The moisture separator incorporates an inner cylinder which has one or more apertures through its wall. The inner cylinder is placed in coaxial relation with the exhaust pipe of a steam turbine with means for sealing the axial ends of an annular chamber formed between the cylinder and the exhaust pipe. Means are provided for dividing the annular chamber into a plurality of arcuate spaces and for removing liquid which collects within each of the arcuate spaces. The moisture separator utilizes the characteristic of gas streams which creates spiral secondary flows when forced to turn around a bend. The spiral flows cause liquid, which is entrained in a gas stream, to migrate to the inner surface of a pipe or cylinder and coalesce on the walls thereof.
