Abstract: The present invention relates to a method for producing a Mo-containing master alloy that is radiolucent. In accordance with the present invention, two elements may be used to reduce the density of a Mo-containing master alloy enough to make the master alloy radiolucent, aluminum or titanium. Aluminum is required in the particular titanium alloy in the same weight ratio as Mo and cannot be used to decrease the master alloy density without skewing the ratio. Since the master alloy is being added to a titanium melt, much more titanium can be used to reduce the master alloy density.

Abstract: The present invention relates to high-purity niobium monoxide powder (NbO) produced by a process of combining a mixture of higher niobium oxides and niobium metal powder or granules; heating and reacting the compacted mixture under controlled atmosphere to achieve temperature greater than about 1945° C., at which temperature the NbO is liquid; solidifying the liquid NbO to form a body of material; and fragmenting the body to form NbO particles suitable for application as capacitor anodes. The NbO product is unusually pure in composition and crystallography, and can be used for capacitors and for other electronic applications. The method of production of the NbO is robust, does not require high-purity feedstock, and can reclaim value from waste streams associated with the processing of NbO electronic components. The method of production also can be used to make high-purity NbO2 and mixtures of niobium metal/niobium monoxide and niobium monoxide/niobium dioxide.

Abstract: The present invention relates to high-purity niobium monoxide powder (NbO) produced by a process of combining a mixture of higher niobium oxides and niobium metal powder or granules; heating and reacting the compacted mixture under controlled atmosphere to achieve temperatures greater than about 1800° C., at which temperature the NbO is liquid; solidifying the liquid NbO to form a body of material; and fragmenting the body to form NbO particles suitable for application as e.g., capacitor anodes. The NbO product is unusually pure in composition and crystallography, highly dense, and can be used for capacitors and for other electronic applications. The method of production of the NbO is robust, does not require high-purity feedstock, and can reclaim value from waste streams associated with the processing of NbO electronic components.

Abstract: An additive for use in the desulfurization of molten iron is disclosed. The additive comprises a granular mixture of metallic magnesium, calcium oxide and a small amount of a hydrocarbon-containing material which provides a volatile gas producing component to the mixture. The hydrocarbon-containing material is preferably coal, carbon black, wood flour or a high density polyethylene. The additive is intended to be pneumatically injected into the melt in a stream of nonoxygenated carrier gas.

Abstract: A granular additive alloy designed for addition of calcium to molten steel to obtain maximum calcium effects with minimal additions, especially in steels which cannot tolerate the other elements commonly accompanying calcium additions. An alloy is described which contains a ratio of not more than 2.85:1 nor less than 0.35:1 calcium to aluminum, and can contain other reactive metals such as, but not limited to, rare earths, boron, titanium, and zirconium in amounts up to 40% by weight of the alloy. The preferred embodiment is an alloy with 60% by weight calcium and 40% by weight aluminum. The particles are intended to dissolve in the molten steel and form a boundary layer adjacent their surfaces. The particles are sized such that substantially all of the particle is consumed in the formation of this boundary layer, according to a given relationship based on the concentration of calcium and aluminum in the alloy.

Abstract: An axe comprising a blade formed of flat plate stock of generally uniform thickness, and a U-shaped handle attaching strap formed of flat plate stock of generally uniform thickness, the strap is fixedly mounted on a handle end portion with the bight portion and leg portions thereof substantially circumferentially surrounding the handle end portion and free end portions thereof extending therefrom in generally parallel relation beyond a leading edge of the handle end portion. The blade is rigidly mounted with its attaching portion disposed between the free end portions of the attaching strap and a trailing edge thereof facing the leading edge of the handle portion. The cutting edge of the blade is of uniform wedge-shaped cross-sectional configuration throughout its extent, the wedge shape being formed by generally straight bevel surfaces.

Abstract: A manual cultivator tool including a handle, a U-shaped blade, a tubular member provided with spaced flattened end portions having similar intermediately disposed bends therein, and a pair of separate handle attaching elements assembled into a final construction in which the tubular member interengages with the free ends of the legs of the U-shaped blade to form a strong annular structure and the attaching elements provide for both connection with the handle and the annular structure in such a way as to effect a limited tilting movement of the horizontal earth penetrating blade portion of the annular structure.
