Abstract: An electrically operated displacement pump includes an electric motor having a stator and a rotor. The rotor is connected to the fluid displacer to power pumping by the fluid displacer. A cooling circuit extends at least partially about an exterior of a motor housing that houses the electric motor. A fan assembly blows cooling air through the cooling circuit.

Abstract: A system for inspecting a wire segment includes an inspection apparatus and a visual imaging device. The apparatus includes an array of mirrors positioned about a centerline of the apparatus, wherein each mirror in the array is oriented such that a reflection of a first inspection zone of the wire segment in the array of mirrors forms a circumferential view of the first inspection zone of the wire segment, and the reflection from each mirror is within a field of view from a single vantage point. The visual imaging device is positioned at the single vantage point and oriented towards the wire segment such that the reflection from each mirror of the array of mirrors is within a field of view of the visual imaging device, the visual imaging device configured to capture at least one image of the reflection of the wire segment from the array of mirrors.

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: Vanadium-aluminum master alloys with small amounts of refractory metals such as ruthenium, are made substantially free of refractory inclusions and with a substantially homogeneous microstructure by reacting vanadium oxides with excess aluminum through an aluminothermic reduction reaction in the presence of the refractory to yield the desired master alloy. A preferred homogeneous vanadium-aluminum-ruthenium alloy without inclusions contains from about 59 to 70% of vanadium, about 29 to 40% of aluminum, and about 1 to 10% of ruthenium, all based on the weight of the alloy. The substantially homogeneous and inclusion-free master alloy is then used to produce titanium base alloys of higher quality, such as 4% vanadium and 6% aluminum titanium base alloys containing small amounts of refractory metals, usually containing from about 0.1 to 1.0% of ruthenium.

Abstract: Disclosed is a process for dissolving tantalum and/or columbium-containing materials contaminated with alkali metal impurities. The tantalum and columbium materials are digested in a solution comprising hydrofluoric acid and a fluosilicate-containing compound. The alkali metals are reacted to form precipitated fluosilicates, which then can readily be separated.
