Abstract:
A system and method of producing an elemental material or an alloy from a halide of the elemental material or halide mixtures. The vapor halide of an elemental material or halide mixtures are introduced into a liquid phase of a reducing metal of an alkali metal or alkaline earth metal or mixtures thereof present in excess of the amount needed to reduce the halide vapor to the elemental material or alloy resulting in an exothermic reaction between the vapor halide and the liquid reducing metal. Particulates of the elemental material or alloy and particulates of the halide salt of the reducing metal are produced along with sufficient heat to vaporize substantially all the excess reducing metal. Thereafter, the vapor of the reducing metal is separated from the particulates of the elemental material or alloy and the particulates of the halide salt of the reducing metal before the particulate reaction products are separated from each other.
Abstract:
The present invention provides compounds of Formula I: wherein Ar1 is aryl or heteroaryl, Ar2 is aryl or heteroaryl, and R is a suitable organic group. Herbicidal composition comprising such active compounds, and methods for controlling undesirable plants by applying such compounds, are also described.
Abstract:
A wheel lift-assist frame comprises a pair of support beams, which may be coupled with a tillage machine at first ends, each beam to the left or right of the center of the tillage machine respective and running rearward of the tillage machine. The support beams may also be coupled with a planter. A cross beam is coupled with the support beams at second ends thereof. A plurality of wheel assemblies are fixed to the cross beam at points such that the wheels run between rows created by the tillage machine.
Abstract:
A coolant tube and electrode are adapted to mate with each other to align the tube relative to the electrode during operation of the torch. Improved alignment ensures an adequate flow of coolant along an interior surface of the electrode. In one aspect, an elongated body of the coolant tube has a surface adapted to mate with the electrode. In another aspect, an elongated body of the electrode has a surface adapted to mate with the coolant tube. The surfaces of the tube and electrode may, for example, be flanges, tapered surfaces, contours, or steps.
Abstract:
A system and method of separating metal powder from a slurry of liquid metal and metal powder and salt is disclosed in which the slurry is introduced into a first vessel operated in an inert environment when liquid metal is separated from the metal powder and salt leaving principally salt and metal powder substantially free of liquid metal. The salt and metal powder is transferred to a second vessel operated in an inert enviroment with both enviroments being protected from contamination. Then the salt and metal powder substantially free of salt and liquid metal. The method is particularly applicable for use in the production of Ti and its alloys.
Abstract:
The invention features methods and systems for treating inflammatory, proliferative skin disorders such as psoriasis, with ultraviolet phototherapy. The methods and systems use optical techniques to scan a patient's skin, designate areas of affected skin, and selectively deliver high doses of phototherapeutic ultraviolet radiation to the designated areas. To insure that only affected areas of skin affected are designated for the high doses of UV radiation, the methods and systems use one or more optical diagnostics that relate to independent physiological features of affected skin.
Abstract:
A communication system including an antenna array with feed network coupled to communication electronics. In one example, a communication subsystem comprises a plurality of antennas each adapted to receive an information signal and a plurality of orthomode transducers coupled to corresponding ones of the plurality of antennas, each OMT is adapted to provide at a first component signal having a first polarization and a second component signal having a second polarization. The communication subsystem also comprises a feed network that receives the first component signal and the second component signal from each orthomode transducer and provides a first summed component signal at a first feed port and a second summed component signal at a second feed port, and a phase correction device coupled to the first and second feed ports and adapted to phase match the first summed component signal with the second summed component signal.
Abstract:
An aqueous printing fluid, comprising a cosolvent, the cosolvent or mixture of compounds comprising at least one inner salt compound having a sp3-hybridized nitrogen cation and an associated anionic charge either isolated on an N-substituted oxygen anion bound directly to the sp3-hybridized nitrogen cation or isolated among the oxygens of a carboxylate group; a method of avoiding paper curl in printed paper by using the above-described aqueous printing fluid; and a printer system for avoiding paper curl in printed paper through using the above-described aqueous printing fluid.
Abstract:
The present invention provides particles that create permanent tissue markings, including, but not limited to, tattoos, that have variable appearance properties. Also, the present invention provides methods for producing, implanting, altering and removing these variable appearance tissue markings.
