Abstract: A string-bridge interface system includes a plurality of string-bridge interface units to provide coupling between strings of a musical instrument and one or more sound bridges of the musical instrument, which are further coupled to the sound board of the musical instrument. Such coupling provided by the string-bridge interface units allows for reduced loading of the sound board and more direct routing of the strings.

Abstract: An extraction process for extracting ionic values from an aqueous solution containing same which comprises contacting the aqueous solution with an organic hydrophobic liquid extractant phase comprising an extractant for ions, the molecules of which extractant contain at least one hydrophobic group selected from cyclic phosphazene radicals, linear siloxane radicals, cyclic siloxane radicals, and three-dimensional siloxane radicals, and stripping resulting loaded extractant phase with an aqueous stripping liquid phase.

Abstract: A combined feed tube and continuous casting mould comprises a copper mould having a refractory feed tube projecting into the inlet end of the mould passage. The feed tube is in abutting relation with the wall of the mould passage and the material from which the feed tube is formed is one which has a low coefficient of friction such as graphite. The portion of the feed tube in the mould provides the surface on which the initial freezing of the molten metal occurs and this surface is cooled by its contact with the mould.

Abstract: The invention concerns making metal powder by atomizing and quenching a stream of molten metal. According to the invention an anti-foaming agent is included in the atomizing and/or the quenching liquid and this produces more rapid cooling of the metal particles.

Abstract: An atomizer for making powder of the type in which an atomizing chamber above a water bath container defines a path for a falling stream of molten metal and nozzles supply downwardly directed opposed ribbon sectioned jets of water at an angle to the vertical to impinge on the metal stream and atomize it. The atomized particles are then quenched by further water. According to this invention there are two pairs of opposed nozzles on lines mutually at right angles arranged so that the jets from the first pair intersect at a level above the level of intersection of the second pair. The jets from the first pair form the metal stream into a ribbon section in a plane containing the second pair of nozzles and the jets from the second pair atomize the stream.According to another feature the energy of the water flow of these jets is used to induce a circulating secondary flow of quench water in the atomizing zone thus eliminating the need for a purged supply of quench water.

Abstract: An integrated process for the recovery of copper from impure copper bearing materials is provided by leaching the copper bearing material with sulfuric acid to convert the copper value to the soluble copper sulfate, selectively extracting the copper value from the leach liquor by contacting the liquor with an organic extractant stripping the copper from the organic copper extractant by contacting with liquor of enhanced acid content resulting from a subsequent reduction step, thus regenerating the organic extractant, contacting and thus reacting the acidified copper containing solution with an organic solution of amine extractant to reduce its acid concentration to a desired level, and recovering the copper metal by reacting the copper containing solution of lowered acid content with sulfur dioxide.
