Abstract: ABSTRACT OF THE DISCLOSURE                Process for the conversion of carbohydrates to polyhydric alcohols.  Carbo-hydrates, such as corn starch hydrolyzate, glucose, and invert sugar, are converted to polyhydric alcohols by hydrogenation at high pressure in the presence of a ruthenium-containing alumino-silicate zeolite catalyst in which the silica/ alumina mol ratio is greater than three, and in particular ruthenium on a Y type zeolite in the hydrogen form.  This acid stable catalyst gives good conversion with high selectivity to sorbitol when corn starch hydrolyzate in aqueous solution is used as the starting material.

Abstract: METHOD OF RECOVERING GLASS CULLET              ABSTRACT OF THE DISCLOSURE      A method of recovering cullet from laminated glass scrap is disclosed.  The laminated scrap is crushed to fragment the glass but the glass generally remains in bonding contact with the laminating interlayer.  The crushed scrap is mixed as its temperature is increased so that the laminating interlayer softens to permit the interlayer to be torn thus reducing the size of the scrap. The finally divided scrap is heated to a temperature at which the interlayer burns away.  Any carbon residue left on the crushed scrap is also burned away.  The crushed scrap is cooled and recovered as cullet.

Abstract: Abstract of the Disclosure This invention relates to a process of recovering copper from a sulfur and iron containing ore of the same.  The process consists of the steps of a) forming an aqueous nitric acid leach solution of the ore; b) heating the solution under containment to a temperature at or above the melting point of sulfur to establish an iron content of no greater than 15 grams of iron values per liter in the leach liquor; c) adding an acid neutralizer to the liquor to establish a pH of about 1-2 therein and to produce salts of the acid which are soluble in the liquor; d) contacting the liquor with a copper specific aqueous insoluble organic extractant liquid while maintaining the foregoing pH in the liquor to extract the copper into the extractant liquid; e) relatively separating the organic extractant liquid and the liquor; and f) recovering the copper from the organic extractant liquid.  The extractant will extract the copper into the extractant liquid without the problem of insoluble metal hydroxides and/or other insoluble metal and acid neutralizer salts scanning in the liquor.
