Abstract: ABSTRACT         A crude alcohol-containing mixture comprising a sat-urated aliphatic alcohol of not more than 3 carbon atoms and associated impurities is processed to permit recovery of the desired alcohol product in highly concentrated and purified form.  In a first extractive distillation tower the crude feed is subjected to extractive distillation with water to remove substantially all the impurities overhead.  An aqueous bottoms stream from the first tower containing 5 to 10 wt. % alcohol and only minor amounts of impurities is fed to a second recti-fying tower where the alcohol product is concentrated and re-covered.  Stripped aqueous effluent is withdrawn from the bot-tom of the rectifying tower and is recycled in part to the first tower.  An aqueous alkali solution is introduced into the rectifying tower and regulated 80 that the concentration of alkali in the stripped aqueous effluent from the bottom of the tower is from about 0.10  to about 0.24 gram per liter. Overhead and intermediate purge streams containing low boiling and high boiling impurities may be removed from the rectifying tower and fed to a third tower along with the overhead from the first tower.  The impurities are recovered as by-products from the third tower, and an alcohol stream is recycled from the third tower to the first tower.

Abstract: ABSTRACT      Non-ferrous metals are recovered from metal bearing ores or other metal sources in substantially quantitative yields by treating a finely divided metal bearing material with an aqueous inorganic acid to form a slurry and baking the slurry at atmospheric pressure and at a temperature of about 350 to 800°C. or higher under quiescent conditions for a period of time sufficient to convert the non-ferrous metals into soluble salts.  The fumes from the baking process are scrubbed with a dilute acid solution to extract volatile metal salts.  The residue is leached with an appropriate solution or solutions to recover the soluble metal salts which are then recovered from the solution by conventional techniques.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for producing salted roasted nuts, as well as the products made according to this process.  Salted roasted nuts normally are obtained by roasting the optionally blanched nuts in an oil or air bath and subsequently mixing the optionally oil-wetted nuts with 0.5 to 2.5% dry common salt.  Experience has shown that fine granulated salt adheres badly to the surface of the roasted nuts and that a flake salt gives a better binding action.  Therefore, salting of nuts generally is accomplished with flakes which dissolve comparatively readily and exhibit a uniform size of particles and a higher degree of purity.  A disadvantage of salting roasted nuts with dry common salt is that even after roasting in oil the salt fails to adhere firmly enough to the nuts.  The rest of the oil will penetrate into the nuts, and the salt will tend to drop off.  This disadvantage can be avoided if, in making salted roasted nuts, the optionally shelled and/or blanched nuts are treated with an aqueous common salt solution before they are roasted in an oil or air bath.             .

Abstract: ABSTRACT OF THE DISCLOSURE   Synthetic hydrocarbon lubricating oils with very low pour points and low viscosities are produced by polymerizing alpha-olefins of from 5 to 20, preferably 10 to 14 carbon atoms, at temperatures in the range of 300° to 800°F in the presence of an acidic catalyst of the crystalline aluminosilicate zeolite molecular sieve-type.  The products are predomi-nantly of the paraffinic and napthenic hydrocarbon types.  Aromaticity can be introduced by polymerizing the olefins in the presence of aromatic hydrocarbons such as benzene.  The products are useful as lubricants in arctic climates and in other applications where low pour points are required, such as for transformer oils.

Abstract: Abstract of the Invention A subsurface froth generator with radial flow enhancers and surface skimmers comprises a shaft positioned concentrically in a draft tube.  An impeller on the shaft serves to pull gas and water into a submerged mixing zone.  A propeller on the lower end of the impeller shaft is rotated in the bottom of a still-well, below the draft tube, for pulling liquid upwardly toward the impeller.  A perforated shroud, having vanes on the top surface, arranged at the bottom of the draft tube is in substantially uninterrupted fluid communication with the impeller so that an upwardly circulating pattern of air bubbles entrained in the liquid by rotation of the impeller impinges directly on the undersurface of the shroud.  A circulation pattern of entrained air bubbles passing upwardly through the holes in the shroud and directed substantially radially upwardly and outwardly is produced.  The mixing unit generates a quiescent (non-turbulent) surface flow of foam which continuously moves in a radial direction toward skimmers.  The flow pattern reduces the possibility of re-entrainment of floated material or stagnation or dissolution of the entrained air bubbles.

Abstract: ABSTRACT        An improved method and structure for producing narrow openings to the surface of a first material processing a first set of etch characteristics is disclosed.  The method includes the step of forming on a portion of the surface of the first material an etchable mask having a first narrow-opening-forming lateral edge disposed along a selected edge of the to-be-formed narrow opening.  A protective layer of a second material possessing a second set of etch characteristics is next formed on the exposed surface of the first material, the protective-layer having a second narrow-opening-forming lateral edge juxtaposed the first narrow-opening-forming lateral edge. The first narrow-opening-forming lateral edge on the mask   is then etched to expose unprotected areas of the first material-thereby producing the narrow opening to the surface of the first material.  The method and structure of the invention is particularly well suited for producing fine geometry patterns in solid state device structures.
