Abstract: AIR INLET MATERIAL SEPARATOR      FOR CHIP CENTRIFUGE          ABSTRACT OF THE DISCLOSURE In a device for separating a liquid, as a cutting oil, from a mixture of metal chips and larger pieces of metal, such as bar ends and scrap, there is provided structure for preliminarily separating larger pieces of metal from the entire mass prior to the separation of the oil from the chips.  A centrifuge is provided having a drum with an intermediate perforated segment to permit the escape of oil therefrom while the chips move to the upper edge of the drum and thence outwardly to a receiving structure.  A chute is provided for feeding the mixture to be separated into the central portion of the drum and a strong stream of air is caused to flow therethrough into the centrifuge.  An opening is provided in the bottom of the chute intermediate its ends.  Thus, bar ends, and other large pieces of metal which may be included in said mixture, will drop through the opening while air being drawn into the chute through the opening by the centrifuge will entrain the metal chips to prevent their dropping out of the opening and continue onward through the chute into the centrifuge.

Abstract: Abstract A method and apparatus for enriching the iron carbonyl content of a recycle gas stream produced in an iron carbonyl decomposition or reaction process to enable reuse of the recycle gas stream in the iron carbonyl decomposition or reaction process by cooling the recycle gas stream, adding carbon monoxide to the recycle gas stream, compressing the recycle gas stream to a pressure of about 20 to about 38 atmospheres under conditions suitable to prevent substantial decomposition of residual iron carbonyl, and contacting the compressed gas stream at a temperature of about 65 to  about 160°C. with a reduced iron containing material in the presence of hydrogen sulfide under conditions suitable to produce substantially condensed iron carbonyl.  In a particu-larly preferred embodiment, the recycle gas stream is initially split into first and second portions, the first portion of the recycle gas stream is cooled, enriched with carbon monoxide, compressed and contacted with the reduced iron containing material to produce substantially condensed iron carbonyl, and at least a portion of the condensed iron carbonyl is vaporized and then combined with the second portion of the recycle gas stream to produce an iron car-bonyl enriched gas stream.  The iron carbonyl enriched gas stream may then be reintroduced into the iron carbonyl decomposition or reaction process.

Abstract: ABSTRACT      Process of converting alcohols, particularly ethanol, to other desirable products such as gasoline-boiling range hydrocarbons by contacting such with a dual functional zeolite catalyst in the presence of a sufficient level of water externally added to the reaction system in the range from 10 to 70 weight percent of the total reactant feed.   Products of such a conversion vary with the externally added water level, with conversion favoring an optimum gasoline-boiling range of hydrocarbons at an equal molar ratio to the reactant feed, and an increased amount of gaseous product from water levels substantially higher than said equal molar ratio thereof.  The so-called dual functional catalyst is such which induces simultaneous dehydration and recombination reactions of simple alcohol so as to result in the production of a spectrum of hydrocarbon moieties of the C1 to C10 family.
