    摘要： SYNTHETIC OR NATURAL CRUDE OILS OF LOW INORGANIC SALTS AND LOW SULFUR CONTENT MAY BE USED AS FUELS FOR OPERATING HEAVY DUTY DIESEL ENGINES WHERE THESE CRUDE OILS CONTAIN AT LEAST 0.01 AND UP TO ABOUT 2.0 WT. PERCENT, OR AT LEAST A SUFFICIENT AMOUN ABOVE 0.01 WT. PERCENT TO APPRECIABLY MINIMIZE OR PREVENT CARBON DEPOSITION IN AND ON THE FUEL INJECTORS, OF AT LEAST ONE OVERBASED ALKALINE EARTH METAL SULFONATE AND/OR THE CONDESATION PRODUCT OF AN ALKYLENE POLYAMINE WITH ORGANIC MONO OR DICARBOXYLIC ACIDS OR ANHYDRIDES THEREOF, WHEREIN THE ACIDS OR ANHYDRIDES HAVE SUBSTITUTED THEREIN A LONG CHAIN ALKENYL GROUP OF C40-C250, EITHER OR BOTH ADDITIVES BEING USED AS DISPERSANTS. SULFUR CONTENT OF THE CRUDE OIL SHOULD BE BELOW ABOUT 1.0 WT. PERCENT AND SALT CONTENTS SHOULD BE BELOW ABOUT 3 POUNDS PER THOUSAND BARRELS OF CRUDE OIL. THE CRUDE OIL MAY BE OF PARAFFINIC, ASPHALTIC OR MIXED TYPE.

    摘要： THIS INVENTION PROVIDES A METHOD FOR TREATING A DYEABLE POLYOLEFIN FIBER BEFORE A DYEING STEP, WHICH COMPRISES CONTACTING THE DYEABLE POLYOLEFIN FIBER WITH A SPECIFIC LIQUID TREATING FLUID. THE FLUID CONSISTS ESSENTIALLY OF 100 PARTS BY WEIGHT MADE UP AS FOLLOWS: FROM 98 TO 80 PARTS BY WEIGHT OF ACETIC ACID HAVING A CONCENTRATION FROM 40 WEIGHT PERCENT AQUEOUS TO GLACIAL, AND FROM 2 TO 20 PARTS BY WEIGHT OF AN ACID CHOSEN FROM THE GROUP CONSISTING OF SUBSTANTIALLY WATER INSOLUBLE C8 TO C12 ALKANOIC ACIDS. THE TREATING CONDITIONS INCLUDE A PRESSURE SUFFICIENT TO MAINTAIN THE TREATING FLUID IN THE LIQUID PHASE, A TEMPERATURE FROM ABOUT 75*F. TO ABOUT 175*F. AND A TREATING TIME FROM ABOUT 1 MINUTE TO ABOUT 5 MINUTES. SUITABLY, THE TREATING STEP IS FOLLOWED BY CONVENTIONAL ACID DYEING.

    摘要： A roll-type press for compressing particulate metal powders, especially ferrous metal powders such as produced in direct iron ore reduction processes, to provide series, or strings, of readily separable briquettes as articles of manufacture. The mold pockets in the faces of the two cooperating rolls are so arranged that they partially overlap as the pockets of one roll come into contact with the pockets of the other. The overlapping section, or junctures, of the compacted briquettes are less densely compacted than those conventionally produced so that the individual briquettes of the issuing series can be readily broken apart. Moreover, forces are generated which aid in the release of the briquettes from the mold pockets.

    摘要： THIS INVENTION RELATES TO THE RECOVERY OF C6 THROUGH C30 ALKYL CARBOXYLIC ACIDS FROM A MIXTURE OF OXIDATION PRODUCTS WHICH ARE FORMED BY THE REACTION OF AN OLEFIN WITH CARBON MONOXIDE AND HYDROGEN IN THE PRESENCE OF AN OXONATION CATALYST, I.E., COBALT, AND THEREAFTER OXIDIZING THE OXONATION PRODUCT MIXTURE WITH MOLECULAR OXYGEN TO FORM THE OXIDATION PRODUCT MIXTURE. THE OXIDATION PRODUCT MIXTURE, CONTAINING CARBOXYLIC ACIDS, OXIDES OF SAID OXONATION CATALYSTS AND OXIDATION BY-PRODUCTS IS REACTED IN A FIRST STAGE WITH SULFUR-DIOXIDE IN THE PRESENCE OF WATER TO CONVERT THE OXIDES OF SAID OXONATION CATALYST TO WATERSOLUBLE CATALYST SULFATES DISSOLVED IN AN AQUEOUS PHASE. THEREAFTER, TSHE AQUEOUS PHASE FORMED IN THE FIRST STAGE IS SEPARATED FROM THE NON-AQUEOUS PHASE CONTAINING THE CARBOXYLIC ACIDS AND THE OXIDATION BY-PRODUCTS, AND THE LATTER REACTED WITH A DILUTE AQUEOUS ALKALI, WHEREBY THE CARBOXYLIC ACIDS ARE RECOVERED AS AN AQUEOUS SOLUTION OF ALKALI CARBOXYLATES AND THE OXIDATION BY-PRODUCTS SEPARATE AS AN ALKALI-INSOLUBLE PHASE.
