1. IN THE METHOD OF TREATING A LIQUID FEED COMPRISING A MORE VOLATILE AND A LESS VOLATILE FRACTION TO SEPARATE SAID FRACTIONS THE STEPS COMPRISING (1) MOVING SAID LIQUID FEED VERTICALLY THROUGH A SUBSTANTIALLY VERTICAL EVAPORATION CHAMBER HAVING THEREWITHIN A CONDITION OF SUBSTANTIALLY PROGRESSIVELY INCREASING TEMPERATURE IN THE DIRECTION OF SAID LIQUID FEED MOVEMENT AND MOVING CONCURRENTLY THEREWITH AND IN CONTACT THEREWITH A CARRIER GAS THEREBY TO PROGRESSIVELY HEAT SAID LIQUID AND SAID GAS MEDIA TO CAUSE EVAPORATION OF THE MORE VOLATILE FRACTION FROM SAID LIQUID AND ENRICHMENT OF SAID CARRIER GAS IN VAPOR OF SAID MORE VOLATILE FRACTION; (2) HEATING THE MOST ADVANCED PORTIONS OF SAID EVAPORATION CHAMBER AND THE FLUID MEDIA THEREWITHIN TO THE HIGHEST TEMPERATURE WITHIN SAID INCREASING TEMPERATURE CONDITION EXCLUSIVELY WITH EXTERNALLY DERIVED HEAT ENERGY; (3) MOVING THE VAPOR ENRICHED GAS FROM THE EXIT OF SAID EVAPORATION CHAMBER THROUGH A CONDENNSATION CHAMBER COUNTERCURRENTLY WITH RESPECT TO THE FLOW IN THE EVAPORATION CHAMBER AND IN HEAT TRANSFER RELATIONSHIP WITH PORTIONS OF SAID EVAPORATION CHAMBER PRECEDING SAID MOST ADVANCED PORTIONS TO PROGRESSIVELY COOL SAID VAPOR ENRICHED CARRIER GAS AND CONDENSED VAPOR THEREFROM AND TO PROGRESSIVELY HEAT THE FLUID MEDIA MOVING WITHIN SAID PRECEDING PORTIONS OF SAID EVAPORATION CHAMBER; (4) SAID EXTERNALLY DERIVED HEAT ENERGGY IN SAID STEP (2) BEING PROVIDED ADDITIONALLY TO AND AT A TEM HIGHER THAN THE HEAT CONTAINED IN SAID VAPOR ENRICHED CARRIER GAS MOVED THROIUGH SAID CONDENSATION CHAMBER IN SAID STEP (3); (5) SAID HEATING OF SAID MOST ADVANCED PORTIONS OF SAID EVAPORATION CHAMBER IN SAID STEP 2 AND SAID HEATING OF PRECEDING PORTIONS THEREOF IN SAID STEP 3 PROVIDING AMD MAINTAINING SAID SUBSTANTIALLY PROGRESSIVELY INCREASING TEMPERATURE CONDITION WITHIN SAID EVAPORATION CHAMBER; (6) REMOVING SAID CARRIER GAS FROM SAID CONDENSATION CHAMBER.

Abstract:
1. PROCESS FOR THE PRODUCTION OF ALUNIMUM CHLORIDE WHICH COMPRISES REACTING CHLORINE AT A TEMPERATURE OF BETWEEN ABOUT 450*-800* C. WITH ALUMINA HAVING AN AVERAGE ALPHA ALUMINA BEING INTERMIXED WITH CARBON AND WEIGHT AND AN AVERAGE SURFACE AREA OF AT LEAST ABOUT10 M.2/G., SAID ALUMINA BEING INTERMIXED WITH CARBON AND COMPOSITELY HAVING AN AVERAGE HYDROGEN CONTENT OF LESS THAN ABOUT 0.5% BY WEIGHT AND AN AVERAGE CARBON CONTENT OF ABOUT 15-24% BY WEIGHT BASED ON THE TOTAL ALUMINA, CARBON AND HYDROGEN CONTENTS PRESENT, TO FORM A GASEOUS EFFLUENT CONTAINING ALUMINUM CHLORIDE AND CARBON OXIDES IN WHICH AT LEAST ABOUT 25% BY WEIGHT OF SUCH CARBON OXIDES IS CARBON DIOXIDE, AND RECOVERING THE ALUMINUM CHLORIDE FROM THE GASEOUS EFFLUENT.
Abstract:
Use of an alumina which has a total water of 3 to 20 wt.-percent and a surface area of at least 45 m2/g as cell feed improves the efficiency of operation of an electrolytic cell for reduction of alumina to aluminum.
Abstract:
An improved method of soldering aluminum members employs a solder consisting essentially of zinc, aluminum, and beryllium. The method uses dip or immersion soldering techniques, especially those involving ultrasonically energized baths.
Abstract:
A COATING COMPOSITION AND METHOD OF OBTAINING SAME BY MIXING AN ORGANIC SOLVENT WHICH CONTAINS AT LEAST 85% BY VOLUME PARAFFINIC HYDROCARBONS AND HAS A BOILING POINT OF AT LEAST ABOUT 3000*F. WITH A CROSS-LINKABLE RESIN LACQUER. AN OPAQUE WHITE COATING IS OBTAINED BY APPLYING THE COMPOSITION TO A SUBSTRATE AND CURING SAME THEREON.
Abstract:
Fluidized bed chamber having a fluidized bed receiving portion therewithin intermediate the fluidizing gas distribution inlet means at the lower end thereof and the gaseous effluent outlet means at the upper end thereof, said receiving portion having a peripherally confining side wall lining slightly inwardly and upwardly tapering, e.g., in steps, in a direction from said inlet means toward said outlet means to minimize the occurrence of unfluidized material adjacent said lining.
Abstract:
A method of manufacturing a package which comprises; coating substantially all of one surface of a metal web or foil or sheet thickness with a homogenous coating of a heat sealable thermoplastic material having a lubricant constituent; applying said coating material in uniform thickness to at least one first elongated zone of metal web; simultaneously applying the coating material in a uniform thickness greater that the coating thickness in the first elongated zone disposed adjacent opposed transverse sides of the first zone; applying the coating by means of a gravure roll; providing a coating thickness in the second zone of about 0.75 to 4.0 lb./ream and providing a coating thickness in the first zone of about 0.30 to 2.0 lb./ream; and forming a package employing said coated metal web as a body component by heat sealing at least a portion of said second zone to a portion of said metal web or to another package component. A coated container body comprising a metal web provided with such two level coating; a first elongated zone of uniform coating thickness spaced inwardly for opposed transverse edges of the metal web; a second elongated zone of uniform coating thickness positioned intermediate each transverse edge of the metal web and the first elongated zone; the first zone having a width substantially greater than the second zone; and said metal web having at least one said second zone heat sealed to another portion of said metal web or to a separate package component to form said container body.
Abstract:
A tubular bat body having an apertured end closure covering one end of the bat body. A cover element secured to the end closure. The cover element having a head disposed generally adjacent the outer surface of the end closure and a shank extending into the closure aperture and in contact with the aperture defining surface. An anchor section formed as an extension of the shank having shoulder means in locking engagement with the closure inner surface. The anchor section may have pilot means for facilitating insertion of the shank into the closure aperture. The cover element or indicator has means providing information regarding one or more bat properties. The shank may have a generally web-like configuration with substantially parallel opposed marginal edges and stiffener fins may be provided. The anchor section may be substantially triangular with the base of the triangle serving to provide locking shoulders and the other sides providing the pilot surfaces.
Abstract:
An easy opening device is provided which includes a score line in the container wall defining an opening flap adjacent an edge of the container wall and a tab having a nose end overlying the opening flap and affixed thereto and a handle end toward the opposite edge of the container wall with a line of weakening in the tab between its nose and handle ends for depressing the handle end of the tab to a non-obstructing position on the container wall, and which further includes an upwardly embossed hook in the container wall for engagement over an edge portion of the handle end of the tab to restrain it in a non-obstructing position on the container wall. A method of forming an embossed hook for engaging a tab is also provided.
