Agglomerated material is passed through a beater mill and subjected simultaneously to the beating action of a plurality of blades and a vigorous stream of air as the agglomerated material impacts the peripheral screen of the beater mill.

Abstract: Method and apparatus for the control of velocity and pressure of hot gases flowing through a conduit wherein generally spherically shaped objects of refractory material are disposed within such conduit during the operation thereof to provide a constriction of the cross-sectional area of the conduit through which the gases are flowing. A particular embodiment of apparatus employed in the present invention comprises a pair of generally spherically shaped refractory objects secured together by means of a length of steel cable.

Abstract: Catalyst/oil mixing in a catalytic cracking unit can be effected at approximately right angles by introducing the liquid oil axially into the mouth of the riser and bringing the catalyst radially inwardly into the mouth of the riser from substantially the entire circumference thereof.

Abstract: In an extrusion process, desired product quality parameters are maintained very accurately by manipulating the rotational speed of the screw associated with the extrusion process so as to maintain a desired ratio of feed rate to drag flow in the extrusion process and by manipulating the feed rate of the material to the extrusion process so as to maintain a desired energy input per unit of the material being processed.

Abstract: A composition that can be rotationally molded with a minimum formation of voids comprises a polymer and a metal stearate.

Abstract: An alkylated diphenyloxide composition is prepared by reacting diphenyloxide with isobutylene in the presence of sulfuric acid and applications for the composition.

Abstract: A method of rotationally molding hollow articles from cross-linkable polymeric material wherein the mold and molding material are simultaneously revolved about two nonparallel axes while being heated to fuse and cross-link polymeric material. When the polymeric material is partially cross-linked the mold containing the hollow article is opened at at least one location to admit heated air circulated therethrough to facilitate cross-linking of the inner portion of the molded tubular article and produce a smooth inner surface therein. Also disclosed is apparatus for performing the molding method of the invention.

Abstract: A method of forming a heat resistant gas transfer line. The line includes a metal outer shell, a tubular inner liner formed of a plurality of prefired refractory rings joined together by shiplap joints having expansion gaps, and an intermediate liner including bubble alumina concrete filling the annular space between the inner liner and the outer shell.

Abstract: A variable amplitude/phase color seismic display is provided which increases the ease with which interpreters can locate peaks, troughs and other information of interest.

Abstract: A method for condensing a gas in a liquid medium to prevent the formation of gas hammer, comprising impinging a gas against a plate at such a velocity so as to cause the gas to fan out in a thin sheet before condensing in the liquid medium.

Abstract: A composition is provided which, when applied to a metal surface, forms a corrosion-inhibiting film thereon. The composition comprises an epoxy resin, an effective amount of a curing agent for the epoxy resin, an onium salt, and a hydrocarbon diluent. The composition optionally further contains an alcohol. The onium salt can be, for example, a quaternary ammonium salt. The composition is applied by contacting the metal surface with the composition. The composition is useful in the treatment of downhole metal surfaces in oil and gas wells to inhibit corrosion of the metal.

Abstract: For parallel heat exchangers, one using a more preferred heat exchange medium as a heat exchange source and another using a less preferred heat exchange medium, maximum use of the more preferred heat exchange medium is used prior to use of the less preferred heat exchange medium in achieving a desired total heat exchange through the parallel heat exchange system. In employing such a heat exchange system in a cracking process it is combined with individual control of flows of feed fluid and diluent fluid to a plurality of individual cracking tubes in a cracking furnace to maintain a desired mass flow of feed fluid and ratio of mass diluent fluid to steam fluid to each such cracking tube.

Abstract: An integrated control system for a vinyl acetate process. A desired production rate of vinyl acetate is achieved by maintaining a desired reactor temperature. At the same time, the concentration of oxygen in the vinyl acetate reactor and condenser are maximized and the reactor pressure is maximized, all in a safe manner, so as to increase the selectivity of the process to the production of vinyl acetate. Also, the overall process is controlled so as to improve the efficiency of energy and materials usage.

Abstract: A process for the destructive distillation of hydrocarbonaceous solids in a retort, wherein a viscous bridging zone comprising viscous liquids in intimate contact with solids, which tends to impede the flow of vaporized hydrocarbons and the flow of solid particles, is agitated by reciprocating mechanical means actuated by a rotatable crankshaft.

Abstract: The catalytic hydrodesulfurization and/or hydrodenitrogenation of an organic sulfur compound and/or an organic nitrogen compound is carried out in the presence of a hydrogel derived catalyst comprising zinc titanate and alumina promoted with cobalt and molybdenum.

Abstract: In a system in which a continuous, periodically repeated, pulse duration type signal is utilized to transmit information to a computer, the pulse duration type signal is converted into a series of clock pulses. The clock pulses are then counted for a period of time equal to the repetition period of the pulse duration type signal. This count is then latched and transferred to the computer to thereby accomplish the transfer of information to a computer by means of a continuous, periodically repeated, pulse duration type signal.

Abstract: In a system wherein a peripheral computer is utilized to lighten the load on a central computer or to perform a special function which cannot be performed by the central computer, method and apparatus is provided whereby the central computer can be utilized to program the peripheral computer. A volatile memory is programmed by the central computer and then the volatile memory is switched to the peripheral computer to allow the peripheral computer to run the program set up in the volatile memory to determine if the program is operational. Once the program has been determined to be operational, the program is transferred to a nonvolatile memory which is associated with the peripheral computer system and the program is then available for use in the peripheral computer system.

Abstract: Polymers containing repeat units based on substituted or unsubstituted pentadienyl chloride monomers are disclosed. The polymers are fast curing and some of the polymers are self-curing.
