Abstract: ABSTRACT         Coal particles are heated and further particulized at a preheat stage employing a preheat gas.  Some of the finer coal particles are puffed up by the preheating step.  Most of the preheated coal particles are separated from the preheat gas, but some of the finer coal particles remain with the preheat gas.  The coal particles separated from the preheat gas are oiled and eventually transported by a carrier gas through a pipeline into a coke oven.  The preheat gas and the finer coal particles remaining therewith are separated from each other utilizing a wet scrubber at which the finer coal particles undergo flocculation.  Oil vapor vented from the coal particles headed for the coke oven is directed to the wet scrubber to aid in the flocculating step.  The flocculated coal particles are separated from the scrubber liquid in a flotation cell.  The overflow from the flotation cell is filtered, and the filter cake comprising coal particles is employed as a fuel.  At least some of the underflow from the flotation cell is recycled as scrubber liquid to the wet scrubber.  The liquid from the filtering step is employed to precipitate, in a charging main, fine coal particles discharged with carrier gas into the charging main during charging of the coke oven.

Abstract: PROCESS AND APPARATUS FOR PREPARATION OF SULFUR         FOR STORAGE AND TRANSPORTATION                    Abstract of the Disclosure A process and apparatus for producing solid, irregular shaped sulfur  nuggets  from molten sulfur.  The method includes the steps of:  flowing the molten sulfur in a feed system where the temperature of the sulfur is controlled within a desired range; flowing the sulfur to a processing unit where the sulfur is dis-charged in ribbon-like streams into a body of water which solidi-fies the sulfur into irregular solid  nuggets,  depositing the sulfur on a conveyor in the processing unit; and moving the solid-ified sulfur  nuggets  from the processing unit on the conveyor to storage or transport facilities.  One form of feed system has a receiving tank system including several interconnected tanks pro-vided with steam coils in the sides and bottoms for maintaining the molten sulfur at a temperature above the level at which it solidifies.  Another form of feed system is a serpentine-shaped conduit through which liquid sulfur flows from a heated storage container such as a tank car to the processing unit.  The proces-sing unit which forms the liquid sulfur into the irregular sulfur nuggets   for improved handling and storage includes a water res-ervoir, a discharge or distributor head for flowing the liquid sulfur into the water, and a conveyor for receiving and removing the sulfur  nuggets  from the water.  A number of different forms of distributor heads are disclosed, each of which discharges one or more ribbon-like streams of liquid sulfur into the water reser-voir.  In one form of system the discharge head introduces the ribbon-like streams of sulfur into the reservoir under the water surface.  In another form of the system, the discharge head drops the liquid sulfur through an air space above the water into the water.  In the method carried out with each form of the disclosed apparatus, the ribbon-like streams of sulfur fragment and solidify within the water reservoir forming sulfur  nuggets  of irregular shape and size which may be efficiently handled and stored.

Abstract: METHOD OF SOFTENING NONWOVEN FABRICS     ABSTRACT OF THE DISCLOSURE         A bonded web of nonwoven fibers is stretched beyond its elastic limit in one direction sufficiently to permanently elongate those filaments or filament portions of the web extending generally in the direction of the applied tension.          This results in a narrowing  or necking down of the web in the cross direction and consequent shortening or lateral buckling of those filaments or filament portions extending generally transverse to the direction of applied tension.  This imparts increased softness, flexibility and resilient stretchability to the fabric, in that transverse direction.  The elongated filaments are then compacted longitudinally while the web is retained in its narrowed condition to impart increased softness, flexibility and resilient stretchability in the longitudinal direction.

Title: Apparatus for indirect evaporative cooling of upflowing fluid by contact with downflowing water from overlying evaporative cooling section

Granted: 1978-09-19
Abstract: ABSTRACT OF THE DISCLOSURE         A high efficiency, induced draft, combination counter-flow-crossflow fluid cooling apparatus and method is provided which gives unexpectedly enhanced cooling of hot fluid by causing the fluid to pass upwardly through a series of serpentine heat exchange conduits in primarily countercurrent, indirect sensible heat exchange relationship with external cooling water gravita-ting from an overlying evaporative water cooling section.  Cross-flowing air currents are pulled through the apparatus to evapora-tively cool the water not only in the upper cooling section but also in the sensible heat exchange area as well.  Countercurrent flow of coolant water and fluid to be collected ensures that the coldest water and coldest fluid are in thermal interchange during the final stages of fluid cooling at the upper ends of the heat exchange conduits, so that the fluid temperature can approach that of the cold water as opposed to approaching the temperature of heated water found adjacent the lower ends of the conduits, which is conventional in cocurrent flow units of this type.  The fluid conduit system is preferably arranged for causing increased fluid residence time, and thereby greatest temperature difference and longer heat exchange between the fluid and coolant water adjacent the air inlet of the apparatus where air and coolant water temperatures are lowest relative to the fluid to be cooled, so that an ideal countercurrent flow relationship is obtained and maximum heat transfer is assured.  An underlying water collection basin is also employed in the apparatus which is constructed to permit collection of cooling water to a level above that of the lowermost portions of the hot fluid conduits, in order to allow the hot fluid traveling through the conduits to beat the col-lected water to prevent freezing thereof during wintertime oper-ations when the internal water pump is shut down causing the stoppage of all evaporative cooling and hence a raising of the lower water basin level.
