Abstract: The process of the present invention which produces the flexible integration for the production of ammonia and urea uses adiabatic reforming of the carbonaceous feedstock such as natural gas. With adiabatic reforming of natural gas, a surplus of carbon dioxide is produced. With adiabatic reforming, substantially pure oxygen and nitrogen may be used which does not involve inert gases such as argon in the system. More importantly, adibatic reforming allows operation at much higher pressure than standard primary reforming, namely, between 700 and 3000 psig. When these pressures are used, the process includes a recycle of the methane and hydrogen from the ammonia synthesis loop to the adiabatic reformer.The process of the present invention uniquely removes the carbon dioxide which is produced by the reforming of the carbonaceous feedstock and treatment by the watergas shift reaction in two independent stages.

Abstract: A method and apparatus for cleaning the interior of storage tanks of the type used for storing large volumes of liquids, such as crude oil, wherein hydrocarbon sludge accumulates with the passage of time, such apparatus comprising a hollow housing, liquid agitation means including a plurality of nozzled outlet jets laterally rotatably mounted on the housing in fluid communication with the hollow interior thereof, connecting means comprising an independently rotatable tubular casing rotatably mounted on the housing in fluid communication with the interior thereof, the tubular casing having a kelly mounted therein and being operatively connected with the nozzled outlet jets, and multi-joint support pipe means rotatably joined to the connecting means in fluid communication with the interior of the tubular casing.

Abstract: Method and apparatus for measuring apparent earth resistivity, by determining potential drop produced by electric current injected into the ground. Periodic, or very low frequency polarity reversal of direct current is used to eliminate induced voltage errors that might otherwise occur with higher frequency polarity reversal or alternating current. Synchronizing pulses are used to gather and separately store information from each half cycle. A calibrated readout is obtained in which values of the voltages in the two half-cycles are algebraically subtracted and divided by two to measure the potential drop, with automatic compensation for effects of earth currents.

Abstract: In one example embodiment, a female urinal is disclosed that includes a generally rectangular open container having a flat bottom portion with generally upright continuous side and end walls. One transverse end includes an upwardly and outwardly slanting wall cooperating with the adjacent side walls to provide a drainage ramp into the interior of the container. The other transverse end carries an indented shoulder disposed in the bottom and adjacent the end wall for permitting easy hand grasping of the urinal for transporting after use.

Abstract: In an open-atmosphere flame spray gun system for spraying molten particulate material and a method of spray application, an improved eductor mechanism and flame spray gun permits a greater quantity of particulate material to be delivered to the article to be coated. The particulate material entrained in a stream of pressurized conveying air, a stream of pressurized burn/propelling air and a stream of fuel gas are delivered through a plurality of passageways extending through the gun body to a combustion chamber for mixing and ignition. The streams are delivered in concentric annular relationship to the combustion chamber, with the stream of particulate material and conveying air and concentric annular stream of burn/propelling air being directed into the combustion chamber in an outwardly expanding conically-shaped axial cross-section for enhancing the diameter and length of the flame produced by the gun and permitting an increased quantity of particulate material to be melted and delivered for coating.
