Abstract: In a total recycle urea-producing system, the improvement is disclosed which consists in providing in the reactor two adjoining but separated reaction spaces, called first and second reaction zones, the surface which separates the two zones being a heat-exchanging surface. Fresh ammonia and carbon dioxide are fed with a portion of excess recycled ammonia to the first reaction zone, wherein the reaction is exothermic in character, whereas the condensates from the carbamate decomposition and the remaining portion of the excess recycled ammonia are fed to the second reaction zone, wherein the reactions are of an endothermic nature. By so doing, a better thermal balance in the reactor is obtained, concurrently with improved yields.

Abstract: Steam curable agglomerates of particulate material are cured by passing steam at elevated temperature and pressure through a bed of such agglomerates in an autoclave. The flow direction of the steam through the bed is periodically reversed, at least during the temperature raising period of the autoclaving process, to reduce the autoclaving time and produce cured agglomerates of substantially uniform quality.

Abstract: A pressure reactor which avoids leakage and prevents sample loss upon depressurization. Leakage is avoided by providing a reaction vessel with a screw-threaded closure member. Loss of sample is prevented by the provision of a vapor trap which collects any liquid or vapor which may include dissolved sample, from escaping upon disassembly i.e. de-pressurization of the reactor. A novel solvent system for use in conjunction with the reactor is also disclosed.

Abstract: A method for reclaiming rubber in which the scraps to be reclaimed are treated in an autoclave at a temperature which is always below the temperature at which the scraps had been cured, with continuous agitation and under the pressure of a fluid (such as air) fed to the autoclave at the ambient air temperature. The processing time is a function of the other parameters and can easily be determined experimentally depending upon the nature of the material to be reclaimed and the plasticity to be obtained.

Abstract: A static discharger includes a vertical casing connected to a pressurized pulping digester for receiving a stream of fibrous material and having a valve isolated scrap collector positioned on its lower end. A discharge neck on which a blow valve is mounted extends from the casing above the scrap collector and is covered with a grid plate having self-cleaning openings. A pipe mounted tangentially on the casing introduces flooding liquid thereto while a similar pipe may be located on the scrap collector. A sealed casing cleanout opening may be provided. No moving parts are involved since discharger agitations result from the flooding media. Heavy foreign body impurities in the stream sink to the scrap collector where they are removed without process interruption. Buoyant objects remain suspended in the liquid. Blow valve plugging is eliminated. For higher fiber consistency, a grid plate wiping agitator may be advantageously installed in the casing.

Abstract: A high temperature reactor-generator apparatus for the high temperature conversion of a reactant stream of which reforming hydrocarbons into gaseous products, dissociating ammonia, partial oxidation of hydrocarbon feeds, high temperature catalytic reforming and the like are examples. The apparatus comprises a pressure vessel, a conduit within the vessel having upper and lower ends and sides spaced from the pressure vessel walls, a partition intermediate the ends of the conduit member and spanning the space between the vessel and the conduit member to divide the interior of the vessel into an upper reactor chamber and lower reactor chamber, means for introducing a fluid reactant into the lower chamber for flow therethrough and upwardly through the conduit into the upper reactor chamber, a heat supply for heating the lower reactor chamber, a reaction products outlet from the upper chamber and means for supplying heat to the lower reactor chamber for causing the reaction. The means for flowing a fluid in heat exchange relationship with the upper reactor chamber may take any form desired such as a fluid coil in the upper chamber or an injector for injecting the fluid directly into contact with the fluids in the upper chamber.

Abstract: An autoclave body is formed with a pressure chamber which has a closable ning; to permit rapid replacement of a rupturing membrane, the body is formed with a slot, channel, or notch, in which a strip of membrane material can be inserted, to be secured against the opening of the chamber by a quick-release movable pressure head, so that, upon rupturing of the membrane facing the pressure head, a new element of membrane material can be quickly placed over the opening of the chamber. The movable pressure head is hollow, with a cylinder opening facing the pressure head opposite the membrane side which closes the opening, and a piston is located in the hollow of the pressure head, to permit application of a vacuum to the side of the membrane not facing the opening of the pressure fluid chamber. The measuring cells are located diametrically opposite from each other, at an inclination with respect to the axis of the cell, so that the axes of the measuring elements face upwardly, to avoid entrapment of air bubbles at the faces thereof. At least a portion of the entire cell is formed with an internal chamber through which a thermostatically controlled temperature control fluid is circulated to maintain the cell at an event temperature.
