Filed: 1972-05-18
Abstract: 1370064 Ammonia; hydrogen FLUOR CORP 18 May 1972 [27 May 1971] 23319/72 Heading C1A Hydrogen obtained from shift effluent is indirectly heat-exchanged with a refrigerant solvent mixture circulating in a closed absorption cycle, absorbing carbon dioxide from the effluent using an organic solvent, reacting the hydrogen with nitrogen in an ammonia synthesis zone, and indirectly heat exchanging the synthesis zone gases in said refrigerating cycle to separate ammonia therefrom. The preferred physical solvent is propylene carbonate. The shift effluent may be employed at a pressure above about 250 p.s.i.g. and the ammonia product may be cooled to a temperature between - 15‹ and 100‹ F. The refrigerating cycle may comprise an ammonia water system including an absorption zone, a fractionation zone to separate ammonia from water and an expansion zone to evaporate ammonia to produce cold. The heat for the fractionation zone is obtained by heat exchange from the shift effluent. Other acid gases, e.g. H2S may be removed by the organic solvent. The initial shift effluent may be obtained by reaction of steam and a hydrocarbon, the carbon monoxide product being oxidized to carbon dioxide by addition of air.

Abstract: 1506996 Throttle valve control systems SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 8 June 1976 [26 June 1975] 23699/76 Heading F1H [Also in Division G3]  A carburetter for an I.C. engine has an intake pipe 2, an operator-controlled throttle valve 5 in the intake pipe and stop means for preventing the throttle valve from closing beyond a predetermined minimum opening position in which there is an airflow-path between the throttle valve and the intake pipe wall, an idling circuit 7, 8, 9 which opens into the intake pipe at ports 10 and 13 and also has a throttle valve adjustment means which, if the load on the engine is increased, opens the throttle valve by the amount necessary to maintain the desired idling speed, the adjustment means including a first pneumatic element 21 having movable wall means, means 25, 26, 27, 15 connecting the element to the intake pipe so that it is subject to the vacuum in the intake pipe, a second pneumatic element 36 having a diaphragm 37 connected to throttle valve 5 so as to drive it in the opening direction only and valve means 35 carried by diaphragm 37 and arranged to bc actuated by the movable wall of the first pneumatic element so that when the intake pipe pressure increases the diaphragm 37 moves in a direction to open the throttle valve. Pneumatic element 31 is an aneroid capsule, enclosed by container 23 and movable bodily by adjustment screw 28. When the engine is idling with no external load a pulse rod 30 mounted on the capsule engages the stem 35b of valve 35 and holds it away from diaphragm 37 so that orifices 45 and 46 are open. Atmospheric air from vents 52 and 53 passes through the orifices 45, 46 so that atmospheric pressure exists in chamber 47 and spring 55 moves diaphragm 37 until it abuts casing 54. If the engine slows down, due to the application of an external load, the pressure downstream of throttle valve 5 increases and this increased pressure is communicated to container 23, capsule 21 shortens and valve 35 closes. Pressure in chamber 47 then falls slowly as air is drawn through restriction 48 and diaphragm 37 moves towards capsule 21 and through lever 58, which carries a peg 59, opens throttle valve 5 to increase the engine speed to the original idling speed.
