Patent GB-1449091-A (GB)
Title: Process for partially oxidising organic compounds
IPC: B01J8/06
Filed: 1974-04-30
Abstract: A process for carrying out the partial oxidation of ethylene with oxygen to ethylene oxide in the vapour phase is described. In the process, the mixture containing ethylene and oxygen or oxygen-containing gas is fed to a heating zone packed with inert materials and subjected therein to heat exchange, the heated mixture then passes into a reaction zone packed with catalyst, where the oxidation of the organic compound takes place, next to the heating zone, and finally the reaction products obtained are cooled in a third zone which is or is not contiguous with the preceding zone, with or without inert packing, the heat removed in the cooling zone being used in the heating zone. The apparatus for carrying out such reactions comprises a tube-bundle and shell reactor divided on the shell side by two partitions into three zones. <IMAGE>

Title: Improvements in or relating to the removal of carbonaceous materials from sulphuric acid
IPC: C01B17/92
Filed: 1949-07-19
Abstract: Carbonaceous material is removed from sulphuric acid used for treatment of hydrocarbons by continuously countercurrently contacting the spent acid in an oxidising zone with air and nitric acid or any oxide of nitrogen other than N2O, the air being employed in sufficient quantity to provide free oxygen in the gaseous effluent, and passing the effluent comprising free oxygen, at least one oxide of nitrogen and water vapour to a cooling zone where nitric acid is formed, separating the nitric acid from the residual effluent and employing the nitric acid or nitrogen oxides obtained therefrom for the treatment of further spent acid, which has been concentrated to at least 70 per cent by weight, is passed into the top of a column maintained at 100-230 DEG C.  The acid from the base of the column may be passed continuously through a second stripping column against a current of air for removal of dissolved nitric acid and nitrogen oxides and the resultant gas mixture is passed to the first column. The condensation of the nitric acid may be carried out in the presence of sulphuric acid, which may be obtained from the base of the stripping column, and the resulting mixed acid contacted with the spent acid or passed to the top of the stripping column.

Title: Nuclear reactor fuel elements and their manufacture
IPC: G21C3/17
Filed: 1974-05-01
Abstract: 1465630 Fuel elements SAES GETTERS SpA 1 May 1974 [2 May 1973] 19120/74 Heading G6C A fuel element contains a non-evaporable getter material which, as the temperature of the fuel element is increased, starts to sorb active gases at a temperature lower than that at which the fuel element walls start to do so, and at a rate such as to prevent the said walls sorbing any appreciable amount of said gases, the said getter material having a sorptive capacity of at least 5 c.c.-torr./g. of CO at 20 C. By "non- evaporable getter material" is meant one which acts as a getter below its vaporization temperature. The fuel element (Fig. 1, not shown), comprises a hermetically sealed metallic container having walls forming a fuel-containing chamber and a plenum chamber. The getter device is placed within the plenum chamber, being separated from the end closure member by a helical spring and from the fuel by a ZrO 2  insulating pellet. Suitable getter materials are those described in Specification 1,463,538). The getter material may be housed in a container of e.g. molybdenum or graphite (Fig. 2, not shown), or be surrounded by one or more metal support rings (Fig. 5, not shown). In a further embodiment, shown in Fig. 3, a getter device 30 comprises an activated non-evaporable getter material 31 held within a metal container 32 by springs 33, 33<SP>1</SP>. One end of the container 32 is sealed by a thin metal foil 36 welded at 53 and having score lines defining an area of structural weakness which can be preferentially ruptured. The container interior 37 is either evacuated or filled with an inert gas, e.g. He at slightly above atmospheric pressure via a metal pumping stem 38 which can be pinched-off. During its manufacture, the fuel element is filled with He to 20 atmospheres pressure whereupon the foil 36 is ruptured and the getter material 31 exposed to the gases in the plenum chamber. In a still further embodiment, shown in Fig. 4, getter material 41 is held within a glass container 42 by springs 43, 43<SP>1</SP>. End 44 of container 42 is sealed by normal glass blowing techniques while the other end is a dome 45 of prestressed glass. The glass container 42 is placed within a metal holder 46 terminating at the end adjacent dome 45 in a wire mesh 47. The filling with He in this case causes the dome 45 to break into a large number of small pieces thus ensuring complete contact of the getter material 41 with the plenum chamber atmosphere.
