Title: Process for obtaining deuterium from hydrogen containing compoun ds and the production of heavy water therefrom
IPC: C01B4/00
Filed: 1971-10-07
Abstract: 1364714 Deuterium enriched hydrogen GULF RESEARCH & DEVELOPMENT CO 7 Oct 1971 [28 Oct 1970] 46655/71 Heading C1A Deuterium is concentrated in hydrogen by contacting vapour of a deuterium containing hydrocarbon with gaseous hydrogen containing less than the natural abundance of deuterium, the contacting taking place in the presence of a hydrogenation/dehydrogenation catalyst at an elevated temperature and recovering the deuterium enriched hydrogen from the hydrocarbon material of reduced deuterium content. The feed gas, e.g. methane, is introduced into the catalytic bed 12 via line 10, together with a deuterium poor hydrogen stream via a line 14 using a temperature in the range from 204 to 982 C. The hydrogen is separated from the feed gas in separator 18 which feed gas is then eliminated by line 20. The deuterium enriched hydrogen stream is removed by line 22 and passed to fractionator 24 where the stream is separated, e.g. cryogenically, to give a further D2 enriched H2 stream and a deuterium poor stream which is recycled via line 14, the enriched stream being passed into contact with an equilibration catalyst in zone 28, the equilibrium mixture being further fractionated to give a deuterium enriched stream which is recycled to the first zone by line 34 and a pure deuterium stream which is withdrawn via line 36 and may be burnt with substantially pure oxygen to give reactor grade D2O. In a further embodiment, Fig. 2 (not shown), the D2 poor H2 stream from the fractionator is brought into contact with the D2-poor hydrocarbon from the separator, and the resulting hydrogen stream is recycled to the first contacting stage and the now depleted source material recycled for storage or use. The preferred source material is natural gas, e.g. hydrocarbon containing less than 6 C atoms, preferably methane,. The. source material is preferably purified from unwanted, possibly interfering, contaminants before being contacted with the H2 stream. The first transfer stage may be at a subatmospheric or a superatmospheric pressure.

[Also in Divisions G1 and H1] In a method of sorting articles (e.g. ore which emits radiation or is preferentially coated in accordance with Specification 1,078,430 to render it fluorescent or phosphorescent) individual articles are ejected by continuous fluid streams deflected in response to the detection of an article having a desired characteristic. As shown ore preferentially coated in accordance with the above referred to specification leaves a conveyor 1 and falls past a source 2 which emits radiation via a filter which passes wave-lengths less than 3600 angstroms, past a row of detector positions 3 from where radiation is conveyed by light fibres to photomultipliers and past the ends of a row of tubes 10. The tubes which have flexible portions 43 normally rest in a lower position in which water, which flows continuously through the tubes from a header 40 is deflected away by a plate 11. Each tube can be raised to deflect a piece of ore from its normal path where it would land on a conveyor 8 to a second path where it would land on a conveyor 7 by a corresponding magnetic assembly (see division H1) in response to a pulse from a corresponding photomultiplier. The period for which each tube is raised is proportional to the length of the pulse received from the corresponding photomultiplier.

Abstract: 1319882 Polishing MONSANTO CO 20 Oct 1971 [21 Oct 1970] 48805/71 Heading B3D A process for polishing a wafer 44, such as a semi-conductor, comprises pressing the wafer between a mounting pad 40 and a polishing surface 17, the coefficient of static friction between the wafer and mounting pad being greater than the coefficient of static and dynamic friction between the wafer and the polishing surface, and producing relative motion between the polishing surface and the wafer, the wafer remaining fixed with respect to the mounting pad as a result of the different coefficients of friction. In apparatus for carrying out the method, the polishing surface is of poromeric material such as fibre reinforced polyurethane foam mounted with its substrate surface exposed on a turn-table 14 spaced from an outer wall 12 whereby a space 16 therebetween permits a polishing agent, such as silica sol supplied in droplets 50 to flow freely away from the table. The mounting pad 42 is also of poromeric material and is secured to a disc 40 with its front surface, i.e. its high friction surface which is a coating of unreinforced microporous polyurethane exposed. The disc is mounted by a spherical bearing 36 on a pin 32 extending from an arm 22 carried by a shaft 24 controlled for vertical and horizontal movement. The wafer 44 is initially held by surface tension on the pad 42 and is then pressed against the polishing surface 17, the higher friction retaining the wafer on the pad as it is rotated by the rotation of the turn-table. In another embodiment, the polishing surface has an outer annular area 18, Fig. 3, of low friction poromeric substrate material and an inner area of higher friction material such as polyester reinforced polyurethane with its front surface exposed. In the first embodiment, after polishing, the wafer is removed from the pad by a suction tool, whereas, in the second embodiment, at the end of polishing by the surface 20, a rotational impulse of the turn-table releases the wafer from the pad. More than one wafer may be polished at the same time by having a plurality of mounting pads carried by pins on arms extending from the arm 22. The wafer may be a refractory oxide or magnetic bubble material.
