Title: Isotope separation process
IPC: B01D59/34
Filed: 1979-12-03
Abstract: A method for the separation of isotopes is disclosed including providing a vapor of a compound of the element whose isotopes are to be separated, the compound having an isotopically shifted but overlapping infrared absorption spectrum associated with the isotopes of that element within a predetermined temperature range; irradiating the vapor with a predetermined fluence of infrared radiation which is preferentially absorbed by an molecular vibration of the molecules of the compound containing a predetermined isotope of the element, thereby providing excited molecules enriched in the predetermined isotope; and maintaining the vapor at a temperature within the predetermined temperature range which, at thermal equilibrium, provides sufficient molecules requiring more than single photon to promote dissociation so that upon dissociation the isotopic selectivity is at least ten percent above the maximum selectivity which can be achieved with an ensemble of molecules each of which can dissociate by absorbing a single photon. The thus excited molecules are thereby rendered separable. In a preferred embodiment, the isotopes of uranium are separated utilizing a CO2 laser, and a uranyl compound having the formula UO2A2.L, where A is a monovalent anion and L is a neutral ligand having a basicity towards the uranyl ion stronger than that of tetrahydrofuran. Anion A is preferably 1,1,1,5,5,5-hexafluoracetylacetonate and L is preferably trimethylphosphate.

Filed: 1981-12-09
Abstract: A web splicer (10) includes a web guide duct (8) through which one or two webs are forwarded by an airstream to a splicing zone (10). The webs are presented to the duct inlet by pivoted web guides (31, 32). Either one of the webs can be placed in the duct (8) and splicing zone (10) whilst the other web is continuously fed during winding. In use, the leading end of a web from reel (15, 15) is initially engaged and passed through pivoted guide (31, 32) by air jets carried at the guide inlet. During initial threading up, following web breakage or during splicing the web in the duct can be forwarded by the air jets through the guides duct (31, 32 and 8) and, subsequently, drawn through the system by rollers (75, 76). If one web breaks and its supply reel is nearly exhausted, splicing to the other web is effected. During splicing, initially, the leading end of a new web is forwarded and then stopped to lay in guides (31 or 32, 8 and 63 or 64). Then, a buffer stock of the running web is formed in store (80), knife (57) severs the two webs in duct (8), the trailing end of the previously running web is rewound onto its reel (15 or 15), a splicing patch is applied by descending block (56), the leading end of the previously stationary web is sucked away via duct (63 or 64) and winding recommences. The web forwarding and splicing sequences are controlled by sensors (52, 53, 63-66 and 74) and pivotal guides (31,32) monitoring the radius of the web reels (15, 15). The reels (15, 15) are automatically loaded at the splicer by pusher (27) sliding the reels one by one onto the reciprocatable drum (15) which comprises reel-engaging dogs (28), see Figure 2 not shown and UK Application 8135052. <IMAGE>
