Inventor: COX DONALD MARTIN
IPC: B01D59/34

Abstract: A method of separating isotopes of an element, for example uranium, comprises providing molecules of a compound of the element which have isotopically shifted infrared absorption spectra. For uranium such molecules can be a mixture of  235 UO 2 - and  238 UO 2 -containing molecules of UO 2 (A 1 A 2 ).L, where A, and A 2  are monovalent anions, such as CF 3 COCHCOCF 3 , and L is neutral ligand, such as trimethylphosphate. The molecules are irradiated at a first infrared absorption frequency to isotopically selectively dissociate them and provide molecular fragments containing the element. The fragments are then irradiated at a second infrared absorption frequency shifted, preferably to the blue of the first frequency, by less than about 100 cm-'. Preferably initiation of the second irradiation occurs between 0.1 and 10 microseconds after initiation of the first irradiation.

Abstract: A subscriber line interface circuit is described wherein current supplied to a telephone subscriber line from a shared voltage source such as a DC/DC converter is regulated thereby permitting a regulated line current to be supplied to a plurality of line circuits from a single shared voltage source. In accordance with the present invention, both the dc line feed and the ac transmission requirements of a subscriber line interface circuit for a telephone exchange are implemented in a single circuit incorporating ac and dc impedance synthesis techniques. A significant reduction in the heretofore required expensive and bulky discrete components of the subscriber line interface circuit is achieved.

Abstract: A method is disclosed for producing a dimensionally stable UO 2  fuel pellet of large grain size and relatively large pore size. A dopant containing an element selected from aluminum, calcium, magnesium, titanium, zirconium, vanadium, niobium or mixtures thereof is added to a highly sinterable UO 2  powder, which is a UO 2  powder that is sinterable to at least 97% theoretical density at 1600°C in one hour, and the UO 2  powder can then be formed into fuel pellets. Alternatively, the dopant can be added at a step in the process of producing ammonium diuranate. The ammo. nium diuranate is collected with from 0.05 to 1.7 mole%, based on UO 2 , of a compound containing said element. That mixture is then calcined to produce UO 2  and the UO 2  is formed into a fuel pellet. The addition of the dopant can also be made at the hydrolysis stage in the manufacture of U0 2  by a dry conversion process.
