Title: Process to remove rare earths from spent nuclear fuel
Inventor: TAYLOR PETER
IPC: G21F9/06
Filed: 1996-05-14
Abstract: The present invention relates to a process for removing rare earth elements (RE) from spent nuclear fuel. The spent nuclear fuel is subjected to an oxidation step at a temperature of between about 200{ to about 800 {C and a heating step at a temperature of between about 1000 {C to about 1600 {C. The process results in the segregation of the spent fuel into a rare earth-rich fluorite-type phase and a rare earth-poor U 3 O 8 phase. The RE-rich fluorite type phase is separated from the RE-poor U 3 O 8 phase by conventional separation techniques such as sieving, air classification, sedimentation and the like.

Title: Automatic regulating valve apparatus
Inventor: YOKOTA HIROSHI
IPC: G05D9/04
Filed: 1997-10-02
Abstract: An automatic regulating valve apparatus, in which a main valve unit is driven interlockingly with a pilot valve unit. The main valve unit is provided in a main valve casing with a main valve disc and a main valve driving member the pressure receiving surface area of which is larger than that of the main valve disc which are incorporated therein in one body. The main valve disc is positioned on the upstream side of the main valve seat and forms a throttled flow passage between the main valve disc and main valve seat. The main valve driving member is fitted slidably in a cylindrical wall portion of the main valve casing and forms a main valve driving pressure chamber between the main valve driving member and the mentioned wall portion. The pilot valve unit comprises a pilot valve A and a pilot valve B which are operated interlockingly with each other, the pilot valve A and pilot valve B which are opened and closed in accordance with the change of the difference between the pressures before and after an orifice provided in the main valve, the liquid level on the downstream side of the main valve unit, and the pressure on the upstream side of the main valve unit communicate in series by a communication passage between the upstream and downstream sides of the main valve unit via the main valve driving pressure chamber formed between these valves. Owing to the interlocking operation of the pilot valve A and pilot valve B, the inner pressure of the main valve driving pressure chamber is changed, and a passing fluid is automatically controlled while controlling the degree of opening of the main valve disc, whereby the automatic regulating functions including the constant flow rate control function, emergency interruption function, liquid level control function and upstream side pressure control function are produced.

Title: Merging a sequence of delta files
Inventor: WILLIAMS DOMINIC CHRISTOPHER C
IPC: G06F17/30
Filed: 1999-08-11
Abstract: A method of and an apparatus for merging a sequence of delta files is described. The delta files together define a series of changes between a base file and an updated file, each delta file defining one or more changes in terms of one or more unique tokens each identifying original data or of one or more reused tokens identifying data reused from the immediately preceding delta file or the base file. The method comprises creating an initial merge structure from the base file and the first delta file in the sequence. A further merge structure is created from the initial merge structure and the next delta file in the sequence and adjusted by comparing tokens in the merge structures and replacing reused tokens in the further merge structure with corresponding tokens in the initial merge structure. The initial merge structure is then replaced with the further merge structure so that the further merge structure becomes the initial merge structure. The operations of creating a further merge structure and replacing the initial merge structure with a further merge structure are repeated for all delta files in sequence order. The thus created merge structure represents all changes between the base file and the updated file. The corresponding apparatus may comprise a suitably configured computer.

Title: Production of sintered compact of titanium-nickel alloy
Inventor: FURUKAWA AKIHISA
IPC: C22C19/03
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To produce a sintered compact of TiNi alloy, suitable for shape memory and superelastic material, by mixing Ti powder and Ni powder into specific composition ratio, alloying the resultant powder mixture, and then performing press compacting and sintering. SOLUTION: Ti powder and Ni powder are mixed to obtain a mixture having a composition ratio consisting of 49-51 atomic % and the balance essentially Ni. The resultant powder mixture is alloyed by a mechanical alloying method by using a ball mill in an inert or reducing atmosphere and then press- compacted and sintered, by which a sintered compact of TiNi alloy is produced. At this time, The Ti powder is prepared by an atomizing process and its average grain size is regulated to <=100μm, and the Ni powder is prepared by a carbonyl process and its average grain size is regulated to a value smaller than that of the Ti powder. By this method, a TiNi single phase can be obtained, and the sintered compact of TiNi alloy, having a relative density exceeding about 90%, can be obtained.
