Title: Method of preparing primary refractory metal
Inventor: SHEKHTER LEONID NATAN
IPC: C22B34/00
Filed: 2006-03-15
Granted: 2014-11-04
Abstract: A method of preparing primary refractory metais (e.g., primary tantalum metal) by contacting a particulate refractory metal oxide (e.g., tantalum pentoxide) with a heated gas (e.g., a plasma), is described. The heated gas comprises hydrogen gas. The temperature range of the heated gas and the mass ratio of hydrogen gas to refractory metal oxide are each selected such that: (i) the heated gas comprises atomic hydrogen; (ii) the refractory metal oxide feed material is substantially thermodynamically stabilized (i.e., the concurrent formation of suboxides that are not reduced by atomic hydrogen is minimized);  and (iii) the refractory metal oxide is reduced by contact with the heated gas, thereby forming primary refractory metal (e.g., primary tantalum metal and/or primary niobium metal).

Abstract: Recombinant truncated human furin was expressed in CHO cells and concentrated approximately 50 -fold by ultrafiltration and diafiltration. The concentrate was purified by column chromatography on Capto-MMC~ resulting in a 30-50 fold purification factor and a yield of at least 60%. The at least 20% pure preparation obtained after Capto-MMC~ chromatography had already a purification degree allowing on-column maturation of pro-VWF. Then an additional Arginine Sepharose chromatography purification was carried out. This two column process for purification of truncated human furin resulted in an almost pure furin preparation with a specific activity of approximately 290,000 U furin/mg protein and a yield of about 50%.

Abstract: A system and method configured for applying Montgomery style reduction directly to negative quantities as well as positive values, producing the new form which does not require conditional operations to move values into the positive range. The low-order components of the resulting product, or partially completed product, can be reduced either by the addition of multiples of the modulus, as is usual in the standard Montgomery multiplication which accepts positive values, or by subtracting multiples of the modulus, which of course depends on the actual computation. Signed versions of the Montgomery values in a Montgomery computation are used to avoid the conditional addition and subtraction that can leak information, for example, using a two's complement representation.
