Abstract: Inventors:  MICHAEL A. SHEARER             PAMELA K. SASAGAWA and RONALD H. HEIN         Invention:  IMPROVED METHOD OF PREPARING     Abstract of the Disclosure There is disclosed an improved method for separating one of alpha-1-proteinase inhibitor (also known as alpha-1 anti-trypsin) and antithrombin-III from an aqueous solution of plasma proteins containing the same, such as from Cohn Fraction IV-1, Cohn Fraction IV, reworks of Cohn Fraction IV and IV-l, Cohn Effluent II & III and Cohn Effluent I. The method includes the steps of first holding an aqueous solution of plasma proteins containing one of alpha-l-proteinase inhibitor and antithrombin-III in a relatively large volume of buffer solution as solvent and at a pH adjusted to be relatively basic when compared to conditions heretofore known, and at a temperature in the range of from 2 - 50° C for a period of about 0.2 - 24 hours.  Following the above treatment, alpha-1-proteinase inhibitor and antithrombin-III are obtained by applying conventional techniques to the resulting solution.  Accordingly, the solution is then mixed with a polyalkylene glycol, e.g. polyethylene glycol, in the range of from as low as 8% to as high as 23% (w/v) based on volume of solution to selectively precipitate unwanted proteins.  The alpha-1-proteinase inhibitor is then separated from the supernatant solution by adsorption on an anion exchange resin or by precipitation by further addition of a poly-alkylene glycol, e.g. polyethylene glycol.  The method of the invention provides an improvement in the yield of alpha-1-proteinase inhibitor.

Abstract: SYSTEM FOR REMOVING LIQUID FROM               SLURRIES OF LIQUID AND                 PARTICULATE MATERIAL     Abstract In order to separate liquids from slurries containing particulate material, and particularly from slurries of water and spent ion exchange materials which are used for water conditioning in the operation of nuclear power plants and must be disposed of without any significant volume of free standing water therein, a vessel is provided which is filled with the slurry.  The bottom of the vessel is conical and defines a region for the collection of water which passes thereto radially through a structure which filters the water and supports a bed of the particulate material thereon.  A discharge tube extends longitudinally of the vessel into the region.  A level sensor is disposed alongside the tube. A passage into the top of the vessel is provided for blowing air through the bed to force interstitial water through the bed into the region.  A system of pumps and blowers is operated in accordance with the level of liquid and solid material in the vessel so as to provide for discharge of the liquid collected in the region, the formation of a tightly packed bed of particulate material and the blowing of air through the bed after substantially all the water has been discharged so as to free additional water and enable it to be discharged, thereby removing the liquid from the slurry and de-watering the material in a relatively short period of time to the extent required by governmental regulations for the disposal of low level radioactive waste materials (radwaste), for example in eight hours, and providing efficient utilization of the volume of the vessel in preparation for storage.
