    摘要： The invention relates to the removal of viruses from aqueous solutions, as a rule protein solutions, by ultrafiltration. This entails the viruses to be removed being increased in size by incubation with a high molecular weight receptor binding thereto, preferably a specific antibody, so that, on the one hand, the separation effect is improved and, on the other hand, a larger pore diameter which can now be chosen for the filters used also makes it possible for smaller viruses to be separated from larger protein molecules present in protein solutions, and, where appropriate, the filtration rate is increased.

    摘要： Iron powder of high compressibility and low bulk density is made by atomizing a stream of molten steel by means of a conical jet of water at a rate in excess of 10 cubic meters water per metric ton of steel, the half cone angle is between 40.degree. and 60.degree., preferably 45.degree.; and air suction is provided in a region upstream from the cone, adjacent to the stream at a pressure of 0.02 to 0.20 bars below ambient, by means of a length adjustable tube extending down from the nozzle chamber. The powder is reduced at 1,000.degree. C. to 1,200.degree. C., and the resulting cake is broken up to obtain a powder having a particle size distribution with a higher content of larger particles than the powder immediately resulting from the atomization.

    摘要： A process and an agent for the sanitization of tissues or cell cultures and also of materials and equipment which can be contaminated with viruses are described. For sanitization, a solution of a substituted phenol or of a substituted phenol ether is employed here which as substituents carries one or two saturated or unsaturated hydrocarbon radicals which in each case can have up to 4 carbon atoms.
