  • Method of filtering viruses from a factor VIII solution
    Patent number: 6967239
    Abstract: Method for preparing a factor VIII solution that is essentially free of viruses and essentially devoid of vWF (von Willebrand factor) and factor VIII-vWF complexes by (a) obtaining a starting factor VIII solution devoid of factor VIII-vWF complexes; and (b) filtering the solution through a hydrophilic virus filter.

  • Process for the preparation of pigment grade iron oxides from ferrous sulphate and the resulting Fe.sub.2 O.sub.3 pigments
    Patent number: 4261966
    Abstract: Pigment grade Fe.sub.2 O.sub.3 is prepared from ferrous sulphate by a roasting process. The ferrous sulphate, partly dehydrated and granulated, is partially converted to the oxide by roasting. After elimination of soluble constituents by washing with water, the oxide is subjected to pigmentary calcination and then crushed and optionally micronized. This process makes it possible to prepare red pigments of excellent quality characterized particularly by pure tints ranging from orange-red to purplish-red. The oil absorptions are especially low. Low toxic impurity concentrations permit the use of these pigments in foodstuffs.

  • Three-dimensional shaped articles
    Patent number: 4228207
    Abstract: The present invention relates to flexible, three-dimensional articles consisting of a flexible, two-dimensional, unimpregnated, braided structure based on yarns or tows preferably having a high modulus of elasticity and possessing a varying cross-section. These articles are intermediates in the production of shaped articles which are both strong and light.

  • Absorbent products for hydrocarbons
    Patent number: 3990970
    Abstract: A pulp, i.e. an amorphous mass obtained by precipitation by means of a non-solvent, of an artificial or synthetic polymer, preferably a polyamide or polyester, is used as an absorbent for oil floating on water. Advantageously the pulp is coated with 1 to 5% of its weight of a hydrophobic and oleophilic material, especially a long chain paraffin or chlorinated paraffin.
