  • Patent number: 4199502
    Abstract: This invention relates to a method for the removal of heparin from heparin-containing blood plasma test samples using an insoluble protamine reaction product, without adversely affecting subsequent testing of the plasma for clotting time. Protamine sulfate or a combination of protamine sulfate and serum albumin is cross-linked with glutaraldehyde to form an insoluble reaction product which is capable of adsorbing heparin. According to the method of this invention, excess amounts of either of the cross-linked protamine reaction products are added to blood plasma samples containing heparin and the mixture is agitated for a time sufficient to permit adsorption of substantially all heparin present. The insoluble protamine heparin complex formed is removed from the plasma along with any excess insoluble protamine reaction product. Aliquots of the heparin-free plasma may be subjected to coagulation tests in order to determine true clotting time.

  • Patent number: 4187320
    Abstract: A two-stage process for the preparation of a chewing gum base utilizing solid elastomer is described wherein the solid elastomer is initially subjected to high intensity mixing under high shear conditions to masticate the solid until a substantially uniform, lump-free mass is obtained; followed by the step-wise addition of an elastomer solvent and an oleaginous plasticizer with continuous high intensity mixing until a substantially molten, uniform mass is obtained. In the second stage of the process, the remaining chewing gum base ingredients are added, step-wise, with continuous high intensity mixing until a uniform blend of ingredients is obtained. The second stage ingredients, which may include a non-toxic vinyl polymer, a hydrophobic plasticizer, additional oleaginous plasticizer and an emulsifier, are added step-wise in a sequence determined by decreasing order of viscosity. In a modification of the process, the hydrophobic plasticizer or emulsifier may be added with the stage one ingredients.
