  • Bioaffinity and ion exchange separations with liquid exchange supports
    Patent number: 5268456
    Abstract: Bioaffinity and ion-exchange separation methods are provided along with liquid supports utilized in these methods. The support is based on an inert carrier with ligands or binders attached to its surface through a highly fluorinated isocyanate anchor group. Methods for preparing such supports and their use in capturing neutral and charged target molecules from samples and in analytical applications are also provided.

  • Process for producing coherent films of polyacetylene
    Patent number: 4631205
    Abstract: A process for producing coherent films of polyactylene is disclosed. A support is contacted with a catalyst comprising an acidic, polar medium containing a transition metal salt, water and a borohydride. The support is then contacted with acetylene gas which forms on the support a coherent film of polyacetylene strongly adherent to the support.

  • Centrifuge apparatus
    Patent number: 3957197
    Abstract: A method and apparatus for operating a continuous flow blood separation centrifuge are provided. The hematocrit of the entrant whole blood is continuously maintained at an optimum constant value by the addition of plasma to the entrant blood. The hematocrit of the separated red cells is monitored to indicate the degree of separation taking place, thereby providing a basis for regulating the flow through the centrifuge.
