  • Patent number: 5648070
    Abstract: Biocompatible anion exchange materials are provided comprising a support having a quaternary amine moiety and a polyethylene oxide (PEO) moiety having between about 10 and about 200 repeating units covalently bonded thereto, such that said quaternary amine and polyethylene oxide moieties are substantially homogeneously distributed on said support. These anion exchange materials are useful for removing negatively charged species such as heparin from blood and other body fluids without significant removal of platelets. Methods of making and using these materials are also provided.
    Type: Grant

  • Patent number: 5383649
    Abstract: An introducing means for introducing particulate material into a molten metal, molten alloy or molten ceramic stream, or spray of droplets formed therefrom is disclosed. The introducing means has an annular introducing chamber defining an opening through which the stream may be teemed. The chamber includes an inlet, and an outlet positioned about the opening. The outlet allows particulate material to exit from the introducing chamber at a plurality of positions about the opening so that, in use, the particulate material is introduced substantially uniformly about the stream or spray. The particulate material is preferably supplied by means of a hopper, a screw feeder for feeding material to the hopper to a mixing chamber, and a transport gas for transporting the particulate material from the mixing chamber to the introducing chamber.

  • Patent number: 4295473
    Abstract: An apparatus and method in which the amount of movement of a boundary in one or more dimensions on a dynamically movable structure or a series of sequential visual representations of said structure is measured. The boundary movement is measured by the degree of shiftable movement between light and dark areas. The motion may be analyzed and quantified in terms of linear motion or area change and an electrical analog of such motion is generated in format suitable for recordation by conventional reproducing or display mechanisms, as for example, a conventional chart recorder. In one embodiment, movement in one dimension, e.g. a linear dimension, is detected but not necessarily quantified. In another embodiment, the movement in the linear dimension is detected and measured so as to provide a quantification thereof. In a further embodiment the movement is measured in at least two dimensions to provide quantification of area changes.

  • Patent number: 4014349
    Abstract: Manufacture of a smoking material by catalytic thermal degradation of carbohydrate material above 250.degree. C, especially 250.degree.-300.degree. C, until the weight of solid residue is 50-90% (especially 65-90%) of the weight of original carbohydrate material, optionally bleaching, combining with a binder and fabricating to produce a tobacco simulating material.
