  • Publication number: 20140370090
    Abstract: Tablets and other objects are film coated by including in the tablet a film-forming polymer that is activated upon contact with an activating amount of liquid. The film-forming polymer, e.g., a cellulosic ether, is homogeneously mixed with the other ingredients of the tablet, shaped into any desirable form, loaded into a conventional coating apparatus, and sprayed or foamed with an activating amount of fluid, e.g., water, alcohol, etc., and dried. This coating process eliminates potential problems such as spray nozzle clogging, inappropriate coating fluid viscosity, and the inability to properly atomize the coating fluid. This coating process does not impart any appreciable weight or thickness gain to the tablet.

  • Patent number: 4657676
    Abstract: Sedimentation field flow fractionation apparatus having a rotor-mounted fractionation column, has detectors positioned to observe the fluids from the column while still in the rotor. Designs include parallel reference and fractionation columns having their outflows compared in a rotor-mounted fluid flow density balance. Optionally weired channel columns provide a free fluid surface for more efficient resolution. Horizontal rotational axes are preferred. Rotor-mounted fluid flow density balances are also provided which are suitable for detecting liquid density changes in the other applications, such as liquid chromatography.
