  • Publication number: 20140076340
    Abstract: High-throughput production apparatuses, systems, and associated methods may include pneumatic dense phase feeding. For example, a method may involve feeding via pneumatic dense phase feeding a matrix material into a mold cavity to form a desired cross-sectional shape, the matrix material comprising a binder particle and an active particle; heating (e.g., via microwave irradiation) at least a portion of the matrix material so as to bind the matrix material at a plurality of contact points thereby forming a porous mass length; cooling the porous mass length; and cutting the porous mass length radially thereby producing a porous mass. In some instances, the matrix material may include a plurality of active particles, a plurality of binder particles (optionally having a hydrophilic surface modification), and optionally a microwave enhancement additive.

  • Patent number: 8275793
    Abstract: A method and system for maintaining isolated data in an application is disclosed which data to be selectively isolated until a data client orders the changes to be committed or abandoned. A computer-readable medium for constructing an application capable of localized data isolation is also disclosed. An application specification is used to determine which data entities should be isolated, and one or more transaction transforms are implemented for each data entity to be isolated.

  • Patent number: 4999305
    Abstract: A method for titration flow injection analysis by introducing a multicomponent sample into a carrier stream which flows into a mixing/sensing cell and titrating with a reactant more than one component of the sample by sensing a plurality of endpoints. The apparatus of the invention includes a stirring means within the mixing/sensing cell which generates helical flow within the cell so that bubbles are not retained in the cell.
