    摘要: The present invention generally relates compositions and methods for the preparation of three-dimensional bodies e.g., green bodies, ceramic-loaded green bodies, and polymer matrix composites by the controlled, sequential deposition of layers of material upon one another The method for preparing a green body comprises depositing a liquid composition having a viscosity of at least about 10 poise and comprising thermally-polymerizable components onto a base in a predetermined pattern to form a layer of the liquid composition on the base. Subsequently, at least one further layer of the liquid composition is deposited on a previously-formed layer in a predetermined pattern to form a multi-layered intermediate and, then, the multi-layered intermediate is heated to cause the thermally-polymerizable components to polymerize, providing the three-dimensional green body. Another method of the present invention provides a method for reinforcing a green body with fibers. More than simply reinforcing the body, however, this particular aspect of the present invention allows the alignment of reinforcing fibers in the body to be controlled. A further aspect of the present invention is the discovery of a novel composition which may be used to provide a three-dimensional polymer matrix composite using free-formation methods. This composition comprises at least one urethane acrylate oligomer, at least one vinyl monomer, and has a viscosity of at least 10 poise.

    摘要: A method is provided for the continuous production of treated waters using a staged, tapered array membrane plant by a process of process-logic-controlled (PLC) stage or stage increment isolation and removal from service, washing and return-to-service concurrent with the continued operation of all other stages and/or stage increments of the plant. Specifically, there are plant mounted input/output sensors that supply the PLC with the data required to identify the location and degree of “fouling” of the individual stages or stage increments of a tapered array membrane water treatment plant, where fouling is defined as a loss of water flow through a membrane surface at a given pressure when compared to a water flow standard for the surface. When a stage or stage increment of a plant is defined by this process to be “fouled,” the PLC commands the initiation of a sequence of automated valve openings and closings to a) remove the fouled stage or stage increment from feed water treatment service, b) to flush and wash the stage or stage increment, and c) to return the stage or stage increment to feed water treatment service. Optionally the PLC function can be extended to include the monitoring and control of ancillary valves and a variable-frequency-drive feed water pump to command the parts of a plant that remain on-line during the process of a stage or stage increment wash to continue to produce more, or less, or volumetrically identical amounts of membrane water treatment process permeate by combinations of valve re-settings, pump speed adjustments, and stage-to-stage intermediate water diversion.
