  • Patent number: 9195004
    Abstract: The disclosure relates to providing printed structures of polymer that have substantially flat printed surfaces. In one embodiment, the disclosure relates to a post-printing treatment apparatus for receiving a substrate supporting a polymer printing thereon. The polymer can be PMMA or other suitable polymer. In a related embodiment, the polymer defines a thermoplastic polymer having a glass transition temperature. The apparatus can comprise of a chamber, and input manifold, an exhaust manifold, a solvent reservoir and a gas reservoir. The solvent reservoir provides one or more solvent systems adapted to chemically bind, and potentially react, with the polymer. The gas reservoir provides one or more gases for drying the substrate and printed polymer after the solvent treatment step. In one application, a substrate having printed surface thereon is placed in the chamber and exposed to the solvent system for sufficient period of time to provide substantially flat print surfaces.

  • Patent number: 8075778
    Abstract: A method of separating a first fluid from a second fluid may include prewetting with the first fluid at least one channel defined by a separation device, the at least one channel thereby containing a column of the first fluid along its length. A combined flow of the first fluid and the second fluid may be presented to the separation device, so that the at least one channel is in fluid communication with the combined flow. Fluid pressure may be applied across the combined flow and the separation device, but the applied pressure should not exceed the capillary pressure in the at least one channel. Otherwise, the combined flow may be forced through the separation device. In this manner, the first fluid flows through the at least one channel, and the second fluid is excluded from the at least one channel, thereby separating at least a portion of the first fluid from the second fluid.

  • Publication number: 20100188457
    Abstract: In an embodiment, the disclosure relates to a method and apparatus for fault monitoring and controlling operation of a discharge nozzle in a large array of discharge nozzles. An exemplary apparatus includes a thin, thermally conductive membrane, with an integrated thin-film electrical heater. When a fixed voltage is applied to the heater, and as the heater heats, the resistance of the heater will increase which will cause a concomitant decrease in the electrical current flowing through the heater. By measuring the resistance of the heater it can readily be determined whether the device is functioning properly.
