  • Patent number: 8580201
    Abstract: Embodiments of the present invention include processing steps and subsystems, within automated-biopolymer-synthesis systems and within other automated systems for organic-chemistry-based processing, for removing reagent solutions and solvents from reaction chambers following various synthetic reaction steps and washing steps undertaken during biopolymer synthesis. Embodiments of the present invention employ any of various different types of liquid-absorbing materials to wick, or remove by capillary action, liquids from reaction chambers. Wicking-based methods and subcomponents of the present invention remove significantly greater fractions of solutions from reaction chambers than conventional methods and subsystems and, in addition, are mechanically simpler and produce fewer deleterious side effects than currently used methods and subsystems.

  • Patent number: 8567487
    Abstract: A heat exchanger plate includes one or more heat exchanger sections, each of which has an inlet and outlet. The heat exchanger sections flow one or more heat exchanger fluids therein in a first direction from the inlet to the outlet. The heat exchanger plate includes one or more process flow channels, each of which has a channel inlet point and a channel outlet point defining a line oriented in a second direction. The second direction is at an angle of ninety degrees relative to the first direction. The process flow channel is configured to flow a process fluid therein or thereon and has a serpentine configuration. The heat exchanger plate includes a temperature sensor. The heat exchanger plate includes a regulating valve positioned in each heat exchanger outlet and is configured to regulate flow of the heat exchanger fluid in response to a signal received from the temperature sensor.

  • Patent number: 8557190
    Abstract: A carbon nanotube synthesis process apparatus comprises a reaction tube in which a reaction field is formed, and a discharge pipe (32) arranged downstream of the reaction tube and discharging carbon nanotubes to the outside. A plurality of nozzles (34) are provided on the sidewall of the discharge pipe (32) in directions which are deflected with respect to the center (O) of the discharge pipe (32). When gases are discharged from the plurality of nozzles (34), a swirl flowing from the inner side surface along the inner side surface is produced in the discharge pipe (32). Adhesion of carbon nanotubes to the inner side surface of the discharge pipe (32) is prevented by the swirl flow and thus the apparatus can be operated continuously.

  • Patent number: 8476382
    Abstract: This present invention provides devices for the parallelization of the formation of droplets in a multiple droplet generator integrating two or more parallel flow-focusing devices (FFDs) with either identical, or different, geometries. In the parallel identical FFDs, emulsification generates droplets with a narrow (below 4%) polydispersity despite weak coupling between the identical flow-focusing devices. Formation of droplets in the integrated droplet generator comprising FFDs with different dimensions of the microchannels occurs with strong coupling between the FFDs and produces droplets with varying sizes and size distributions. For such devices the regime in which emulsification produces droplets with varying dimensions and a narrow size distribution have been identified. The results of this work can be used in scaling up the production of droplets and in the simultaneous production of droplets and particles with different dimensions.
