摘要： Disclosed is a system for regulating airflow velocity in a print gap region of a micro-fluid ejection device. The system includes a carrier member configured to carry an ejection head therewithin; a nozzle array configured at a bottom portion of the ejection head; and a channel member extending from a top portion of the carrier member and along a depth of the carrier member up to the bottom portion of the ejection head. Also, the channel member extends along at least a width of the nozzle array. Additionally, the channel member is configured to receive a flow of air through a slot configured at the top portion of the carrier member and to direct the flow of air from the top portion of the carrier member towards the bottom portion of the ejection head. Further disclosed is another system for regulating airflow velocity in a print gap region.

摘要： A process for the continuous production of polylactide polymers from lactic acid which incorporates removal of water or a solvent carrier to concentrate the lactic acid feed followed by polymerization to a low-molecular-weight prepolymer. This prepolymer is fed to a reactor in which a catalyst is added to facilitate generation of lactide, the depolymerization product of polylactic acid. The lactide generated is continuously fed to a distillation system as a liquid or vapor wherein water and other impurities are removed. The resultant purified liquid lactide is fed directly to a polymerization process.

摘要： A lactide polymer composition combining compositional and purity limitations and catalyst optimization or addition of stabilizing agents resulting in a melt-stable polymer is disclosed. The melt-stable lactide polymer comprises a plurality of polylactide polymer chains, residual lactide in concentration of less than 2 percent and water in concentration of less than 1000 parts-per-million. A stabilizing agent in an amount sufficient to reduce depolymerization of the lactide polymer during melt-processing or alternatively, control of catalyst level at a molar ratio of monomer to catalyst greater than 3000:1 is also included in the melt-stable composition. A process for manufacture of a melt-stable lactide polymer composition includes polymerizing a lactide mixture and adding stabilizing agents sufficient to reduce depolymerization of the polylactide during melt-processing, followed by devolatilizing the polylactide to remove monomer and water.
