    摘要: Process for controlling the rate of change of intrinsic viscosity and transesterification during solid stating of a polyethylene terephthalate (PET) and polyethylene naphthalate (PEN) blend, with an effective amount of an ethylene glycol compound. The process enables the production of a copolymer based on predefined initial and final IV's and final transesterification level, by varying the solid-stating time and/or effective amount of ethylene glycol. In one embodiment, a relatively greater amount of post-consumer PET (e.g., 70%) having an IV of on the order of 0.72-0.73, is incorporated in the blend to provide a final IV on the order of 0.80-0.85, and a moderate, controlled level of transesterification; the blend is used to injection mold a sleeve layer of a preform. In another embodiment, a substantially transparent neck finish for a preform is made from a PEN/PET blend having an amount of ethylene glycol which enables substantial transesterification, without excessive increase in IV.

    摘要: A blood flow calibration system 500 including a computer 400 operable to determine and store calibration data for a flow meter 124, a test system 530 operable to simulate blood flow for the flow meter 124, thereby allowing the computer 400 to determine the calibration data, and a programmer 300 operable to transfer the calibration data from the computer 400 to the flow meter 124. The flow meter 124 preferably includes a power management circuit 348a,b operable to detect whether the flow meter 124 is powered. In the event that the flow meter 124 is unpowered, the power management circuit 348a,b is preferably able to supply power to a portion of the flow meter 124 in order to transfer the calibration data thereto.
