  • Patent number: 8865278
    Abstract: The polymeric material having oxygen barrier properties and low light transmission characteristics, in particular within the UV and visible light wavelengths and comprises (A) a polyester, (B) mineral particles, (C) a polyamide, and (D) at least one transition metal catalyst. Preferably the amount of mineral particles is not more than 26 wt % of the total weight of the material, and is not less than 20 wt % of the total weight of the material.

  • Patent number: 7473755
    Abstract: The present invention relates to an aromatic polyester composition for making stretch blow molded containers with improved strain hardening. The polyester composition according to the invention exhibits a low DEG content, a natural stretch ratio of <10, a half time of crystallization of >150 sec at 200° C. and comprises a sulfo-modified copolymer. Compared to polyesters of the prior art, the polyester of the present invention exhibits superior stretching characteristics, such as a lower natural stretch ratio (NSR), which allows for production of small PET bottles via thinner and longer parisons. Such thinner and longer parisons improve the production of small containers due to shorter cooling cycles.

  • Publication number: 20080005376
    Abstract: In a fully non-intrusive bus monitoring interface the bus under test is not affected at all by the presence of the bus monitor. Other bus devices do not recognize the monitor as it does not participate in the bus arbitration and tree identification. The bus monitor is completely invisible to the bus / devices under test as it is not assigned its own nodeID, does not transmit a SelfID packet and is not affecting the bus topology. Furthermore, the device does not add any delays into the signal propagation between two devices and has neglectable influence on signal quality. However, it still provides the necessary means to tap into the signal transmissions to detect bus symbols and convert them into suitable data patterns for subsequent data analysis.

  • Publication number: 20070160787
    Abstract: The present invention relates to a parison and container made from an aromatic polyester composition with improved strain hardening. The polyester composition exhibits a low DEG content, a natural stretch ratio of <10, a half time of crystallization of >150 sec at 200° C. and comprises a sulfo-modified copolymer. The invention further relates to a process for making small volume containers. Compared to polyesters of the prior art, the polyester of the present invention exhibits superior stretching characteristics, such as a lower natural stretch ratio (NSR), which allows for production of small PET bottles via thinner and longer pansons. Such thinner and longer pansons improve the production of small containers due shorter Cooling cycles.
