  • Patent number: 9499681
    Abstract: Epoxidized fatty acid alkyl esters and methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing fatty acid alkyl esters with an acid and a peroxide. Epoxidation can be performed under controlled reaction conditions to provide epoxidized fatty acid alkyl esters having an iodine value in the range of from 4 to 15 g I2/100 g of epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizer compositions, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.

  • Patent number: 9403965
    Abstract: The present disclosure is directed to a plasticizer, polymeric compositions containing the plasticizer, and conductors coated with the polymeric composition. The plasticizer includes (i) an epoxidized fatty acid methyl ester, (ii) an epoxidized natural oil, and (iii) an epoxidized tallate ester. Polymeric compositions containing a polymeric resin and the plasticizer exhibit a weight loss less than 50 mg/cm2 after exposure to 100° C. for seven days. Conductors coated with the polymeric composition (containing the plasticizer) pass the low temperature unwind test of UL719 and exhibit a weight loss less than 50 mg/cm2 after exposure to 100° C. for seven days.

  • Publication number: 20150252014
    Abstract: Methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing a natural oil with an acid and a peroxide. Residual acid in the epoxidized natural oil is not neutralized, such as with a base, prior to esterification to produce the epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizers, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.

  • Patent number: 9128785
    Abstract: A method for managing a shared buffer between a data processing system and a network. The method provides a communication interface unit for managing bandwidth of data between the data processing system and an external communicating interface connecting to the network. The method performs, by the communication interface unit, a combined de-queue and head drop operation on at least one data packet queue within a predefined number of clock cycles. The method also performs, by the communication interface unit, an en-queue operation on the at least one data packet queue in parallel with the combined de-queue operation and head drop operation within the predefined number of clock cycles.

  • Patent number: 8843805
    Abstract: In general, techniques are described for efficiently and transparently partitioning a physical address space of a DRAM part lacking dedicated error protection circuitry to supply addressable error protection bytes for use in detecting and/or correcting bit errors elsewhere present in the physical address space. In one example, a network device includes a DRAM and a memory controller that receives a write command to write data to the DRAM. An address translation module of the memory controller logically partitions the DRAM to define a plurality of physically addressable sections that includes an error protection section for storing error protection bits and one or more data storage sections. The memory controller defines a contiguous logical address space representing the data storage sections. A DRAM controller of the network device communicates with the DRAM to store the data to one of the data storage sections in accordance with the contiguous logical address space.
