  • Patent number: 9382502
    Abstract: Methods are provided for refining natural oil feedstocks and producing isomerized esters and acids. The methods comprise providing a C4-C18 unsaturated fatty ester or acid, and isomerizing the fatty acid ester or acid in the presence of heat or an isomerization catalyst to form an isomerized fatty ester or acid. In some embodiments, the methods comprise forming a dibasic ester or dibasic acid prior to the isomerizing step. In certain embodiments, the methods further comprise hydrolyzing the dibasic ester to form a dibasic acid. In certain embodiments, the olefin is formed by reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters, separating the olefins from the esters in the metathesized product, and transesterifying the esters in the presence of an alcohol to form a transesterified product having unsaturated esters.

  • Patent number: 9365487
    Abstract: Methods and systems for making dibasic esters and/or dibasic acids using metathesis are generally disclosed. In some embodiments, the methods comprise reacting a terminal olefin ester with an internal olefin ester in the presence of a metathesis catalyst to form a dibasic ester and/or dibasic acid. In some embodiments, the terminal olefin ester or the internal olefin ester are derived from a renewable feedstock, such as a natural oil feedstock. In some such embodiments, the natural oil feedstock, or a transesterified derivative thereof, is metathesized to make the terminal olefin ester or the internal olefin ester.

  • Publication number: 20160152547
    Abstract: Dibasic esters (diesters) and their use in plasticizer compositions are generally disclosed. In some embodiments, the diesters are branched-chain esters of long-chain alkanedioic acids, such as octadecanedioic acid. In some embodiments, such plasticizer compositions are used to increase the plasticity of a polymer resin, such as a vinyl chloride resin or poly vinyl butyral. In some other embodiments, such plasticizer compositions are used to lower the glass transition temperature of a polymer resin. In some embodiments, at least a portion of the plasticizer is derived from a renewable source, such as a natural oil.

  • Patent number: 9235590
    Abstract: A database system may implement compression management of tables in the database system. The compression management may include determination of a pattern of usage of various database tables in the database system. Based on this pattern of usage, the database tables may be selected as candidates for compression or decompression at the appropriate time. In one example, the pattern of usage may be based on the contents of a query log of the database system. The compression management may also include evaluation of various compression strategies to apply to a candidate database table. Each compression strategy may be evaluated to determine if application to a database table or a portion of the database table would be beneficial based on various conditions. The compression management may also include consideration of each available compression strategy to be applied solely or in combination with one another.

  • Publication number: 20160005311
    Abstract: An encrypted traffic signal device controller (TSDC) and an Electronic Variable Message Sign (EVMS) at intersection roadways and related traffic intersections where the invention system is installed at traffic light intersections which will be triggered at the red light sequence where vehicles/pedestrian/cyclists are stopped. After the traffic light turns red, the time delay of the red light will trigger an audio and visual public announcement which will be of assistance to the driver and enable the driver to pay attention to the announcement without being concerned about diverting the driver's attention from driving the vehicle since the vehicle is stopped at a red light and the driver can devote his attention to reading the information provided.
