20120112021 | AGRICULTURAL MACHINE LINKAGE ARRANGEMENT - An agricultural machine including a linkage arrangement for moving an attached device. The linkage arrangement includes a first linkage having a plurality of mutually coupled connectors, a secured part, and a pivotal part. The linkage arrangement includes a second linkage having a plurality of mutually coupled connectors, a first pivotal part which can pivot together with the pivotal part of the first linkage, and a second pivotal part that is pivotal in relation thereto. The connectors of the first linkage extend from the secured part in the direction of the first pivotal part of the second linkage. The connectors of the second linkage extend from the first pivotal part of the second linkage in the direction of the secured part of the first linkage. One of the connectors of the first linkage is connected to one of the connectors of the second linkage by way of a joining connector. | 05-10-2012 |

20090186861 | Process for Production of Fatty Acids, Fatty Acid Esters and Sterolesters from Soapstock - The invention relates to a process for production of fatty acids directly from soapstock generated in the alkali refining process including the steps of (a) adding a lipase directly to the alkaline soapstock to facilitate hydrolysis of glycerides without prior neutralisation, (b) neutralizing and splitting the soaps with strong acids, and (c) separating the fatty acid phase from the aqueous phase by settling and/or centrifugation. A second embodiment is a process in which the soapstock is first neutralized and split with strong acids, followed by adding a lipase to facilitate glyceride hydrolysis, and separating the fatty acid phase. The fatty acids so obtained can be esterified with C1-C6 alcohols using a lipase that is selective for fatty acids and does not transesterify the sterolesters, and the fatty acid esters and sterolesters are separated by distillation. | 07-23-2009 |

20080242879 | PROCESS FOR ENRICHING POLYUNSATURATED FATTY ACIDS - A process for enriching and separating polyunsaturated fatty acid (PUFA) acyl groups in a fatty acid mixture, which mixture contains other non-PUFA fatty acid acyl groups, is disclosed. | 10-02-2008 |
20080248187 | MIXTURE CONTAINING FATTY ACID GLYCERIDES - A mixture containing fatty acid glycerides which has a high percentage content of PUFA acyl groups and a low percentage content of saturated fatty acid acyl groups is described. A process which enables the PUFA acyl groups in a mixture containing fatty acid glycerides (for example a fish oil) to be enriched and, at the same time, the content of saturated fatty acid acyl groups to be maintained at a low content is described. The process is a hydrolytic process or an alcoholysis in which the fatty acid acyl groups to be enriched are hydrolytically or alcoholytically released from the fatty acid glycerides slowly, if at all, the process being carried out in the presence of a lipase. | 10-09-2008 |
