  • Patent number: 10011550
    Abstract: A method for preparing high-content conjugated linoleic acid (CLA) through purification of vegetable oil includes alcoholysis, purification and isomerization of vegetable oil. Alcoholysis is for preparing corresponding methyl ester or ethyl ester with glyceride; purification of methyl ester or ethyl ester is for obtaining methyl linoleate or ethyl linoleate of content over 85% through silver-based silica gel column chromatography; high-content CLA is obtained after alkali-catalyzed conjugation of methyl linoleate or ethyl linoleate, and CLA products are prepared as needed. This invention changes the status quo of preparing high-content CLA with safflower oil alone, expands sources of CLA, and develops an efficient technology for separation and purification of linoleic acid.

  • Patent number: 9825584
    Abstract: Apparatus and techniques for controlling measurement of an electrical parameter of an energy source can be used to obtain information for use in enhancing a power transfer efficiency between the energy source and a load. For example, during a first measurement cycle, information indicative of the electrical parameter of the energy source can be obtained using a measurement circuit during a first sampling duration in which the load is decoupled from the energy source. The information indicative of the obtained electrical parameter can be compared to a threshold. In response to the comparing, a different second sampling duration can be determined for use in obtaining information indicative of the electrical parameter during a subsequent measurement cycle. The information indicative of the electrical parameter of the energy source includes information for use in enhancing the power transfer efficiency between the energy source and the load.
