  • Patent number: 9464766
    Abstract: A facade light having a housing for accommodating a lighting device, operating devices and terminals, including light-emitting diodes as the lighting device and lenses for distributing the light emitted by the light-emitting diodes, wherein at least two light-emitting diodes are combined to form LED clusters (1) and a lens (2) is assigned to each LED cluster. The light emitted by the light-emitting diodes of the LED cluster passes through the lens, which is configured in such a way that it generates an elliptical distribution of light. The housing is divided into at least two sections, the first section having space for operating devices and a second section, to the side, containing at least one LED cluster and each LED cluster being coupled to a device for dissipating the heat that arises during operation.
    Type: Grant

  • Patent number: 7179929
    Abstract: Processes for preparing conjugated fatty acid glycerides comprising: (a) isomerizing a fatty acid lower alkyl ester corresponding to the general formula (I) in the presence of a basic catalyst at a temperature of from 100 to 160° C., to form a conjugated fatty acid lower alkyl ester: R1CO—OR2??(I) wherein R1CO represents an acyl radical having from 16 to 22 carbon atoms and at least two carbon-carbon unsaturations and R2 represents an alkyl radical having from 1 to 4 carbon atoms; and (b) transesterifying the conjugated fatty acid lower alkyl ester with glycerol to form a conjugated fatty acid glyceride, wherein a lower alkanol corresponding to the general formula R2OH is formed, wherein R2 is as defined above, and the lower alkanol is continuously removed from the transesterification reaction; are described.

  • Publication number: 20060189817
    Abstract: The present invention relates to a process for the production of conjugated linoleic acid, in which (a) linoleic acid lower alkyl esters containing 1 to 5 carbon atoms in a linear or branched alkyl chain are isomerized in the presence of alkali metal alcoholates, (b) the then conjugated linoleic acids are released from the ester after saponification, and (c) the free linoleic acids are subjected to crystallization. The crystallization step of said method provides a cost-effective option for producing conjugated linoleic acids with a high purity and excellent storage stability, in particular in low temperatures.
