20140155636 | PROCESS OF SEPARATING CHIRAL ISOMERS OF CHROMAN COMPOUNDS AND THEIR DERIVATIVES AND PRECURSORS - The present invention relates to a process of separating chiral isomers of chroman compounds, particularly tocopherols and tocotrienols as well as the esters and intermediates thereof. It has been found that this process allows a separation of the desired isomer with a higher yield and enables the use of the non-desired isomers in a very efficient way. Said process is particularly useful when implemented in an industrial process. Furthermore, it has been found that this process allows using isomer mixtures as they result from traditional industrial synthesis. | 06-05-2014 |
20130200046 | ELECTRICAL CIRCUIT BREAKER - The invention relates to an electrical circuit breaker comprising an arc formation chamber and an arc extinguishing chamber, the arc formation chamber being at least partially bounded by a side flange or at least a part of a side wall consisting of a polymeric composition comprising a thermoplastic polymer, a triazine based flame retardant, at most 0-5 wt. % of phosphorous or halogen containing flame retardants, and 0-15 wt. % of a reinforcing agent, wherein thermoplastic polymer comprises a polyamide with a melting temperature of at least 260° C. and the triazine based flame retardant comprises at least 20 wt. % of melam, wherein the weight percentages (wt. %) are relative to the total weight of the polymeric composition. | 08-08-2013 |
