Abstract: A circuit breaker, in particular of a power breaker, having a busbar which is mounted so as to be movable between a closed position and an open position. The busbar, a trip device and a hand lever are coupled by means of the mechanism in such a way that, when the hand lever is moved from the first position into the second position, the busbar is moved from the open position into the closed position. Upon tripping of the trip device, the busbar is moved from the closed position into the open position, and the hand lever is moved from the second position into the first position if it is not blocked. When the hand lever is moved from the second position into the first position, the busbar is moved from the closed position into the open position regardless of whether the busbar is blocked in the closed position.

Abstract: The present invention provides methods for utilizing blended compositions of acetonitrile and toluene as organic wash solvents in the production of a synthetic oligonucleotide, the blended compositions producing higher synthetic oligonucleotide yields than a pure acetonitrile wash solvent. The method also provides a process for removing one or more impurities from the acetonitrile and toluene containing wash solvent received as a waste stream from the oligonucleotide synthesis process. The process includes adding at least one of an iodine reactive compound, a sulfur reactive compound and/or an acidic reactive compound to the waste stream, and fractionating the waste stream. The fractionation produces an overhead fraction and a bottom fraction where the overhead fraction includes the acetonitrile and the toluene, and the bottom fraction includes the one or more impurities.
