Abstract: A propulsion system for using a pair of electric induction motors to power a pair of vehicle drive wheels. The motors are driven by pulses of electric current from a common dc bus. The inductance of stator windings cause electric current to power the motors during the time between pulses so power from the dc bus is low. When a vehicle is making a tight turn, an inside motor provides an electric current to the dc bus to supply additional power to an outside motor. Speed and steering signals operate the electric motors and control speed of an engine and an alternator which supply power to the dc bus.

Abstract: Crystallizable pyrethroid isomer or enantiomer pairs are converted to more pesticidally active isomers by contacting a hydrocarbon slurry of the starting isomers with a base and a catalyst, the catalyst being substantially soluble in the slurry and selected from a quaternary ammonium compound, a quaternary phosphonium compound and a crown ether, agitating the slurry while maintaining a temperature effective for conversion, and recovering the resulting isomers. The tendency to form benzoin ester by-product is reduced by including in the slurry a weak base, an aldehyde scavenger such as a metabisulfite, and/or a tetraalkyl(C1-C5)ammonium halide catalyst dissolved in an aprotic solvent such as an organic nitrile. The process typically is effective for enriching cypermethrin, cyfluthrin and (cyano)(3-phenoxyphenyl)methyl 3-(2,2-dibromoethenyl)-2,2-dimethylcyclopropanecarboxylate in the more active species.
