摘要： The present invention provides a method of converting a hydroxy group in alcohols containing an electron withdrawing group into perfluoroalkanesulphonate and fluorosulphonate esters, which are good leaving groups, with inversion of configuration where the hydroxyl-bearing carbon is chiral. The method consists of converting said alcohol to an O-N,N-dialkylsulphamate ester and reacting said O-N,N-dialkylsulphamate ester with a perfluoroalkanesulphonic acid or fluorosulphonic acid. Such a method is useful for preparing chiral compounds for pharmaceutical and agrochemical use.

摘要： A system for preventing a wheel lockup of an airplane's landing gear comprising a hydraulic pump driven by the wheel, the pump's discharge is being directed through a metering circuit which permits fluid to flow through it at a rate which is proportional to the airplane's ground speed, the pressure created between the pump and the metering circuit is directed to a brake unit which applies brake torque to the wheel.

摘要： A hydraulic booster motor adapted to be connected to and to activate a vehicle's master cylinder which is connected to a hydraulic braking system, the booster's valve body defines two coaxial bores, the large bore carries a power piston which is slidable in it and powertransmittingly connected to the primary piston of the master cylinder, and the small bore carries a reaction piston which is slidable in it and powertransmittingly connected through a linkage to the brake pedal of the vehicle, the booster valve body, together with the two pistons it carries, define a variable volume into which fluid flow is forced through an inlet port and which leaves the variable volume through an exhaust passage which is restricted when driver pushes the brake pedal with his foot.
