  • Method and device for determining a force exercised by the ground on a wheel
    Patent number: 7055917
    Abstract: A device and method are provided for determining a longitudinal force (Fx) exerted on a wheel of a motor vehicle by a ground surface supporting the wheel, the vehicle including connections means which connect the wheel to a body of the vehicle. An actual force (FAX) is measured at the level of at least one measurement point in the connection means. A force (FDx, Fx) is calculated which results from a transmission via the connection means from the at least one measurement point to the wheel, of a body-associated force (FADX, FAX), which depends at least on the actual force. The longitudinal force (Fx) exerted on the wheel by the ground surface is calculated as a function at least of the force (FDx; Fx) resulting from the transmission of the body-associated force.

  • Ruthenium catalysts and their use in the asymmetric hydrogenation of cyclopentenones
    Patent number: 5874600
    Abstract: A catalyst of ruthenium (II) which includes bidentate phosphine ligands. The catalyst is obtainable by a process which includes the steps of treating equimolar amounts of an appropriate Ru(II) complex and a bidentate diphosphine ligand with an acid of formula HX, wherein X is a non-coordinating anion. The acid is used in a ratio which does not exceed 2 molar equivalents per mole of Ru(II) complex and the treatment is carried out in a non-coordinating or weakly coordinating solvent and under an inert atmosphere. This catalyst is useful for the preparation of the preferred isomer of HEDIONE, having the (+)-(1R)-cis-configuration.
