Abstract: The present invention relates to the field of catalytic hydrogenation and, more particularly, to the use of Ru complexes with bidentate ligands, having one amino or imino coordinating group and one phosphino coordinating group, in hydrogenation processes for the reduction of esters or lactones into the corresponding alcohol or diol respectively.

Abstract: The object of the present patent application are 3-aminophenol derivatives of formula (I) or the physiologically tolerated, water-soluble salts thereof wherein R denotes a heterocyclic aromatic 5-membered ring of formula (Ia) and colorants based on a developer-coupler combination and containing these compounds.

Abstract: The object of the present patent application are agents for dyeing keratin fibers based on a developer-coupler combination and characterized in that they contain at least one 3-aminophenol derivative of formula (I) or a physiologically compatible, water-soluble salt thereof wherein R1 denotes a group of the formula ?or a group of the formula ?as well as novel 3-aminophenol derivatives.

Abstract: The invention relates to an agent for colouring fibres (A). Said agent is produced by mixing two constituents (A1) and (A2), and is characterised in that the constituent (A1) contains at least one quinonimine derivative of formula (I), and the constituent (A2) contains at least one compound from the group consisting of aromatic amines and phenols. The invention also relates to a method for colouring keratin fibres using the inventive agent.

Abstract: The present invention concerns substituted benzylic nitrites substituted with lower linear alkyl or alkylene groups. These compounds are useful perfuming ingredients, and can impart odor notes of the floral-green type. The invention concerns also the perfuming compositions or perfumed articles associated with the compound.

Abstract: The charging voltage U.sub.L of the battery being charged is sensed and amplified by an amplification factor. The amplification factor is determined by the sensed charging voltage. This provides automatic scaling of the charging voltage. The amplification factor K can be repetitively or continuously adjusted during battery charging. The time behavior of the input signal is monitored. The monitoring unit determines whether the time behavior of the input signal fulfills predetermined or given criteria. When a criterion is met, a check-result signal is generated, which controls charging, for example, by stopping charging when the time behavior indicates charging is completed. Time behavior is monitored by monitoring a second order time derivative of the input signal. The monitoring unit performs optimally within a certain magnitude range. Therefore, the amplification factor is adjusted to set the input signal at a magnitude within that range.

Abstract: Boxes with compartments for individual articles that can be assembled in a flexible manner include a pair of box parts each having at least one hinge portion in which hinge knuckles alternate with open sections or recesses. A knuckle is located at one end of the hinge portion and, at the other end, an open section without a knuckle is provided.
