Abstract: A longitudinal cavity is defined in the fixed longitudinal support (2) preferably presenting a square section (7) within which a main sliding cursor (6) is held to which at least one auxiliary cursor (10) is associated, the two cursors together are suited to bearing rollers (8) that can slide along four races (9) coinciding with the sides of said longitudinal cavity set with a diagonal coinciding with the action line (II—II) of the load (P) supported by the linear guide (FIG. 3).

Abstract: The level of an unsaturated cyclic imine (I) of the formula (I) where R1 is alkenyl having 3, 4, 5, 6, 7, 8, 9, 10, 11 carbon atoms belonging to the ring system, in a mixture comprising hexamethylenediamine and an imine (I) is reduced by electrochemical conversion of an imine (I) in a mixture comprising hexamethylenediamine and an imine (I) in the presence of solvated protons into a saturated cyclic amine of the formula (II)

Abstract: The invention relates to the use of crosslinked polyvinylpyrrolidone as an additive to compact, particulate detergents and cleansers for the purpose of increasing the rate of disintegration thereof when brought into contact with water, to the particles of crosslinked polyvinylpyrrolidone having a particle size of from 50 to 400 &mgr;m, to a process for the preparation of the compact, particulate detergents and cleansers, and also to the compact, particulate detergents and cleansers themselves.

Abstract: In a process for preparing polymers of vinylaromatic compounds at from 0 to 150° C. in the presence of metallocene complexes as catalysts, the polymerization is carried out at a pressure of from 5 to 300 bar in the presence of aliphatic C1-C4-hydrocarbons using a coordination complex selected from the group consisting of strong, uncharged Lewis acids, ionic compounds having Lewis acid cations and ionic compounds having Bronsted acids as cations as cocatalyst.

Abstract: Carotenoid formulations comprising a mixture of &bgr;-carotene, lycopene and lutein, and the use thereof in human and animal foods, cosmetics and pharmaceuticals.

Abstract: A process for the preparation of an O-alkylisourea of the formula I, where R1 is C1- to C20-alkyl, in the form of an acid addition salt, in which urea and an alkyl-transferring reagent, if required dissolved or suspended in a diluent, are reacted at 40-200° C. in a continuously operated reactor, is described. The diluent is preferably a recycled part-stream of the O-alkylisourea acid addition salt obtained.

Abstract: The present invention relates to a process for preparing alkyl, alkenyl and alkynyl chlorides from alcohols by reaction with a chlorinating agent in the presence of a catalyst, wherein the catalyst is a urea compound.

Abstract: The invention relates to an automatic pipetting apparatus, having a drive for moving a pipetting instrument from a source site to a target site, in which apparatus end stops (8-10, 14, 15), which can be finely adjusted automatically, for the movements of the pipetting instrument (1) generated by the drive are provided at the source site and/or the target site.
