Abstract: The invention relates to a method for the production of &OHgr;-aminoalkylsulphonic acids of general formula (I), where R1 and R2=optionally substituted alkyl groups with 1 20 C atoms and n=a whole number from 2 6, whereby an amine of formula (II), where R1 and R2 have the above meanings is reacted with an alkyl dihalide of formula (III), where n has the above meaning and X1 and X2=chlorine or bromine, with addition of alkali hydroxide at a pH of 8 10. The pH is then adjusted to a value of 0 1, by addition of a hydrohalic acid and excess alkyl dihalide is separated off, before the reaction solution is adjusted to a pH of 6 7.5 with alkali liquor, alkali sulphite is added and the product (I) formed at elevated temperate.

Abstract: A roller bearing cage has cage rims (1,3) on both of its axial ends. One cage rim (1) has a circumferential inside groove (5). The other cage rim (3) carries at least one holding lug (7) that protrudes radially. The holding lug (7) interlocks into the corresponding groove (5) of another such cage, wherein roller bearing cages with two or more rows are formed as a construction unit, which can rotate relative to one another.

Abstract: A thrust washer formed from metal sheet has a flat, ring-shaped thrust portion oriented radially, an axially oriented circumferential lip extending along one of the inner and the outer diameters of the thrust portion, and a tab extending from the circumferential lip. The tab includes a radially oriented mid-portion and at least one wing-portion extending perpendicular to the mid-portion and parallel to the axis of the thrust portion such that a flat surface of the wing-portion may engage a recess of a backup member to prevent rotation of the thrust washer relative to the backup member.

Abstract: A surface coated with amino groups is produced by applying a polymerizable amine to a surface by means of a pulsed plasma. The coated surfaces obtained thereby have a high density of amino groups so that a specific binding phase can be obtained by covalently binding a partner of a specific binding pair to the surfaces coated with amino groups.

Abstract: The invention concerns a binding matrix containing a carrier material and a solid phase reactant which is adsorbed to this via anchor groups that is capable of binding to at least one free reaction partner wherein the solid phase reactant forms a dilute and essentially laterally homogeneous binding layer on the surface of the carrier material. In addition a method for the determination of an analyte in a sample solution is claimed in which a solid phase reactant is used which is a component of a binding matrix according to the present invention. In this process the specific binding reaction is preferably determined by optical reflection techniques.

Abstract: A device for the laterally resolved investigation of a laterally heterogeneous ultrathin object layer, especially for the laterally resolved detection of a change in the layer thickness of the object layer which results from a specific binding reaction of a first binding partner bound to the object layer with an unbound second binding partner. The device has a multilayer structure which extends in an investigation region and includes the object layer as first layer and a second layer adjacent to the latter, a coupler arrangement for the coupling in of excitation light into the second layer. The excitation light generates at at least one defined angle of incidence in the second layer a bound, non-radiating electromagnetic wave, from which an evanescent wave extends into the object layer. An optical imaging system is provided for the imaging of the investigation region of the object layer in an image plane at a defined angle of emergence, at which detection light is coupled out from the second layer.

Abstract: A rotogravure inking system utilizes an inking roller mounted in an ink trough and engageable with a printing cylinder. The inking roller exerts a pressure force on the printing cylinder through the use of torsion bars which are located wholly within the ink trough. A prestress can be applied to the torsion bars to impart the desired pressure force to the printing cylinder from the inking roller.

Abstract: The refractive index and thickness of ultrathin layers<1 .mu.m in thickness are determined by recording the layers, which have been applied to a solid support, by surface plasmon microscopy as a function of the angle of incidence of the incident laser beam, the method making it possible to determine layer thicknesses with a vertical resolution.gtoreq.0.1 nm and a simultaneous lateral resolution.gtoreq.5 .mu.m.
