Abstract: A process for the production of a coated plasticising screw for the injection molding or extrusion of plastic material, wherein at least the wearing surfaces of the plasticising screw are coated with a metal-based alloy, comprising the following steps: coating at least said wearing surfaces with said alloy, heating the coated plasticising screw for fusing said alloy to said plasticising screw, and cooling off said coated plasticising screw, wherein in the fusing operation all the coated wearing surfaces are simultaneously exposed to a temperature which is above the melting temperature of said alloy.

Abstract: For the measurement, orientation and fixation of at least one single crystal, it is the object of the invention to ensure increased accuracy in the determination of crystallographic orientation and oriented fixation regardless of the outer geometry of the single crystals, and the fixation should guarantee a highly accurate cutting also with very hard materials such as sapphire or silicon carbide. The single crystal is adjustably positioned on a revolving table for determining the crystal lattice orientation, wherein the crystal lattice orientation is determined during at least one revolution of the revolving table based on a plurality of x-ray reflections. The orientation of the crystal lattice is carried out with reference to the determined angles of the normal of the lattice plane relative to the axis (X-X) of the revolving table as reference direction before carrying out the fixation of the single crystal and the fastening on a support oriented in reference direction.

Abstract: An automation process for the management of operating materials and/or supplies of an analyzer or analyzing system, preferably for applications in medical, environmental or food technology, comprising the following steps: (a) automatic recording of data on operating materials and/or supplies, in particular type and maximum useful life of the operating materials used, as well as types, expiry dates and quantities of the required supplies, (b) entering the desired frequency of analysis, or automatic calculation of the estimated frequency of analysis from past frequencies of use of the analyzer or analyzing system, (c) automatic calculation of the operating materials and/or supplies required per unit of time, based on the data obtained in steps (a) and (b), (d) determining an optimum point in time for ordering the required operating materials and/or supplies, (e) automated ordering of the operating materials and/or supplies via a device for remote data transmission, preferably via an internet connection.

Abstract: A flexible, extendable analyzing system for analyzing medical samples, and preferably for analysis of body fluids, is provided with one or several independent single analyzers for measuring a single parameter or parameter group each, and a computer-supported central unit with an input/output unit. The single analyzers are coupled to the central unit in a first position, i.e., the charging position, from which they can be removed and inserted in a second position, i.e., the measuring position, preferably a bedside measuring position. The single analyzers coupled to the central unit in the charging position form a multi-component analyzer.

Abstract: The invention relates to an assay for determining an analyte in a fluid sample. Three receptors are used, with formation of a quaternary or four member complex. One of the receptors is bound to a solid phase, and binds to complexes of another receptor and the analyte. A third receptor is labelled, and it, too, binds analyte. The invention also involves the use of a displacement solution to wash fluid sample from solid phase after the first portion of the quaternary complex forms, i.e., prior to binding with the labelled receptor.

Abstract: The invention involves an apparatus useful in analysis of liquid samples. At least 3 zones are provided which contain reactants which interact with the analyte and each other, leading to the detection reaction. The apparatus also has a fluid application means for reception of a liquid, and a waste zone, which absorbs excess liquid after the detection reaction has taken place. The fluid application means and waste zone are positioned at opposite ends of the apparatus.

Abstract: The head of this boring tool carries two bit holders, which can be radially adjusted to different cutting widths by tooth systems provided on sloping faces of the head and/or bit holder. To ensure that there is still reciprocal supporting of the bit holders even in the outermost adjustment range thereof, cams are provided for extending the supporting surfaces. As an alternative to or in addition to this measure, the spacing between the front end face of the head and the surface of the bit holder parallel thereto is made so small that when high cutting forces occur these surfaces are supported on one another before the elastic deformation range of the bit holders is exceeded.

Abstract: A program storage device which can be variably programmed manually. The device comprises for this purpose at least one printed circuit board having primary electrical contact surfaces and at least one secondary contact surface; a transverse board with a row of slits for each circuit board; and slide contacts which are designed for insertion into any of the slits in the transverse board for electrical connection, according to a desired program, with the primary and secondary contact surfaces.

Abstract: The daylight stability of hydroprocessed oils is improved by adding thereto (1) singlet oxygen quenchers suitably selected from the class consisting of carotenes, aliphatic amines and heterocyclic amines, and (2) certain aromatic secondary amines as antioxidants.
