Symbols (y(n - L)) in a symbol sequence transmitted via a fading channel are estimated (S/< ANd >(n - L)) in an equalizer having a channel estimating filter (CEST). An error signal (e(n)) influences an adaptation circuit (10) which controls adjustable coefficients (7) so as to form a channel estimate (c1(n), c2(n), c3(n)), which is adapted during the whole of the symbol sequence. The adaptation ci...

The invention relates to a novel herbicide composition, which comprises the (S) enantiomer or racemate of a compound of the general formula (I), (I) wherein R stands for a methyl or ethyl group, as active ingredient in an amount of 0.01 to 95% by weight together with one or more solid and/or liquid carrier(s), preferably grist(s) of native or synthetic material(s) and/or with inert solv...

A method and apparatus for manufacturing an automotive tire bead (1), whereby an annular element (2) having a substantially circular section and consisting of a coiled metal wire (3) is formed by winding the wire (3) about a mandrel (17) defining a duct (9) coiling about the annular element (2). One end of a packing wire (5) of heat-shrinkable material is then inserted inside duct (9), blown along...

A device (1) for manufacturing a tire bead (2) consisting of an annular element (3) formed from a first metal wire (4) wound in such a manner as to form a number of coils packed by a second wire (6) wound about the annular element (3) and having its opposite ends (7) tied in a knot (8). An annular madrel (9) on the device (1) defines a first annular duct (38) for forming the annular element (3), a...

An apparatus (1) for manufacturing automotive tire beads (2) wherein a pair of mandrels (3) for forming respective beads (2) each present an inner ring (9) which defines part of a drum (6) for winding a continuous metal wire (7) constituting the respective bead (2), and consists of two coaxial annular bodies (10, 11) designed to move between a detached and mated position; and an outer grip ring (5...

The subject of the present invention is a connection which is installed rapidly and is capable of connecting, by simple translation, a hydraulic or pneumatic hose 2 to a component 1, comprising a screw connection 8 which has previously been screwed into the component 1.

This invention describes a clutch device with automatic disengagement in case of overloading, useful especially for the rear power take-offs of agricultural tractors, which can be inserted in a conventional clutch casing, replacing the flywheel and the mechnical clutch of the power take-off, in which means exist for commanding the automatic disengagement of the clutch by detecting variations in ma...

In atomizing a body of molten material having elevated melting point by directing the molten body as a stream into an atomization zone and directing a stream of atomizing gas into said stream to atomize and disperse it, the orifice from which the gas is delivered is positioned closely proximate the surface of the stream to be atomized, e.g. less than 0.45 inches way. A large percentage of fine par...

The invention relates to an atomisation nozzle intended more particularly for the metallurgy of metal powders and alloys by means of a high-pressure gas improved by the addition of an aerodynamic device which centres the jet of liquid and prevents it rising during or before or after its atomisation on the liquid-supply spout or on the nozzle.
