L'invention concerne un mécanisme de différentiel permettant dans les virages à la roue externe au virage de rouler plus vite que la roue interne tout en maintenant la vitesse de cette dernière à la vitesse du roulement. Cette différence entre les vitesses des deux roues de traction est limitée à une valeur crête, fonctionnelle des dimensions de véhicule. Le mécanisme est constitué d'un ensemble d...

L'invention concerne une cible composite en forme de barreau, formée de poudres céramiques et destinée à âtre évaporée sous faisceau d'électrons, comportant de la zircone et au moins un stabilisant de la zircone. De façon caractéristique, ladite cible est caractérisée en en ce que ledit stabilisant de la zircone est compris avec une teneur molaire comprise entre 2 et 30% et en ce que ladite zircon...

Modular bone implants, means of assembly, and their method of use are presented.

An egg-shaped anaerobic sludge digester has upper and lower draft tubes, and an optional middle draft tube. The draft tubes are arranged so that liquid can be (1) simultaneously pumped downwards through the upper (or middle) draft tube and upwards through the lower (or middle) draft tube; (2) simultaneously pumped upwards through two or more draft tubes; or (3) simultaneously pumped downwards thro...

An improved hearing aid, and processes for adaptively processing signal s therein to improve the perception of desired sounds by a user thereof. In on e broad aspect, the present invention relates to a process in which one or mor e signal processing methods are applied to frequency band signals derived from an input digital signal. The level of each frequency band signal is computed and compared t...

A dishwasher includes a frontal frame, a tub having a plurality of walls collectively define a washing chamber, and a door pivotally mounted to the frontal frame for sealing the washing chamber. During a washing operation, sound generated by operation of a mechanical pump escapes from below the dishwasher. To minimize sound from escaping and to provide a more enjoyable environment, a sound sealing...

A process of grape seed extraction from Vitis vinifera grapes previously treated in any variety of manners is characterised in that skin and seeds are separated immediately after the work up to which the grapes have been subjected, so as to avoid and/or stop any fermentation due to the presence of skin of any other process liquids.

A method and unit (10) for flexing a flat blank having preformed fold lines (8'); the flat blank (1) is fed by a seat (12) on a conveyor (11) along a path (P1) through a flexing station (13), where a rigid folding body (18) is rolled over the seat (12) to fold the blank (1) against two fixed folding spindles (15) of the seat (12) and about the preformed fold lines (8'); and, on leaving the flexing...

The method decomposes the radio frequency signal into sub-bands by filtering, for example with a time-frequency transform. From the coefficients acquired through decomposition a matrix of spectral coefficients is obtained, from which local estimators are obtained, constituted in particular by the coefficients of the interpolating polynomials. The statistical distribution of the local estimators is...
