L'invention concerne un procédé, de repérage de l'orientation par rapport à un système de coordonnées fixes d'un système de coordonnées non fixe d'un objet (VM) piloté pour corriger la direction d'avance. L' objet piloté, (VM) est lié rigidement à un corps tridimensionnel (ONK) pourvu d'éléments optiques formant des points de référence optique (LQ1 - LQ5). Au moyen d'une unité, de prise de vues...

In the system, rows of articles (1) are each assigned their own display module (5) which is fixed magnetically to the edge of the rack. The modules are supplied with solar electricity and have a display (5a) which shows goods to be picked. The modules also have a module for incrementing and decrementing goods. The modules (5) on a number of racks are swept by an infrared unit (7.1) mounted on a mo...

The stamp is made by isolating by means of ultraviolet rays a section of a photopolymer which is hardened by the effects of the rays and then removing the non-hardened zones. The isolation is provided by a mask of continuous film (5) carrying a negative version of the motif to be created on the stamp, and placing the film between the source (7) of UV rays and the photopolymer The negative version ...

A process whereby a composition comprising polydimethylsiloxane emulsion in water, is applied to an elastomeric polymer surface, such as a rubber balloon. The surface is first stretched to enable absorbtion of the composition, providing protection against oxidation and otherwise enhancing the appearance and performance of the balloon. In addition, the process provides a method of applying colours ...

The method makes it possible to monitor a three-dimensional scene and to detect anomalies. A three-dimensional, geometric reference model of the said scene is constituted associating, with each scene, corresponding points in the field of at least two sensors placed at a distance from one another and sensitive to a radiometric parameter (such as the brightness) of the scene. The real scene is perio...

PROCESSO DI (CO)POLIMERIZZAZIONE RADICALICA DI MONOMERI OLEFINICI FLUORURATI, EVENTUALMENTE IN ASSOCIAZIONE CON UNA O PIU' OLEFINE NON FLUORURATE, IN CUI I MONOMERI VENGONO (CO)POLIMERIZZATI IN EMULSIONE ACQUOSA, IN PRESENZA DI UN TRASFERITORE DI CATENA IDROGENATO SCELTO TRA IDROGENO, IDROCARBURI E FLUOROIDROCARBURI ALIFATICI C1-C20, E DI UN ALCOL ALIFATICO A CATENA RAMIFICATA C3-C12 CARATTERIZZAT...

If the mains voltage fails during operation of a spin dryer, the washing drum can stop. The washing falls to the base of the drum and is no longer uniformly distributed. When the power returns, the machine accelerates to the full rated spin dryer rotation speed. In this case, washing unbalances occur which lead to damage to the machine. In order to prevent this, a small contactor is mounted on the...
