Abstract: The present invention relates to a wave generator. Such wave generators can be used in principle for the implementation of well-known natural methods for syntonic rebalancing of living cells, revitalisation and/or treatment of individuals, persons, animals, plants or even liquid or inert objects. The resulting products will then be able to be used for the same syntonisation purposes either by absorption or by bringing together and/or contact, which will automatically trigger, according to the laws pertaining to phenomena of vibratory resonance, harmonic syntonisations of the frequencies. This generator comprises: at least one captor resonator (1-12), at least one emitter gun (13,14) associated with one or more captor resonators (1-2) and amplifying the waves, a main hollow body (15) intended to syntonise the waves with a body (16) placed essentially at its centre on a support or stele (17) towards which the waves emerging from the emitter guns are directed. <IMAGE>

Abstract: Selon un procédé de production de catalyseurs au carbone, la réduction d'oxyde nitrique (NOx) avec de l'ammoniac est catalysée par du charbon et du coke actifs. Ces nouveaux catalyseurs au carbone présentent une activité améliorée de catalysation, donc une conversion accrue de NO. On les produit en mélangeant de la houille moulue et oxydée avec des liants, en moulant le mélange, et en le carbonisant lentement à des températures comprises entre 700° et 900°C. On l'active finalement avec de la vapeur d'eau à une température de 800°/850°C environ pendant une durée de 45 à 100 minutes, jusqu'à obtenir un degré d'activation compris entre 5 et 15%.

Abstract: Réseau en phase balayé électriquement ayant des lobes latéraux bas et une illumination d'ouverture conique, alimenté par un réseau d'alimentation (55) commun, uniforme, et comprenant une ouverture de réseau principal formée par des éléments (72-75) rayonnants principaux, ainsi que des premier et second réseaux auxiliaires formés par des éléments rayonnants auxiliaires (70-71 et 76-77). Afin d'obtenir une ouverture linéaire, les sorties provenant du réseau d'alimentation (55) sont déphasées pour orienter le faisceau vers une des localisations disponsibles du faisceau, et couplées à des localisations correspondantes des éléments rayonnants (72-75) du réseau principal et des éléments rayonnants (70-71 ou 76-77) du réseau auxiliaire. Le déphasage permettant l'orientation du faisceau provoque des gradients de phase uniformes entre les éléments du réseau respectif, et des correcteurs de phase à double état (85-88) sont prévus pour effectuer une correction afin d'obtenir des discontinuités de gradients en phase traversant les ouvertures de réseaux principales et auxiliaires. Les valeurs de couplage entre les éléments respectifs des éléments rayonnants (72-75) du réseau principal et les éléments rayonnants (70-71 et 76-77) des réseaux auxiliaires correspondants sont sélectionnés pour procurer une illumination d'ouverture désirée, telle qu'une illumination d'ouverture conique. Le réseau peut être réalisé avec des modules identiques, ce qui a pour résultat une efficacité améliorée pour un coût inférieur.

Abstract: Alors que les aiguilles des bagues à aiguilles connues présentent une section transversale circulaire, les aiguilles (1) de la bague à aiguilles (2) décrite ont une section transversale ovale, rectangulaire avec des coins arrondis, ou une forme intermédiaire entre ces deux formes. La dimension plus réduite (1a) de la section transversale des aiguilles s'étend parallèlement à l'axe de la bague. Les aiguilles (1) elles-mêmes peuvent être perpendiculairement fixées sur une bague ou former un angle alpha ne dépassant pas 30° avec le rayon (2b), alors que l'angle beta formé par la pointe doit être compris entre 15° et 45°. Ces aiguilles sont montées dans des orifices circulaires (3) dont le diamètre est quelque peu inférieur à la largeur (1b) des aiguilles, qui à son tour, est égale à quatre ou six fois l'épaisseur des aiguilles, ce qui fait que l'aiguille ne remplit pas tout le volume de l'orifice. Deux canaux (3b) restent ouverts qui peuvent être utilisés pour guider le courant d'air de transport des fibres. Ces bagues à aiguille ont une vie utile relativement longue par rapport aux bagues à aiguilles connues dont les aiguilles ont une section transversale circulaire, donc une vie utile considérablement plus longue que celle de cylindres couverts pourvus de garnitures de cadre dites tout-acier, mais au contraire des cylindres à aiguilles connus, peuvent être utilisées avec pratiquement tous les métiers à filer open-end.
