Filed: 1986-10-28
Abstract: Dispositif et procédé de fabrication et d'utilisation de celui-ci pour enlever le ciment prothétique d'un os sur lequel une articulation artificielle (par exemple de la hanche) doit être remplacée. Le dispositif coupe le ciment prothétique dans un plan longitudinal de la cavité prothétique jusqu'à la profondeur totale du ciment mais pratiquement sans entamer l'os. Le dispositif comporte une tête de sciage (8) effectuant un mouvement de va-et-vient, que l'on fait avancer dans le sens longitudinal de la cavité et qui est maintenue dans le plan longitudinal de celle-ci au moyen d'un élément de guidage (1) pendant l'opération de coupe du ciment (10). La tête de sciage (8) est orientée transversalement par rapport au ciment de sorte qu'elle ne coupe que jusqu'à une certaine profondeur définie par le profil d'un gabarit (6). Ce profil est basé sur des données obtenues par rayons X avant le début de l'opération.

Abstract: L'invention concerne des modifications du jeu de Baccara qui permet d'ajouter des mises, ce qui n'est pas le cas dans le jeu normal. Dans la première forme du jeu modifié, le joueur peut miser sur deux ou trois sorties de pots, et si le premier de ces pots sort, on utilise un marqueur pour indiquer que les joueurs ne peuvent plus miser. En cas de deuxième pot, le marqueur indique que les personnes ayant misé en direct sur le double pot touchent la mise. Si le troisième pot sort, le marqueur est de nouveau changé pour indiquer l'état avant que les joueurs ne touchent leur mise. Le jeu prévoit également un système de cagnotte qui peut également utiliser des pots ou d'autres résultats rares, et est prévu pour que les joueurs touchent leurs mises pour divers événements qui permettent d'obtenir une cagnotte. Sur la série prédéterminée d'événements déclenchant la cagnotte, les joueurs ayant misé en direct touchent une partie ou la totalité de la cagnotte.

Title: Decoupage par jet de plasma
Inventor: RAMAKRISHNAN SUBRAMANIA
IPC: B23K10/00
Filed: 1998-09-08
Abstract: L'invention concerne un procédé et un appareil pour couper un matériau à l'aide d'un jet de plasma assurant une uniformité améliorée le long de la longueur de coupe, en dépit des variations de la vitesse de coupe. Cela est réalisé en conférant des impulsions au courant de l'arc de plasma et en faisant varier ces impulsions de manière dynamique. Ainsi, la quantité de mouvement de l'arc de plasma peut être maintenue à une valeur sensiblement constante tandis que la quantité d'énergie fournie par le jet peut varier de manière contrôlable. Il est possible de faire varier les impulsions en fonction d'un ou de plusieurs paramètres parmi la vitesse de coupe, l'angle d'éjection d'un courant de matériau lors de la coupe; la taille des gouttelettes du matériau éjecté, l'intensité ou le schéma spectral de lumière émis par le jet de plasma et l'interface du matériau, et la tension de l'arc. Il est possible de faire varier les impulsions en modifiant un ou plusieurs éléments parmi la fréquence d'impulsion, le facteur de marche, la valeur supérieure du courant d'impulsion et la profondeur des impulsions.
