Typically, the electromagnetic radiation is radio frequency radiation which is preferably in the range of 500 kHz to 500 MHz. The end (22) of the first electrode (12) may be curved in order to allow access to the cornua regions of the uterine cavity and to improve endometrial contact.

Abstract: Outil de type ''push-pull'' pour fixer des attaches en plusieurs éléments (16), comprenant un piston (10) qui va et vient dans un cylindre (12) en fonction des forces hydrauliques appliquées de part et d'autre du piston (10). L'un des fluides utilisés est un mélange moussant air-huile qui fonctionne essentiellement comme un transmetteur de force liquide incompressible tout en étant quelque peu compressible, de manière à absorber les charges par à-coups associées aux mouvements rapides du piston. Montée dans le système se trouve une soupape de non-retour (55) pour introduire de l'air atmosphérique dans ledit mélange moussant air-huile, permettant ainsi de compenser partiellement les fuites d'huile qui pourraient survenir par inadvertance à travers le joint d'étanchéité du piston.

Abstract: Un film magnétique à base de cobalt et de platine (CoPt) d'une épaisseur de 3 000-10 000 Angstroms est déposé sur une couche de recouvrement de chrome (Cr) ou de tungstène (W) sur un substrat (16), ou est déposé directement sur le substrat (16). Le film déposé possède une composante appréciable de son axe C, qui est parallèle à la direction [00.2] se trouvant dans le plan du film. La composante de l'axe C se trouve dans le plan du film sur toute l'épaisseur du film CoPt, et le film magnétique obtenu possède une coercivité de 1300 à 2000 Oersteds, en fonction de la couche de recouvrement incorporée, lorsqu'il y en a une. Le procédé de production du film magnétique de l'invention consiste à appliquer par pulvérisation la couche de recouvrement sur un substrat (16) maintenu approximativement à température ambiante dans une atmosphère de gaz inerte. Après avoir réglé la pression du gaz et la distance (40) entre la cible de pulvérisation au cobalt-platine (34) et le substrat (16), le cobalt-platine est pulvérisé de sorte que les atomes de cobalt et de platine qui se déposent sont thermalisés tout en traversant la distance entre la cible (34) et le substrat (16). Le film ainsi déposé est magnétiquement isotrope dans le plan et peut avoir la configuration d'un aimant permanent ayant une magnétisation résultante dans le plan en l'exposant à un champ de magnétisation externe orienté le long du plan du film.

Abstract: L'invention concerne un appareil de contrôle de la tension en fonction de la température d'une batterie d'accumulation ainsi qu'un appareil de commande de la tension de charge de la batterie en fonction de la température de la batterie, de la tension et des charges du système de chargement. L'appareil de contrôle de la batterie comprend un comparateur qui permet de comparer, à n'importe quelle température dans la plage des températures de fonctionnement de la batterie, la tension réelle de la batterie à une tension de batterie de référence. La tension de référence est représentée par la courbe tension/émanation de gaz pour la batterie d'accumulation. Le comparateur reçoit un coefficient de température établi par une référence de tension interbande sensible à la température. Une pluralité d'éléments de référence interbande sensibles à la température peuvent être connectés ensemble de manière à poursuivre de manière précise toute courbe tension/émanation de gaz de la batterie à pente différente. Un appareil de commande de la tension de charge de la batterie d'accumulation est également décrit et comprend un comparateur qui compare, à toute température à l'intérieur d'une plage prédéterminée, la tension de charge réelle à une tension de charge de référence. La courbe de tension de charge de référence est une fonction des températures des composants du système de charge et des charges du système électrique. Une pluralité de comparateurs peuvent être connectés ensemble de manière à s'approcher de la courbe désirée de référence de tension de charge ou d'une combinaison de courbes.

Abstract: Circuit magnétique servant à génerer la puissance mécanique et la puissance électrique comportant un rotateur (10) situé dans un dispositif générateur de la puissance mécanique dynamique, un dispositif générateur de la puissance électrique et un dispositif d'induction magnétique à flux circulant. Le rotateur génère une force mécanique rotative à l'aide de l'énergie électrique, et reconvertit la force mécanique rotative en énergie électrique. On peut obtenir l'énergie mécanique dans le rotateur en utilisant les forces de répulsion et d'attraction du flux magnétique après la conversion de l'énergie électrique en énergie magnétique lorsque l'on obtient la force rotative de l'énergie électrique et du circuit magnétique. Le procédé d'induction magnétique consiste à utiliser l'énergie mécanique pour induire dans des induits (3, 4) le flux magnétique d'un inducteur (2) rotatif et à convertir ce flux en énergie électrique en le passant à travers les bobines (3c) enroulées autour des encoches (3a, 3b) des induits (3, 4).

Abstract: This publication discloses a dry toilet system particularly suited for multi-storey buildings. The system has the toilet seats (4) of each apartment connected via a check valve (19) and a connection branch (5) to a vertical waste stack (1). The lower end of the waste stack (1) is connected via a control valve (8) to an automatically replaced collection container (10). The toilet and household wastes are removed via the toilet seat (4), whereby they are allowed to freely fall to the lower end of the waste stack (1), and therefrom further into the collection container (10) at the opening of the cyclicly operating control valve (8). The backflow of odours from the waste stack (1) via the toilet seat (4) to the toilet space is prevented with the help of a venting duct (6) and a roof fan (7). The suction by roof fan (7) produces a vacuum in the venting duct (6) and the waste stack (1), thereby venting the odours to the roof of the building.
