Abstract

The device has two magnets (3, 4) that are separated by a superconductive plate (5) arranged inside a pipe (8). The plate is utilized for allowing passage or blocking of magnetic field of the two magnets according to a temperature of the plate. Liquid nitrogen (1) is arranged inside a container (10), where the liquid nitrogen goes up by the pipe for allowing cooling of the plate and to block magnetic field of the magnets. A compressor (6) is utilized for transporting nitrogen gas (2) in the container via another pipe (7).

Description

L'invention concerne un dispositif de moteur magnétique à aimants permanents dont le champ magnétique serait interrompu grâce au refroidissement d'une plaque supra-conductrice disposée entre les pôles opposés de plusieurs aimants permanents. The invention relates to a magnetic motor device with permanent magnets whose magnetic field is interrupted by the cooling of a superconductive plate disposed between the opposite poles of several permanent magnets.

Le dispositif est particulierement adapté pour les supraconducteurs de la famille des cuprates qui ont la particularité d'empêcher le champ magnétique de passer à basse température grâce à de l'azote liquide. Un dispositif non illustré permettra de récupérer l'énergie fournie par le mouvement des aimants (3) et (4) pendant leur phase d'attraction, lorsque la plaque (5) se réchauffera après le retrait de l'azote liquide dans le conduit (8), ainsi que pendant sa phase de répulsion, lorsque la plaque (5) se refroidira grâce au remplissage de l'azote liquide (1) dans le conduit (8). Une partie de l'énergie fournie par le mouvement de ces aimants (3) et (4) pourra être utilisée afin de recomprimer l'azote gazeux (2) qui sera récupéré dans le reservoir (9) afm de le rendre liquide pour remplir le réservoir (10). Le nombre d'aimants et de plaques supraconductrices est non limitatif. Dans la forme de réalisation selon la figure 1, la plaque supraconductrice (5) se trouvant à l'intérieur du conduit (8) ne baigne pas dans l'azote liquide (1). La plaque n'étant pas refroidie, elle laisse passer le champ magnétique des aimants permanents (3) et (4) qui s'attirent respectivement. L'énergie fournie par ces aimants permanents permettra de faire fonctionner le compresseur (6) qui enverra l'azote gazeux (2) contenue dans le réservoir (9) à l'intérieur du réservoir (10) via le conduit (7). Le bas du conduit (8) qui se trouve à l'intérieur du réservoir (10) étant en dessous du niveau de l'azote liquide (1), cela permettra à l'azote liquide (1) de remonter dans le conduit (8) lorsqu'il y aura une augmentation du volume d'azote gazeux (2) dans le réservoir (10) grâce au compresseur (6) via le conduit (7). Ce refroidissement de la plaque (5) créera un contre-champ magnétique qui repoussera les aimants (3) et (4) fournissant ainsi une certaine énergie qui pourra être récupérée par un dispositif non illustré. Le compresseur (6) permettra aussi le retrait de l'azote gazeux (2) du réservoir (10) via le conduit (7) afm de faire descendre l'azote liquide (1) du conduit (8) dans le réservoir. Ceci permettra un nouveau cycle de fonctionnement des aimants (3) et (4) qui s'attireront mutuellement. De l'azote gazeux pourra aussi être récupéré par le conduit (8) pour remplir le réservoir (9). Des vannes non illustrées pourront être placées à divers endroits du dispositif de l'invention afm de permettre le passage ou le bloquage de l'azote liquide (1) et de l'azote gazeux (2). - 2 - Dans une figure non illustrée les aimants (3) et (4) ainsi que les plaques supraconductrices pourraient être mobiles afin d'augmenter la vitesse des cycles de fonctionnement en passant d'une plaque refroidie vers une plaque réchauffée plus rapidement. Des liquides de refroidissement autre que l'azote pourront être utilisés. The device is particularly suitable for superconductors of the cuprate family which have the particularity of preventing the magnetic field from passing at low temperature by means of liquid nitrogen. An unillustrated device will recover the energy provided by the movement of the magnets (3) and (4) during their attraction phase, when the plate (5) will heat up after removal of the liquid nitrogen in the conduit ( 8), as well as during its repulsion phase, when the plate (5) will cool by filling the liquid nitrogen (1) in the conduit (8). Part of the energy provided by the movement of these magnets (3) and (4) can be used to recompress the nitrogen gas (2) to be recovered in the reservoir (9) to make it liquid to fill the tank (10). The number of magnets and superconducting plates is non-limiting. In the embodiment according to Figure 1, the superconducting plate (5) located inside the conduit (8) does not bathe in the liquid nitrogen (1). As the plate is not cooled, it lets the magnetic field of the permanent magnets (3) and (4) that attract each other pass. The energy provided by these permanent magnets will operate the compressor (6) which will send the nitrogen gas (2) contained in the reservoir (9) inside the tank (10) via the conduit (7). The bottom of the duct (8) which is inside the tank (10) being below the level of the liquid nitrogen (1), this will allow the liquid nitrogen (1) to rise in the duct (8). ) when there will be an increase in the volume of nitrogen gas (2) in the tank (10) through the compressor (6) via the conduit (7). This cooling of the plate (5) will create a magnetic counter-field that will push the magnets (3) and (4) thus providing a certain energy that can be recovered by a device not shown. The compressor (6) will also allow the withdrawal of the nitrogen gas (2) from the tank (10) via the conduit (7) to lower the liquid nitrogen (1) of the conduit (8) in the tank. This will allow a new cycle of operation of the magnets (3) and (4) which will attract each other. Nitrogen gas may also be recovered via the conduit (8) to fill the reservoir (9). Valves not shown may be placed at various locations of the device of the invention to allow passage or blockage of liquid nitrogen (1) and nitrogen gas (2). In an unillustrated figure the magnets (3) and (4) as well as the superconducting plates could be movable in order to increase the speed of the operating cycles by passing from a cooled plate to a heated plate more quickly. Coolants other than nitrogen may be used.
