Abstract

Cet appareil permet de réaliser des étranglements sur des tubes cylindriques métalliques et comporte un générateur d'impulsions, constitué par une série de condensateurs qui, au moyen d'un interrupteur rapide, décharge l'énergie emmagasinée dans ces condensateurs dans une bobine de cuivre immergée dans le milieu liquide en regard de l'étranglement à effectuer. Cet appareil se distingue en ce que les branchements électriques entre générateur et bobine sont assurés au moyen de deux tubes conducteurs coaxiaux 10 et 11, isolés l'un de l'autre et reliés, dans le milieu liquide, aux extrémités de la bobine à l'aide de deux vérins pneumatiques, la partie inférieure de ces tubes et la bobine se trouvant à l'intérieur d'un panier métallique 13 de forme cylindrique, à la partie inférieure duquel est disposé un élément 15 de forme torique, muni de perforations à sa partie supérieure et alimenté en air comprimé.This device makes it possible to achieve constrictions on metallic cylindrical tubes and comprises a pulse generator, consisting of a series of capacitors which, by means of a fast switch, discharges the energy stored in these capacitors in an immersed copper coil. in the liquid medium opposite the constriction to be effected. This device is distinguished in that the electrical connections between generator and coil are made by means of two coaxial conductive tubes 10 and 11, isolated from each other and connected, in the liquid medium, at the ends of the coil to the 'using two pneumatic cylinders, the lower part of these tubes and the coil located inside a metal basket 13 of cylindrical shape, at the lower part of which is arranged an element 15 of toric shape, provided with perforations to its upper part and supplied with compressed air.
