  " Boulons fusibles perfectionnés" 
L'objet de la présente invention est un perfectionnement aux boulons fusibles utilisés dans les chaudières à vapeur, tel que requis par l'article 26 du règlement général sur les appa- reils à vapeur, arrêté royal du 28 mars 1919, et applicables d'ailleurs d'une manière générale sur tous appareils contenant un liquide devant être parte à une certaine température. 



   Généralement, ces boulons fusibles oontiennent une ême en plomb, mais il a été oonstaté que le plomb est généralement vite dissout et rongé par certaines eaux et qu'il s'ensuit des ar- rêts intempestifs de la chaudière et le problème inventif oon- sistait   donc   à rechercher une matière métallique offrant une meilleure résistanoe à l'action oorrosive de l'eau tout en gar- dant les mêmes propriétés de fusibilité que le plomb. 

 <Desc/Clms Page number 2> 

      le demandeur a trouvé que le   cad@ium   répond aux différentes conditions et peut donc avantageusement remplacer le plomb dans les boulons et pastilles fusibles. 



   A titre d'exemple,le dessin annexé montre en section axi- ale un boulon fusible dont l'âme a est faite en cadmium. Du fait de remplacer le plomb par du cadmium, on obtient donc une fourniture industrielle beaucoup plus résistante et assurant le même degré de sécurité que les anciens fusibles et dont la durée d'usage compense largement le prix plus élevé que les autres matières utilisées jusqu'à présent.

  "Advanced fusible bolts"
The object of the present invention is an improvement in the fusible bolts used in steam boilers, as required by article 26 of the general regulations on steam appliances, royal decree of March 28, 1919, and applicable from elsewhere in general on all devices containing a liquid to be left at a certain temperature.



   Generally, these fusible bolts contain the same lead, but it has been observed that the lead is generally quickly dissolved and eaten away by certain waters and that there follows inopportune shutdowns of the boiler and the inventive problem exists. therefore to seek a metallic material offering better resistance to the oorrosive action of water while retaining the same fusibility properties as lead.

 <Desc / Clms Page number 2>

      the applicant has found that cad @ ium meets the various conditions and can therefore advantageously replace lead in fusible bolts and pellets.



   By way of example, the appended drawing shows in axial section a fusible bolt whose core a is made of cadmium. By replacing lead with cadmium, we therefore obtain an industrial supply much more resistant and ensuring the same level of safety as the old fuses and whose service life largely compensates for the higher price than the other materials used up to now.
