<p>Pneumatic rams inside ovens have hitherto been used to thermocompression bond metal sealing components (8, 9) to the alpha alumina ceramic lid (15) of a sodium sulphur cell. This invention discloses a spring loaded jig utilising disc springs (7). The jig comprises a pair of bayonet fastened separable portions (1, 5). The components to be sealed are first loaded in the jig, compressed together and then placed in an oven.</p> |
