Abstract

Patente de Invenção: <B>''ELEMENTO FUSìVEL''<D>. Um elemento fusível é provido que inclui partes de interajuste cooperantes cercadas por material de fusão. As partes de interajuste cooperantes são arranjadas de modo a colocar uma força compressiva sobre o material de fusão em resposta à separação experimentada das partes de interajuste. Ademais, o arranjo também reduz as forças sobre o material de fusão. Em resposta a uma condição de tempo-corrente predeterminada, o material de fusão se amacia suficientemente para permitir a liberação e a separação das partes de interajuste.
