Abstract

Perfeccionamientos concentradores de corriente, para calentar por inducción zonas previamente elegidas de placas metálicas, caracterizados porque el concentrado de corriente comprende un transformador, cuyo transformador comprende una horma de arrollamiento secundario de una sola espira en forma de cuerpo tubular de pared gruesa de altura elegida, cuyo cuerpo está interrumpido por una ranura axial que se extiende desde el exterior hasta el interior del mismo en toda su altura, y un arrollamiento primario de espiras múltiples enrollado alrededor del exterior de dicha horma en espira secundaria, formando puente las espiras de dicho arrolamiento primario en la citada ranura, y una pieza extrema superpuesta a un extremo de la horma en espira manteniendo con la misma una relación de conducción eléctrica, teniendo dicha pieza extrema una ranura longitudinal en toda su altura, alineándose dicha ranura de la pieza extrema con la ranura de la horma en espira, formando una parte de la ranura de dicha pieza extrema una prolongación axial de la ranura de la horma en espira.
