Method for separating lead from a lead coated cable
Abstract
Abstract APPARATUS AND A METHOD FOR SEPARATING A NUMBER OF DIFFERENT MATERIALS INITIALLY BOUND TOGETHER AND SEPARABLE FROM EACH OTHER BY THE APPLICATION OF HEAT. THE BOUND MATERIALS ARE MOVED INTO AND THROUGH A MASS OF MOLTEN LEAD ALONG A PREDETERMINED PATH AND FOR A TIME SUFFICIENT TO CAUSE THE SEPARATION OF THE MATERIALS FROM EACH OTHER. THE TEACHINGS OF THE INVENTION ARE ESPECIALLY ADAPTED FOR REMOVING THE COATING FROM ELONGATED LEAD-COATED MEMBERS, SUCH AS ELECTRICAL CABLES. THE MOLTEN LEAD IN THE LEAD MASS IS CIRCULATED TO PROVIDE A SUBSTANTIALLY UNIFORM TEMPERATURE DISTRIBUTION THROUGHOUT. ALSO, VIBRATORY MOTION IS IMPARTED TO THE MOLTEN LEAD TO FACILITATE THE SEPARATION OF THE MATERIALS FROM EACH OTHER. THE DROSS OF THE MOLTEN LEAD IN THE LEAD MASS IS KEPT FROM BEING MOVED OUT OF THE LEAD MASS WITH ONE OF THE MATERIALS AFTER THE MATERIALS HAVE BEEN SEPARATED FROM EACH OTHER.
