Claim 3
Independent Claim
95 words
AN APPARATUS FOR SHEARING A MOVING THIN WALLED CONDUCTIVE TUBE COMPRISING A COIL SHAPED TO FORM A MAGNETIC FIELD CORRESPONDING TO THE CROSS SECTION OF THE TUBE, A COOPERATING BACK-UP MEMBER SHAPED SIMILARLY TO SAID COIL AND BEING SPACED THEREFROM FOR THE MOVEMENT OF THE TUBE BETWEEN SAID COIL AND SAID BACK-UP MEMBER, AND MEANS FOR APPLYING A PREDETERMINED CURRENT PULSE THROUGH SAID COIL OF A STRENGTH AND TIME LENGTH OF PRODUCE A MAGNETIC FIELD CAPABLE OF FORCING A LOCAL PORTION OF THE TUBE TOWARDS SAID BACK-UP MEMBER TO EFFECT A SEVERANCE OF THE TUBE.
