Method of manufacture of metal encased core material

Claim 1

A METHOD OF MANUFACTURING AN ARTICLE CONSISTING OF A CORE MATERIAL COMPLETELY ENCASED IN A METALLIC SUBSTANCE COMPRISING (1) PROVIDING A FIRST METALLIC MEMBER HAVING AT LEAST A FIRST SURFACE, A SECOND SURFACE, AND A THIRD SURFACE AND CONTAINING A FIRST APERTURE IN A FIRST PORTION OF SAID MEMBER, A SECOND APERTURE IN A SECOND PORTION OF SAID MEMBER, AND A PERFORATION LOCATED IN ITS THIRD SURFACE, SAID SECOND APERTURE BEING CONNECTED TO SAID PERFORATION BY A CHANNEL LEADING FROM SAID SECOND APERTURE TO SAID PERFORATION AND WHEREIN SAID APERTURES CONNECT SAID FIRST SURFACE TO SAID SECOND SURFACE; A SECOND METALLIC MEMBER DESIGNED TO CONTACT ALL POINTS ON SAID FIRST SURFACE WHICH ARE LOCATED ALONG THE PERIPHERY OF SAID APERTURES WHEN PLACED IN JUXTAPOSITION TO SAID FIRST MEMBER ALONG SAID FIRST SURFACE; A THIRD METALLIC MEMBER DESIGNED TO CONTACT ALL POINTS ON SAID SECOND SURFACE OF SAID FIRST MEMBER WHICH ARE LOCATED ALONG THE PERIPHERY OF SAID APERTURES WHEN PLACED IN JUXTAPOSITION TO SAID FIRST MEMBER ALONG SAID SECOND SURFACE; AND A CORE MATERIAL WHICH IS STABLE AT THE BONDING TEMPERATURE OF SAID MEMBERS; (2) PLACING SAID CORE MATERIAL IN SAID FIRST APERTURE, PLACING SAID SECOND MEMBER IN JUXTAPOSITION TO SAID FIRST MEMBER ALONG SAID FIRST SURFACE, AND PLACING SAID THIRD MEMBER IN JUXTAPOSITION TO SAID FIRST MEMBER ALONG SAID SECOND SURFACE, SAID SECOND MEMBER AND SAID THIRD MEMBER BEING PLACED SO AS TO COMPLETELY ENCLOSE SAID FIRST APERTURE AND SAID SECOND APERTURE; (3) SEALING SAID SECOND MEMBER AND SAID THIRD MEMBER TO SAID FIRST MEMBER ALONG THE OUTER EDGES OF THE AREA OF CONTACT OF SAID SECOND MEMBER AND SAID THIRD MEMBER WITH SAID FIRST MEMBER TO FORM AN ASSEMBLED STRUCTURE; (4) HEATING SAID ASSEMBLED ARTICLE TO A TEMPERATURE SUFFICIENT FOR BONDING OF SAID MEMBERS; AND (5) APPLYING PRESSURE TO SAID HEATED ASSEMBLED ARTICLE IN A DIRECTION NORMAL TO A PLANE PASSING THROUGH SAID FIRST MEMBER AND EQUIDISTANT FROM SAID FIRST AND SAID SECOND SURFACES, SAID PRESSURE BEING FIRST APPLIED ALONG POINTS AT THE OUTER EDGE OF SAID STRUCTURE ADJACENT A BOUNDARY LINE OF SAID FIRST APERTURE WHICH IS FURTHEST REMOVED FROM SAID SECOND APERTURE, SAID POINTS OF PRESSURE BEING PROGRESSIVELY MOVED ALONG THE SURFACE OF SAID STRUCTURE IN THE DIRECTION OF SAID SECOND APERTURE UNTIL THE ENTIRE STRUCTURE HAS BEEN SUBJECTED TO SAID PRESSURE.

Claim 2

A METHOD OF MANUFACTURING AN ARTICLE CONSISTING OF A CORE MATERIAL COMPLETELY ENCASED IN A METALLIC SUBSTANCE COMPRISING (1) PROVIDING A FIRST METALLIC MEMBER HAVING AT LEAST A FIRST SURFACE, A SECOND SURFACE, AND A THIRD SURFACE AND CONTAINING A FIRST APERTURE IN A FIRST PORTION OF SAID MEMBER, A SECOND APERTURE IN A SECOND PORTION OF SAID MEMBER, AND A PERFORATION LOCATED IN ITS THIRD SURFACE, SAID SECOND APERTURE BEING CONNECTED TO SAID PERFORATION BY A CHANNEL LEADING FROM SAID SECOND APERTURE TO SAID PERFORATION AND WHEREIN SAID APERTURES CONNECT SAID FIRST SURFACE TO SAID SECOND SURFACE; A SECOND METALLIC MEMBER DESIGNED TO CONTACT ALL POINTS ON SAID FIRST SURFACE WHICH ARE LOCATED ALONG THE PERIPHERY OF SAID APERTURES WHEN PLACED IN JUXTAPOSITION TO SAID FIRST MEMBER ALONG SAID FIRST SURFACE; A THIRD METALLIC MEMBER DESIGNED TO CONTACT ALL POINTS ON SAID SECOND SURFACE OF SAID FIRST MEMBER WHICH ARE LOCATED ALONG THE PERIPHERY OF SAID APERTURES WHEN PLACED IN JUXTAPOSITION TO SAID FIRST MEMBER ALONG SAID SECOND SURFACE; AND A CORE MATERIAL WHICH IS STABLE AT THE BONDING TEMPERATURE OF SAID MEMBERS; (2) PLACING SAID CORE MATERIAL IN SAID FIRST APERTURE, PLACING SAID SECOND MEMBER IN JUXTAPOSITION TO SAID FIRST MEMBER ALONG SAID FIRST SURFACE, AND PLACING SAID THIRD MEMBER IN JUXTAPOSITION TO SAID FIRST MEMBER ALONG SAID SECOND SURFACE, SAID SECOND MEMBER AND SAID THIRD MEMBER BEING PLACED SO AS TO COMPLETELY ENCLOSE SAID FIRST APERTURE AND SAID SECOND APERTURE; (3) SEALING SAID SECOND MEMBER AND SAID THIRD MEMBER TO SAID FIRST MEMBER ALONG THE OUTER EDGES OF THE AREA OF CONTACT OF SAID SECOND MEMBER AND SAID THIRD MEMBER WITH SAID FIRST MEMBER TO FORM AN ASSEMBLED STRUCTURE; (4) HEATING SAID ASSEMBLED ARTICLE TO A TEMPERATURE SUFFICIENT FOR BONDING OF SAID MEMBERS; AND (5) APPLYING PRESSURE TO SAID HEATED ASSEMBLED ARTICLE IN A DIRECTION NORMAL TO A PLANE PASSING THROUGH SAID FIRST MEMBER AND EQUIDISTANT FROM SAID FIRST AND SAID SECOND SURFACES, SAID PRESSURE BEING FIRST APPLIED ALONG POINTS AT THE OUTER EDGE OF SAID STRUCTURE ADJACENT A BOUNDARY LINE OF SAID FIRST APERTURE WHICH IS FURTHEST REMOVED FROM SAID SECOND APERTURE, SAID POINTS OF PRESSURE BEING PROGRESSIVELY MOVED ALONG THE SURFACE OF SAID STRUCTURE IN THE DIRECTION OF SAID SECOND APERTURE UNTIL THE ENTIRE STRUCTURE HAS BEEN SUBJECTED TO SAID PRESSURE.
