Claim 3
Independent Claim
73 words
A METHOD OF MAKING A SHEET-LIKE POROUS METAL STRUCTURE COMPRISING EMBOSSING A SHEET METAL MEMBER TO FORM GROOVE-LIKE INDENTATIONS THEREIN PROTRUDING OUT OF ONE FACE OF SAID MEMBER, FILLING SAID INDENTATIONS WITH AN EVANESCENT MATERIAL, PROVIDING A LAYER OF METALLIC PARTICLES ON THE FACE OF SAID STRUCTURE OPPOSITE SAID ONE FACE, METALLURGICALLY BONDING BY SINTERING SAID PARTICLES TO EACH OTHER AND TO THE UNEMBOSSED PORTIONS OF SAID OPPOSITE FACE AND ELIMINATING SAID MATERIAL.
