C-shaped magnetizable core
Abstract
Abstract A C-SHAPED MAGNETIZALE CORE AND METHOD OF MAKING SAME OF POWDERED MATERIAL MANUFACTURED BY FILLING A PREDETERMINED QUANTITY OF THE POWERED MATERIAL INTO A C-SHAPED MOLD HAVING TWO ENDS AND HAVING A TRAPEZOIDAL CROSS SECTION, COMPRESSING SAID POWDERED MATERIAL TO A DENSITY OF AT LEAST 6.0 G./CM.3 BY A COOPERATING, C-SHAPED RAM FROM THE LARGER TRAPEZOIDAL BASE TOWARD THE SMALLER TRAPEZOIDAL BASE, WITHDRAWING THE RAM AND EJECTING THE CORE FROM THE DIE WITH A COMPARABLY C-SHAPED ROD FROM THE SMALLER TRAPEZOIDAL BASE TOWARD THE LARGER TRAPEZOIDAL BASE, THE CORE UNIFORMLY EXPANDING LATERALLY AS IT IS EJECTED FROM THE DIE HAVING A UNIFORM DENSITY OF IMPROVED STRUCTURAL, MAGNETIC AND ELECTRICAL PROPERTIES.
