Magnetostrictive core production

Claim 1

THE METHOD OF PRODUCING A MAGNETOSTRICTIVE CORE WHICH COMPRISES HEAT TREATING A STRIP OF MAGNETOSTRICTIVE METAL FOR ITS INTENDED ULTIMATE USE, COATING THE HEAT TREATED STRIP WITH AN ADHERENT ELECTRICAL INSULATING MATERIAL, WINDING THE COATED STRIP INTO A SCROLL AROUND A FORM WITH A TEMPORARY RIBBON-LIKE INTERLAY TAPE ACTING AS A SPACER BETWEEN ADJACENT TURNS OF THE SCROLL, SUBMERGING THE SCROLL AND FORM IN A RESIN BATH IN A CLOSED CHAMBER, HEATING THE SUBMERGED SCROLL AND RESIN, TO ABOUT 160* F. WHILE LOWERING THE ATMOSPHERIC PRESSURE IN SAID CHAMBER FOR A PERIOD OF TIME ADEQUATE TO FACILITATE SUBSTANTIAL PENETRATION OF THE RESIN INTO THE SPACES BETWEEN ADJACENT TURNS OF THE SCROLL AND REMOVE ANY VOLATILE PRODUCTS INHERENT IN THE RESIN, THEN PHYSICALLY REMOVING THE INTERLAY AS A UNIT FROM BETWEEN THE LAYERS OF THE SCROLL, CONTINUING HEATING OF THE SCROLL AND RESIN SO FREED OF THE INTERLAY TO ABOUT 160*F. UNDER LOWERED ATMOSPHERIC PRESSURE TO FACILITATE FURTHER PENETRATION OF THE RESIN WITH THE SPACE BETWEEN ADJACENT TURNS PREVIOUSLY OCCUPIED BY SAID INTERLAY, NEXT TIGHTENING THE SCROLL AROUND THE FORM AND SECURING IT IN THAT CONDITION, THEN CURING, AT ABOUT 160*F., THE SCROLL, WHILE IT IS BENEATH THE SURFACE OF THE RESIN TO PREVENT THE RESIN FROM OOZING OUT OF THE INTERSTICES, UNTIL THE RESIN BECOMES A RUBBER-LIKE SOLID, THEN REMOVING FROM THE SCROLL EXCESS RESIN THAT SERVES NO USEFUL PURPOSE, THEN CONTINUING THE CURING OF THE SCROLL WITH ADHERING RESIN AT ABOUT 200*F. FOR ABOUT 12 HOURS, AND THEN REMOVING THE FORM FROM THE SCROLL.
