Method of mass producing resistors

Claim 1

A METHOD OF MASS PRODUCING RESISTORS COMPRISING, FORMING REVERSE BENDS ON A CONTINUOUS RESISTANCE WIRE THEREBY DEFINING LOOPS ARRANGED IN SUCCESSIVE GROUPS EACH HAVING A GIVEN NUMBER OF LOOPS AND DISPOSED LONGITUDINALLY SPACED IN AN ELONGATED CONFIGURATION, DISPOSING BETWEEN SUCCESSIVE INDIVIDUAL GROUPS OF LOOPS TWO LONGITUDINALLY SPACED CAVITY-FORMING FUGITIVE ELEMENTS EXTENDING AXIALLY TRANSVERSELY OF THE LONGITUDINAL DIRECTION OF SAID ELONGATED CONFIGURATION AT POSITIONS DESIGNATED AS END PORTIONS OF EACH TWO NEXT ADJACENT ONES OF SAID SUCCESSIVE GROUPS, SAID CAVITY-FORMING ELEMENTS EACH BEING DISPOSED IN POSITION TO BE COVERED AXIALLY ONLY PARTIALLY WITH CERAMIC PASTE FOR FORMING AN ELONGATED CERAMIC-COVERED BAND CONFINING SAID LOOPS, AND WHILE EMBEDDING SAID RESISTANCE WIRE AT THE SAME TIME EMBEDDING SAID CAVITY-FORMING ELEMENTS IN SAID CERAMIC PASTE ONLY PARTIALLY AXIALLY THEREBY TO ALLOW AT LEAST AN END SURFACE OF EACH OF SAID CAVITY-FORMING ELEMENTS TO BE DISPOSED OUTWARDLY OF SAID BAND, SEVERING SAID CERAMIC COVERED BAND INCLUDING THE SEVERING OF SAID WIRE BETWEEN THE SUCCESSIVE GROUPS AND SAID CAVITY FORMING ELEMENTS TO FORM A PLURALITY OF RESISTORS, AND FIRING THE INDIVIDUAL RESISTORS AT A TEMPERATURE INSUFFICIENT TO DAMAGE SAID WIRE AND SUFFICIENT TO COMPLETELY SET THE CERAMIC, CAUSING SAID CAIVITYFORMING ELEMENTS TO EMIGRATE FROM SAID RESISTORS THEREBY TO DEFINE ACESS CAVITIES OPEN TO THE EXTERIOR OF SAID CERAMIC AXIAL TO THE OPPOSITE END PORTIONS OF SAID RESISTANCE WIRE WITHIN EACH RESISTOR, AND CONNECTING LEADS TO SAID RESISTANCE WIRE EXTENDING THROUGH SAID CAVITIES IN SAID RESISTORS.

Claim 2

A METHOD OF MASS PRODUCING RESISTORS COMPRISING, FORMING REVERSE BENDS ON A CONTINUOUS RESISTANCE WIRE THEREBY DEFINING LOOPS ARRANGED IN SUCCESSIVE GROUPS EACH HAVING A GIVEN NUMBER OF LOOPS AND DISPOSED LONGITUDINALLY SPACED IN AN ELONGATED CONFIGURATION, DISPOSING BETWEEN SUCCESSIVE INDIVIDUAL GROUPS OF LOOPS TWO LONGITUDINALLY SPACED CAVITY-FORMING FUGITIVE ELEMENTS EXTENDING AXIALLY TRANSVERSELY OF THE LONGITUDINAL DIRECTION OF SAID ELONGATED CONFIGURATION AT POSITIONS DESIGNATED AS END PORTIONS OF EACH TWO NEXT ADJACENT ONES OF SAID SUCCESSIVE GROUPS, SAID CAVITY-FORMING ELEMENTS EACH BEING DISPOSED IN POSITION TO BE COVERED AXIALLY ONLY PARTIALLY WITH CERAMIC PASTE FOR FORMING AN ELONGATED CERAMIC-COVERED BAND CONFINING SAID LOOPS, AND WHILE EMBEDDING SAID RESISTANCE WIRE AT THE SAME TIME EMBEDDING SAID CAVITY-FORMING ELEMENTS IN SAID CERAMIC PASTE ONLY PARTIALLY AXIALLY THEREBY TO ALLOW AT LEAST AN END SURFACE OF EACH OF SAID CAVITY-FORMING ELEMENTS TO BE DISPOSED OUTWARDLY OF SAID BAND, SEVERING SAID CERAMIC COVERED BAND INCLUDING THE SEVERING OF SAID WIRE BETWEEN THE SUCCESSIVE GROUPS AND SAID CAVITY FORMING ELEMENTS TO FORM A PLURALITY OF RESISTORS, AND FIRING THE INDIVIDUAL RESISTORS AT A TEMPERATURE INSUFFICIENT TO DAMAGE SAID WIRE AND SUFFICIENT TO COMPLETELY SET THE CERAMIC, CAUSING SAID CAIVITYFORMING ELEMENTS TO EMIGRATE FROM SAID RESISTORS THEREBY TO DEFINE ACESS CAVITIES OPEN TO THE EXTERIOR OF SAID CERAMIC AXIAL TO THE OPPOSITE END PORTIONS OF SAID RESISTANCE WIRE WITHIN EACH RESISTOR, AND CONNECTING LEADS TO SAID RESISTANCE WIRE EXTENDING THROUGH SAID CAVITIES IN SAID RESISTORS.
