Method of adjusting the resistance of thermistor elements

Claim 1

THE METHOD OF ADJUSTING THE RESISTANCE OF A LENGTH OF THERMISTOR MATERIAL CONSISTING ESSENTIALLY OF A MIXTURE OF METALLIC OXIDES HAVING THERMISTOR CHARACTERISTICS, WHICH METHOD COMPRISES FORMING A CONTINUOUS LENGTH OR THERMISTOR MATERIAL OF SUBSTANTIALLY INIFORM CROSS-SECTIONAL AREA THROUGHOUT ITS LENGTH ON A PAIR OF ELECTRICALLY CONDUCTIVE WIRES EMBEDDED THEREIN, NOTCHING THE LENGTH OF THERMISTOR MATERIAL AT LENGTHWISE SPACED APART POINTS TO FROM A SERIES OF PARTIALLY CONNECTED BEAD-LIKE SECTIONS, DRYING THE BEAD-LIKE SECTION TO FIRMLY SECURE THE SAME ONTO THE WIRES, CONTINUOUSLY PASSING THE LENGTH OF BEADLIKE SECTIONS ON THE WIRE LENGTHWISE AT A CONSTANT RATE OF AT LEAST ABOUT ONE FOOT A MINUTE THROUGH A HEATED ZONE MAINTAINED AT A CONSISTENT TEMPERATURE OF A VALUE TO GIVE EACH BEAD-KILE SECTION A PREDETERMINED RESISTANCE VALUE, EACH BEAD-LIKE SECTION HEREBY BEING IN THE ZONE WHILE PASSING THERETHROUGH FOR AN EQUAL PREDETERMINED SUBSTANTIAL PERIOD OF TIME TO ADJUST TO SAME TO THE PREDETERMINED RESISTANCE VALUE, CONTINUOUSLY REMOVING THE LENGTH OF BEAD-LIKE SECTIONS ON THE WIRE FROM THE ZONE AFTER PASSING THERETHROUGH REMOVING CERTAIN OF THE BEAD-LIKE SECTIONS FROM THE WIRE AND PERMITTING OTHERS TO REMAIN SECURED THEREON, AND SEVERING THE WIRE TO PRODUCE AN INDIVIDUAL THERMISTOR ELEMENT HAVING TERMINAL WIRES EMBEDDED THEREIN, SAID METHOD BEING CHARACTERIZED THAT EACH THERMISTOR ELEMENT PRODUCED FROM THE SAME LENGTH OF THERMISTOR MATERIAL IS SUBJECTED TO INDENTICAL TEMPERATURE CONDITIONS DURING THE STEPS OF EXTRUDING, NOTCHING, DRYING, PASSING THOUGH THE HEATED ZONE AND FIBRICATION INTO AN INDIVIDUAL ELEMENT. WHEREBY AT LEAST 74% OF THERMISTOR ELEMENTS FORMED FROM THE SAME LENGTH OF THERMISTOR MATERIAL HAVING A RESISTANCE WHICH DOES NOT VERY MORE THAN =10% FROM THE AVERAGE RESISTANCE OF THE ELEMENTS PRODUCED FROM EACH LENGTH WHICH RESISTANCE IS UNALTERED AFTER REHEATING THE THERMISTOR ELEMENTS AND COOLING THE SAME TO A TEMPERATURE WITHIN THE RANGE OF ATMOSPHERIC TEMPERATURES.

Claim 2

THE METHOD OF ADJUSTING THE RESISTANCE OF A LENGTH OF THERMISTOR MATERIAL CONSISTING ESSENTIALLY OF A MIXTURE OF METALLIC OXIDES HAVING THERMISTOR CHARACTERISTICS, WHICH METHOD COMPRISES FORMING A CONTINUOUS LENGTH OR THERMISTOR MATERIAL OF SUBSTANTIALLY INIFORM CROSS-SECTIONAL AREA THROUGHOUT ITS LENGTH ON A PAIR OF ELECTRICALLY CONDUCTIVE WIRES EMBEDDED THEREIN, NOTCHING THE LENGTH OF THERMISTOR MATERIAL AT LENGTHWISE SPACED APART POINTS TO FROM A SERIES OF PARTIALLY CONNECTED BEAD-LIKE SECTIONS, DRYING THE BEAD-LIKE SECTION TO FIRMLY SECURE THE SAME ONTO THE WIRES, CONTINUOUSLY PASSING THE LENGTH OF BEADLIKE SECTIONS ON THE WIRE LENGTHWISE AT A CONSTANT RATE OF AT LEAST ABOUT ONE FOOT A MINUTE THROUGH A HEATED ZONE MAINTAINED AT A CONSISTENT TEMPERATURE OF A VALUE TO GIVE EACH BEAD-KILE SECTION A PREDETERMINED RESISTANCE VALUE, EACH BEAD-LIKE SECTION HEREBY BEING IN THE ZONE WHILE PASSING THERETHROUGH FOR AN EQUAL PREDETERMINED SUBSTANTIAL PERIOD OF TIME TO ADJUST TO SAME TO THE PREDETERMINED RESISTANCE VALUE, CONTINUOUSLY REMOVING THE LENGTH OF BEAD-LIKE SECTIONS ON THE WIRE FROM THE ZONE AFTER PASSING THERETHROUGH REMOVING CERTAIN OF THE BEAD-LIKE SECTIONS FROM THE WIRE AND PERMITTING OTHERS TO REMAIN SECURED THEREON, AND SEVERING THE WIRE TO PRODUCE AN INDIVIDUAL THERMISTOR ELEMENT HAVING TERMINAL WIRES EMBEDDED THEREIN, SAID METHOD BEING CHARACTERIZED THAT EACH THERMISTOR ELEMENT PRODUCED FROM THE SAME LENGTH OF THERMISTOR MATERIAL IS SUBJECTED TO INDENTICAL TEMPERATURE CONDITIONS DURING THE STEPS OF EXTRUDING, NOTCHING, DRYING, PASSING THOUGH THE HEATED ZONE AND FIBRICATION INTO AN INDIVIDUAL ELEMENT. WHEREBY AT LEAST 74% OF THERMISTOR ELEMENTS FORMED FROM THE SAME LENGTH OF THERMISTOR MATERIAL HAVING A RESISTANCE WHICH DOES NOT VERY MORE THAN =10% FROM THE AVERAGE RESISTANCE OF THE ELEMENTS PRODUCED FROM EACH LENGTH WHICH RESISTANCE IS UNALTERED AFTER REHEATING THE THERMISTOR ELEMENTS AND COOLING THE SAME TO A TEMPERATURE WITHIN THE RANGE OF ATMOSPHERIC TEMPERATURES.
