Abstract: AN IMPROVED RESISTOR COMPOSITION FOR USE IN RESISTOR SPARK PLUGS AND OTHER ELECTRICAL DEVICES IS DISCLOSED. THE RESISTOR COMPOSITION CONTAINS A COMPOUND TAKEN FROM THE GROUP CONSISTING OF LITHIUM CARBONATE, ZINC CARBONATE, MAGNESIUM CABONATE AND SODIUM CARBONATE AND A METAL POWDER TAKENFROM THE GROUP CONSISTING OF ZINC, ANTIMONY AND TELLURIUM IN ADDITION TO THE CONVENTIONAL RESISTOR COMPOSITION INGREDIENTS. THE CARBONATE, FOR EXAMPLE, LITHIUM

CARBONATE, AND THE METAL, FOR EXAMPLE, ZINC, COMBINE TO YIELD A STRONG RESISTOR MASS HAVING A LOW POROSITY WHICH BONDS TIGHTLY TO THE CENTER ELECTRODE HEAD IN THE SPARK PLUG INSULATOR CENTERBORE.

Abstract: THIS INVENTION RELATES TO AN IMPROVEDCERAMIC-TO-METAL CONDUCTIVE GLASS SEAL FOR CERAMIC INSULATORS AND MORE PARTICULARLY TO COMPOSITIONS COMRISING GLASS, IRON, COPPER, AND ALUMINIUM WHICH ARE SUITED FOR USE IN THE CENTERBORE OF SPARK PLUGS. THE IMPROVED SEAL OF OUR INVENTION COMPRISES A MIXTURE ON A WEIGHT BASIS OF ABOUT 50-65 PARTS IRON, 1-4 PARTS COPPER, 3-5 PARTS ALUMINUM, AND 30-45 PARTS GLASS; A PREFERRED EMBODIMENT COMPRISES ABOUT 56 PARTS IRON, 2 PARTS COPPER, 3 PARTS ALUMINUM,

AND 39 PARTS GLASS. THE ADDITION OF A FILLER MATERIAL SUCH AS MULLITE ENABLES THE BROADENING OF THE RANGE OF OUR COMPOSITION TO ABOUT 35-55 PARTS IRON, 1-4 PARTS COPPER, 3-5 PARTS ALUMINUM AND 30-50 PARTS GLASS, THE FILLER BEING PRESENT IN AN AMOUNT OF ABOUT 5-15 PARTS; A PREFERRED EMBODIMENT COMPRISES ABOUT 45 PARTS IRON, 2 PARTS COPPER, 3 PARTS ALUMINUM, 40 PARTS GLASS AND 10 PARTS MULLITE.
