Abstract: A vitreous enamel resistor material comprising a mixture of vitreous glass frit and fine particles of a mixture of zinc oxide (ZnO) and a material which will provide either lithium, tin, nickel, aluminum, indium, titanium, tantalum, zinc, gallium, vanadium, tungsten, or molybdenum. An electrical resistor is made from the resistor material by applying the material to a substrate and firing the coated substrate to a temperature at which the glass melts. Upon cooling, the substrate has on a surface thereof a film of glass having the particles of the mixture embedded therein and dispersed therethroughout. The resistor material provides a resistor having a wide range of resistivities with a low temperature coefficient of resistance and a low voltage coefficient of resistance.

Abstract: Polyolefin compounds containing nitrile polysiloxane fluid which have improved electrical properties, and electrical conductors insulated therewith.

Abstract: A modified clay paper coating composition comprising a montmorillonite clay having at least partially hydrolyzed aluminum chloride bonded thereto is made by treating montmorillonite clay with a non-aqueous solution of anhydrous aluminum chloride following by hydrolyzing with hot water. A paper substrate coated with this composition exhibits improved image light fastness when employed in a pressure-sensitive duplication system.
