Abstract: A fast response ceramic ignitor which is particularly adapted for use with household current as a replacement for gas pilot lights, the ignitor being formed from pure lanthanum chromite, or lanthanum chromite which has been doped with combinations of niobium, magnesium, or strontium ions in quantities sufficient to provide desired electrical resistivity characteristics.

Abstract: A traffic channeling device for positioning on a highway in a normal traffic flow pattern. The channeling device comprises generally a paperboard shell structure which has formed on its lower portion, a plurality of flaps which are utilized in combination with holding means to hold the shell structure in a pre-determined position on the highway. The holding means may comprise a weight being positioned within the shell and in the preferred embodiment the weight may comprise at least one and preferably a plurality of automobile tires being positioned within the shell and on top of the flaps. The paperboard shell also has positioned on the outside thereof warning means for warning the traffic flow that the device has been positioned on the highway in the normal traffic flow with the warning means comprising an adhesive reflecting tape applied to at least a portion of the outside of said shell and preferably to the entire outside shell.

Abstract: A method of decreasing the electrical resistivity of a rare-earth chromite material by substituting bivalent metal ions for some of the chromium or rare-earth ions therein. The method includes applying a solution containing the bivalent metal ions to the rare-earth chromite under vacuum conditions, drying the solution on the chromite, and diffusing the bivalent metal ion into the rare-earth chromite by firing the chromite in a controlled atmosphere.
