Abstract: The present invention relates to a rare earth-containing, alkali silicate frit which may be applied to a metal substrate to provide a porcelain enamel coating which has good thermal stability, an acid resistance of A on the PEI scale and improved cleanability, wherein the frit contains, based on the total weight of the frit:______________________________________ Oxide Wt. % ______________________________________ R.sub.2 O 10-30 MgO 0-5 B.sub.2 O.sub.3 0-5 SiO.sub.2 45-60 TiO.sub.2 0-10 F 0.5-5 CoO 0-3 NiO 0-5 X 12-30 ______________________________________whereinR represents an alkali metal andX represents a rare earth oxide having an atomic number of 57-60, preferably cerium oxide.The present invention is also directed to porcelain enamel coatings, especially for appliances, prepared from this rare earth-containing, alkali silicate frit.

Abstract: A lamp assembly for a clothes dryer for illuminating the interior of the dryer drum. The lamp socket assembly includes a pivotable socket whereby the assembly may be serviced by first pivoting the socket so that the lightbulb installed in the socket extends into the dryer drum. Positive stop and detent means are provided for positively indicating the operating and service positions of the lamp assembly. Furthermore, a handle is provided to pivot the lamp socket and the handle interferes with the installation of a protective lens for the assembly when the lightbulb has not been fully retracted to the operating position. The bracket for mounting the lamp assembly is formed integrally with reflectors for reflecting the light from the lightbulb into the dryer drum.
