Abstract: The invention relates to a dish rack with a protective coating comprising an electrocoated layer and a polymer layer. The coating also includes a base corrosion-resistant layer on the metallic dish rack and a primer layer adjacent to the electrocoated layer to improve adhesion of the polymer layer. The aesthetically appealing exterior coating protects the dish rack from corrosion and from corrosion propagation.

Abstract: A combined voltage detector and electrical continuity checker in the form of a pencil having a needle capable of piercing electrical insulation, a pair of light emitting diodes for determining the polarity of the voltage, a third light emitting diode and associated circuitry to perform a continuity check, a flexible cable and chip which can be plugged into the pencil to perform either one of the tests in conjunction with the needle, and biasing arrangements for the light emitting diodes in order to lower their threshold of conduction.
