Abstract: A double arm peg board support hook includes a pivoting lock bar that establishes a detent locked condition across the free ends of the hook support arms to prevent inadvertent dislodgement of articles stored thereon.

Abstract: A tool rack organizer having a support assembly including rows of horizontal arms normally disposed in parallel spaced relation to a storage wall. The outer arms are pivotally connected to the support assembly for independent movement between a closed position and an open position. The arms are provided with a series of longitudinally spaced opening for attaching implement hooks to thereby hang customary tools, equipment and other implements. The organizer, with the compact rows of hooks, provides a compact rack arrangement for storing and accessing a multiplicity of tools in a minimum of wall space.

Abstract: A unitary thick film resistor structure includes a first thick film resistor element formed on one face of a substrate and a second thick film resistor element formed on the opposite face of the substrate. The resistor elements are of complementary, substantially equal and opposite temperature coefficient of resistance characteristics such that when the two elements are connected in parallel to form a unitary structure, the opposite temperature coefficient characteristics provide a stable, mutually compensated low net temperature coefficient of resistance, and exhibiting an immunity to subsequent baking operations incident to the provision of a sintered protective outer coating.
