Abstract: The flat wire conveyor belt comprises multiple part connecting rods used to incrementally extend the length of the flat wire conveyor belt and provide ease of repair and installation. The flat wire conveyor belt comprises U-shaped connecting rods. The multiple part connecting rods can be connected in a series of two or more to span the width of the flat conveyor belt. The flat wire connecting rods can connect to the picket, to each other, or via and intermediate connecting rod. The flat wire conveyor belt provides strengthened edges.

Abstract: A cathode for a discharge lamp comprises a longitudinally extending central core of a high temperature, electrically conductive metal; and a coil of high temperature, electrically conductive metal wound thereabout, said coil being fastened to said core at least in part by mechanical interference. The mechanical interference can be achieved by keyways formed in the core surface. During winding, at least some of the turns of the coil enter the keyways providing a good,mechanical engagement of the coil with the core. The keyways can be formed by heating the core and compressing or forging areas with tools or the keyways can be formed by grinding or by any other suitable means.
