Abstract: A modular pulley assembly for a continuous belt conveyor can be assembly from a plurality of modular pulley disks that can be axially aligned and abut against each other to provide pulleys of differing lengths per demand. The modular pulley disks can be made from a non-metallic material such as a polymer and can manufactured by a suitable molding process. Making the modular pulley disks from non-metallic materials enables the disks to be formed with structural geometries such that the assembled pulley is structurally more rigid and can better distribute torsional loads and momentum from the belt to the support shaft.

Abstract: A method includes providing a conductor with a joint and a solution. In accordance with a step of the method, the conductor with the joint is inserted into the solution for a time sufficient to deposit a sufficient amount of conductive material in the joint to allow current to flow through the joint at a desired level when the conductor is installed in an application. In accordance with another aspect of the method, a structure with a joint is inserted into the solution for a time sufficient to deposit a sufficient amount of conductive material in the joint to strengthen the joint to a desired level. In accordance with another step of the method, an electromotive force is applied between an anode and the conductor for electolytic formation of the joint. In another aspect of the invention, the solution is configured for electroless formation of the joint.
