Abstract: A sacrificial anode assembly operative to inhibit corrosion in the metal tank portion of a water heater includes a cylindrical metal anode member having an end retained within a tubular, electrically non-conductive plastic insulating sleeve which, in turn, is captives retained within a metal cap portion of the assembly. A resistor is received in an end surface groove of the sleeve and has a lead wire spot-welded or soldered to a core wire portion of the anode member. To prevent contact between the lead wire and the metal cap, and to protect the lead wire against vibration caused breakage at its spot weld or solder area, a U-shaped central portion of the lead wire is received in a through-opening in the resistor-supporting end of the sleeve which is covered by an annular insulating wafer formed from an electrically non-conductive material.

Abstract: The present invention provides a system for disinfecting shopping carts. In one embodiment, the system comprises a treatment station for applying a disinfectant to a shopping cart and a conveyor system for transporting carts relative to the treatment station at two different speeds so as to effect a nesting operation. In another embodiment, the system comprises a treatment station that is comprised of a first modular unit and a second modular unit that each perform different functions but can readily joined to one another to form a treatment station with the desired features for a particular application. In yet another embodiment, certain features of the modular units are symmetrical relative to a lateral plane to facilitate the joining of the units to one another in different orders. A further embodiment comprises a treatment station with a molded structure.
