Abstract: The present invention is a method of using a high speed cutting belt for cutting various aggregate and non-aggregate, natural stone and composite building materials with steel or non-steel reinforced materials. The cutting belt comprises a tensile member base, a plurality of cutting segments brazed with brass shim stock to anchors and crimped to the tensile member base, and molded in urethane to form a continuous, flexible belt, said belt having a 90.degree. "V" shaped bottom inner surface and a flat, outer top surface.

Abstract: A cathodically protected water heater which eliminates the need of a conventional anode rod. The water heater tank includes a cylindrical shell enclosed by upper and lower heads and a flue which is mounted within openings in the lower and upper heads. The outer surface of the flue as well as the upper surface of the lower head is coated with a metal anodic to steel, and the metal coating on the flue extends continuously from the lower head to a location above the upper head. The remainder of the inner surface of the heater is also coated with the anodic metal. The anodic metal is applied in a sufficient thickness at least at the junction of the lower end of the peripheral flange of the upper head and the shell to bridge and seal the crevice opening which typically exists between the free end of the upper head flange and the shell wall.

Abstract: A cathodically protected water heater which eliminates the need of a conventional anode rod. The water heater tank includes a cylindrical shell enclosed by upper and lower heads, and a gas burner is located beneath the lower head. The waste products of combustion are discharged upwardly through the tank via a flue which is mounted within openings in the lower and upper heads. The outer surface of the flue as well as the upper surface of the lower head is coated with a metal anodic to steel, and the metal coating on the flue extends continuously from the lower head to a location about the upper head. The inner surface of the shell and the upper head are coated with a corrosion resistant coating, such as glass or metal anodic to steel as well, and the upper edge of the flange in the upper head bordering the opening is welded directly through the metal coating to the flue while the outer periphery of the lower head is welded to the lower edge of the shell.
