  • Sacrificial anode with resistor assembly for metal tank corrosion protection
    Patent number: 7857949
    Abstract: A sacrificial metal anode device incorporating a resistor assembly into the construction of the sacrificial anode is insertable into a metal water storage tank. The metal water storage tank designed to contain heated water is thereby protected from corrosion by the sacrificial metal anode. The sacrificial metal anode device comprising an elongated metal anode member with a metal wire core, an insulating sleeve secured over the elongated metal anode member wherein said insulating sleeve has an external wall with threads to fixedly secure a metal cap. The metal cap having threads on an internal wall to fixedly secure the insulating sleeve further including a cylindrical receptacle for receipt of an end of the elongated metal anode member and an electrical resistor assembly.
    Type: Grant

  • Magnesium-calcium alloys for debismuthizing lead
    Patent number: 5143693
    Abstract: A novel alloy for use in lead refining is disclosed comprised substantially of magnesium and calcium. The preferred ratio on a weight basis of magnesium to calcium is between about 1.2:1 to about 3.0:1. A method of refining a lead bath with the novel alloy is disclosed which provides a high recovery ratio of impurities present therein.
    Type: Grant
