    摘要： Coatings are described to improve the performance of cathodic protection systems used in water heater tanks. Semi-permeable sparingly soluble films of silicates and other organic resins protect critical areas of sacrificial anodes from concentrated usage which could sever their tank connections, yet preserve the total amount of protection available. They reduce usage of these more active anode areas and return them to service after less active ones are used up, and when the corrosion rate of exposed metal in the tank has been reduced by prolonged service, thus further extending anode life. Other coatings reduce usage of the entire anode in high conductivity waters and in electric heaters where such protection is rapidly consumed by secondary chemical reactions or absorbed by electric heating elements. These coatings also prevent complete deactivation of the anode by oxides, and bacterial interactions which generate objectionable odors. They lessen contamination of tank water by insolubilizing anode byproducts, which are then electroplated onto nearby exposed steel to passivate it, further enhancing anode life. Coatings provide a "time released" protection by exposing fresh anode metal as they dissolve. They are applied either to the anode alone, or to both anode and exposed steel, or anode and electric heating element to increase their effectiveness. Such coatings also reduce anode usage by increasing its electrochemical efficiency which then allows less metal or lower cost alloys to be used for tank protection.

    摘要： The present invention relates to an electrical connector with at least one electrical contact for electrically contacting a corresponding mating connector. In particular, the present invention deals with connectors having a plug detecting unit for detecting a mated state of the connector and the mating connector. The present invention further relates to a corresponding method for detecting a mated state. Said connector comprises a plug detecting unit for detecting a mated state of the connector and the mating connector, wherein said plug detecting unit is operable to check the mated state by means of an intermittent test signal. Alternatively or additionally, the surfaces of first and second electrical contacts are covered with materials having a different oxidation potential, wherein a positive voltage of the test signal is applied to the electrical contact having the higher oxidation potential compared to the other electrical contact.

    摘要： Control of lead contamination in residential water supplies is accomplished by cathodic protection of lead-containing piping and lead-containing fixtures. Specifically, a partially insulated wire is inserted into lead-containing service lateral piping. Application of a DC current to the partially insulated wire causes the wire to act as an anode and transforms the walls of the pipe into the cathode, thereby protecting against corrosion. Alternatively, a sacrificial anode is inserted into a lead-containing fixture. The electrical potential generated by corrosion of this sacrificial anode transforms the walls of the fixture into a cathode, thereby preventing corrosion. Carbonate scaling built-up prior to the initiation of cathodic protection may be removed by temporarily blocking the water pipe and introducing cleaning chemicals.
