Abstract

1362593 Preventing corrosion of boats ENGELHARD MINERALS & CHEMICALS CORP 15 Nov 1971 [17 Nov 1970] 52994/71 Heading C7E An electric supply from shore to a boat through leads 6, 7 has a ground lead 8 connected to the hull of the boat through a filter having pairs of rectifiers 12, 13 and 14, 15 and a non- polar capacitor or as shown a pair of polarized electrolytic capacitors 16, 17, to provide a low impedance path to a fault current and a high impedance path to a low voltage D.C. inherent in the corrosion of the hull.
