Abstract

908,310. Anodes for preventing corrosion. MAGNETO-CHEMIE N.V., and LABORATORIUM BEER N.V. Sept. 27, 1960 [Sept. 30, 1959], No. 33198/60. Class 123 (1). A sacrificial anode for protecting e.g. ships' hulls boilers, water coolant sys tems of I.C. engines &c., from corrosion comprises a magnet 1 which is coated with anodic material 2, e.g zinc, aluminium, or mag nesium, except for its polepieces 3 which are left uncovered to facilitate adhering to, and providing electrical contact with, the iron of the object to be protected. The anodic coating 2 has a terminal 4 which can be used to connect the anodic material to the wall of the object when the latter has an insulating layer, e.g. of enamel. If the object to be protected is not made of iron an iron armature is provided on the other side of the wall of the object to close the magnetic flux circuit. In a modification a cylinder of anodic material, having a contact terminal, is accommodated in a jar magnet provided with a transverse slot. In a further modification, one or more horse-shoe magnets are imbedded, with their poles projecting from, a block of anodic material provided with a contact terminal. The magnets may each enclose, and be movable in, a hollow space in the block to facilitate securement to an object. The boundary between the clad and the unclad portion of the magnet is preferably covered with insulation material.
