Obraztsy, Tovarnye Znaki 1984, (19), 91. (Russian). (Union of Soviet Socialist Republics). CODEN: URXXAF. CLASS: IC: C21D009-58. APPLICATION: SU 78-2695677 12 Dec 1978. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) The device contains 3 contact baths filled with current-conducting liqs. which are successively installed with respect to the path of the technol. process with the middle bath filled with a Pb melt. The device also contains a power supply. The quality of products is improved by a complete removal of Pb from the surface in the 1st bath with an electrolyte soln. and the 3rd one with salt peter [7757-79-1].
