Abstract

299,298. MacDonald, J. Q., and Scott, W. M. Oct. 22, 1927, [Convention date]. Right to Patent relinquished. Chromium, depositing; metals, removing; electrolytes, circulating; electrodes.-A hollow body such as a rifle barrel 1 to be plated internally with chromium is sealed at the bottom and top by stoppers 3, 2 connected by pipes respectively to a supply tank containing chromic acid and an overflow return pipe. The anode consists of a rod or wire 4 accurately centred and tensioned by nuts 5; the anode is connected to the supply at both ends. A gas vent 13 is provided. The plating may be removed by reversal of the current.
