Abstract

153,231. Batty, D. E., Whyte, S., and Associated Equipment Co. April 28, 1919. Moulds; treating after electrolysis; copper, depositing.-Capillary tubes are made by electrodeposition of a metal on a core which is afterwards forcibly removed. The core may be tin or like wire, which is melted and blown out from the deposit. Alternatively, a graphited thread, which may first have been waxed, or a steel or other refractory wire, preferably lubricated with graphite, may be used. A copper cyanide or sulphate electrolyte may be employed throughout, or the two solutions may be used successively. With the cyanide, solution, and a tin wire, a current density of 12-15 amperes per sq. ft. is suitable. The copper tubes obtained may be 17-21 mm. long and of about 0.017 in. bore.
