SETT FOR FRAMSTELLNING AV KRAFTBUNDEN OCH ELEKTRISKT LEDANDE FORBINDELSE MELLAN KONCENTRISKA METALLROR

摘要

Two tube systems, each comprised of two or more concentrically arranged metal tubes, are positively and electrically conductive interconnected through a coupler sleeve system composed of a corresponding number of concentrically arranged coupler sleeves of slightly larger diameter such that ends of the sleeves of the coupler sleeves are threaded upon ends of the tubes of the tube systems to be interconnected.
