Abstract
Abstract Information transmitting systems including a plurality of tubular members for pneumatically or hydraulically passing data in pulse form; the tubular members being stranded about a core member which may be tubular or in electric cable form, the tubular members being stranded with a reverse lay to allow such members to be displaced to allow convenient tapping of the tubular members or the core member.
