Abstract

401,730. Cables. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London.-(Assignees of Strieby, M. E. ; 175, Sagamore Road, Maplewood, New Jersey, U.S.A.) May 19, 1932, No. 14247. Convention date, May 21, 1931. [Class 36.] A multi-conductor 79 for use in a multiplex high-frequency transmission system comprises a lead sheath 78 containing a number of coaxial conductors, each of which is composed of an outer cylinder and an inner wire spaced apart by spaced star-shaped insulators threaded on the inner conductor. Specifications 130,432 and 142,115, [both in Class 40 (v), Wireless signalling &c.], are referred to.
