Abstract

353,516. Preventing inductive disturbance. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Assignees of Affel, H. A. ; 827, Morningside Road, Ridgewood, and Green, E. I. ; 150, North Munn Avenue, East Orange, both in New Jersey, U.S.A.) April 25, 1930, No. 12835. Convention date, Oct. 2, 1929. Drawings to Specification. [Class 40 (iv).] In a carrier current signalling system to vehicles in which existing lines adjacent the track are utilized interference with adjacent telegraph and telephone lines is prevented by inserting in those lines not used for carrier signaling loading or choke coils. Specification 335,936, [Class 40 (v), Wireless signalling &c.], is referred to.
