Abstract

365,813. Aerials ; electric cables. FAIRWEATHER, W. C., 65, Chancery Lane, London.-(Luckhardt Ges., L. ; 87, Leipzigerstrasse, Bettenhausen, Cassel, Germany.) Feb. 3, 1931, No. 3405. [Class 40 (v).] To protect a wireless receiver l from interference due to local sources of induction or radiation, the aerial down-lead consists of a core a, Fig. 2, of the same cross-section as the aerial d, Fig. 1, covered by a thick insulating sheath b, surrounded in turn by a metal screen or covering c. The covering c may be a tube, or may be formed by a wrapping of metal tape, or may consist of metallic dust mixed with a cement. Porcelain tubes m, n may be threaded on the ends of the down-lead where the screen c is cut away. A clamp o is connected to the supporting rope, whilst clamps p, q connect the screen c to earthing-wires s, t respectively. The wire s is connected to the earthing-wire v of a lightning-arrester i.
