WIRELESS “SLEUTH”
FOR TRACKING DOWN OSCILLATORS TWENTIETH CENTURY WONDER (United Press Assn.—Copyright.) (Received Jan. 18, 7.20 p.m.) LONDON, Jan. 17. The latest addition to twentieth .century wonders is a van like an undersized Black Maria, with a circular frame aerial "on the roof. It is used as a post office sleuth in tracking down wireless oscillators. A hand on an innocent-looking dial inside the van is able to point with unerring certainty to ' the actual house in-'which the mysterious annoying oscillator resides, after which the officers enter and gentle persuasion and expert guidance follows. It is a truly ingenious system. Bearings are taken on three sides of the area visited, and plotted down on a large scale map. If the lines intersect eacii other, 1 the location of the oscillator is known, and the van proceeds immediately in tile indicated direction. As the house is approached the oscillations become gradually fainter till zero point is reached when the van gets immediately before the house.— A. and N.Z.O.A.
