Abstract

188,676. Ionides, A. G. Sept. 20, 1918. Signalling proximity of vessels.-Apparatus for detecting conducting bodies in an electrolyte, and especially for detecting the presence and position of submerged submarines, comprises a pair of immersed electrodes connected to a galvanometer which is ducted by a direct current given out by the submarine. As shown in Fig. 1, the two electrodes A, B, spaced apart, are towed by or attached to a searching vessel C carrying the galvanometer D, which is deflected when the electrodes pass over or near a submarine. If the submerged body does not give. sufficient current, the body may be charged after the manner of a secondary battery, by direct current sent cut by electrodes E, F which are also towed by the vessel C and are situated ahead and astern of the detecting-electrodes A, B as shown in Fig. 2. The charging-current supplied by the source G is interrupted at intervals, to enable the secondary current sent out by the submerged body to be detected. To prevent inductive effects owing to the towed cables cutting across the earth's magnetic field they are twinned between the vessel C and the nearer electrode A; and similar effects due to rolling of the vessel are neutralized by a compensating coil. The tow-cables may be of the same density as sea-water or may be buoyed or guided by planes fised to the cables. The detecting-electrodes A, B, may be of wire strands insulated by fibrous material which holds in place a de-polarizing reagent. They may be formed as discs at one end of insulating tubes, and may be surrounded, or covered by a layer of jelly. The charging-electrodes may comprise insulating rods with separated longitudinal flutings lined with metal. The apparatus shown in Fig. 1, may be duplicated, both sets being towed by the same vessel C, and separated transversely to the course by means of kites. The electrodes may be oonnected to separate galvanometers, or to a single differential galvanometer, which will then indicate on which side of the course the submarine is situated.
