Abstract
129,059. Rota, L. G. V. May 28, 1918. Signalling proximity of vessels, iecbergs, and the like.-Apparatus for detecting the proximity of mines, submarines, icebergs, &c. comprises a. wooden cylinder d carried by spokes d<1> and bearings d<2> on a shaft d<3> fixed within an outer wooden cylinder a. The cylinder d has insulated windings d<4> connected through brush and ring contacts d<5> with a sensitive galvanometer f<2>, and may be rotated by a flexible shaft e<2> and bevelgear e<1>. A fixed frame g with coils of soft-iron wire g<1> or plates has within it a magnetic declination needle g<2>. An outer iron casing a<1> with pointed ends may be provided, and the apparatus is suspended from a ship by a telescopic shaft b<3> with ball bearings b<2>, c, or by other suitable suspension, allowing the axis of the device to be kept horizontal, and its height and position about a vertical axis adjusted. The needle is observed by reflexion in mirrors h, h<1>, and the galvanometer directly, through a tube i which may be provided with lenses, a lamp a<4> serving for illumination. The device may be used with the cylinder d stationary and its axis at right-angles to the magneto meridian, or with the cylinder rotated and its axis parallel to the meridian or inclined thereto at 30 to 35 degrees. The apparatus is stated to indicate the proximity and direction of a mine &c, Two such devices may be used in conjunction, with the cylinders respectively stationary and rotating, and one of the devices may have a dip needle. In a modification, stated to detect the proximity of an iceberg owing to its high electric potential, the casing a is omitted, and two copper cylinders are provided, one within and the other without the cylinder a, extending approximately half its length and carried by a disk which closes the end of the cylinder d. The copper cylinders are connected to an electroscope or torsion balance.
