Title: Improvements in or relating to the Detection of Submarine Impulses.

IPC: G01S1/72
Filed: 1917-10-09
Abstract: 129,311. Fessenden, R. A. March 29, 1917, [Convention date]. Subaqueous sound and like signals; locating subaqueous sound and like vibrations.-Consists in detecting the proximity of vessels, particularly submarines, by means of low-frequency impulses, of the order of one per second, emitted by them. The impulses received are transformed into electric vibrations and interpreted by a suitable device such as a galvanometer or telephone receiver. Arrangement may also be made whereby the direction of the source of the impulses may be estimated. Two electro-magnetic devices 12. 13, preferably oscillators of the type described in Specification 18765/13, are carried one at each side of a sound-insulating screen 14 mounted parallel with the longitudinal axis of an observing vessel 11. The screen may be of metal plates with an interposed layer of asbestos, and is pivotally hung from the rods 31 of pistons working in hydraulic, cylinders 15, 16, whereby the screen and oscillators may be housed within a recess 261 within the bottom of the vessel, or lowered for use. By lowering one piston more than the other, the screen and oscillators may be given a fore-and-aft tilt to estimate whether the detected vessel lies ahead or astern. The currents from the oscillators are taken to galvanometers 26, 27, which may be connected with condensers 38, 39 as shown, to eliminate the effects of the high-frequency water noises due to the ves. sel 11. These local noises may also be eliminated by using only one galvanometer and connecting the oscillators thereto in opposition. The direction of the detected vessel may be found by turning the vessel 11 until the indications of the galvanometers are in phase, or by inserting inductances and capacities in the galvanometer circuits in known manner to estimate the phasedifference. Instead of turning the vessel 11, the screen and oscillators may be arranged to rotate about a vertical axis. Instead of connecting the oscillators to the galvanometers directly, amplifying-devices such as the audion or plistron may be used; and it is stated that the amplified electric currents and voltages may be used to produce an indication of a larger intensity or of greater frequency as described in Specification 106,268, telephone receivers being used in place of galvano. meters.

P., 57, Broughton Avenue, Finchley, both in London. May 25, 1932, No. 14880. [Class 118 (ii).] A pressure wave transmitter and /or receiver suitable for use in echo sounding and subaqueous signalling systems and for detecting underwater bodies, such as icebergs, comprises a magneto-strictive body associated with a planar, conical or parabolic reflector in order to obtain directivity. The magnetostrictive body is preferably arranged in a horizontal position and both of its end faces used for radiation, two reflecting surfaces being utilised to give radiation substantially vertically downwards. Such a device may be arranged with the body lying transversely of the ship, the reflecting surfaces being positioned so as to give an angle of radiation such that even in a bad sea good echoes may be obtained despite rolling of the ship. Alternatively, the body may be arranged substantially in line with the ship so that, in the case of a fast ship, a returning echo would not be left behind. Directivity may also be obtained by the interference method, a plurality of small projectors P excited in phase being employed as shown in Fig. 7. The projectors are preferably connected through distance pieces to a common surface plate SP which vibrates bodily after the manner of a piston. The Provisional Specification describes a modification in which the lower half of the magnetostrictive body projects either from the ship's bottom or out level with the ship's bottom in a suitable chamber.
