Title: Method of and means for determining distances by means of sound waves
IPC: G01S15/10
Filed: 1930-01-15
Abstract: 340,149. Siemens & Halske Akt.-Ges. Jan. 17, 1929, [Convention date]. Determining distances acoustically. - In a process for the determination of distances by the aid of sound waves, relays are successively operated by the variation of electric or magnetic fields, and the number of relays so operated in the time interval between the sending out of an impulse and its arrival or return is made recognisable. A sound reciver 2 is connected through an amplifier 3 and thermionic valves 4, 5, to the windings 6, 8 of a relay 7. The circuit is such that when a sound is emitted from the source 1 and impinges directly upon the receiver 2, the relay armature moves to close the contact 11, but when the weaker echo arrives, the armature closes the contact 10. Before a sound is emitted, the contact 10 is closed, a battery 12 then supplying current to three circuits; (a) one containing a relay 14 ; (b) one magnet 19 of a relay 15; and (c) the graduated retarded relays 13 - - 13<x>, the last circuit being through contacts 23, 26. Upon the sending of the sound, contact 10 is opened and contact 11 closed. The magnet winding 19 has a sufficiently great retarding effect to prevent the falling of the relay armature 15 until the latter is held by a winding 21 energized from a battery 22. The opening of contact 10 causes the de-energization of the relay 14 and of the retarded relays 13 - - 13x. These latter then open one after the other. The arrival of the echo opens contact 11 and closes contact 10, and, since relay 14 has a retarded action, the armature 15 falls to close contacts 18 and to light lamps 17 - - 17x in circuit with those relays which have not operated. The closing of relay 14 then lifts the armature 15 to close the contact 26 and to reset the relays 13 - - 13x, but the selected lamps remain lit by reason of the operation of retaining relays 24 - - 24<x> which establish circuits through lines 25 - - 25<x>. When the next determination is made, a relay 13 not previously released may be operated, and to extinguish the corresponding lamp a relay 27 is provided, connected across the relay 13. When the latter relay opens the relay 27 moves its armature to break the circuit 25. The current passing through the relays 27 is not sufficient to operate the retaining relays 24. The emitter 1 may operate every ten seconds, and the falling of the relays 13 may be recorded by the perforating of a paper strip. Instead of retarded relays, relays operating at different potentials may be used, the charging or discharging of a condenser during the time of travel of the sound wave causing the varying potential difference.
