Abstract: 245,805. Ambronn, R. Feb. 16, 1925, [Convention date]. Vibrations, indicating. - In known means for investigating and determining the geological conditions and mineral wealth of a particular location based on the utilization of the electromagnetic or electro-dynamic action of a vibrating body or electric coil in the field of an electric coil the receiving instrument. for the waves or undulations set up by the bursting of blast charges &c., comprises a rigid base plate 1, Fig. 1, and a pillar 2 from which is suspended a heavy mass 3 of magnetizable material. The mass 3 is preferably tubular shaped and is guided by leaf springs 5, 6 and surrounded by a coil 4 in circuit with a battery 7 and variable resistance 8. The alternating current produced by the mass 3 oscillating within the coil 4 and superposed upon the direct current is conveyed to a transformer 10 and transmitted to an electric recording instrument such as an oscillograph. The damping of the oscillations of the mass of the coil 4 may be increased in a well known manner by connecting resistances in parallel across the coil or parts thereof or as shown in Fig. 1 by provision of an inductance 11 and condenser 12. According to the present invention a soft iron mass 3<a> is provided for the purpose of concentrating the field and controlling the electromagnetic force of the oscillating system. The mass 3a is preferably a tubular member of soft iron inserted between the mass 3 and the coil 4 or arranged beneath the mass as shown in Fig. 3 the coil 4 being formed in two sections 4a, 4b. In this form strong direct currents may be necessary to produce the desired magnetic field. To avoid this difficulty the lines of force may be confined within a substantially closed iron body or yoke such as 13, Fig. 5, wherein is shown a modified form of apparatus enclosed in a watertight casing for immersion in the sea, ponds, or drill holes at any desired depth. The mass 3 is suspended between springs 23. 24 and guided by diaphragms 20.
