Abstract: 1,057,519. Electrical geophysical prospecting. RAND MINES Ltd. Dec. 13, 1965, No. 52888/65. Heading G1N. In a method of detecting subterranean discontinuities, bore-holes 1 and 2, Fig. 1 are provided, down which, are hung coaxial cables 3 and 4, having bored centre-conductor ends to act as receiving and transmitting antennae respectively. The radiated frequencies are chosen in the range 50 to 5000 Kc/s, such that with the spacing used between the antennae, transmission is by means of the inductive field. If the antennae are lowered down the bore holes at equal depths D, the strength of the received signal, using constant transmitted strength varies according to C log 10 D, Fig. 3 (not shown). The interruption of the transmission path by a discontinuity, e.g. fissure, cavity or conducting body, causes a departure from this law, the extent of which gives the vertical extent of the discontinuity. Having established the position and extent of the discontinuity in the vertical plane, the antenna are again moved along the bore holes but at different depths, keeping transmission path length CD constant. This provides a cross bearing of the discontinuity, allowing its position to be determined. Alternatively a horizontal pattern of boreholes may be dug, Fig. 2, (not shown). The position of the discontinuity being determined by cross bearings between two pairs of bore holes.

The piston 3 is preferably retracted by interrupting the supply of pressure medium on line 13 whereupon the auxiliary piston 11 is forced to rise and carry with it piston 3. The relative position between an extension rod 17 carried by control piston 3 and the cylinder 4, fixed with respect to the lower surface of the material 24, 25, is thus a measure of the material thickness. This relative thickness is preferably detected by an armature 18 moving in a coil assembly 15. If the sheet material is a composite of an insulating layer 24 on a metal backing 25, an additional coil 23 can be fixed to the nozzle 1 to measure the thickness of the metal 25 and hence by subtraction the thickness of the insulating layer 24. In an alternative embodiment Fig.2 (not shown) an amplifier cylinder (32) and piston (36) arrangement is interposed between the control piston 3 and the nozzle 1.

A method of detecting fault conditions in an alternating current circuit through which direct current may be passed comprises the steps of connecting the circuit to a D.C. supply and detecting when the direct current flowing in the circuit lies outside predetermined limits, indicating the presence of a fault in the circuit. A tachogenerator winding W1 and a transformer winding W2 connected to processing circuitry are connected in series with a resistance R1 between a voltage source E<SP>+</SP> and a point OU of zero voltage, and under normal operating conditions the base bias on transistors VT1 and VT2 connected together in the long tailed pair configuration are such that VT1 carries substantially all of the long tailed pair current and the output from a transformer TR is a train of pulses where frequency is determined by that of a switching signal fed to a transistor VT3 in the common emitter line of VT1 and VT2. Under short circuit conditions in the winding W1 the base bias of transistor VT1 falls below that of transistor VT2 so that the latter carries substantially all of the long tailed pair current and there is zero output from the transformer TR. Under open circuit conditions in winding W1 the potential across a capacitor C1 rises to a value determined by the breakdown voltage of a Zener diode D1 and the base-emitter voltage of VT1, and under these conditions transistors VT1 and VT2 are independent of the switching transistor VT3 and the current in the transformer TR is a constant direct current. The circuitry is said to be of use in testing transformers and A. C. motors.
