Abstract
117,507. Greenwood. J. W., and Hackett, E. H. July 26, 1917. Locating conductors. -Induction apparatus for detecting the presence of metals in wounds or in any non- metallic substance comprises a primary circuit containing a battery 2, an interrupter 3, a regulating coil 6, and a coil a wound on the same bobbin as a coil b in the secondary circuit which contains also a telephone receiver 23 and a coil 5 co-acting with the coil 6. The coils a, b are mounted within a surfacesearcher or a probe. The whole of the parts are contained in a box 1, Fig. 1, but in use a loose box 4 containing or supporting the regulating-coils 5, 6 together with switches and connexions is mounted on the lid of the box 1, electric connexions being made through plugs 9. A surface searcher 20 containing the coils a, b is detachably connected to the apparatus by a flexible connexion 19, and is formed with an opening 30 for a pencil to mark the location of the metal when found. The searcher 20 may be replaced by a probe 24 containing smaller coils, and in this case part of the windings of the coil 5 are cut out by means of a switch 7 so as to restore the balance. Before use, balance is perfected by adjustment of the coil 6 with reference to the coil 5 by means of a screw spindle 15 and a pointer 16. A condenser 31 is inserted in the primary circuit and in some cases a second condenser, (not shown), may. also be employed in the circuit f, g, e, Fig. 5. The interrupter 3 is mounted on short lengths 28 of india rubber tubing within a small silencing case 4, and is provided with a tongue flexible on both sides of the armature. The receiver 23 may be of the type described in Specification 22887/14, [Class 40 (iv), Telephones &c.]. In a modification the parts may be mounted within a small celluloid case to which a probe searcher is permanently connected. In this form the switch 7 is omitted and the case containing the regulating- coils serve as a surface searcher. The battery 2 may be replaced by a motor generator or other transformer supplied from an ordinary lighting circuit. The instrument may be employed to distinguish magnetic from non-magnetic metals according to the nature of the sounds generated in the receiver 23. According to the Provisional Specification, the regulating-coils may be adjusted by lateral or angular movement
