Patent GB-297462-A (GB)
Abstract: 297,462. British Thomson-Houston Co., Ltd., (Assignees of Tear, J. de C.). Sept. 22, 1927, [Convention date]. Earth-inductor machines.-In an earth-inductor direction-finding apparatus for use in steering aircraft &c., the phase of the electromotive force generated in a coil rotating in the earth's field is compared with that of a standard electromotive force of the same frequency. In the construction shown in Fig. 1, the inductor coil 41 is driven by a direct-current motor 35 from a storage battery 36. One segment of the commutator 38 is connected to a slip-ring 37 on which bears a brush connected to one end of the primary winding 39 of a transformer. The other end of this winding is connected to an intermediate tap 40 on the battery 36. An alternating electromotive force is thereby impressed on the transformer winding 39. This electromotive force is of the same frequency as that induced in the inductor coil 41, its phase relation being dependent on the angular position of the brushes 42, 43, which are adjustably mounted. The inductor coil 41 is connected through an amplifier 46 to one winding of a phase-meter 47, the other winding of which is connected to the secondary winding 45 of the transformer. Two slip-rings 37 connected to diametrically opposite commutator segments may be provided to supply the alternating electromotive force to the winding 39. This electromotive force may alternatively be derived from the battery supplying the anode circuits of the amplifiers by means of a two-part commutator. The Specification as open to inspection under Sect. 91 (3 (a) comprises also the construction shown in Fig. 1 (Cancelled), an inductor coil is wound on an armature 10 of insulating material mounted on a vertical shaft 11. The ends of the inductor coil are connected to slip-rings 12, 13 between which an electromotive force is generated by rotation of the armature 10 in the earth's field by means of an electric motor 32, or a constantspeed air-driven propeller, or otherwise. Brushes bearing on the slip-rings 12, 13 are connected, through amplifiers 14, 15 and a transformer 16 to the movable coil 17 of a phase meter. Mounted on the shaft 11 is' a bar magnet 20, within the field of which are two armature coils 21, 22 connected in series with one another and, through amplifiers 27, 28 and a transformer 29, to the fixed coils 18, 19 of the phase meter. The coils 21, 22 are carried by an arm 23 adjustable about a vertical axis by means of a handle 24. Electromotive forces are generated in the coils 21, 22, by rotation of the magnet 20, of the same frequency as those generated in the inductor coil. The phase-meter indicates the phase-difference of the electromotive forces generated in the inductor coil and in the coils 21, 22, which is dependent upon the angle between the magnetic field of the earth and the axis of the coils 21, 22. Gimbal supports may be provided for the armature 10 so as to stabilize it in an horizontal plane. This subject-matter does not appear in the Specification as accepted.
