Inductances; frequency, measuring.-A variable inductance for use more especially in measuring wave-lengths and tuning in wireless telegraphy comprises two coils, one rotatable within the other, and a switch for changing the connexions from series to parallel. If the two coils are of equal self-induction, the combined inductance in series is four times that in parallel and may be read on the same scale. The switch may be mounted on the axle of the movable coil, and by arranging the change of connexions at the halfturn, the whole range can be spread over a complete turn of the coil. To avoid discontinuity, the coils may be of unequal inductance. As shown in Fig. 2, the coils are wound over threaded cornerpieces D<2>, E<2> of the fixed and movable frames D, E respectively in a casing A. The frame E is mounted upon a stud C<1> and an axle C, with a milled head B<3> and dial-plate B. In a modification, four coils of equal inductance are wound in pairs, two on each frame, and an additional switch is provided for changing the connexions of the pairs, so as to obtain a third range of inductance. For measuring wave-lengths, the fixed and movable coils F, G, Fig. 7, are connected through a commutator to an oscillation circuit K, N, a battery M, and either a lamp L or buzzer O.
