1874 Lancet 28 Feb. 309/2 The apparatus is supplied with a collector, a galvanometer, invertor, &c.
1961 Listener 9 Nov. 773/1 The valve serves not only as a rectifier..but—at the other end of the direct current link—as an invertor, turning direct current into alternating current.
2009 S. W. Fardo & D. R. Patrick in Electr. Power Syst. Technol. (ed. 3) 190 A motor-driven generator unit..can be used to convert DC to AC. This system is called an invertor.
b. A device or apparatus used to periodically reverse the direction of an electric current; a commutator. Now rare.
ΚΠ
1889 Cent. Dict. Invertor, that which inverts or changes the direction, as of an electric current.
1974 Proc. Inst. Electr. Engineers 122 1142/2 For these two types of supply, it is necessary to define the maximum permissible value of flux density as a function of the characteristics of the machine and invertor or commutator.
2. Anatomy. Any muscle involved in inversion of the foot (see inversion n. 22); esp. the tibialis posterior or tibialis anterior (see tibialis adj.). Also invertor muscle.

1875 Lancet 9 Oct. 517/1 The invertors of the foot were not the muscles at fault.
1905 Practitioner Nov. 680 As a flexor of the ankle, adductor of the front of the foot, and invertor of the sole, the action of the extensor proprius pollicis in its transposed position is greatly altered in quality.
1969 M. A. MacConaill & J. V. Basmajian Muscles & Movements xiii. 254 The tibialis posterior is an invertor in non-weightbearing movements of the foot.
2012 S. Agarwal Current Orthopaedic Pract. v. 147/2 The tibialis posterior is an invertor of the foot that originates in the deep posterior compartment of the leg.
3. Electronics and Computing. A device which converts either of the two binary digits or signals into the other, so that every ‘1’ is replaced with a ‘0’ and vice versa; = inverter n. 2c.
