1836 E. Howard Rattlin xx I shall call them the pulsating and the gyrating leg... Whilst you were admiring the undulating grace of the pulsator,..you would find the gyrator had stolen a march upon you.

1895 H. Stopes in Athenæum 7 Sept. 325/3 Beautifully made [stone] axes, knives, gyrators.

1908 Westm. Gaz. 15 Jan. 3/3 ‘It's called a diable... He belongs to the best Diabolo Club, and he's never heard it called anything else.’ Then he consulted the directions which had come with the box. The first of them began, ‘Place the gyrator on the ground.’

2. A passive circuit element which has two pairs of terminals and introduces a phase shift of 180 degrees for one direction of propagation but no phase shift for the reverse direction.

1952 Bell Syst. Techn. Jrnl. 31 1 The microwave gyrator has been realized by making use of the Faraday rotation in pieces of ferrite placed in the waveguide.

1952 Bell Syst. Techn. Jrnl. 31 3 Network synthesis today is based upon the existence of four basic circuit elements: the capacitor, the resistor, the inductor, and the ideal transformer... The introduction of a fifth circuit element, the gyrator, would lead to considerably improved solutions for many network problems.
