The detected eloptic signals were fed to a three-stage vacuum tube RF amplifier and conducted to a flat touch plate surrounded by a copper wire bifilar coil.

Some bifilars have adjacent coils in which the convolutions are arranged so that the potential difference is magnified ( i . e ., the current flows in same parallel direction ).
13.
The bifilar coil ( more often called the " bifilar winding " ) is used in modern electrical engineering as a means of constructing wire-wound resistors with negligible parasitic self-inductance.

15.
When used in a switching transformer, one winding of the bifilar coil is used as a means of removing the energy stored in the stray magnetic flux which fails to link the " primary coil " to the " secondary coil " of the transformer.
16.
Among the features are : titanium and composite main rotor blades, a bearingless composite tail rotor, bifilar vibration absorbers, and a simplified main rotor transmission . " The operative parts of the quote being : " [ Among the features ] developed for the UH-60 Black Hawk helicopter [ are ] a simplified main rotor transmission ".
