This was a precursor of the modern use of individual plug-top coils, where each cylinder has its own coil, thus avoiding the need for a HT distributor.

His generator featured a ring armature wound with many individual coils of wire.

The individual coils must have had about the same diameter as a manhole cover.

Dux's king bed features an "integrated spring system" that is a continuous interlocking unit, rather than individual coils.

These mattresses also use the gel-infused foam, as well as foam-encased individual coils that are pre-compressed and inserted into single fabric pockets to flex independently.

Minutes, and flying thoughts had made it-then came thousands of the individual coils, by thinking of one, and picturing it many times!

Other systems dispense with the distributor altogether and have individual coils mounted directly atop each spark plug.

This process utilises similar systems to bar end heating except that the whole of the billet is driven into individual coils.

For maximum performance, the C30A uses a direct ignition system, with individual coils positioned directly over each cylinder spark plug.

Coil springs are individual coils, open at both ends.
