Acetylene

I don't always have access to electricity, so I use a portable acetylene torch for welding.

Thankfully, electrical lighting has virtually eliminated the need for acetylene headlamps.

Cassini's atmospheric sensing instruments have revealed other carbon compounds, too, such as benzene and acetylene.

The acetylene gas lighting in the station offices and platforms at Kyle of Lochalsh recently has been replaced by electric lighting.

Mrs. Winnie had kindly sent her limousine car for them, and it stood throbbing in front of the hotel-entrance, its acetylenes streaming far up the street.
