These cylinders of compressed gas (just air, I think) were larger than modern CO2 cartridges, and the French term is "gonfleur". A search for this term pulls up various images, such as this one from Flickr..

Gonfleur can also refer to a pump, so some confusion is possible.

I seem to recall various discussions of these in the past on bikeforums, so if someone wants to find out more, it shouldn't be too hard.

Interesting!!
BTW, those size CO2 cartridges have been around for a while. The ones that fit the old seltzer bottles from the '60s are very similar in size and shape, although they are unthreaded. Makes me wonder if some machinist wouldn't have made some inflator back in the day for the "Sparklets" cartridge.
