Well, I did see some gigantic Ingersoll one-lung compressors in a factory here on a tour. I was amazed they were from 1952. Gigantic horizontal cylinder about 8 - 10" diameter and probably a stroke of a foot. It may have been driven by a low speed synchronous motor that was supplying power factor correction in addition to driving the compressor. -- Ned Simmons |

I didn't mention those details as they have nothing to do with the air supply, but that was the setup. On the way was a phase angle meter that looked like it came out of Edison's own lab. I never found what the phase meter controlled, but it would have to be a variable voltage rectifier, probably with big Tungar bulbs in it. Jon |
