Currently conducting my own research based on the keywords in your post.

Anything further you can offer, will be expounded further upon later when I have my wits about me -- minimally in my notes, but I'll probably post some findings.

google books has archived all f the periodics from past years.

Charles P Tripler had a company that was a major producer of liquid air before Industries were monopolized and resource allocated as we know them today.

There are many articles on Nature, Electrical Journal etc, go to the 19th century.

I will try and post more information later.
