Re: [ARSCLIST] Early Stereo 1881 and 1931 (Was - Dynadoodoo
I believe these are all on the two Lps.I have lost my copy of the Oliver Daniels book,that discusses the Bell sessions in detail,perhaps someone else could post what he said here about them.

Keller interview was outstanding -- the BBC reporter had enough knowledge to ask intelligent
questions and didn't rush an older gentleman as he answered questions.
That report enhanced my understanding and appreciation of the Bell Labs LPs and also Ward Marston's
efforts in transferring those metal masters to tape. What I'm still not clear on, did Marston
transfer all of the Stokowski recordings, including the snippets, or just what's on those LPs? If
there is more, where are the tapes and why can't they be digitized and put online. Let me publicly
volunteer to bake (if needed) and transfer those tapes, gratis, if the LOC or Smithsonian will host
them online in full-resolution WAV format, and make them available to all.
Also, I highly recommend a reading of Dr. Keller's AES presentation:
http://www.aes.org/e-lib/browse.cfm?elib=3656
Dr Keller gives a quick and easily-understood summary of Bell Labs innovations related to electronic
high fidelity disk recording, stereophony, and related things. Perhaps most valuable, he references
and includes cover sheets of key patents.
Among the patent numbers worth checking out:
1981793 (Keller, moving coil pickup)
2069835 (Keller, gold sputtering of wax recordings)
1637082 (Maxfield, the Vitaphone 16" record and related technologies)
2014528 (Keller, two-frequency-band recording)
1910254 (Keller, multiplexed single-stylus system for 2 or more channels of audio)
2114471 (Keller and Rafuse, 45/45 stereo disc system) -- Keller notes that Davis and Frayne of
Westrex "reinvented ... in the 1950's" the Bell Labs system patented in the late 1930's.
1990548 and 2038216 (Keller, related to the "air advance ball" mechanism)
2612566 (Keller and Anderson, applying some of the air advance ball developments to computer-tape
systems)
2179261 (Keller, dielectric heating of vinyl preforms)
2025388 (Henning, Bell Labs' "Universal Phonograph Reproducer")
2161489 (Vieth and Wiebush, vertical feedback recorder)
2531242 (Yenzer, lateral feedback recorder)
