[GreenKeys] Fwd: Tape Printer by Fairlawn Engineering Lab

There was also equipment made themselves or had made for them because
Teletype didn't make it.  They had a big shop in Chattanooga that was
able to manufacture just about anything, especially wired parts.  They
also used contract manufacturers.  The Desk-Fax machines were made in
Chattanooga.  W.U. liked magnet-driven tape readers rather than
motor-driven models for some applications.  One of their clever designs
is a loop-gate transmitter which reads the message directing
characters in the tape and then is able to re-read that portion of
the tape along with the rest of the message.  They had some typing
reperforators which, like the Kleinschmidt models, printed the
characters on the edge of the tape rather than down the middle.
They had a very nice motor driven keyboard perforator which was built
on the keyboard base of a Model 14.  Unlike the Teletype models it did
not require a big DC power supply to power a big electromagnet.
They designed a polar relay, manufactured by Automatic Electric, which
was was more compact than the 255-A and was good enough that Teletype
used it in some products.  They had a multi-magnet reperforator some
years before Teletype built a comparable product, the LARP.
