 Ahem, both were Motorola designs rather than NSC.  But I
 suppose it's possible neither were put into production.

Paper "1968_Frederiksen,Solomon_amplifier.pdf" is MC1554... the output
stage is my scheme... a sliding class-A version can be seen in the
MC1530/31 OpAmps.

Paper "Frederiksen_regulator_JSSC(1968).pdf" looks like am LM117
regulator.  I am unaware of what Motorola might have called it, I was
not involved with regulators at that point-in-time, just PLL's and
A/D/A (and I might have been away at Philco-Ford doing automotive
stuff :-).

Note that Figure 6 is my current mirror scheme (not credited in
standard Jim Solomon style).  He was a cretin who got his ass publicly
handed to him on a platter by writing a paper claiming he created the
Gilbert multiplier.

It'll take me a few days to got thru the patents (*), but US4607172 is
an NSC comparator, part number unknown, should have be found to
infringe my patent US3638041, MC1650/51 MECL Comparators.

(*) I use Patent Fetcher which restricts me to 6 per 24 hour period
without charge ;-)

When two patents cover the same invention it's called "interference",
not "infringement".

Google Patents is free.  IIRC some of the PDFs aren't OCRed.  Those
ones, I usually fix using any2djvu:

http://djvu.org/any2djvu/

I like the djvu format, and it's unlikely to be vulnerable to PDF
nasties anyway.

The patent examiner should have caught it.

Yup.  They only have about 8 hours assigned to each application, though,
and rely very heavily on keyword searches to find prior art.

Garrett Moddel of U Colorado and I (IBM) have almost the exact same
patent on waveguide-integrated tunnel junction optical modulators.  If
either of us had been able to make them work, it could have been an
interesting fight. ;)

It's possible to have the same invention described in quite different
terms, so that a simple keyword search doesn't find the prior art.

There's an appeals process in the USPTO that handles interferences and
re-examinations.  I've done a few re-exams--the rules are much more like
the initial examination and much less like a district court case.  The
patent owner has to prove his case in a re-exam, whereas in court
there's a strong presumption of the validity of an issued patent.

My 3,491,301 was initially denied.  Then I told the examiner he was
too dumb to understand it (I was only 25 at the time :-)  The examiner
allowed it ;-)

The RCA and EMI colour TV patents described the process of putting the colour information on a sub-carrier as "quadrature modulation" and "sine-cosine modulation" respectively. EMI patented it first, but the US court decided that the two descriptions implied different processes - they didn't say how - so the RCA patent stood - surprise, surprise.

 You're talking about Figure 6 in the Frederiksen
 sole-author regulator paper (not the joint paper
 with Solomon), right?  Tom credits you in a footnote:
 "This circuit was suggested by J. E. Thompson."
 Its purpose was to deal with very poor PNP beta?

Thanks, I missed that.  Yes, it side-steps the poor lateral-PNP beta
problem.

Slowman seems to have a mental deficiency requiring incessant
insistence on being a horse's ass.

Original release MC1554 was in a TO-5 can (MC1554G) and was thus rated
(optimistically) as 1-Watt, based on a slip-on finned heat-sink.

I lost a bet to Tom concerning how much power output could be
attained.  He opined some outrageous amount... I don't remember, maybe
10-Watts (after all, we're talking 50+ years ago).  I said, "No way".

I lost.  I came to work one Monday morning to find that Tom had come
in over the weekend and machined a slab of Aluminum such that a TO-5
could be force-fit into it.  He also drilled a pathway thru the block
with threaded fitting such that he could pipe CO2 thru it.  Voila!
10-Watts (or whatever grotesque amount ;-)

LM117 is the numbering assigned by National... I'm not sure if it was
(initially) made at Motorola Semiconductor Products Division...
Motorola SPD was heading into its final death spiral in that time
frame.

Jim Thompson seems to be suggesting that the mental deficiency was at Motorola - there's not a lot of point in developing a 3-Watt chip and selling it in a 1-Watt package. National Semiconductor didn't make this mistake with the LM12.

So he knew the score, even if you didn't.

Putting the MC1554 into a 1-Watt package would be evidence of that.

Rambling incoherent Jim Thopmson can't make any sense of it.

Jim Thompson is even worse than krw at making sense of stuff that he doesn't want to think about.

I've finally got Jim Thompson to identify a integrated circuit that Jim thinks that Tom Frederiksen designed, but Jim can't explain why the MC1554 ended up in a 1-Watt package, when Tom Frederiksen trumped it as a 3-Watt device (and demonstrated that you could get 10W out of it with a sufficiently bizarre heat-sink).

Perusing all of Tom's patents, only the two RExxxxx one's are assigned
to Motorola.  Neither of which can I attach a Motorola part number.

With that name I assume Jim had Swedish family background and I always 
knew that for some reasons Swedes were great engineers. RIP,

Oops, I mixed up Jim's name with Tom's. Sorry.
