Hi folks - Here is the Friday Element Quiz Answer:
The Question:
This element is the only rare earth element credited as being discovered
in the United States. The ancient Latin name for a town in France. What
element is being described?
Bonus Question:
Provide the ancient Latin name and the modern name for the town in France.
The Answers:
The element is Lutetium (Lu). Lutetium was independently discovered by
Carl Auer von Welsbach and Georges Urbain in 1907/1908. A number of names
were proposed by both gentlemen for Lu and the name Cassiopium was used
for the element in Germany for a number of years. Lu is the heaviest of
the rare earth elements and is one of the rarest - only 0.0001% is found
in monazite ores/sands. The American Chemical Society also recognized
American chemist Charles James for also discovering Lu in 1907. Charles
James and his students at the University of New Hampshire produced a small
amount of Lu by a recrystallization process after going thru several tons
of ore but he was cautious about publishing the findings and missed the
opportunity to claim the discovery. A pure sample of Lutetium was not
produced until 1953. The name Lutetium is derived from ancient Latin name
for Paris (Lutecia).
The winner of the weekly element quiz is Amol Kane,(Amol - who are ya
working for ?). And per the Rockwell Collins firewall time stamp with a
same exact response time, the winners of the Bonus question are Dewey
Whittaker, Honeywell and David Bealer, Watch Fire Signs. So the boys are
going to split their time this week - they intend to work for Amol for 3
days, then Dewey for 2 days and David for 2 days, I expect Clumpy and
Kloumpios will suggest I don't use bonus questions in the future.
So far Clumpy and Kloumpios have done the following:

-I need them to help me start-up a new (used) Vitronics/Soltec wave
machine we recently got here. It's gonna' be fun (if that's what you want
to call it), we have to fill the Vitronics with a tin wash so we can get
the wave formers and nozzles out, clean everything up, and then empty the
pot. Then we've got to empty the pot in the old Electrovert machine that
we have and have that solder ready for the Vitronics. Then we'll play
musical wave machines by moving the Electrovert and placing the Vitronics
where it was sitting, then we'll fill the Vitronics again.

- Now I have two guys to assist with four screen printer moves this week.
They're gonna love helping me perform our quality verifications, and they
get to try their hand with cross section work again.
Week 20 Denny Fritz
- My first thought for Clumpy and Kloumpios was to ask if they knew how to
drain swamps. It has rained here in Indiana almost every day for 10 days,
and is forcast to thunderstorm for almost ten more. Any chance Kloumpios
has any biblical roots and is related to Noah of Ark fame?? At the very
least, please have Graham Naisbitt ship some wellies (Wellington boots)
here to Indiana for the coming week. Only slightly more seriously, what do
Clumpy and Kloumpios know about counterfeit components? Any day, I expect
to be thrown into that messy topic to support the Department of Defense.
And, what clearance do the guys have - confidential, secret, top secret,
or keep-from-telling-Doug?. Can either run an XRF or SEM? I presume they
have eagle eyes, so they can observe components through our optical
microscopes. Finally, is either carrying a small spare lead-acid battery?
Our UPS unit protecting the instruments from the too frequent lightning
surges crapped out last week.
