Subject: Sodium Hydroxide Container
From: Archibald
Date: Mon, 13 Jan 1997 20:02:54 -0500
Hello,
Help! I am currently processing parts through 180C Sodium Hydroxide
in a Teflon tank using an immersion heater covered in Teflon.
This heater has failed 4 times with the manufacturer (Lufran)
replacing it each time (at no cost) with new design modifications.
The solution is saturated and can become a solid; however, I never let
it get to this state to protect the heater. I would like to move the
heater outside of the soultion. My first try was a cast iron pipe
that was capped and used band heaters. This worked for the first
day and then the solution attacked the cast iron. I know that this
solution has attacked cast iron, both 304 and 316 stainless steels,
brass, aluminum, titanium, etc.
Does anybody have any suggestions for a container for this very HOT
and aggressive solution.
Thanks ahead, any help would be great

Subject: alternator model
From: cschwarz@icaen.uiowa.edu ()
Date: 14 Jan 1997 05:45:15 GMT
I need some help in modelling an alternator, i.e. a synchronous
generator plus a rectifier. I have equations of motion of a
synchronous machine. I'm assuming I can get by without modelling the
damper windings. The equations are of the form
E(w) dI = A(w) I + V (1)
-2J/P dw = Te - Ti (2)
The crux of the problem is this: When operating as a generator, it is
an inverse problem, since V is not an input but a result of the input
torque to the rotor. This is not a problem if you assume you're
connected to an infinite busbar as is done with large generators;
however, we can't assume that here.
Anyone know how to handle this???
Thanks in advance for your advice!

This may not be what you are thinking of, but,... we used very fine
aluminum powder in water for flow visualization. There may have been a
wetting agent (somehow glycerin sticks in my mind?) also used at the same
time. Al powder is used as pigment in aluminum paint, and it's nasty to
breathe -- wear a mask until all the powder is in the water.

Nickel holds up very well to hot caustic. I used to run reactions at pH
14 at 300 deg C (supercritical) in a Nickel autoclave liner, and there was
no
visible pitting. The autoclave also employed an agitator, which was made of
Nickel as well.
You would probably be better off with a jacketed tank, with the inside
walls made of Nickel and the outside carbon steel. You could then apply
steam to the jacket to heat the caustic. Employing a mixer will also be
beneficial, since this will avoid hot spots and decrease corrosion.
Nickel is rather expensive, but not as much so as Titanium. Teflon has great
resistance, but is poor for heat transfer. Try using a Nickel immersion
heater. With no agitation, the elements get too hot and burn out. Even if
you just bubble Nitrogen through the bottom of the tank this will be an
improvement over natural convection. It would be good to install a
thermocouple directly on the heating elements, and cut them out when the
temperature becomes excessive.
Is the sodium hydroxide anhydrous?

Good question. When are European patents going to be on the net. The
US PTO has this, and can make some money from their service by charging
people who want complete abstracts. Not that I like government in
business, period, but this seems like a useful thing that did not
cost them much to do.
Also, European patents cost a fortune and clearly favor big business
ove small fry.

Man, you spend 8 years in grad school and the moment you come out into
the ".com" world, Bozo the ".net" Clown gives you grief. Sheesh, some
people really ought to get a life.
anyway. I've used the Citation Indices - but they are an incredible pain
to search especially if you're interested in wide area searches. I've
searched through the CD_Rom collections before as well, but I don't have
access to those anymore and the univ libraries don't give you access any
more even if you're willing to pay for a search.
so I rephrase : Does anyone know of a site/company that I can do some of
these searches, or get some of them done for a fee ? I looked through
some search engines but didn't come up with a whole lot.

Since its release in January 1995, I have heard a number of complaints
regarding the cost of American National Standard ASME Y14.5M-1994,
"Dimensioning and Tolerancing." Many designers feel that the $85 cost
per single copy (ordered directly from ASME) is much too high.
In 1984, I purchased a copy of ANSI Y14.5M-1982 for a total cost of $42
(including shipping and handling costs). I remember thinking then how
outrageous this cost seemed to be for a 150 page book when comparing it
to other books of approximately the same length.
In 1997, the latest version of this standard, ASME Y14.5M-1994, costs
over twice what I paid ten years earlier. Granted, inflation alone
contributes to some of the cost increase. Plus, the latest version is
84 pages longer than the 1982 revision of the standard. But, the cost
of printing the book should not be the only factor considered when
analyzing the cost of this document.
It is unfair to compare ASME Y14.5M-1994 with a book written by a
private individual. ASME Y14.5M-1994 is a national consensus standard
on dimensioning and tolerancing principles and concepts. To acheive
this consensus, ASME must draw on the expertise of approximately 100
individuals throughout the United States; from all types of industry, as
well as the academic community. Consider the costs associated with
coordinating such an effort. ASME must arrange and pay for meeting
rooms, support staff, long distance phone calls, faxes, postage, tons of
paperwork, etc. ASME has been "footing the bill" for these development
costs for the 12+ years since the last revision to this standard.
As to content, ASME Y14.5M-1994 is NOT just a repeat of the same old
information with a fancy new cover. It's true that the older
tolerancing concepts illustrated in previous versions of the Standard
are still there. But, ASME Y14.5M-1994 adds numerous NEW tolerancing
principles and concepts not available under previous versions. These
new tolerancing "tools" correspond with the latest in manufacturing and
verification techniques. Plus, the new version of the Standard brings
with it a new standard, ASME Y14.5.1M-1994, "Mathematical Definition of
Dimensioning and Tolerancing Principles" which provides the needed
mathematical rigor to tolerances in a computer-based maufacturing
environment.
If you think that ASME Y14.5M-1994 costs too much, consider the cost of
ISO standards related to dimensioning and tolerancing. To get the
equivalent information under ISO, you must order approximately 24
different standards and technical reports. Total cost: well over
$700.00. These standards are compiled under ISO Handbook #12 for a cost
of $120.00 (last time I checked). But the ISO standards are behind the
tolerancing technology depicted in ASME's standard. By comparison, ASME
Y14.5M-1994 is a bargain!
Why can't you order it through a book store? I'm not sure. But, I
don't know of any Industry or Military Standard that you can order
through a book store at the local mall. But, there are a number of
excellent reference books you can obtain which are based on ASME
Y14.5M-1994. Some books I recommend are:
"Geometrics III" by Lowell W. Foster (Addison-Wesley Publishing
Company, Inc.)
"Design Dimensioning and Tolerancing" by Bruce A. Wilson (The
Goodheart-Willcox Company, Inc.)
"Geometric Dimensioning and Tolerancing" by Gary Gooldy (Prentice Hall)
"Geometric Dimensioning and Tolerancing Workbook" by Al Neumann (TCI,
Phone:941-383-4283)
There are several other good reference books, however I don't have
specific information on them.
Yes, the latest version ASME Y14.5M does cost more than it used to. Is
the price too high? Maybe. But, considering what goes into the
development, I don't think it is too far off the mark.

Scott,
I don't even pretend to know the detailed differences between the
two degree programs. However, I can tell you that in Tennessee and Alabama,
you CANNOT become a professional engineer with an E.T. degree. You must

I remember seeing an account of someone who claimed to be setting
a speed record for a bicycle, and got up over 100 mph (the number
134 mph comes to mind, but I might be inventing this). The way he
did it was, of course, to remove drag by `drafting' in an enclosed trailer
that matched pace with him and did all the work of fighting the wind
resistance for him. This probably represents the limiting case, where the
vehicle in front is taking ALL the wind load, and the vehicle in back
is only overcoming rolling friction.
