I was thinking about a picture Maserati Convertible on one side and a Z-28
Camero on the other side, both red with black leather interiors.


We've seen entire buildings done up this way,
especially in Italy. When they are remodeling and
have those scaffolds covering the entire face of a
building, they put a cloth over the front and paint
on it the finished product! Very clever.

Actually what I need is a picture of the Home Lab with all the junk picked up
off the floors, a clean and organized workbench,
the stacks of boxes gone and everything stored and labeled neatly on shelves.
Unfortunately, no such picture exists!

Hello all,

I need a schematic as to how to make a battery converter for two 67.5 v
batteries connected in series to make 135 volts.

Or, maybe one here can direct me to one that can make it for me.   Allyn Goshy
is no longer taking such requests.

Steve

Can you elaborate on this?  Is Allyn's health at issue?

Yes,

In his one sentence reply he stated:

"I am sorry to say that because of health reasons I am not taking any more
requests. This has come up with out any warning."

He has rendered a valuable services to us all.   Let's hope that he is soon
well.

Steve.

A long time ago, when LENi's were still a young project, I did this one up in
Ludlum colors.

http://www.qsl.net/k0ff/Sweetwater%20LENi/

Ludlum is of course located in Sweetwater TX, hence the name.

Geo

Hope he gets well.

Till then, guess I will have to string fifteen nine volts together for the 135 v
that I need for my neat Sears Tower Scintillator.

The crystal is nominally ok, but I think I can restore it on my own.

Which way does the dot on the GV3A regulator tube go?  The reason I ask is
because my Victoreen 6A has a HV regulation issue (over voltage) and I want to
be sure the last guy who worked on it didn't create the problem.
Presently the side of the GV3A with the dot is connected to the HV output and
the other lead is grounded.  The schematic by Corey Hatch appears to show the
dot going to ground.

Thanks & eat lots,

Hello all,

I just won this and was floored with it when it arrived today.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250531354599&ssPageName=STRK:\
MEWNX:IT

These compasses were issued to U.S. engineers during WWII.   The first issues
early in the war were black inside with radium N, W, S, E. and some spots
between.   But the later ones made by Superior Magnito Corp. from 1945 even to
1949 were richly painted with radium.

The example that I purchased was made in July 1945 and it registers at 8 mR/HR
(gamma only) with a CDV-700 standard configuration as issued counter.

That is equivalent to a TYPE II deck marker! which registers between 6 and 10
mR/HR with the same CDV-700.

And what is more amazing is that it still glows without having been exposed to
outside light!

If you want one of these there are a number of these U.S. lensatic compasses
available on ebay.   The ones you should get would be the white face ones that
were made between Jan 1945 to late 1949 by "Superior Magnito Corp".  T hey are
easily spotted by the dark brown radium paint band on the inner white edge so as
to illuminate the compass.

The earlier black faced ones are interesting too, but they are not as active as
the later ones.

These are neat, cheap, highly radioactive, and also very useful if you get lost
out on a uranium mine excursion.

Yes I have one I got the hard way... serving in the army in 67-69.  It
is the hottest source I have...
Eric

Ouch Eric, can you spell TET offensive?

The little pocket compasses have radium too. They are made in a pocket watch
style case, manufactured by watch companies.

I found the answer myself when I located the Victoreen Tube Catalog on the web.
http://www.logwell.com/tech/app_notes/VictoreenCatalog.pdf

According to page 12 the red dot is on the anode (+) lead.

Think I'll try upload the catalog to the files section.

I have had my own field trips and today I went to the Grand Canyon with my buddy
doing a run on his U.S. Mail delivery route.

As a former Park Ranger for 10 years I have some inroads into access at the
Orphan Mine.   Whether I can take a few specimens might or might not happen.  
But at least I will check the site out.

On the way out of the park, I scouted out with my PRI 117 scintillator with
plastic crystal  some areas near the Canyon Airport and I found an old and very
extensive ore pile that came from the Orphan Mine.   It is barely evident now
covered with salt bush.

I was astonished at the readings that I was getting walking over it.   Pegged my
scintillator all the way up on the .25 scale, and mostly midway on the .5 scale.
And there were a few spots where it actually pegged the .5 scale, too!

But the problem is that with a scintillator that is so sensitive and standing on
a huge pile of ore it is difficult to sort out singular specimens.   I forgot my
CDV-700 which would have allowed me to find these amid the huge gamma background
radiation.

I am very impressed with the vintage PRI #117, and the new plastic crystal I
made for it.

It is great finding large deposits.

And the salt bush growing there... Highly radioactive!   At least 7 times
background.

I wonder if it is possible to use EDTA after these plants are dried, turned to
ashes, and the radium extracted with such?

I have been thinking of trying this for some time now.    And these old high
activity ore piles covered with plants might allow me the opportunity to do such
an experiment.

Steve.

hi-

I started this project about a year ago, and kinda forgot about it til now. It
is a disassembled victoreen CDV-700 6A with modifications. ON/OFF switch for
meter, 1/8 inch audio phone jack with on/off switch, and BNC. everything is
there, accept the BNC jack with i was going to install, never got around to do
it.  all you need is the BNC connector and to re assemble it and you have a high
price alpha/beta/gamma detector.

contains-
1.  GEOelectronics GEO-210 900v Pancake Probe (brand new)
2. BNC to BNC probe wire (brand new)
3. Complete dissasambled CDV-700 with modifications (DU check source)
4. 4 brand new Rayovac D-cell Batterys

-eveyrthing is complete, all the screws are there, battery covers, everything. I
am only selling this because i dont have time to finish the project.

great project, im asking $100 to get everything out of my hair. free ship.

kev  (if you need pictures i can get some.)

Actually,

The radium is completely contained under plastic and glass.   The later U.S.
Lensatic might even have a fluid that further keeps the radium contained.

Unless you break the compass open there is no danger of letting the radium
loose.

The deck markers are much less secure than the compasses, and in nearly all of
them that I have seen and sold, there are minor cracks that could pose problems
if the marker is not properly handled.

I usually re-seal these when I think that they might pose a danger with UV
curing epoxy which is not apparent when done right so as to take away from the
historic value of the piece.

But I think these U.S. Compasses are hot, if not really cool to have.  :-)

Steve.

Robert,

You are not too far from Oak Ridge, right?

That could be the reason.   A lot was radiological work was done there during
WWII.

As for me I grew up in Alamogordo in 1951 to 1955 before I moved to L.A. after
my father's death.   Well, I was constantly sick there, throwing up and such.

There were fields that my Dad told me never to go into, but that said, and my
curiosity enlivened I did anyway.   Spent hours upon hours roaming these open
areas with spent ammo laying about.   Who knows what I was exposed to.   And
then recently I was told that the our illustrious government (caretakers of the
people) might even have dispensed agents over the entire town of Alamogordo, p.
6,000 in 1955 to "test" the effects.

If true, nice of them, and hard on my childhood.

And I wonder now about this very rare immune disorder that has disabled me,
nearly killing me in 2003...

Could it be.... ? ? ?

Steve.

P.S.  But I am not so fearful of radioactive items.   I actually walked over the
Trinity site with my father in late 1954 or early 1955 when the area was
completely off limits.   So, that said, I must have gotten a pretty good dose
then.  I still have the green glass that we picked up.
