That's the kind of info I need. I hadn't considered that aspect of design. Since these go on Canadian trains low temperatures are a concern an my first...
Gordon A thought comes to mind that you could possibly use polybutadiene acrylic acid acrylonitrile 85%(PBAN) and Liquid epoxy resin 15% (LER)along with a very...

For many years, I have used the Hakko 936 soldering stations. I just splurged and got one of the 937 stations with digital temperature control, and realized I...
Syd, We don't have the fancy digital units but the dials on our irons are calibrated in deg. F. I don't know how accurate they are, but we idle the irons when...
Weller maggnastat tips are calibrated in 100s of deg F. Tip #7 is 700F, #8 is 800 and #9 is 900F For surface equipment normally poeple use #7 while for...
Soldering is the one thing that determines success or failure for many of us and is the most simple yet complex thing we do! Answer: "The heat should be...

I have been playing with the new digital soldering station, and it looks like maybe 700 degrees F is good for the tin lead, and maybe 800 for the higher...
The digital temperature display could have application in production environments where assemblers may be tempted to crank up the temp. It's easier for QC to...
Another option that is used by the US Air Force in their Emergency Radios which are crash survivable. The modules are encapsulated in styrofoam. The nice thing...
I spent a good deal of time researching this issue a couple of years back. The rigid encapsulants are always problematic if you are going to "push the ...
Anybody have any 1990Y temperature probes out of the old GO/GOI/MLS differential temperature tools with open or shorted RTDs in them? I need a few housings to...
If you have a technical question, ask away. You will probably get answers. Buying and selling tools is one of the purposes of this list, but certainly not the...

I am looking for someone who can help me with a couple of perforation jobs on my deep hole in Hawaii. We need to perforate a 5" liner - ~18 lbs/ft - at a...
Don, I have 30 years in the perforating business and do only as call consulting jobs. Get in touch off line and I will send you a resume. Thanks, Loyd Reddig...
We have had great discussion on interpretation - like the subject of formation density thru casing (Dr. Calvert) and Neutron Density crossplots. How many are...
Chuck, can you recall when the discussion on formation density through casing took place? I would like to review the comments made. I currently run a...
Hello, dear friends, As we know, the resistivity of flushed zone in openhole is usually marked by "Rxo". Do someone know where the letters "xo" from, ans its...
The discussion was with reference to work being done by Reeves Wireline Services and a paper "Differentiation of Reservoir Fluids Through Casing - An ...
I would like to submit the following as a possible meaning... In the English language where we often use many words to describe things that could be described...
Interesting to hear your reasoning. Sounds plausible. I wondered about Rxo for quite some time, myself. Please let me know some good websites to gain knowledge...
Anybody have a favorite replacement fore the old Harris HA2-2600-2 OPAmp that SIE was so fond of? I have been getting away with using the CA3140 in most...
I doubt if the x means "ex" or has been. In the (electrical) engineering field R is the normal symbol for resistance as everyone knows. The letter X, usually...
Syd, A few ideas; The HA-2600 has a GBW of 12 MHz and 7v/usec slew rate. National Semi recommends their LM6161 to replace the HA-2600. The LM6161 has a GBW of...
Dennis, Thanks for the input. The concept of Rxo meaning Resistivity of the flushed zone surrounding a fluid drilled borehole was likely coined by the French...
