Subject: ? Fluorcarbon Elastomer bonding to Stainless Steels
From: larcjr@ix.netcom.com(LARRY R CORRIA)
Date: 11 Jan 1997 13:03:01 GMT
I am interested in any information which would allow me to bond a
fluoroelastomeric (fluorocarbon, not fluorosilicone) material to
stainless steels. So far we have tried treating the steel with
degreasing, sandblasting, Aluminum oxide coating, phosphating, and
chomic acid. There are products out there which have this construction
so I know it's possible. We are just having trouble finding out how
they produce their product. I am primarily interesed in steel
treatments and primer type of application to resolve this problem.
Also, if there are any environmentally friendly treatments would be a
great asset. Please respond directly, thanks.

I offer a product called CenBASE/Materials on CD-ROM for Windows, and now,
an online version on the World Wide Web. It is a complete electronic
compilation of today's commercially available material grades including
Thermoplastics, Thermosets, TPE, Metals, Ceramics, Rubber, Adhesives,
Composites, Fibers, and 5 US Military Handbooks. Over 31,000 materials,
110,000+ text based documents, 450+ MBytes of data, and 320 material
producers make up this software which is updated quarterly.
All property data references applicable ASTM, ISO, DIN, or CAMPUS material
property test methods. All data is reported in both English and metric
units of measure.
Using some keyword searches in the plastics database, CenBASE/Materials
came up with over 1600 materials when "automotive" was used as the
keyword. These can also be broken down by manufacturer as well (ie: GM,
Chrysler, Ford, Toyota, etc...).

simply reply to this message and a demo will be sent to you promptly.

The specific name of the glassware used in the procedure described below
is a pyncometer. It is small accurately sized flask with a ported ground
glass stopper. They are available from the major suppliers of lab
equipment.
Another method to consider if you can obtain "sheets" of the film is
based on Archimedes pricnciple. Weigh the sample in air, weigh the
sample in some liquid medium, this will yield the volume of liquid that
was displaced.

Subject: Getting flat plastic sheets?
From: vbv@giskard.cwru.edu ("Virgilio 'Dean' B. Velasco Jr.")
Date: 11 Jan 1997 20:28:38 GMT
I need to find some flat plastic sheets, preferably
some that are fairly rigid. I have some extruded Delrin
and Teflon, but they have too much bend in them. As
evidenced by a previous posting in sci.polymers, I'm
trying to anneal the Delrin sheets; however, I would
like to avoid this if at all possible.
Can anyone recommend a source of sheets that are
reasonably flat (preferably within about +/1 mm or so)?

Subject: Beware the Woodside "Literary Agency"
From: Jack Mingo

My apologies for the crosspost, but I'm trying to follow up on a
spammer/scammer who has posted 163 articles overnight. You may have
already seen warnings, but just in case:
The Woodside Literary Agency has recently posted ads in your
group. Beware of them--they are as legitimate as their forged e-mail
address.
People who have signed on with them have lost several hundred dollars,
and good number of their writerly dreams, to no good effect. There is no
evidence--and they've declined repeated opportunities to refute
this--that they've ever sold anything for any of their clients. In fact,
no editor I've asked has even heard of them.
Lately, they've been mailbombing one of their critics, and forging sex
messages with her phone number and address. You can see the whole sordid
story by searching on WOODSIDE or HITCHCOCK on Dejanews, or visiting the
misc.writing group. If you wish to complain about them, their real ISP
this week seems to be Earthlink (abuse@earthlink.net and
spam@earthlink.net).
Just for your information, if you are in the market for an agent, two
quick rules of thumb apply:
1. Legitimate agents rarely if ever advertise anywhere--most are too
busy turning away prospective clients to want to attract more.
2. No legitimate agent asks for money upfront. Real agents charge you
nothing until they've sold your writing, and then they take a smallish
percentage of the proceeds (10-15%).
Again, my apologies for busting in like this with a crosspost.

>machine is used for (generally, and specifically in materials testing),
simply, a hydraulic testing machine, as opposed to a mechanical
testing machine, uses hydraulic fluid to drive a piston and apply load
to a specimen. a universal servohydraulic test frame can be used for
static tension or compression testing, or for fatigue testing (cyclic
testing). hydraulic test frames use a servovalve to switch the
flowing fluid to the top or bottom of a double-acting piston and
thereby generate controlled motion. the feedback loop can be set up
so that a displacement, load, or the output from a strain device
controls the machine. the particular advantage to the sevohydraulic
test frame vs. the mechanical types is that the stroke distance and
speed of the machine can be varied over a very wide range without
having to do something like changing gears.
>the "theory behind the instrument,"
not much theory particular to the hydraulic test frame vs. other
hydraulic systems, just that a relatively incompressible fluid can be
used to transmit force smoothly and without the danger of rapid
expansion associated with, say, pneumatic force generation.

yeah, pretty easy. don't know what was wrong with those dweebs up

The reputation is intact. I used webcrawler to search for hydraulic
testing maching and got about 20,000 hits. The third from the top of the
list was SATEC and on the first mouse click was a listing for hydraulic
testing machines.
The reputation for young students to get others to do their work for them
by posting on the internet is upheld and verified in spades.
The reputation of the internet for having people who go out of their way
to be helpful (even when undeserved) is also upheld.
