Re: [PSUBS-MAILIST] ADS NewtSuit/HardSuit Applications

ORK! For 25,000 lbs bearing force, read twelve thousand five hundred pounds
- I was thinking of the elbow/shoulder (yeh, yeh, I know . . .the guy can't
tell his ass from his elbow!)

RE:     Re: [PSUBS-MAILIST] ADS NewtSuit/HardSuit Applications


Dear Frank D.
        If you check out OceanWorks website you'll see a poster showing
what appears to be the 'evolution' of the 'Hardsuit'  - Well, as my ol'
Grandpa used to say . . "don't eat that, Aylmer, that aint soup!".
All of these 'different' models are based on my 1980/90's patents on the
rotary joint. Understand that the 'suit' is nothing more than a big camera
housing or a very small one-atmosphere 'submersible that you wear'. 
All the old  ADS designs look similar - of course, they're  all
anthropomorphic. No trick to going deeper - make it thicker! The real trick
is the joint. At a thousand feet the pressure on a six inch diameter wrist
joint is 500 psi times the area of the joint - about 25 square inches -
about 25 thousand pounds of bearing force - 12 1/2 tons - near the weight
of a London double-decker bus. Now put that 6 inch rotary joint on the
pavement, pick up the bus with a crane and lower it carefully onto the 6
inch bearing/seal rotary joint until it is taking the full weight - now try
to spin the bus with one finger! Good luck!  That, in a nutshell (or a
'newtshell'), is the problem. The rotary style joint is used - in
combination with wedge-shaped spacers - to get a wide envelope of limb
movement. The joints of the suits immediately prior to the Newtsuit - the
'Jim' suit - 'Sam suit' - 'Wasp' - etc.all used variations on a ball and
socket joint developed in the UK by . Joseph (Salem) Peress in the
1920/30's.  So, why not a ball and socket?- after all, that's how our
joints work!  Yeah, but our joints don't have another limb running through
the center of them - imagine a big quarter-turn valve - stick your arm
through it - now try to close the valve to simulate movement between the
hollow ball and the rigid shell that contains it. The ball and socket
joints had very limited limb movement. That's why I went to a rotary
system.
        I set up a company called 'Hardsuits International Inc.' to
manufacture the Newtsuit, I took the company public in the early 1990's and
sold my interest in 1996. - The basic patent  had expired in 1994, I wanted
to build microsubmersibles, and I already had an idea for a new generation
of  lighter,cheaper atmospheric suits with a new type of rotary joint.(
Hence the 'Exosuit' that you can see on our website  - the first prototype
is in our shop now.) So . . . we've built dozens of compact deep-diving
subs,both sold them and operated them all over the world, I've much enjoyed
the long hours developing the Exosuit and it's various new components such
as the 'Prehensor' hand, the swimmable 'Newtfoot' ADS  fin, etc., - and
life is good. 

        Only one thing bugs the hell out of me:

        Why is  no-one  building 'amateur' atmospheric diving suits!!!!

         Hundreds of guys (like Psubbers) are building subs in their
apartment closets (or in Columbian bodegas (G), thousands of others are
building radical ultra-lights so they can fly! Amateurs are building
rockets and planning to one day get into space. Why aren't  there guys
building new generations of Newtsuits? Too tough to figure out the joints?
Hell, go to expired patents and copy them as a starting point! There are
tons (careful, though, most of them didn't actually work!) I don't, for a
second, under estimate the ingenuity of a basement or garage builder who
wants to build a new type of car, a new type of helicopter, a new type of
missile! Where are the new type of ADS  buiders?? .


        All the reasons for using ADS over ambient pressure sat or ROVS are
pretty obvious - and have been for the quarter century! Go to a thousand
feet in 5 minutes. Work there for 8 hours. Take five minutes to come back
to the surface. Grab a shower, snap a cold one one and watch TV. Beats the
hell out of 8 days of decompression in a smelly steel container!

Comments??

         P.S.Quick answer to your question, Frank: there are hundreds of
certified ADS pilots. We ( the little bitty ADS bunch) trained military,
scientific and construction divers - lots of 'em. The Newtsuit is used by
every major navy,; US, French, Italian, Japanese, Russian, Norwegian, and
so on. We also trained environmentalists, movie stars, treasure hunters,
archaelogists, an on and on.
