Jay,
I was hoping that with the older patents now being available, it would open up information we hadn't seen before. So I think that's pretty exciting. I was going to search for some more Lake patents yesterday, and decided that would likely open up a whole can of worms I wasn't ready for just yet. I currently average 35 web pages open at one time, because I haven't finished reading and exploring them. Not to mention all the PDF files and what not. I'm lucky now that I have a separate CAD computer so I don't drag down the CAD software with other computer operations like internet exploder pages. I was hoping there might be some patent drawings we hadn't seen before, that showed more data on the Argonaut's. Perhaps even some good side, top, and front profiles.
Regards,
Brent Hartwig

Brent,
The Lake patent links lead me to search through the Patent banks
and found a large number of Simon Lake patents that demonstrated his entrepreneurial
spirit. The scope included subs, salvage, engines, aircraft, concrete
structures, and medical apparatus…it was really surprising.
Earlier this year had considered a position as maintenance
manager for a SubCat S-30 that was to be refitted in Florida during a
relocation from Greece to Antigua. After review of the engineering and
operation complications of the design, poor operating location, and 18% tax in
Antigua backed out of the job. If everything went OK with the overhaul,
the submersible should be operational now. Both diesel pods exhibited
signs of heavy flooding after only a year of initial operation. An excessively
lengthy time was required to surfaces the sub completely so that passengers
could transfer through the aft hatch vice the top hatch. Due to this
wasted time and the extreme amounts of air required to surface fully, fewer
dives could be made in a day and this impacts negatively the passenger
load that can be carried in a given day. It also resulted in lengthy air
bank recharging during the night that would require competent attendance.

Jay,
I found that patent data late last night and so didn't get a chance to read
through it and notice the Lake patent details. I looked at it again so see if I
could perhaps look up the Lake patents as well on Google, and found them. ;)'
In the past nothing much was available on the internet for patents that
were issued prior to 1972. So this opens up a whole new resource for
allot of people. Here are the links to the two Lake patents you mentioned
if you don't already have them.
http://www.google.com/patents?id=kJFeAAAAEBAJ&dq=1,510,283
http://www.google.com/patents?id=-VRNAAAAEBAJ&dq=1864837
In regards to Prior Art I have found the USPTO to be pretty lax and allow allot
of utility patents to go through with claims thats are not really new, just
used perhaps slightly different but still the same mechanically speaking. One
case of this is the cross over between some claims on the Bionic Dolphin patent
and Hawks Deep Flight patent. Some of the claims in the Hyper-Sub are already
prior art in the SubCat S-30 built in 1999. Regardless of that, they are both
very interesting subs with unique design elements. I'll have to look through
the other Prior Arts sited to see if there is any thing about the SubCat design
as well as see if there are any US or international patent data on the SubCat
design.
Have any of you guys been on or personally seen the SubCat S-30 ??

Brent,
An interesting point to note in the patent listed below that
covers the Hyper-Sub is that the first two patents in the Prior Arts section
are Simon Lake’s.

Thank you for the interesting links Jay. I hadn't kept up on the
progress of the Marion Hyper-Sub. I've been interested in that front window
design, since I first saw it. I would like to see a stress analysis on it as
well as see how it's sealed at the edges. Here is a interesting link to there
patent data on Google Patent search. The drawings are interesting.
