Re: [PSUBS-MAILIST] Design Protection (patent) Question

Steve

I forgot two more ideas that I am (borrowing), neither of which was mine.

Rick M Cog belt to drive shaft for possible 12v motor

Rick L Negative pressure regulators, to feed intermittent air to the diesel from the hp tanks should the snorkel close inadvertently.

I would not be able to do this but for the help I have recieved form this forum.

....Well...I for one am shamelessly stealing ...err....(borrowing), so far anyway....

Kittredge K350        Soft ballast tank arrangement, Thanks Dan H...as allways.

E-Boat         Bow bouancy tank from fleet boat as my fore and aft trim tanks

Peter Madsens Kraka     Snorkel Float, (which he borrowed, from Germany who borrowed from Dutch in turn).... fixed stern planes, and camera scope.

Sport Sub     Flat plate windows, round ports, Freeman Hatch

Caribsub     Material scantlings, diesel arrangement, poppet valve

That is so far! Steve, in my research, I have discovered that the history of submarine design is full of precisely this "borrowing" of the other guys stuff. We are in good company sir!....just keep your wallet close when I'm around! :)
