Hi,

	I spent some time in the library looking through the microfilm
readers for magazine articles regarding personal submersibles. Here are 
my results.

Regards,
Ray

"Build this two-man sub for $400"
W. K. Markham. 
il Pop Mech 135:94-7+ Je '71
Copy: 	from microfilm, photos are in terrible quality, drawings not too bad,
	text is readible.
Synopsis: 
	It's two man if the second man sits in the forward cockpit with
	full scuba gear on. The pilot sits under a 1/4" Acrylic plastic 
	canopy holding an air bubble. So its a semi-dry, ambient pressure
	sub. Neutral bouyancy is established by (bad ascii picture):

	wall of cockpit

	The pipe pivots at elbow. When straight down cockpit has the least
	amount of water which makes the sub the most bouyant. When up at around
	45degrees then the sub is neutrally bouyant. When up at horizontal
	the sub is negatively bouyant. When the end of the pipe is above
	water level then air in the cockpit escapes and allows water to come
	up the to end of the pipe which makes the trapped air bubble smaller
	or less bouyant. Since the pilot continually breaths from
	a scuba regulator air keeps getting introduced to the cockpit at
	ambient pressure and the pipe lets any excess out.

	Based on design from article "Build yourself this one-man 
	sports submarine."

R. Q. Riley and D. L. Carey
il Mech Illus 74:52+ Jl '78
Copy: 	from microfilm, photos are in terrible quality, drawings not too bad,
	text is readible.
Synopsis: 
	Not really a submarine. Its more a tri-maran (SP?) that that can flood
	a ballast tank in the center hull to make it negatively bouyant. So
	the center hull sinks, but the two outrigger pontoons still hold it up.
	Max depth of cockpit is about 40 inches.
	Two electric motors for about 2 knots
	Uses compressed air to blow ballast tank.
	Cockpit is dry with air being blown in from one pontoon and blown out
	from the other pontoon with electic fans.
