  • General Electric MK10
    the nature of the ocean environment In October 1971 this security was shown not to exist A US submarine Halibut visited the Sea of Okhotsk off the eastern USSR and recorded communications passing on a military cable to the Khamchatka Peninsula Halibut was equipped with a deep diving chamber fully in view on the submarine s stern The chamber was described by the US Navy as a deep submergence rescue vehicle The truth was that the rescue vehicle was welded immovably to the submarine Once submerged deep sea divers exited the submarine and wrapped tapping coils around the cable Having proven the principle USS Halibut returned in 1972 and laid a high capacity recording pod next to the cable The technique involved no physical damage and was unlikely to have been readily detectable The Okhotsk cable tapping operation continued for ten years involving routine trips by three different specially equipped submarines to collect old pods and lay new ones sometimes more than one pod at a time New targets were added in 1979 That summer a newly converted submarine called USS Parche travelled from San Francisco under the North Pole to the Barents Sea and laid a new cable tap near Murmansk Its crew received a presidential citation for their achievement The Okhotsk cable tap ended in 1982 after its location was compromised by a former NSA employee who sold information about the tap codenamed IVY BELLS to the Soviet Union Ronald Pelton a national Security Agency employee told the Russian about the project in the 1980s This turncoat received a mere 35 000 for this information from the Russians One of the IVY BELLS pods is now on display in the Moscow museum of the former KGB The cable tap in the Barents Sea continued in operation undetected until

  • First Dutch Optima Dive
    would like to use a different harness than you can simply change it If you want a different back plate that s also possible You can hook up the actual rebreather to whatever back plate harness wing configuration you want Although I really like the back plate and harness the unit came with The harness could have used slightly larger bands to ease getting into the unit on a rocking ship but for the rest it was very comfortable I did have issues with the routing of the inflator hose That really got in my way and I would have really much appreciated having that further to the outside I also noticed that the cables from the secondary and the DIVA HUD ran precisely along the handle used to lift the unit Not a really nice place to have those cables as I don t think they can lift the unit It s time to go diving I called a dive buddy of mine Stephan Leushuis to make this dive His instructions were nice and easy as with all my OC buddy s If he s in doubt send me to the surface I then showed him all 4 inflator buttons he could use to get me positively buoyant Nice detail is that you can simply press the diluent inflator but you have a sliding button for the oxygen That way it s much more difficult to accidently inject the wrong gas into the loop Time to really go diving As I walk into the water I keep pre breathing breathing the unit on the surface to test if there s CO2 leak and keep a close eye on the PO2 values A final 02 flush to give the calibration a final check and it s off we go Perfect First we remain at 2 meters for a small minute That gives me time to go over the Hammerhead and listen for bubbles Stephan will be doing a bubble check at the platform we re headed to Everything seems fine and off we go The Hammerhead keeps an almost perfect PO2 and after a short swim we arrive at the platform where I can practice some drills and Stephan can do the bubble check The drills go nice and smooth Loss of O2 stuck solenoid partial loop recovery Every thing is well I have to say the Hammerhead gave me a scare The two handsets are totally independent and they seem to pick a PO2 value and display that for 2 seconds or so But this means that during an 02 flush the primary read 0 6 bar PO2 whilst the secondary was already up to 1 0 bar It s not a real problem but it is something you should be aware of In general the Hammerhead out performs my Inspiration on all counts It can easily take my Inspiration 1 or 2 minutes to reach a stable PO2 of 1 3 bar after switching from 0 7 The

  • Hippocampus Celti by Tom Rose
    stainless steel bands to help me hold the tanks and scrubber in place It is a damned good thing that I got Allan to do it because I can t make simple iron welds much less thin stainless steel The cover is on the right The case is 1 4 inch black PVC and the cover is 1 8 inch blue polyethylene Both are thermoplastic materials Each started as flat stock and were heated with a heat gun and bent into place to fit Note the holes in the cover They match up with disks on the side of the case to hold the cover in place I used a cheap 2 inch hole saw to drill the cover This is because cheap hole saws have thin walls Then I used the same hole saw to cuts disks out of scrap case material I sanded undercuts on the disks to help hold the cover on when it would be in place After putting the cover on in the exact place I wanted it I glued the disks to the case through the cover holes with PVC cement It came together quite nicely Starting the loop tour at the mouthpiece The mouthpiece is one of the only RGU parts left but it is modified in that a shutoff has been installed The RGU hoses have been replaced by new US Divers replacement hoses to reduce Work of Breathing WOB Red on port side exhausted air and green on starboard side inhaled air To make the hoses fit I put PVC unions into a lathe and made hose barbs Then I heated the other end and slid them on the RGU hose fittings Exhausted air goes down the hose to the scrubber The scrubber is made of 4 inch PVC Sorb Screens are modified snap drains from Home Depo backed up by air condition vent filters The top seal of the scrubber is the dual display It is held on by stainless steel draw snaps and has an o ring seal Screw on fittings attach the hose to the scrubber port another fine product from Lowes The exhaust air red marked hose enters an external tube to the bottom of the scrubber There is a water trap in the bottom of the scrubber The air flows up the scrubber and out a port through a short hose into the counterlung Another of the few parts of the original RGU that are left These include the counterlung port and the hose I just cut a hole in the snorkel vest and added the port from the RGU If you look closely you can see how the o ring fits on the scrubber The O ring support ring is a cut off PVC pipe cap that has been reversed and glued in place Air from the scrubber goes back to the mouthpiece from the counterlung through the green starboard marked hose Again you can see the front view of the display the side snaps
