Closed Circuit Oxygen Rebreathers
- For more information see Porpoise (make of scuba gear)#A make of diving oxygen rebreather.
Eldred's initial efforts were to make an oxygen rebreather safe for sporting use. Pure oxygen used in early rebreathers causes CNS poisoning below 33 fsw. Eldred reasoned that the rebreather should be designed to stop flowing oxygen when the diver descended below that depth. At a demonstration by the Flinders pier, on Western Port Bay, south east of Melbourne, a diver passed out because he failed to purge the system of air. This failure to purge had resulted in a nitrogen build up. Eldred realized at this point that he needed to turn his efforts toward open circuit compressed air breathing apparatus. He was accompanied on this demonstration by Bob Wallace-Mitchell, who would become his distributor.

Famous quotes containing the words closed, circuit and/or oxygen:
“Don: Why are they closed? They’re all closed, every one of them.
Pawnbroker: Sure they are. It’s Yom Kippur.
Don: It’s what?
Pawnbroker: It’s Yom Kippur, a Jewish holiday.
Don: It is? So what about Kelly’s and Gallagher’s?
Pawnbroker: They’re closed, too. We’ve got an agreement. They keep closed on Yom Kippur and we don’t open on St. Patrick’s.”
—Billy Wilder (b. 1906)
“We are all hostages, and we are all terrorists. This circuit has replaced that other one of masters and slaves, the dominating and the dominated, the exploiters and the exploited.... It is worse than the one it replaces, but at least it liberates us from liberal nostalgia and the ruses of history.”
—Jean Baudrillard (b. 1929)
“All the oxygen of the world was in them.
All the feet of the babies of the world were in them.
All the crotches of the angels of the world were in them.
All the morning kisses of Philadelphia were in them.”
—Anne Sexton (1928–1974)
