![]() The combined CO2 scrubber/thermal regenerator unit reduces this in three ways:īy containing the scrubber/regenerator within the insulated survival bag eliminates immediate contact of this unit with the colder bell gas.Īs the carbon dioxide is 'scrubbed' from the diver's exhaled gas within the sodalime canisters, heat is created by this chemical reaction thereby warming the gas. Respiratory heat transfer is extremely high in heliox environments due to the density of the gas and the physical properties of helium. It has a pneu seal and a split band head strap. The oral nasal has been selected for comfort and efficiency. The canisters includes a dump valve prior to the regenerator to regulate return gas temperature. This material has been shown to have a higher scrubbing efficiency than conventional absorbents. It is contained within a satchel which contains foam protection. This pack contains the hardware from the Standard Pack 2 minus the rations. The CO scrubber holds a 2.5 kg charge of MP 797 sodalime.įor use within a hyperbaric lifeboat or rescue chamber. The thermal regenerator was designed by Robert Gordon's Institute of Technology to give 95% heat recovery in a helium environment at 300m depth. Fresh gas is taken from the bell environment through the thermal regenerator to the oral nasal. Exhaled gases are passed through the CO2 scrubber to the thermal regenerator fitted into the survival bag wall. The system contains a passive, lung power CO2 scrubber unit and thermal regenerator system. This pack contains a carbon dioxide scrubber/thermal regenerator assembly, a ration and water pack and sanitary bags. Most major International Diving Contractors have installed the Divex Bell Survival Kit to their dive systems. It provides a 'safe haven' for the diver offering thermal protection and gas conditioning. The Divex Bell Survival Kit is for use in Diving Bells, Hyperbaric Lifeboats and Underwater Welding Habitats in the event of a 'lost bell' or emergency situation. These men were landed at Lorient on 6 September and handed over to Germany as prisoners of war while the remaining men, one Belgian and five Irish, were allowed to return home.DIVEX BELL SURVIVAL KIT PACK NO. The port lifeboat was treated differently, as among the nine crew aboard were three from nations hostile to Vichy France. Pierre, which subsequently transferred them to a Spanish trawler that landed them at Pasajes on 13 September. The starboard lifeboat, containing the master and eight crew, was picked up by St. The lifeboats proceeded separately, eventually being rescued by two different French fishing vessels. He then provided rations, cigarettes, and alcohol before sinking Luimneach with U-46's deck gun. ![]() Having left their ship in a single, overcrowded lifeboat, without provisions, Endrass ordered them to return and launch the second lifeboat, which they did. Endrass also reported in his log that the merchant crew "lost their heads completely" at the shots across their bow, adding to the confusion aboard a netural-flagged vessel under fire in a time of war. Among the crew of Luimneach were three men from belligerent nations (two British and one Maltese), and it is possible that is why the merchant crew abandoned ship. Some confusion existed between parties in this incident, with the merchant crew believing the submarine was Italian while Endrass was unsure of the nationality of the ship he'd stopped. Two days out of port, she was stopped in international waters by the German U-boat U-46, under the command of Engelbert Endrass, with two shots across her bow about 170 miles west-southwest of Ushant. Although her cargo could be considered war material, as both her port of origination and destination were neutral parties she sailed under guaranteed neutrality protections as provided by the Law of Maritime Neutrality. Luimneach departed Huelva on 2 September 1940 under the command of Eric Septimus Jones, transporting 1,250 tons of pyrites back to Drogheda in Ireland. This event resulted in the death of one crew member. While in their service, in October 1938 during the Spanish Civil War she was damaged by bombs in the harbor at Valencia, Spain, but repaired and returned to service. The ship's new owners renamed her Luimneach, the Irish for Limerick. The ship served primarily as an ore carrier on runs between ports in Spain and her home country for seven years before being sold to Irish owners, the Limerick Steamship Co, with whom she operated for the remainder of her career.
