La communauté de plongée récréative technique et scientifique utilise trimix depuis de nombreuses années pour diluer l’oxygène avec un mélange d’azote et d’hélium au lieu de seulement utiliser de l’hélium, en grande partie pour réduire le coût élevé de l’utilisation de l’hélium. 1, record 1, French, - trimix

Record number: 3, Textual support number: 1 CONT
Diving Apparatus. Any equipment to enable a person to spend time underwater. Diving bells were in regular use in the 17th century, the diver breathing air trapped in a bell-shaped chamber. This was followed by cumbersome diving suits in the early 19th century. Complete freedom of movement came with the aqualung, invented by Jacques-Yves Cousteau in the early 1940s. For work at greater depths the technique of saturation diving was developed in the 1970s in which divers live for a week or more breathing a mixture of helium and oxygen at the pressure existing on the seabed where they work(as in work on North Sea platforms and tunnel building). 3, record 3, English, - diving%20apparatus

Record number: 3, Textual support number: 1 CONT
Jusqu'en 1943, il était dangereux, sinon impossible, d'évoluer librement sous l'eau, les scaphandres «pieds lourds» utilisés à cette époque étaient reliés à un bateau par un «cordon ombilical» qui amenait de façon plus ou moins régulière l'air sous pression au plongeur. La lourdeur de scaphandre rendait le déplacement difficile. Jacques-Yves Cousteau et Emile Gagnan ont l'idée d'équiper le plongeur de bouteilles d'air sous pression reliées à un détendeur de gaz muni de valves qui amènent l'air au plongeur à la bonne pression : ils mettent au point le scaphandre autonome. Ce système simple et souple va permettre pour la première fois, en augmentant la durée de la plongée mais aussi l'autonomie de déplacement, d'observer et de suivre sans danger la faune et la flore aquatique. Il a été et est toujours utilisé pour la recherche sous-marine, mais également lors de nombreux travaux sous-marins : constructions de pipe-lines, renflouages de bateaux, etc. 3, record 3, French, - scaphandre
