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 1, English, - diving%20apparatus

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 1, French, - scaphandre

By 1828 the device evolved into Deane's patented diving dress, the unit considered of a heavy suit to protect the diver from the cold, a helmet with viewing ports connected to the divers waist. The helmet had a connection for air to be pumped from the surface and the excess vented out the bottom of the hat. 4, record 2, English, - diving%20dress

Internal deceleration normally is achieved with built-in cushions; the length of the cushion sets the fraction of the stroke in which cylinder speed can be controlled. Cushions can be, and usually are, built into both the cap and head ends of a cylinder. A cushioned cylinder ... consists of a spear (on either or both sides of the piston), a mating cavity in the appropriate cylinder end to receive the spear, a needle valve to adjust cushioning speed and a check valve for quick start-up when the cylinder reverses its direction of travel and moves away from the cushion. 1, record 4, English, - cushion

[...] les vérins hydrauliques peuvent être dotés d’amortisseurs de fin de course, côté fond, ou [...] des deux côtés à la fois. [...] ces amortisseurs de fin de course sont souvent constitués d’un piston plongeur conique qui en pénétrant dans l'orifice d’alimentation l'obstrue progressivement, limitant ainsi le débit de fuite qui ne peut plus s’écouler que par un petit orifice calibré percé dans le couvercle. Le débit de fuite limitant la vitesse de déplacement du piston durant la course d’amortissement est alors déterminé par la section de ce petit orifice. Ce petit orifice peut aussi être réglable. Dans ce cas, il comporte un pointeau réglable qui permet de déterminer la valeur de la vitesse finale à imposer au piston. Le couvercle est aussi percé d’un second orifice équipé d’un clapet anti-retour permettant l'alimentation sans restriction lors de l'inversion du sens de déplacement de sorte que le piston ne soit pas freiné au démarrage. 1, record 4, French, - amortisseur%20de%20fin%20de%20course
