Subject field(s)
  • Tracks and Roadways (Rail Transport)
DEF

Any progressive fracture which occurs in the head of a rail and has a transverse separation, however slight. This general classification is made when the defect is found in track. After the rail is broken for examination, the transverse can be accurately identified as one of the following : transverse fissure, compound fissure, detail fracture from shelling, detail fracture from head check, engine burn fracture, welded burn fracture(see those words).

OBS

transverse defect: term officially approved by Canadian Pacific and CN.

English

Subject field(s)
  • Security Devices
DEF

A device that creates an image of a person’s naked body through their clothing to look for hidden objects without physically removing their clothes or making physical contact.

CONT

Full-body scanners are devices used in some airports to ensure that passengers are not carrying prohibited items aboard the aircraft. A passenger stands in front of the scanner with his/her arms extended over the head, with fingers touching. Security personnel review a digital image of the passenger and check for objects that are not permitted aboard the flight.

French

Domaine(s)
  • Dispositifs de sécurité
CONT

Certains aéroports utilisent le scanner corporel pour vérifier que les passagers ne transportent pas d'articles interdits à bord de l'avion. Le passager entre dans le scanner et s'y tient debout, gardant les bras au-dessus de la tête et se touchant le bout des doigts. Le personnel de sécurité examine l'image numérisée du passager pour vérifier qu'il ne transporte pas d'articles interdits.

Record 4 2005-12-19

English

Subject field(s)
  • Horse Racing and Equestrian Sports
CONT

... at rising trot you’ll spend half of your time in a full seat-balanced over your feet, with your legs AND your crotch and seatbones in contact with the horse. You’ll spend the other half of your time in a half-seat, with your crotch and seatbones OUT of the saddle. Rising to the trot means alternating rhythmically between full seat and half-seat(three-point and two-point).... Your half-seat will be easy if your stirrups are the correct length, and impossible if they aren’t-so DO check this before you begin! When you ride in a half-seat, your legs should be relaxed, KNEES BENT, your heels low, your head up with eyes looking forward, and your hands forward holding the mane or a neckstrap(essential to helping you learn to keep your balance without hurting your horse's mouth).

OBS

In Western riding, this means rising up out of the saddle with the weight in the stirrups. In English riding, the term may mean lightening the seat by pushing more weight down into the heel and slightly inclining the body forward (but not so far that the rider is in a two-point, or jumping, position), or a position used for the hand-gallop, a speed faster than canter.

Dirty play has always been a part of hockey and you have to battle through it and try to make the best of it.

CONT

"The initial check was fine--I haven’t seen the replay--but when he hit me the second time when I was on my knees, when he drove me head into the boards, I mean that's a dirty play, plain and simple. "

CONT

The key to Carleton’s improved play has been, depending on where your allegiance lies, aggressiveness (or "dirty" play). They make up in high sticks, interference and half-checks what they lack in playmaking and scoring ability.

English

Subject field(s)
  • Mechanical Transmission Systems
CONT

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.

French

Domaine(s)
  • Transmissions mécaniques
CONT

[...] 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.

... the loss of head is taken as a criterion, and washing is carried out as soon as it reaches a certain limit, incorrectly called maximum clogging. In fact, this loss of head depends on both clogging and flow. This method permits a check to be kept upon the clogging of the filter only if the flow is constant.

En réalité, cette perte de charge dépend à la fois de l'encrassement et du débit. Ce moyen ne permet d'apprécier l'encrassement du filtre que si l'on travaille à débit constant.
