Record 1 2012-04-23

English

Subject field(s)
  • Mountain Sports
DEF

The insertion of piton into a crack by means of a hammer or by hands.

CONT

In hard, solid rock select a crack wide enough to admit one third to one half of the piton shaft before driving the piton in. The placing of pitons in soft, rotten rock is often not practical. When this type of rock must be scaled, loose rock from the crack should be removed before setting the piton.

CONT

Many of the skills of piton placing can be gained only by practice, and once again an occasional hour spent experimenting with pegs on a boulder can give valuable knowledge.

CONT

Placing Pitons: The placement of pitons is normally the function of the leader ... Ideally, a piton should be inserted into a crack 1/2 to 2/3 of its length and driven hard to the hilt. A ringing sound, steadily increasing in pitch, usually indicates a solid piton.

OBS

Using pitons is known as "pegging" and taking them out is called "de-pegging". This English word is gradually replacing the French one in Britain.

French

Domaine(s)
  • Sports de montagne
DEF

Action d'enfoncer des pitons dans une paroi.

CONT

La solidité d'un piton n'est pas proportionnelle au nombre de coups de marteau, mais plus à la réflexion sur l'emplacement et le choix de celui-ci. Le son qu'émet le piton lors de la frappe est le meilleur des indices. Un son clair et aigu indique qu'il est solide. Si le pitonnage est très délicat ou si le choix des pitons est très limité, on utilise diverses astuces.

Record 3 - external organization data 2005-11-08

English

Subject field(s)
  • Physics
  • Nuclear Fission Reactors
  • Compartment - Canadian Nuclear Safety Commission
CONT

When a turbine comes to rest, after operating, the cooler denser steam tends to collect in the lower half of the cylinder and makes the lower half of the rotor cool quicker than the upper half. This causes the shaft to hog(bend upwards). When at rest and cool, the shaft will begin to sag under its own weight. If the turbine shaft is not rotated, hogging, especially above a critical temperature, can become permanent and the shaft would have to be sent to the manufacturer for heat treatment and straightening.

French

Domaine(s)
  • Physique
  • Réacteurs nucléaires de fission
  • Tiroir - Commission canadienne de sûreté nucléaire
CONT

Lors du ralentissement d'une turbine occasionné par un arrêt de production, la vapeur plus froide et plus dense s'accumule dans la moitié inférieure du boîtier. En conséquence, la moitié inférieure du rotor refroidit plus rapidement que sa partie supérieure ce qui cause un fléchissement vers le haut de l'axe de la turbine. Par contre, l'arbre d'une turbine au repos et refroidie commencera à s'affaisser sous son propre poids. À une température supérieure à un point critique, si l'on ne tourne pas l'arbre de la turbine, le fléchissement vers le haut pourra devenir permanent.

CONT

The spike at the other end of the shaft [of the ice axe] should be two and a half to three inches long and must have a square or rectangular-not round-cross-section.... The smoother the juncture at the metal ferrule which joins the handle and spike, the more easily the axe shaft can be thrust into hard-packed snow.

Record 5 2000-09-26

English

Subject field(s)
  • Continuous Handling
  • Underground Mining
  • Ore Extraction and Transport
DEF

The structure used in a mine shaft for the conveyance of men and materials.

CONT

The approximate weight of a steel cage is 1 1/2 times that of the coal it carries, or about equal to the weight of the coal and the mine cars. Cages are usually designed to take one or two cars per deck and may be single or multi-decked. Where multidecked cages are used, simultaneous or consecutive discharge of decks can be employed. The modern trend is towards consecutive decking with power-operated cage unloading equipment. Cages can be either steel, composite or all-alloy construction. An all-alloy cage is about half the weight of its all-steel equivalent. The cage is suspended from bridle chains which in turn are attached to the cappel of the winding rope. Normally there are two cages in simultaneous operation in the shaft and travelling in opposite directions.

CONT

According to Bengt Beckman the worlds first cryptomachine was swedish... The machine, called in 18th century swedish :"Chiffre-Machinen", consisted of 57 wheels mounted on a common shaft. These wheels were housed in an oblong cylinder. On half of the circumference of each wheel, the normal ordered alphabet was engraved, and on the other half numbers between 0 and 99 were likewise engraved, but in mixed order, with each of the 57 wheels having their own mixed sequence. On one side, along the length of the cylinder, was a slot wide enough to allow one letterposition of all the 57 wheels to be seen, and on the opposite side a similar slot allowed a row of 57 figures to show themselves.

CONT

Cipher devices and cipher machines ... range in complexity from simple rotating concentric disks ... to large machines and electrically operated cipher teleprinters.
