Record 2 2011-08-05

English

Subject field(s)
  • Dams and Causeways
DEF

A crest gate the face of which is a section of cylinder that rotates about a horizontal axis downstream from the gate.

CONT

The spillway is part of the central section of the main dam. It has six gated bays, each 50 feet wide. Six radial arm gates (tainter gates) control spillway discharge. Each radial arm gate is 50 feet wide by 25.24 feet high.

OBS

The water pressure against the gate is concentrated in the axis; this arrangement reduces friction in raising and lowering the gate. A seal is placed along the sides and bottom of the gate face for watertightness. The gate is raised and lowered by winches or hoists attached to cables or chains fastened to the bottom edge of the gate and lying against its water face; this allows a vertical lifting force to be applied. It can be closed under its own weight.

OBS

tainter gate: formerly called canal lock.

French

Domaine(s)
  • Barrages et chaussées
DEF

Vanne constituée d'une structure métallique profilée maintenue par un puissant bras articulé, généralement en aval, dont l'ouverture se fait par élévation.

Record 4 2010-01-28

English

Subject field(s)
  • Television (Radioelectricity)
CONT

The horizontal and vertical sync pulses that form part of the composite video signal are separated in the sync separator. The composite video signal is either taken from the video detector output or after one stage of video amplification. A sync separator is a clipper that is suitably biased to produce output, only during sync pulse amplitude of the video signal. In some receivers, a noise gate precedes the sync separator. This suppresses strong noise pulses if present in the video signal.

English

Subject field(s)
  • Civil Engineering
  • Transport of Water (Water Supply)
DEF

A gate with a flap suspended from a free swinging horizontal hinge, normally placed at the end of a conduit discharging into a body of water having a fluctuating surface elevation. The gate is usually closed because of external hydraulic pressure, but will open when the internal head is sufficient to overcome the external pressure, the weight of the flap, and the friction of the hinge.

French

Domaine(s)
  • Génie civil
  • Adduction d'eau (Alimentation en eau)
DEF

Ouverture par laquelle l'eau peut couler librement en direction de la mer, mais qui se ferme automatiquement pour empêcher l'eau de mer de couler dans la direction contraire.
