PITCH INCREASE [10 records]

Record 1 2016-02-29

English

Subject field(s)
  • Audiovisual Techniques and Equipment
  • Telecommunications
DEF

An electronic device capable of compression and expansion of an audio signal(usually human speech) without corresponding increase or decrease in the pitch. Compressors may be built into audiotape recorders and may be of variable or fixed rate.

French

Domaine(s)

Record 2 2014-10-21

English

Subject field(s)
  • Aircraft Piloting and Navigation
  • Aircraft Propulsion Systems
DEF

The acute angle between the no-lift direction and the plane normal to the hub axis.

OBS

Pitch is not the same as blade angle, but, because pitch is largely determined by blade angle, the two terms are often used interchangeably. An increase or decrease in one is usually associated with an increase or decrease in the other.

OBS

The usual symbol for blade angle is the Greek letter beta.

French

Domaine(s)
  • Pilotage et navigation aérienne
  • Propulsion des aéronefs
DEF

Angle formé par la corde d'un profil [de pale] et le plan de rotation de l'hélice.

Spanish

Campo(s) temático(s)
  • Pilotaje y navegación aérea
  • Sistemas de propulsión de aeronaves

Record 3 2013-06-26

English

Subject field(s)
  • Electric Rotary Machines - Types
  • Wind Energy
DEF

[A horizontal axis wind turbine] where the global pitch angle [of the blades] does not change dynamically ...

CONT

Pitch Regulation. Once the rated wind speed has been reached, a WT [wind turbine] will be unable to make use of all of the wind energy incident on the rotor plane and must shed some. A pitch-regulated WT [wind turbine] will do this [namely] by pitching the blades to increase the angle of attack to cause sections of the blade to stall(in pitch-to-stall machines).

French

Domaine(s)
  • Machines tournantes électriques - types
  • Énergie éolienne
DEF

Éolienne à axe horizontal dont le rotor est muni de pales fixées de manière rigide au moyeu et qui est régulée soit par effacement du rotor, soit par décrochage aérodynamique passif des pales.

Record 4 2000-09-19

English

Subject field(s)
  • Orthopedic Surgery
CONT

The exact mechanism by which calcaneal lengthening corrects valgus deformity is not entirely known. It has been shown that a 1-cm lengthening of the calcaneus by the Evans technique results in an increase in the anteroposterior and lateral talometatarsal angle, calcaneal pitch, and talonavicular coverage.

Record 5 1996-12-19

English

Subject field(s)
  • Trucking (Road Transport)
  • Trailers and Hauling
  • Braking Systems (Motor Vehicles and Bicycles)
DEF

Spiral-shaped trailer brake hose equipped with a gladhand, which connects the brake lines between two road vehicles.

OBS

Rubber lines, which require a brake hose support to allow free movement, are being gradually replaced by coiled plastic trailer hoses(whose freedom of movement is automatically ensured by an increase in the pitch between coil turns).

French

Domaine(s)
  • Camionnage
  • Remorques et remorquage
  • Freins (Véhicules automobiles et bicyclettes)
DEF

Flexible de liaison enroulé en spirale et muni d'une tête d'accouplement, assurant la liaison de freinage entre deux véhicules routiers.

OBS

Aux canalisations en caoutchouc, qui nécessitaient une potence pour permettre leur débattement, se substituent de plus en plus ces serpentins en forme de solénoïde réalisés en matière plastique, dont le débattement est assuré automatiquement par l'allongement du pas entre les spires.

Spanish

Campo(s) temático(s)
  • Transporte por camión
  • Camiones con remolque y remolque
  • Frenos (Vehículos automotores y bicicletas)
DEF

Tubo flexible en espiral con conector que se usa como línea de transmisión del freno neumático entre dos partes de un camión tractor.

OBS

Estos tubos plásticos en forma de solenoide se emplean cada vez más para reemplazar las mangueras de goma, puesto que ajustan automáticamente el espacio entre la carrocería y el eje con la separación de las vueltas, lo que sólo se logra con una potenza o ménsula en el caso de las mangueras de goma.

Record 6 1991-02-15

English

Subject field(s)
  • Cooling and Ventilating Systems
CONT

Fan Blade Pitch Variation. Vaneaxial fans are available with adjustable pitch blades to permit varying the fan's performance. This may be used to increase or decrease system capacity on direct drive fans, depending upon the original selection.... One method of fan-blade pitch variation allows for a change in pitch while the fan is in operation.

CONT

Vaneaxial fans are available with adjustable pitch blades to permit varying the fan's performance. This may be used to increase or decrease system capacity on direct drive fans, depending upon the original selection.

CONT

Variable-pitch blades for axial fans can be controlled to reduce flow and power by changing the angle that the blades deviate from the axis of the shaft.

French

Domaine(s)
  • Systèmes de refroidissement et de ventilation
CONT

Les ventilateurs axiaux à pales à pas variables peuvent réduire le débit et la puissance en changeant l'angle entre les pales et l'axe de la roue.

CONT

Ventilateur à pales ajustables; ventilateur à pales non ajustables.

OBS

Régulation par pas variable.

English

Subject field(s)
  • Cooling and Ventilating Systems
CONT

Vaneaxial fans are available with adjustable pitch blades to permit varying the fan's performance.... On belt-driven fans it may allow some increase in efficiency if the static pressure was grossly over-estimated when the original selection was made.

French
