HELICAL TUBE [13 records]

Record 1 2024-12-17

English

Subject field(s)
  • Medical Imaging
CONT

Helical Acquisition... In this approach, image acquisition time is decreased significantly by connecting the tube voltage cables through a "slip ring, "a sliding contact mounted on the rotating gantry of the unit. With slip-ring technology, the X-ray tube rotates while the patient table moves without stopping. Hence, the patient is moved continuously through the gantry during the study, and the X-ray beam maps out a helical path in the patient...

French

Domaine(s)
  • Imagerie médicale
CONT

Contrairement à l'acquisition séquentielle où la table d'examen reste fixe, l'acquisition hélicoïdale consiste à sélectionner un volume (point de départ et d'arrivée sur le corps à examiner) qui se déplace à vitesse constante sous le faisceau de rayons X «tournant» de manière continue.

Campo(s) temático(s)

CONT

La tomografía computarizada (TC) mediante adquisición helicoidal ofrece un análisis anatómico detallado multiplano de las estructuras nasales y sinusales, así como de las variaciones de neumatización que pueden modificar las relaciones sinusales.

DEF

A short helical auger incorporating a steel tube to help hold the cuttings on the auger during withdrawal from the drill hole.

OBS

auger: Any of various augerlike tools designed for boring holes in wood or for boring into soil and used especially for such purposes as mining coal, prospecting, drilling for oil or water, and digging postholes.

CONT

Il existe de nombreuses sortes de tarières, mais les plus courantes sont la tarière à godet et la tarière à vis. La tarière à godet normale est un cylindre métallique d'environ 16 cm de longueur et de 8 à 10 cm de diamètre. À l'extrémité inférieure, elle a un bord tranchant, qui lui permet de traverser très facilement la plupart des sols. Les tarières à godet sont presque toujours munies d'une tige coulissante et d'un manche qui permettent de prélever des échantillons à de plus grandes profondeurs, généralement jusqu'à 1,1 m. Un échantillon prélevé à la tarière à godet est légèrement perturbé, mais il est acceptable pour la plupart des usages et il est d'un volume suffisant pour d'ultérieures analyses de laboratoire.

OBS

tarière : Instrument qui sert à faire des forages, des sondages dans le sol.

Record 6 2004-09-23

English

Subject field(s)
  • Weather Stations and Meteorological Instruments and Equipment
DEF

Thermometer equipped with a device providing a continuous record of temperature.

CONT

A thermograph is a recording thermometer. Usually configured with a pen that records temperature on a revolving cylinder. The pen is at the end of a lever that is controlled by a bi-metal strip of temperature-sensitive metal which bends as the temperature changes.

OBS

The thermometric element is most commonly either a bimetal strip or a Bourdon tube filled with a liquid. In the first case the bimetal element has the form of a helical coil with one end rigidly fastened to the instrument and the other to the recording pen. In the second case the tube is made with an elliptical cross section so that an expression of the liquid caused by a temperature increase will cause the radius or curvature of the bend to increase, thus moving the instrument pen, which is fastened to the tip of the tube. A resistance thermometer and a thermoelectric thermometer may be converted into thermographs if provision is made to record their output.

French

Domaine(s)
  • Stations, instruments et équipements météorologiques
DEF

Thermomètre muni d'un dispositif qui enregistre continuellement la température.

CONT

[Le] thermographe [...] est utilisé pour enregistrer l'évolution des températures en fonction du temps. Le thermographe utilise en fait un bilame métallique dont l'une des extrémités est reliée à une pointe feutre qui inscrit les variations de température sur un diagramme, lui même enroulé sur un cylindre tournant, mû par un mouvement d'horlogerie.

CONT

A typical cyclone is illustrated in Figure 6 [p. 15]. Dust-laden gas tangentially enters the annular space between the cyclone body and the outlet tube, and begins to traverse a helical path(shown by the solid flow line) called the "main vortex". Near the bottom of the cone, the axial direction of the helix reverses, as shown by the dotted line, and forms the "vortex core". The tangential velocity is greatest at a radial distance from the centerline of 0. 4 to 0. 8 the radius of the gas outlet tube. The diameter of the vortex core is usually 0. 2 to 0. 4 times the diameter of the gas outlet. The tangential direction of flow is the same in both the main vortex and the vortex core, so that centrifugal separating forces are exerted on the particles in both sections of flow.
