IMPULSE MACHINE [5 records]

Record 1 2025-09-25

English

Subject field(s)
  • Ultrasonography
  • Acoustics (Physics)
  • Morphology and General Physiology
CONT

Point shear wave elastography(pSWE) [is] dependent on the dynamic stress [of acoustic radiation force impulse, and] focuses on a single focal location... pSWE utilizes B-mode [brightness mode] ultrasound to directly visualize and select the region of interest... pSWE can easily be performed on a conventional ultrasound machine... with no need for any special probe or machinery, but it does not have the ability to showcase images of tissue stiffness.

Key term(s)
  • point shearwave elastography

French

Domaine(s)
  • Ultrasonographie
  • Acoustique (Physique)
  • Morphologie et physiologie générale
CONT

Dans le cas de l'élastographie par ondes de cisaillement ponctuelles (pSWE) [...], une force de radiation acoustique (ARFI) est utilisée pour générer les ondes de cisaillement.

Record 2 1993-12-21

English

Subject field(s)
  • Paper Manufacturing Processes
DEF

A method for rapid drying of paper using a simultaneous mix of pressing and drying processes, usually involving high nip loadings (dryer drum nips with a special roll).

CONT

Electrical impulse drying.... The water is removed through the application of instant heat and pressure/which forces the water from the paper web/on the paper machine. The water on the surface of the web "flashes"/to steam/because of the heated roll and then propels the liquid water from within the web/into the felt.

French

Domaine(s)
  • Fabrication du papier
OBS

Record 3 1987-06-04

English

Subject field(s)
  • Steam Turbines
  • Hydraulic Turbines
CONT

Another steam-driven machine... used a jet of steam impinging on blades projecting from a wheel causing it to rotate. This machine operated on the impulse principle.

French

Domaine(s)
  • Turbines à vapeur
  • Turbines hydrauliques
CONT

Comme l'eau dans les turbines hydrauliques, la vapeur peut agir uniquement par sa force vive sur les aubes de la roue mobile d'une turbine, qui fonctionne alors par action.

Record 4 1986-06-27

English

Subject field(s)
  • Turbines
  • Energy Transformation
  • Geophysics
CONT

If a reaction turbine were used instead of an impulse machine the trouble would remain; for a high nozzle efficiency would mean that a blade speed suited to the steam velocity would be too high for the water velocity....
