Visual-Accumulation-Tube Size Analyser : This method is suitable for simple and rapid analysis of the size frequency distribution of sand samples with particles between 62 microns and 2mm. The instrument operates on the principle of the fall velocity of particles and consists of a glass sedimentation tube, a valve mechanism and a recorder.  1, record 1, English, - visual%20accumulation%20method

Un mode opératoire très simple (méthode des béchers) a été mis au point par A. Avy et R. Raillères. Dans une colonne de liquide "h", on introduit un poids "p" de poudre, on agite pour rendre la suspension homogène, on laisse au repos un temps "t" (10 secondes par exemple) puis on décante. Si 10 secondes est le temps nécessaire pour que les particules de 10 [microns] tombent de la hauteur "h", le sédiment "S" renfermera toutes les particules de 10 [microns] et plus; (...)  1, record 1, French, - m%C3%A9thode%20des%20b%C3%A9chers

A type of pressure-tube anemometer, named after the inventor, in which the pressure head is located on the windward end of the wind vane so that it is kept facing into the wind.  3, record 3, English, - Dines%20anemometer

The Dines Pressure Tube Anemometer is universally recognised as the most reliable and accurate instrument of its kind and has been adopted as standard by the British Meteorological Office and by meteorological stations world-wide. Dines Pressure Tube Anemometer consists essentially of a Head Assembly, a Velocity Recorder and a Direction Recorder, the IM100 records wind speed and wind direction simultaneously on a single chart. An important feature of the Dines, is that it records not only average wind velocity over a given time, but also variations in wind force, with the strength and frequency of gusts, providing valuable data on the internal structure of the wind.  2, record 3, English, - Dines%20anemometer

The suction head is mounted concentrically with the shaft, near the bearing that supports the vane, and develops a suction that is independent of wind direction. The pressure difference between the suction head and the pressure head is proportional to the square root of the wind speed and is measured by a specially designed float manometer with a linear wind scale.  3, record 3, English, - Dines%20anemometer

The Dines anemometer was first described by William Henry Dines in 1892 and had all the essentials of the final form of the pressure-tube anemometer. With various modifications, the Dines anemometer remained a useful wind measuring device into the 1960s.  3, record 3, English, - Dines%20anemometer

Selon leur principe de fonctionnement, les capteurs de la vitesse ou/et de la direction du vent peuvent être classés en quatre catégories. Ainsi, on distingue ceux qui sont sensibles [...] à la pression du fluide : le tube de Pitot ou l'anémomètre de Dines (ancienne version du tube de Pitot, largement utilisée dans les années trente pour les observations météorologiques) [...]  3, record 3, French, - an%C3%A9mom%C3%A8tre%20de%20Dines

Cylindre de décantation. Principe: si on laisse sédimenter une suspension uniforme pendant "t" secondes et qu'ensuite on décante à une profondeur "h" centimètres, le liquide non décanté contient toutes les particules qui ont des vitesses de chute supérieures à "h/t", plus les particules de vitesse inférieure à "h/t" qu'il contenait déjà. (...) L'appareillage est fort simple. Un récipient de un litre environ, de hauteur 12,5cm muni d'un siphon à 25mm du fond, contient la suspension; la fraction qui doit être décantée est soutirée par siphon ou robinet.  1, record 4, French, - cylindre%20de%20d%C3%A9cantation
