CONT

The watt-hour(symbol W·h or Wh) is a unit of energy. It is most commonly used on household electricity meters in the form of the kilowatt-hour(kW·h or kWh), which is 1, 000 watt-hours. It is not used in the International System of Units(SI), despite being based on the watt, as the hour is not a SI unit. The SI unit of energy is the joule(J), equal to one watt-second. It is, however, a commonly used unit, especially for measuring electric energy. 1 watt-hour is equivalent to 3, 600 joules(1 W x 3600 s), the joule being the canonical SI unit of energy. Thus a kilowatt-hour is 3, 600, 000 joules or 3. 6 megajoules.... The kilowatt-hour is commonly used for electrical and natural gas energy. Many electric utility companies use the kilowatt-hour for billing.

OBS

Megawatt-hours are used for metering of larger amounts of electrical energy. For example, a power plant’s daily output is likely to be measured in megawatt-hours.

OBS

plural: kilowatt-hours or kilowatthours. Lots of variants can be found, but they should be avoided: kilowattshours, kilowatts hour, kilowatts hours, kilowatt hours, kilowatts-hour, kilowatts-hours, kilowatts/hour, kilowatts/hours, kilowatt/hours.

A ... semipermanent anticyclone that has been said to overlie the ice caps of Greenland and Antarctica.

OBS

semi-permanent anticyclone: Region where high pressures largely predominate during a major portion of the year and for which an anticyclone appears on the mean monthly pressure charts.

OBS

As presented by W. H. Hobbs, it was thought that these [glacial] anticyclones played a dominant part in the world atmospheric circulation, but modern theory backed by limited observation has tended to diminish their importance and even to question their reality.

One... method of application akin to dipping is flooding on, where articles such as radiators and transformers, are suspended over a drain tray and hosed with paint pumped from a storage tank. The hose is manually operated, and hosing is continued until the article is completely covered. Surplus paint collecting in the drain tray is pumped back to the storage tank via a filter(Source of terms and context :W. H. Tatton and E. W. Drew : Industrial Paint Application, London, Nevones and Butterworth, 1971, pp. 18 and 263).

Le procédé par "ruissellement" ou "arrosage" est une variante des procédés au trempé classiques, utilisable pour des pièces volumineuses et fixes. C'est alors la pièce qui est arrosée par la peinture, qui s'écoule dans un bac où elle est recueillie et réutilisée. C'est un procédé rudimentaire appelé parfois procédé "à la casserole" car c'est en fait cet instrument qui sert à arroser la pièce.
