Subject field(s)
  • Doors, Windows and Openings (Building Elements)
CONT

Thermal windows are special energy efficient windows that are designed to slow the passage of heat. Thermal windows have 2-3 panes, and many of them have non-toxic gasses between the panes. Others will have special glass that blocks UV [ulraviolet] heat from the sun. Together, the panes, gas, and special glass slow heat from passing.... In summer, thermal windows block hot outside air from entering your air conditioned home. In winter, they stop heated air from escaping.

French

Domaine(s)
  • Ouvertures (Éléments du bâtiment)
CONT

Les fenêtres thermos, parfois appelées fenêtres à vitrage thermique, sont des fenêtres composées de plusieurs panneaux de verre écoénergétique haute performance, ce qui les rend plus écoénergétiques que les fenêtres à simple vitrage standard. [...] Les fenêtres thermos ont des panneaux de verre séparés par un espace isolé rempli de gaz. Ce gaz isolant réduit la quantité de chaleur transférée entre l'intérieur et l'extérieur de votre maison ou de votre entreprise. Pendant les mois chauds d'été, les fenêtres thermos isolées empêcheront une grande partie de la chaleur extérieure d'entrer dans la maison et pendant les mois d'hiver, moins de chaleur de l'intérieur de la maison sera évacuée vers l'extérieur.

CONT

En plus du gaz isolant entre plusieurs vitres, les fenêtres thermiques intègrent du verre écoénergétique. Le verre à faible émissivité écoénergétique contribue à améliorer encore l'efficacité énergétique des fenêtres en bloquant la lumière UV [ultraviolette] génératrice de chaleur tout en laissant passer la lumière visible.

English

Subject field(s)
  • Effects of Pollution
  • Climate Change
CONT

"Greenhouse gases" in the atmosphere block infrared radiation from escaping directly from the surface to space. Infrared radiation cannot pass straight through the air like visible light. Instead, most departing energy is carried away from the surface by air currents, eventually escaping to space from altitudes above the thickest layers of the greenhouse gas blanket.

French

Domaine(s)
  • Effets de la pollution
  • Changements climatiques
CONT

«Les gaz à effet de serre» présents dans l'atmosphère empêchent les rayonnements infrarouges d'être renvoyés de la Terre vers l'espace. Les rayonnements infrarouges ne peuvent traverser directement l'atmosphère comme la lumière visible. En fait, la plus grande partie de l'énergie qui parvient à s'échapper est emportée par les courants aériens et se perd finalement dans l'espace à des altitudes supérieures aux couches les plus épaisses de la couverture de gaz à effet de serre.

Record 5 2011-05-31

English

Subject field(s)
  • Analytical Chemistry
OBS

Two main types of sample splitter are in common use, known as calibrated lead devices, and dividing valves. Most of these are based upon the principle that the head of the capillary column constitutes only a small proportion of the total outlet from the sample injection block. As the carrier gas enters the block it carries a small amount of the sample into the capillary column while the remainder is vented away through a larger opening. This can be done by having the capillary column held at the axis of a circular hole in the injection block, or by having it forming a narrow arm of a T-or Y-piece at the column head. In either case the amount going into the capillary column can often be further regulated by means of a tapered needle control.

Subject field(s)
  • Lighting
DEF

A type of lighting that utilizes light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs), or polymer light-emitting diodes as sources of illumination rather than electrical filaments or gas.

OBS

The term "solid state" refers to the fact that light in an LED is emitted from a solid object(a block of semiconductor) rather than from a vacuum or gas tube, as is the case in traditional incandescent light bulbs and fluorescent lamps. Unlike traditional lighting, however, SSL creates visible light with virtually no heat or parasitic energy dissipation. In addition, its solid-state nature provides for greater resistance to shock, vibration, and wear, thereby increasing its lifespan significantly.

CONT

The GDS [Gas Delivery System] is a 4-PU passive drawer. There are no rack data or power connections. The drawer will contain a Dapco-sealed Minicel foam block wrapped in beta cloth capable of storing up to five bottles of calibration and/or respiratory gas mixtures. The drawer includes 2 Lexan plates that will be attached to the internal surface of the drawer side panels. The Lexan plates will center the foam block in the drawer and have grooves that allow the bottle retention plate(guillotine) to slide in perpendicular to the Lexan plates in 2 locations. The guillotine is placed in front of the bottles for launch and landing and placed behind the bottles for operation.

English

Subject field(s)
  • Burners and Steamfitting
DEF

A gas burner in which the actual combustion begins in a refractory tunnel or tuyere block. It is a relatively high capacity partial-premix type of gun burner, which uses the kinetic energy of the gas stream issuing from the orifice to bring in at least part of the air required for combustion. A wide range of control of flame characteristics is obtained by adjustment of the primary air, thus causing combustion to be delayed until secondary air can reach the air-fuel mixture.

CONT

Brûleur à «tunnel de flamme». C'est un appareil de conception anglaise spécialement étudié pour l'équipement des fours industriels [...] mais il pourrait tout aussi bien être placé sur des générateurs de vapeur ou sur des chaudières de chauffage central [...] Compte tenu du fait qu'une grande partie de la combustion se produit dans la préchambre C (environ 40 %), il est facile de calculer que son «intensité» correspond à près de 1 000 kg/h. m³ [...] La flamme sortant de C à environ 40 m/s est courte, extrêmement dure et généralement bleue; [...]

CONT
