Semi-conductors are usually mixtures of oxydes which have been "doped" by small concentrations of certain elements, usually a rare earth. Their electrical conductivity when heated(by a platinum-rhodium wire) is altered appreciably by the presence of small concentrations of flammable and certain toxic gases.... The resistance of a semi-conductor gas detector is measured by small electrodes...  1, record 1, English, - semi%2Dconductor%20gas%20detector

La RTC vient de lancer sous le nom de Gazistance un composant destiné à la détection des gaz inflammables. Elle met en œuvre pour cela des céramiques semiconductrices (des oxydes ferriques, d'étain et de zinc) dont la variation de résistivité est fonction de la concentration de gaz ou de vapeurs dans l'air ambiant.  1, record 1, French, - Gazistance

Hydrargyrum medium-arc iodide, or HMI®, is a mercury-halide gas discharge medium arc-length lamp with a multi-line spectra emission. The name implies that hydrargyrum, an archaic term for Mercury(Hg), is held as a vapour mixed with other rare halides in a quartz-glass envelope with two tungsten-coated electrodes of medium arc separation. Unlike traditional tungsten lighting units, HMI(R) s use ballasts to regulate and supply electricity to the lamp head via a header cable. The lamp operates not by heating a tungsten-based filament, but rather by creating an electrical arc between two electrodes within the bulb that excites the pressurized mercury vapour and provides phenomenal light output with greater efficiency than tungsten-based lighting units.  3, record 2, English, - hydrargyrum%20medium%2Darc%20iodide%20technology

History: In the late 1960s German television producers sought out lamp developer OSRAM to create a less expensive replacement for incandescent lights for the film industry.

Une lampe aux halogénures métalliques ou lampe à décharge à haute pression est une lampe très utilisée pour l'éclairage lors de la prise de vue au cinéma, ainsi que dans les vidéoprojecteurs de forte puissance. Moins courantes en éclairage théâtral, elles envahissent l'éclairage public car leur couleur plaît. On les utilise surtout pour les terrains sportifs, comme les terrains de tennis, badminton, football, hockey, etc. Elles sont aussi très utilisées dans les gymnases et [les] terrains intérieurs. On peut également s'en servir pour éclairer les stationnements, les chantiers de construction et même les routes, en particulier les ponts. Certaines d'entre elles sont connues sous le nom de HMI, acronyme de l'expression allemande «Hydrargyrum mittlere bogenlänge Iod» (traduit en anglais par : «Hydrargyrum medium-arc iodide»), marque déposée de la firme allemande Osram, mais d'autres dénominations existent pour cette même catégorie de lampes, chez Osram (HMP, HTI, HSR par exemple) et chez d'autres constructeurs (MSR, MSD, MSI chez Philips).  3, record 2, French, - technologie%20HMI

noble: In chemical terminology this term describes an element which either is completely unreactive or reacts only to a limited extent with other elements. Six noble gases constitute a group in the Periodic Table that is variously called the zero group (as the first three of its members have a valence of zero), the inert gas group, and the noble gas group. The last is preferable, as three of the gases, through unreactive, are not inert.  3, record 4, English, - noble%20gas
