Abstract: Poêle (1) comprenant un foyer (4) et un compartiment à cendres (5) séparés par une grille (19). Un moyen d'admission d'air (21, 23) se trouve au-dessous du compartiment à cendres. Un moyen d'alimentation en air (30) relié au moyen d'admission d'air s'étend verticalement au-delà du compartiment à cendre vers une région supérieure dudit foyer. Un moyen de circulation d'air (27) crée une communication entre le moyen d'alimentation en air et le foyer. En utilisation, le combustible brûlant à l'intérieur du foyer provoque l'aspiration de l'air extérieur dans le moyen d'admission d'air et son passage dans le moyen d'alimentation en air et dans le moyen de circulation d'air vers une région située au-dessus du combustible du foyer. L'air extérieur est préchauffé par son passage au-dessous du compartiment à cendres et au-delà dudit compartiment et du foyer pendant qu'il pénètre dans ledit foyer. La turbulence provoquée par l'interaction s'effectuant entre l'air préchauffé pénétrant dans le foyer et l'air chaud déjà présent crée l'expulsion de l'air de combustion contenant de la fumée (F) par une porte (35) située à l'avant dudit foyer.

Abstract: L'invention se rapporte à la préparation d'unités de nucléotides et de nucléosides destinées à la synthèse d'ARN et d'ADN. La préparation du reste de sucre deutérisé est également décrite. Les unités deutérisées sont utilisées pour synthétiser des brins d'ARN et d'ADN, une unité n'étant pas deutérisée alors que des unités adjacentes le sont. La deutérisation est suffisamment élévée pour que la résonance à partir des unités deutérisées ne recouvre pas les résonances provenant des unités non deutérisées au cours d'expériences relatives à la résonance magnétique nucléaire (TMN). Une fenêtre de 'RMN' est ainsi créée dans les brins d'ADN ou d'ARN, laquelle peut être utilisée de manière avantageuse pour des études avancées de la structure par rapport à l'activité biologique dans l'ADN et l'ARN.

Abstract: A process for producing aluminum hydroxide from an alumina-containing ore by extracting alumina with an aqueous alkali solution from the ore, which process comprises feeding a high-concentration alumina-containing ore slurry which has been prepared by using a small amount of an aqueous alkali solution and an aqueous alkali solution which has been preheated in such a manner that the temperature of the slurry after being mixed with the alkali solution exceeds the temperature for extracting alumina to an extractor composed of tubular reactors at the same time or after the slurry is mixed with the alkali solution, extracting alumina from the ore under the extracting conditions of 120 to 160°C and ten minutes or less, removing immediately thereafter a dissolution residue from a liquid extract, desilicating the extract, and adding seed aluminum hydroxide to the desilicated extract to thereby deposit aluminum hydroxide. The process enables aluminum hydroxide reduced in the possibility of pollution caused by silica to be economically produced even from an alumina-containing ore with a high reactive silica content.

Abstract: A liquid crystal light valve (12) is sequentially modulated with images corresponding to three primary color components of a scene at a rate which is faster than flicker can be perceived. A color switching apparatus (20) receives a white light beam from a high intensity light source (18), separates the white light beam into three color light beams of the respective primary colors, and sequentially illuminates the light valve (12) with the three color light beams in synchronism with modulation of the light valve (12) with the corresponding color image components. An optical system (26) projects an image of the modulated light valve surface on a screen (28), such that the three color component images appear to merge together in time and thereby synthesize a full color image of the scene. The switching apparatus (20) includes a polarizing beam splitter (30), three dichroic reflectors (34,36,46) which separate the white light beam into the three color light beams, and electrically switchable polarization rotators (38,40,48). The rotators (36,40,48), in combination with the beam splitter (30), control the polarizations of the color light beams such that only a selected one of the beams is directed to an output with a predetermined polarization suitable for illumination of the light valve (12), and the other two colors are effectively switched off.

Abstract: A pressure compensation device for use in a high-pressure direct driven pump to control the output pressure of the pump is shown and described. In a preferred embodiment, the high-pressure pump has a valve assembly that selectively allows fluid pressurized by a reciprocating plunger to pass from a pressurization chamber to an outlet chamber from which the pressurized fluid is collected for use. A pressure compensation device has a lever which balances a control force against a force generated by the high-pressure fluid in the outlet chamber. When the outlet pressure exceeds a selected level, the pressure compensation device acts to prevent the further pressurization of fluid by causing the fluid to flow back out of the pressurization chamber via the same passageway(s) through which the fluid was originally introduced into the system.
