The distributer, B, is so arranged as to cause the water, and oil, and the liquids to be vaporized to flow with the greatest regularity, and proportionally to the consumption of the gas in cases where the latter is not stored up in a gas meter. The flow is controlled by cocks that are actuated by variations in the height of the regulator receiver. All the condensation that occurs in the various parts of the apparatus collects in a receptacle, 52, so arranged as to perform the office of a separator and set apart the oil at 20, and the water at 21, through the natural effect of their difference in density. This latter is likewise utilized for causing the oil to flow into the vaporizer through 26 and 27, instead of using a graduated cock that receives a variable pressure from the receiver. In this way every cause of obstruction is avoided. [Illustration: FIG. 2.--SECTION.] We have stated that the regulator, C, serves to automatically regulate the flow of the liquids proportionally to the consumption of the gases produced. To effect this a communication is established between the regulator receiver, 59, and the aperture through which the liquids flow, and the flow is thus modified by the valves, 54 and 55. The water contained in the reservoir of the regulator serves to wash the gas which enters through a number of orifices in the disk, 60, this latter being fixed beneath the level of the water. The gas may be purified by dissolving metallic salts in the water. By means of the arrangement above described, there may be manufactured at will a rich gas from liquid hydrocarburets, hydrogen from water, and gas obtained by an admixture of two others simultaneously produced and combined in the apparatus.--_Chronique Industrielle._ * * * * * SUGAR NITRO-GLYCERINE.
