    摘要: A gas generator for air bags having a container holding a combustible gas mixture and fitted with a closure which opens into a combustion chamber fitted with a gas outlet in which the gas mixture is ignited by an ignition device. To provide a fast-reacting ignition device and generate a controllable flow of pressurized gas at a relatively low temperature, the container is mainly filled with a pressurized inert gas and contains 0.1 to 2.0% vol. of a hydrocarbon and 0.5 to 10% vol. of a gaseous oxidizing agent. On being actuated, the ignition device opens the container closure, ignites the gas mixture flowing into the combustion chamber and maintains combustion by the continuous supply of energy.

    摘要: This invention relates to methods of and apparatus for treating waste products. The apparatus comprises a furnace 1 and a recuperator 2, the furnace comprising at least one rotary section 4 for combustion and/or pyrolysis of the waste products and a stationary section 3 for guiding the smokes generated in the furnace between said rotary section 4 and the recuperator 2. This latter comprises an arrangement 11 -12 for causing the smokes to flow in a state of heat exchange with a fluid 14 for exploitation of the heat thus recovered. A heat-carrier fluid circuit is also incorporated between the walls delimiting the said stationary section 3 and/or the said rotary section 4 of the furnace and the recuperator 2, in such manner that the heat-carrier fluid may transfer the heat it had absorbed during its passage within the furnace walls to the exploitation fluid in the recuperator.

    摘要: The cooling of molten metal, such as metal continuously cast into an ingot mold, is retarded by establishing on the upper surface of the metal in the mold, a layer of cryogenic liquid such as nitrogen, helium or argon, with a finely divided material in homogeneous and stable suspension in the liquid. The finely divided material is in the form of particles having a size between 200 and 2,000 A and is present in a quantity between 10 and 1,000 grams per liter of cryogenic liquid. The suspended material may be aluminum, titanium, zirconium, niobium, calcium, lithium, magnesium, solid glass, or an oxide of aluminum, titanium, zirconium, niobium, calcium, lithium or magnesium, and is highly reflective to infrared radiation from the metal so as to reduce the transparency of the cryogenic liquid to this infrared radiation.

    摘要: A solution of hydride in liquid nitrogen, the hydride being one that is in gaseous phase at atmospheric pressure and ambient temperature. The concentration of hydride in the liquid nitrogen is comprised between 0.05 and 10 mol %, preferably between 0.05 and 2 mol %, and more preferably between 0.1 and 0.3 mol %. The hydride is selected from the group consisting of arsine, germane, phosphine (PH.sub.3), diborane and silane (SiH.sub.4) and is preferably silane. Atmospheres prepared from these solutions are useful in the thermal treatment of metals, or for surface treatment, particularly of polymeric or metallic surfaces.

    摘要: A high-speed jet of liquid oxygen (21) with a speed higher than 100 meters per second is delivered into the tuyeres of a blast furnace of cupola furnace together with pulverised carbon. The jet reaches the opposite wall of the cavity (9) formed at the outlet of the tuyere (6) in the mass of material contained in the shaft. Supplying oxygen to the bottom of the cavity improves the burning of the remaining coal, whereby higher injection levels may be achieved. The shape of the cavity may also be altered, and, in particular, faster reactions may be achieved in the axial region of the shaft.
