    摘要: Transfer line for cryogenic fluid comprising a transfer conduit (1) for cryogenic fluid and a conduit (3) for cooling fluid surrounded by a metallic shield (4) coupled thermally to the cooling conduit (3). The metal shield (4) is a thin strip wound in unsecured manner about the conduits (1, 3) and locally connected to the cooling conduit (3) by resilient clips (5) or by a layer (6) of connecting material. The metallic strip has a thickness no greater than 0.1 mm and can be of aluminum.

    摘要: The line of gas to be analyzed, the "zero" gas line and calibration gas line are each provided with a restriction operating in sonic rate supplying a nominal constant flow and downstream, have a discharge duct provided with a flow regulator. The nominal flows in the first and second lines are higher than the given flow supplied to the analyzer so that during each of the calibration and analysis steps, the whole of the circuit portion of the device is permanently flushed with the nominal gas of the line and/or by a portion of the recirculated flow of gas originating from another line.

    摘要: The process comprises the steps of mounting two rotary furnaces in series including a smelting station and a charge preheating station, effecting a smelting in the furnace at the smelting station while causing the fumes from the first furnace to pass through the furnace at the preheating station towards an exhaust chimney to preheat the charge in the preheating furnace, and transferring the furnace which is at the smelting station towards a casting station. To enable the various transfers of furnaces each furnace is associated with a transfer support including a device for causing rotation of the furnace.

    摘要: A process for refining pig iron from below the surface of a molten metal bath, and the resulting product, in which an oxidizing gas is injected in the bath and, during the last refining stage, a mixture of oxidizing gas and inert gas is further injected. The inert gas content x of the mixture is made to vary according to a law corresponding to an oxidizing gas dilution curve that is located in an area determined by two envelope curves, to wit, a first maximum dilution curve defined by the straight line portions:x=-766.7 %C+168.7 for 0.16

    摘要: To remove a layer of thermoplastic material, particularly of polyethylene, adhering to a substrate, particularly a strip of aluminum, there is directed against a region of the layer of thermoplastic material (2) a shaped jet (10) of hot inert gas, containing for example principally helium, to melt the thermoplastic material and the jet is displaced relative to the coated substrate to push back (11) the melted thermoplastic material. The gas or the gaseous between 300.degree. C. and 700.degree. C., by an electric resistance (20), adjacent the ejection nozzle (4).
