Title: Automatic Infrared Analyzing Method of Blast Furnace Gases.
IPC: G01N21/35
Filed: 1967-03-23
Abstract: 1,177,535. Infrared gas analyzers. NIPPON KOKAN K.K. March 23, 1967 [March 31 1966], No.13745/67. Heading G1A. The amounts of carbon monoxide and carbon dioxide in the gases issuing from a blast furnace are monitored by photo-electric gas analyzers using infrared radiation. Various procedures are carried out to reduce errors in the measurements so that the latter may be used to provide reliable input information for a computer controlling the blast furnace operation. The analyzers 12, 13 for the two gases are virtually identical. That for carbon monoxide comprises a source 14 of infrared radiation, a flow cell 15 for passage of the gas flow under investigation and a detector 17, feeding the circuit units shown in Fig. 1. The outputs of both analyzers are amplified at 24 and applied to an indicator 26 which provides an input to the computer. Other inputs to the computer are from a hydrogen analyzer 11 and a barometer-transducer system 33, 34, measuring the atmospheric pressure. The various procedures designed to keep errors in the measurements as low as possible are as follows. Firstly, the moisture content of the sample of blast furnace gas has to be maintained at a low and constant level. To do this, a sample of blast furnace gases, led off from cooling and washing tower 1 through pipe 5, and filtered of fine dust by glass wool in filter 8, is passed through the demoistener 10. The latter operates by cooling the gases to just above the freezing point of water using ethylene glycol cooling fluid. To avoid excessive reduction of the moisture content, the gases are first passed through a tank 38 of a saturated aqueous solution of carbon dioxide which has no effect on the carbon dioxide content but causes saturation of the gases with water. The indicator 26 for the analyzers may be calibrated beforehand using a standard gas mixture of known composition and known moisture content. Secondly, the analyzers 12 and 13 are kept at a constant temperature within enclosure 36. Thirdly, any leaking gas, which could interfere with the accuracy of the measurement if it moves into the spaces between the source and detector, is purged from the apparatus by clean air at the temperature of the enclosure. Fourthly, the gas in the flow cell is kept at atmospheric pressure by using a wide outlet pipe. Fifthly, measurements are corrected for changes in atmospheric pressure sensed by the barometer, before input to the computer.

[Classes 83 (i) and 83 (ii).] Casting-machines ; moulds.-In a process and machine for producing bearings for internalcombustion engines, a shell or backing of durable metal such as steel is lined with bronze or other soft bearing metal by heating the shell in a furnace, introducing molten bearing metal into the shell, cooling the shell rapidly, and rotating the shell about its axis until the bearing metal has set. A high frequency coil is mounted between the inner and outer walls b, a of a furnace and the tubular shell d is rotated therein by means of an electric motor g or otherwise. After heating, hydrogen or other reducing gas may be introduced into the furnace or projected into the shell by a nozzle (not shown), or borax solution may be flushed through the tube to remove oxide therefrom. Molten bearing metal is then introduced into the shell by pouring, or through a duct (not shown). The molten metal may be retained by flanges h or by rings attached to the ends of the shell. The speed of rotation of the shell is such as to produce a coating of bearing metal of uniform thickness and is continued after the heating has been stopped and until the metal has set. The shell may be cooled rapidly by projecting cold air or water onto the exterior surface by means of a pipe i and nozzles and the interior surface may also have air or water projected thereon. After removal from the furnace the shell is cut in lengths to form bushings or alternatively it may be cut into segments or helical strips which can be bent to semi-circular shape to form half-bearings. The furnace may be arranged vertically instead of horizontally as shown, and the bushing may be connected to the driving mechanism by means other than the chuck e.
