Abstract: PROBLEM TO BE SOLVED: To obtain a plated steel sheet in which the lubrication between the steel sheet and a die is improved and which has satisfactory press formability, particularly continuous press formability by controlling the strain of the amplitude probability density distribution of the cross-sectional curve in the surface of a plated steel sheet defined by the specific relation between the three- dimensional moment of amplitude probability density and the standard deviation of the amplitude probability density to a specified range. SOLUTION: The strain S of the amplitude probability density of the cross-sectional curve in the surface of a plated steel sheet defined by the strain: S=μ3/σ3 is controlled to >=-1.5 to <-0.3. In this way, its slidability is improved, where μ3: the three-dimensional moment of the amplitude probability density, and σ: the standard deviation of the amplitude probability density. The strain S of the amplitude probability density distribution is the standard showing the assymmetry of histrogram in statistics. Moreover, by controlling the X-ray diffraction intensity ratio D between the ζ phase and the δ1 phase on the topmost surface in the plating layer of the plated steel sheet expressed by formula to <=0.01, its slidability is furthermore improved.

Abstract: PURPOSE: To make the rate of reaction faster and prevent side reaction by letting the whole or part of the product of reaction of the fluid having passed through the catalyst layer formed around porous hollow fibers of glass or ceramic permeate into the hollow fibers.  
     CONSTITUTION: A multiplicity of porous hollow fibers 3 of glass or ceramic of outside diameter 2mm or less are bundled to provide the separation system, and the layer of catalysts 16 is formed around the hollow fibers 3. The raw fluid introduced along the arrow A is received from conduit 2 and is distributed in the direction orthogonal to the bundle of the hollow fibers 3 by a porous (or net-form) distributing pipe. This raw fluid reacts by contacting the catalysts 16 and the fluid formed of relatively small molecules permeates through the walls of the fibers 3 and moves into the hollow inside, is gathered by a receiving tray 6 and is recovered in the arrow C' direction. The large molecule fluid is gathered in the arrow B direction from the spacing between the outside peripheral surface of the securing part 4a and the inside peripheral surface of the vessel 5. Since the product of reaction by the catalyst 16 is promptly separated by the fibers 3 of large surface areas, the equilibrium of reaction moves and the rate of reaction increased.

Title: Heating tube of economizer in contact type sulfuric acid manufacturing apparatus

IPC: C01B17/80
Filed: 1978-03-09
Abstract: PURPOSE: To avoid dewing of sulfuric acid and prevent corrosion of fins and heating tubes by putting a tube of small size into each heating tube in the vicinity of a SO 3 -contg. gas outlet out of the boiler feed water heating finned tubes of an economizer incorporated in a contact type sulfuric acid manufacturing apparatus.  
     CONSTITUTION: SO 3 -contg. gas 4 is introduced into body 1 of the economizer at about 430°C and cooled to 180W220°C suitable for the next SO 3  absorbing process. On the other hand, boiler feed water 9 enters heating tube 5 at 105°C and flows in the countercurrent direction of gas 4 to be heated. In a conventional economizer, the surface temp. of fin metal becomes 120W130 C in the vicinity of SO 3 -contg. gas outlet part 3 owing to boiler feed water 9 fed at low temp. to dew sulfuric acid. In the exonomizer of this invention, tube 11 is put in each tube 5 at the lower side stage with aluminum foil 12, etc. in-between to raise heat transfer resistance in the tube. Thus, the surface temp. of fin metal can be raised to above the dew point of sulfuric acid.

Abstract: PURPOSE:To enhance the efficiency in conveying a particulate material by a method wherein the material is fed into distrbuting pipes by jetting air after weakening the moving inertia of particles. CONSTITUTION:A mixed flow A of air and the particulate material is conveyed through an inflow pipe 16 and collides against a conical collision body 18 at the outlet of the pipe 16. Then, the air flows upwardly, while the particulate material rebounds and again collides with the throttle part of a casing 12 to reduce the inertia thereof. Then, an air flow B is introduced via an air-injecting port 14 provided at the lowermost part of the throttle part of the casing 12, whereby the particulate material is brought up to the height of the distributing pipes 20, 22 while maintaining the airflow velocity in the cross section of the casing 12 to be higher than the end velocity of the particles of the material. In this case, since the particles flows upwards at a relatively low velocity of about 1-5m/sec, they are in such a condition as to be mixed and distributed uniformly. Accordingly, a mixed-phase flow C containing the amount of the particles proportional to the flow rate of air through the distributing pipes 20, 22 flows into the pipes 20, 22 to accomplish accurate distribution of the particles.

Abstract: PURPOSE:To prevent an overheating of a molybdenum lead foil by providing a visible ray permeable infrared-ray reflection membrane at the center of a bulb opposing to a filament, and forming the outer surface of the bulb near a sealing member in an uneven surface. CONSTITUTION:While an infrared-ray reflection membrane 6 is formed at the center of a bulb 1 opposing to a filament 5, an infrared-ray scattering surface 7 is formed on the glass surface near a sealing member 2 of the bulb 1. As a result, since the infrared rays of the light incident from the filament 5 to the bulb 1 are scattered over the bulb surface, and emitted to the outside, the infrared rays incident to the sealing member 2 are reduced extremely. Consequently, the temperature of molybdenum lead foils 3 can be lowered, a fear of reducing the airtightness owing to the oxidation of the lead foils is eliminated to reduce the early deterioration of airtightness, and the service life is extended extensively.
