IPC: B22F3/26
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a device which is capable of continuously impregnating porous members with a liquid substance in a short time. SOLUTION: This impregnating device is provided with an endless carrying device 40 which goes in and out of an impregnating tank while being loaded with the porous members 50 and proceeds in the tank while diving under the liquid surface of an impregnating liquid 11 in the impregnating tank 10 storing the impregnating liquid. In the impregnating device, injection nozzles 22 blowing up the impregnating liquid and a circulating system 20 of the impregnating liquid are installed at the bottom of the impregnating tank 10 under the carrying device, and a dome 12 provided with an entrance and an exit for the carrying device and the porous members covers thereabove. Owing to action of a liquid current blowing up, positive pressure acts on a lower side of the porous member and negative pressure acts on an upper side thereof and thereby impregnation time is shortened.

Title: Radial-flow filtration apparatus with inflow ring
Inventor: IWASAKI KATSUMI
IPC: B01D29/62
Filed: 1983-05-19
Abstract: PURPOSE:To suppress the expansion of an occupancy area in a radial-flow filtration apparatus by providing an inflow ring, which is located between an inflow chamber and an original water supply pipe at the lower part of a filtration tank and is communicated with each other, along the shell of the tank. CONSTITUTION:An inflow ring 24 controls the flow of the original water and introduces the water into an inflow chamber 12. Namely, the flow direction of the original water flowing in from an original water supply tube 19 is changed by hitting against the wall of the inflow ring 24, and the energy of the flow is reduced at the same time. Then the original water flows uniformly upward in the inflow chamber 12. While the original water introduced into the inflow chamber 12 passes through a filter medium supporting wall 15 on the inflow side, a granular filter medium 17, and a filter medium supporting wall 16 on the outflow side, the suspended matter is removed to obtain the treated water. The treated water is introduced into a treated water chamber 14, then introduced into a rectifying pipe 26 from its lower end, sent upward, and discharged from a treated water recovering pipe 20 at the upper part and recovered. Consequently, the expansion of the occupancy area in the radial-flow apparatus can be suppressed.

Abstract: PURPOSE: To obtain high purity hydrogen gas by purifying hydrogen gas contg. impurity gas by a pressure swing adsorption method comprising specified five processes.  
     CONSTITUTION: Three adsorption towers A,B,C, packed with an adsorbent such as zeolite or activated carbon are placed side by side as one unit. Valves 3a, 4a, 5a are closed, and raw gas consisting of hydrogen gas and one or more kinds of impurity gases is fed into tower A through pipe P 1  and valve 1a to allow the impurity gases to be adsorbed. The purified hydrogen gas is recovered as product gas through valve 2a and pipe P 2 , and part of the gas is used to finish-purge tower B. Next valve 3a alone is opened to evacuate tower A and most of the impurity gases are exhausted through pipe P 3 . By opening valves 3a,4a pipe P 4  and the outlet side of tower A are communicated to let raw gas flow into tower A countercurrently to purge the residual impurity gases in tower A. Valve 4a is then opened to commuincate pipe P 5  and the outlet side of tower A, thereby coutercurrently introducing product gas from pipe P 2  through pipe P 5  and valve 4a to perform finish purge. Raw gas is introduced into tower A through pipe P 1  and valve 5a and pressurized. The above processes are carried out in towers A,B,C in order.

Abstract: PURPOSE:To prepare a rough shaped billet with a prescribed web height from a slab of a comparatively narrow breadth, by installing a pass for rolling only the web in front of a main rolling pass, at forming a rough shaped billet to be finished into such a steel shape as an H-beam. CONSTITUTION:A blank slab is subjected to a centering rolling work for forming a groove 5 by a box caliber 11; a part 9 equivalent to a flange is then formed by a caliber 8. Thus formed slab 10 is 90 degrees turned and is then passed through a caliber 15 whose rolling face is formed into a taper; hereby, a rollig reduction is given to the slab so as to make a part 17 equivalent to the web elongate only in the direction of breadth. These passes by the calibers 8 and 15 are alternately several times repeated; then, the slab is passed through a box caliber 11 having a flat bottom face, and is fed to the final forming pass. By thus repeating the rolling pass with the caliber 15 for widening the web height, various kinds of rough shaped billets are prepared from a slab of a comparatively narrow breadth.

Title: Combustion method for powder fuel
Inventor: NARITA KIICHI
IPC: C10L5/00
Filed: 1980-06-26
Abstract: PURPOSE: To obtain a good combustion efficiency and combustion rate with a powder fuel having bad burning properties, by blending a slow-burning powder fuel with a rapid-burning powder fuel and blowing them into a furnace together with a carrier gas.  
     CONSTITUTION: A slow-burning powder fuel containing 10wt% or more combustible volatile matter, e.g. coke for a blast furnace, is blended with 50wt% or more rapid-burning powder fuel containing 20wt% or more combustible volatile matter, e.g. Risgow coke, to blow them into a furnace together with a carrier gas. When a blending ratio of the rapid-burning fuel to the slow-burning fuel is less than 40wt%, the combustion ratio is hardly improved. After the blending ratio reaches 40wt%, the combustion ratio is abruptly raised and, in particular, the mixed fuel blended with 50wt% or more raiod-burning fuel shows an excellent combustion ratio hardly inferior to a sole rapid-burning fuel.
